Rose's age should be a whole number, we can round 7.8 to the nearest whole number, which is 8.
Let's assume the number of primroses in the vase is p, and the number of celandines is c.
Each primrose has 5 petals, so the total number of primrose petals is 5p.
Each celandine has 8 petals, so the total number of celandine petals is 8c.
According to the given information, the total number of petals is 39. Therefore, we can set up the equation:
5p + 8c = 39 (Equation 1)
Aunt Lily mentions that the total number of flowers is exactly Rose's age. Since Rose's age is not provided, we'll represent it with the variable r.
The total number of flowers is p + c, which is also equal to Rose's age (r). Therefore, we have another equation:
p + c = r (Equation 2)
We need to find the value of r (Rose's age). To do that, we'll solve the system of equations by eliminating one variable.
Multiplying Equation 2 by 5, we get:
5p + 5c = 5r (Equation 3)
Now we can subtract Equation 1 from Equation 3 to eliminate the p term:
(5p + 5c) - (5p + 8c) = 5r - 39
This simplifies to:
-3c = 5r - 39
Now, let's rearrange Equation 2 to solve for p:
p = r - c (Equation 4)
Substituting Equation 4 into the simplified form of Equation 3, we have:
-3c = 5r - 39
Substituting r - c for p, we get:
-3c = 5(r - c) - 39
Expanding, we have:
-3c = 5r - 5c - 39
Rearranging the terms, we get:
2c = 5r - 39
Now we have a system of two equations:
-3c = 5r - 39 (Equation 5)
2c = 5r - 39 (Equation 6)
To solve this system, we can eliminate one variable by multiplying Equation 5 by 2 and Equation 6 by 3:
-6c = 10r - 78 (Equation 7)
6c = 15r - 117 (Equation 8)
Now, let's add Equation 7 and Equation 8 to eliminate c:
-6c + 6c = 10r + 15r - 78 - 117
This simplifies to:
25r = 195
Dividing both sides by 25, we get:
r = 7.8
Since Rose's age should be a whole number, we can round 7.8 to the nearest whole number, which is 8.
Therefore, Rose is 8 years old.

Answer:
[tex]\frac{3}{7}[/tex] < [tex]\frac{3}{5}[/tex]
Step-by-step explanation:
[tex]\frac{3}{7}[/tex] ? [tex]\frac{3}{5}[/tex]
We have to get both fractions with the same denominator to compare them.
[tex]\frac{3}{7}[/tex] = [tex]\frac{15}{35}[/tex]
[tex]\frac{3}{5}[/tex] = [tex]\frac{21}{35}[/tex]
[tex]\frac{15}{35} < \frac{21}{35}[/tex]
So, [tex]\frac{3}{7}[/tex] < [tex]\frac{3}{5}[/tex]
How would I find cos?
When [tex]sin(\theta) = -0.42[/tex] and [tex]\pi < \theta < 3\pi/2[/tex], the value of [tex]cos(\theta)[/tex] is approximately 0.9071.
To find the value of cos([tex]\theta[/tex]) given[tex]sin(\theta) = -0.42[/tex] and [tex]\pi < \theta < 3\pi/2[/tex], we can use the trigonometric identity:
[tex]sin^2(\theta) + cos^2(\theta) = 1[/tex]
Since we are given sin(theta) = -0.42, we can substitute this value into the equation:
[tex](-0.42)^2 + cos^2(\theta) = 1[/tex]
Simplifying:
[tex]0.1764 + cos^2(\theta) = 1[/tex]
Subtracting 0.1764 from both sides:
[tex]cos^2(\theta) = 0.8236[/tex]
Taking the square root of both sides (since cos(theta) is positive):
[tex]cos(\theta) = \sqrt{(0.8236)} \\cos(\theta) = 0.9071[/tex]
Therefore, when [tex]sin(\theta) = -0.42[/tex] and [tex]\pi < \theta < 3\pi/2[/tex], the value of [tex]cos(\theta)[/tex]is approximately 0.9071.

What is the product of (p^3)(2p^2 - 4p)(3p^2 - 1)?
Answer:
Step-by-step explanation:
To find the product of the given expression, we can use the rules of multiplication and apply them to each term within the parentheses:
(p^3)(2p^2 - 4p)(3p^2 - 1)
Expanding the expression, we multiply each term within the parentheses:
= p^3 * 2p^2 * 3p^2 - p^3 * 2p^2 * 1 - p^3 * 4p * 3p^2 + p^3 * 4p * 1
Simplifying further, we combine like terms and perform the multiplication:
= 6p^7 - 2p^5 - 12p^6 + 4p^4
Therefore, the product of (p^3)(2p^2 - 4p)(3p^2 - 1) is 6p^7 - 2p^5 - 12p^6 + 4p^4.
The product of the expressions (p^3)(2p^2 - 4p)(3p^2 - 1) is computed using the distributive property, resulting in 6p^7 - 12p^6 - 2p^5 + 4p^4.
Explanation:To find the product of the given expressions: (p^3)(2p^2 - 4p)(3p^2 - 1), you will need to apply the distributive property, also known as the multiplication across addition and subtraction.
First, distribute p^3 across all terms inside the brackets of the second expression, then do the same with the result across the terms of the third expression.
Steps are as follows:
p^3 * 2p^2 gives 2p^5. p^3 * -4p gives -4p^4. So (p^3)(2p^2 - 4p) gives 2p^5 - 4p^4. Distribute 2p^5 - 4p^4 across all terms inside the brackets of the third expression. 2p^5 * 3p^2 gives 6p^7 and 2p^5 * -1 gives -2p^5. Similarly, -4p^4 * 3p^2 gives -12p^6 and -4p^4 * -1 gives 4p^4.
All together, it results in: 6p^7 - 12p^6 - 2p^5 + 4p^4. That is the product of the initial expressions.

Find the exact value of sec(-135)
The exact value of sec(-135°) is 1.
To find the exact value of sec(-135°), we need to use the relationship between secant and cosine functions.
The secant function is defined as the reciprocal of the cosine function:
sec(theta) = 1 / cos(theta).
We know that the cosine function has a period of 360°, which means that cos(theta) = cos(theta + 360°) for any angle theta.
In this case, we want to find sec(-135°). Since the cosine function is an even function (cos(-theta) = cos(theta)), we can rewrite sec(-135°) as sec(135°).
Now, let's focus on finding the value of cos(135°). The cosine function is negative in the second and third quadrants.
In the second quadrant, the reference angle is 180° - 135° = 45°. The cosine of 45° is equal to √2/2.
Therefore, cos(135°) = -√2/2.
Now, we can find sec(135°) using the reciprocal property:
sec(135°) = 1 / cos(135°).
Substituting the value of cos(135°), we have:
sec(135°) = 1 / (-√2/2).
To simplify further, we multiply the numerator and denominator by -2/√2:
sec(135°) = -2 / (√2 * -2/√2).
Simplifying the expression:
sec(135°) = -2 / -2,
sec(135°) = 1.

An estimate of 20 people took longer than 325 minutes to complete the race.
To estimate the number of people who took longer than 325 minutes to complete the race, we need to use the cumulative frequency distribution.
The cumulative frequency of a class interval is obtained by adding up the frequencies of all the class intervals up to and including that interval. The sum of the frequencies for each class interval is known as the cumulative frequency.In this case, the cumulative frequency distribution is given as follows:
Class Interval | Frequency | Cumulative Frequency250 - 200 | 5 | 5200 - 150 | 12 | 12150 - 100 | 18 | 30100 - 50 | 11 | 4050 - 0 | 4 | 44Total: 50
Now, to estimate the number of people who took longer than 325 minutes to complete the race, we need to look at the cumulative frequency that corresponds to 325 minutes.
From the table, we can see that the cumulative frequency of the class interval 300-400 minutes is 30. This means that 30 people took between 100 and 400 minutes to complete the race.
Therefore, the number of people who took longer than 325 minutes is the difference between the total number of people who took between 100 and 500 minutes and the number of people who took between 100 and 325 minutes. This can be calculated as follows:50 - 30 = 20.
Hence, an estimate of 20 people took longer than 325 minutes to complete the race.

Which number can each term of the equation be multiplied by to eliminate the fractions before solving?
6-3x+=x+5
5
12
Therefore, the value of x that solves the equation is 2/7, after eliminating the fractions and solving the resulting equation.
To eliminate fractions in the equation 6 - 3x + (1/2)x = x + 5, we can multiply each term by a number that will clear the denominators. In this case, the denominator is 2 in the term (1/2)x. The least common multiple (LCM) of 2 is 2 itself, so we can multiply each term by 2 to eliminate the fraction.
By multiplying each term by 2, we get:
2 * (6 - 3x) + 2 * ((1/2)x) = 2 * (x + 5)
Simplifying this expression, we have:
12 - 6x + x = 2x + 10
Now, the equation is free of fractions, and we can proceed to solve it.
Combining like terms, we have:
12 - 5x = 2x + 10
To isolate the variable terms, we can move the 2x term to the left side by subtracting 2x from both sides:
12 - 5x - 2x = 10
Simplifying further:
12 - 7x = 10
Next, we can move the constant term to the right side by subtracting 12 from both sides:
12 - 7x - 12 = 10 - 12
Simplifying again:
-7x = -2
Finally, we solve for x by dividing both sides by -7:
x = (-2) / (-7)
Simplifying the division of -2 by -7 gives us the solution:
x = 2/7

Miguel rolled up his sleeping bag and tied it with string. Estimate about how much string he used.
about ____ inches
OR about ____ feet
Answer:
Assuming Miguel rolled up his sleeping bag tightly and neatly, the length and circumference of the sleeping bag can help us estimate the length of string needed to tie it up.
Let's say the length of the sleeping bag is 6 feet and the circumference (distance around) is 3 feet. To tie it up, Miguel would need to wrap the string around it 2-3 times, depending on how long the string is and how tight he ties the knot.
So, we can estimate that he used about 12-18 feet of string (i.e. 2-3 times the circumference). In inches, that would be about 144-216 inches of string (i.e. 12-18 feet * 12 inches/foot).
Keep in mind that this is just an estimate and the actual amount of string used may vary depending on the factors mentioned above.

Utility company charges.10 cents per kilowatt-hour of electricity what is the daily cost of keeping lit a 50 watt bulb for 9hrs each day
The daily cost of keeping a 50-watt bulb lit for 9 hours each day would be approximately $0.045 (or 4.5 cents).
To calculate the daily cost of keeping a 50-watt bulb lit for 9 hours each day, we need to consider the electricity cost per kilowatt-hour (kWh) and convert the wattage to kilowatts.
First, we convert the wattage of the bulb to kilowatts by dividing it by 1000:
50 watts = 50/1000 = 0.05 kilowatts.
Next, we calculate the total energy consumed by multiplying the power (in kilowatts) by the time (in hours):
Total energy consumed = 0.05 kW * 9 hours = 0.45 kilowatt-hours (kWh).
Now, we multiply the total energy consumed by the cost per kilowatt-hour to find the daily cost:
Daily cost = 0.45 kWh * $0.10/kWh = $0.045.

6, 12, 24, 48, 96, … Each term is 6 more than the previous term. Each term is 12 more than the previous term. Each term is 1/2 the previous term. Each term is 2 times the previous term.
The given sequence can be generated by multiplying each term by 2, starting from the initial term of 6.
The pattern that fits the given sequence 6, 12, 24, 48, 96, ... is that each term is 2 times the previous term.
In the sequence 6, 12, 24, 48, 96, ... there are multiple possible patterns, each resulting from a different rule applied to generate the next term. Let's examine each of the proposed patterns:
Each term is 6 more than the previous term:
Starting with 6, if we add 6 to each term, we get:
6 + 6 = 12
12 + 6 = 18
18 + 6 = 24
24 + 6 = 30
30 + 6 = 36
...
This pattern does not match the given sequence since it does not produce the subsequent terms.
Each term is 12 more than the previous term:
Starting with 6, if we add 12 to each term, we get:
6 + 12 = 18
18 + 12 = 30
30 + 12 = 42
42 + 12 = 54
54 + 12 = 66
...
This pattern also does not match the given sequence.
Each term is 1/2 the previous term:
Starting with 6, if we multiply each term by 1/2, we get:
6 [tex]\times[/tex] 1/2 = 3
3 [tex]\times[/tex] 1/2 = 1.5
1.5 [tex]\times[/tex] 1/2 = 0.75
0.75 [tex]\times[/tex] 1/2 = 0.375
0.375 [tex]\times[/tex] 1/2 = 0.1875
...
This pattern does not match the given sequence.
Each term is 2 times the previous term:
Starting with 6, if we multiply each term by 2, we get:
6 [tex]\times[/tex] 2 = 12
12 [tex]\times[/tex] 2 = 24
24 [tex]\times[/tex]2 = 48
48 [tex]\times[/tex]2 = 96
96 [tex]\times[/tex]2 = 192
This pattern perfectly matches the given sequence. Each term is indeed 2 times the previous term, resulting in the next term.

Answer:
34.45%
Step-by-step explanation:
A tree diagram shows all possible outcomes of two or more events.
Each branch is a possible outcome and is labelled with the probability of that outcome.
Draw lines (branches) to represent the first event (main meal). Write the outcomes on the ends of the branches: "sandwich" and "slice of pizza". Write the given probabilities on the branches.
Draw the next set of branches to represent the second event (side). Write the outcomes on the ends of the branches: "chips" and "veggies with hummus". Write the given probabilities on the branches.
We assume that the events in this scenario are independent, so the probability of the first event happening has no impact on the probability of the second event or the third event happening. Therefore, to find the probability of each combination of events, multiply along the branches.
Sandwich and chips = 35% × 47% = 16.45%
Sandwich and veggies with hummus = 35% × 53% = 18.55%
Slice of pizza and chips = 65% × 47% = 30.55%
Slice of pizza and veggies with hummus = 65% × 53% = 34.45%
Therefore, the probability that Sophie selects a slice of pizza and veggies is 34.45%.
The probability that Sophie selects a slice of pizza and veggies is 34.45%.
Calculating the probability of pizza and veggiesFrom the question, we have the following parameters that can be used in our computation:
Sandwich = 35%Chips = 47%Veggies with hummus = 53%Pizza = 65%The probability of pizza and veggies is calculated as
P = Pizza * Veggies
Substitute the known values in the above equation, so, we have the following representation
P = 65% * 53%
Evaluate
P = 34.45%
Hence, the probability that Sophie selects a slice of pizza and veggies is 34.45%.

The transformed matrix, after interchanging R1 and R2, is:
2 9 4 5
8 -2 1 7
1 4 -4 9
To interchange rows R1 and R2, we swap the positions of the first and second rows in the matrix. This operation can be performed by physically swapping the rows or by using the properties of matrix operations. Let's apply this row operation to the given matrix:
Original matrix:
8 -2 1 7
2 9 4 5
1 4 -4 9
Interchanging R1 and R2, we get:
2 9 4 5
8 -2 1 7
1 4 -4 9
After switching R1 and R2, the modified matrix is:
2 9 4 5
8 -2 1 7
1 4 -4 9
In the transformed matrix, the original first row (8 -2 1 7) becomes the second row, and the original second row (2 9 4 5) becomes the first row. The remaining rows (R3) remain unchanged.
Therefore, R1 and R2 are switched, and the resulting matrix is:

What are the coordinates of the midpoint of the line segment whose end points are (2, 6) and (10, 4)?
The midpoint of the line segment with endpoints (2, 6) and (10, 4) is (6, 5).
To find the midpoint of a line segment, we can use the midpoint formula, which states that the coordinates of the midpoint are the average of the coordinates of the endpoints.
Let's denote the coordinates of the first endpoint as (x1, y1) and the coordinates of the second endpoint as (x2, y2).
In this case, the first endpoint is (2, 6) with coordinates (x1, y1) = (2, 6), and the second endpoint is (10, 4) with coordinates (x2, y2) = (10, 4).
To find the midpoint, we use the midpoint formula:
Midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)
Plugging in the values, we have:
Midpoint = ((2 + 10) / 2, (6 + 4) / 2)
= (12 / 2, 10 / 2)
= (6, 5)
As a result, (6, 5) is the point on the line segment where the endpoints are (2, 6) and (10, 4) respectively.
