What is the value of √x+3 when x = 15? 15√3 9√2 6√3 3√2

Answer:

Height of the pine tree = 60 in.

Step-by-step explanation:

Since, triangle formed by the tip of the tree and tip of the shadow of the tree will be similar to each other,

By the property of similarity, corresponding sides of the similar triangles will be proportional.

[tex]\frac{x}{20}=\frac{36}{d}[/tex]

If d = 12 inches,

[tex]\frac{x}{20}=\frac{36}{12}[/tex]

x = [tex]\frac{20\times 36}{12}[/tex]

x = 60 in.

Therefore, height of the pine tree will be 60 in.

Answer:

B m = 1/2 y-int = -1

Step-by-step explanation:

at x = 0, y=-1 so that is the y-intercept

to find the slope, use the slope formula m=(y2-y1)/(x2-x1)

m=(0--1)/(2-0)

m=1/2

Jake wants to go to a lil uzi vert concert. A lil uzi vert concert ticket cost $320. The backstage pass is only $400, so Jake pays for that instead. He later figured out that he wanted to lose 50 pounds before the concert in 6 months and for every time he goes to the gym he has to pay $10 he only goes to the gym 8 times and his bank account has $500 on it. How much money did he have left over after going to the gym 8 times? - PS don't worry about this question its just a fake scenario i made for the second part of your question hope this helps!!!

Answer:

17 years

Step-by-step explanation:

In order to calculate this, we need to create an equality equation. In this scenario, we have the fixed values which are the total population and the rate of growth, and we also have one variable which is the number of years. We can use these values to create the following equation.

2,425 + 27x = 1,813 + 63x

Now that we have the equation we can solve for x to calculate how many years it will take for them to be the same population.

2,425 + 27x = 1,813 + 63x   ... subtract 1,813 and 27x from both sides

612 = 36x   ... divide both sides by 36

17 = x

Finally, we can see that both populations will be the same after 17 years.

Answer:

I think Linear but i am not sure

Step-by-step explanation:

A linear function is a function with standard form y = mx + b, where m is the slope and b is the y-intercept, and whose graph looks like a straight line. There are other functions whose graph is not a straight line. These functions are known as nonlinear functions and they come in many different forms.

Answer:

11.02

Step-by-step explanation:

Remember to multiply the markdown and origin price and then sub what you get from the original price to get an answer. Goodluck

Answer:

$11.02

Step-by-step explanation:

1. Take the original price and multiply it by 33%.

16.45 * 0.33 = 5.4285

2. Round 5.4285 to two decimal places

5.43

3. Take your discount and subtract it from the original price.

$16.45 - $5.43 = $11.02

Answer: Either A or B because you have to add the amount you have to get the total amount she spent.

Answer:

y = 19.99x + 30

Step-by-step explanation:

y = 19.99x + 30

The x represents the number of hours, and because it costs 19.99 per hour, the coefficient before the x will be 19.99. The y-intercept is the fee because it doesn't change with the x.

The two of the possible solutions to the equation sin(5x - π) = (√2)/2 are,

⇒ (π/4, 7π/4).

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Here, The given equation is;

sin(5x - π) = (√2)/2

Now, We can write 2 as √2 × √2

So, We get;

sin(5x - π) = √2/√2*√2

sin(5x - π) = 1/√2

Taking sin⁻¹ on both side,

sin⁻¹ (sin(5x - π)) = sin⁻¹ (1/√2)

5x - π = sin⁻¹ (1/√2)

Hence, From the trigonometry table we know that sin⁻¹ (1/√2) = π/4

Thus,

5x - π = π/4

5x = π + π/4

5x = 5/4π

Divide by 5 on both side, we get

x = π/4

Now, since x < 2π, then it means it is in the fourth quadrant. Thus;

x = 7π/4

So, the two of the possible solutions to the equation sin(5x - π) = (√2)/2 is (π/4, 7π/4).

Answer:

20 cakes

Step-by-step explanation:

Given

28 cakes in 7 days

Required

Determine the number of cakes in 5 days

Represent the required with x. The question illustrates proportionality.

First, we need to represent the given and required as a ratio

[tex]28 : 7 = x : 5[/tex]

Convert ratios to fraction

[tex]\frac{28}{7} = \frac{x}{5}[/tex]

[tex]4 = \frac{x}{5}[/tex]

Solve for x

[tex]x = 4 * 5[/tex]

Answer:

(- 1, - 4 ) and r = 5

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

To obtain this form from the given equation use the method of completing the square.

Given

x² + y² + 2x + 8y = 8 ( rearrange by collecting x and y terms )

x² + 2x + y² + 8y = 8

To complete the square

add ( half the coefficients of the x/ y terms )² to both sides

x² + 2(1)x + 1 + y² + 2(4)x + 16 = 8 + 1 + 16

(x + 1)² + (y + 4)² = 25 ← in standard form

with centre (h, k ) = (- 1, - 4 ) and r = [tex]\sqrt{25}[/tex] = 5

Answer:

24 miles

Step-by-step explanation:

In order to calculate Judy's estimation, we would simply have to multiply the actual distance in kilometers of the tour by the number of miles that Judy believes are in a single mile. This would give us Judy's estimation for how long the tour would be in miles.

40 km. * 0.6 miles = 24 miles

Finally, we can see that Judy's estimation would be that the tour is 24 miles long. Using Judy's believed conversion rate.

I think the 4th line plot would not be true

Step-by-step explanation:

We could calculate the range and median.

A line plot, also known as a dot plot, is a type of graph that displays the distribution of a set of data. It consists of a number line with dots or X's placed above each data value to represent how many times that value appears in the data set.

Using the stem-and-leaf plot in the diagram, below, write out each data points given, which are:

68, 70, 80, 86, 88, 88, 96, 96, 97, 97, 98, 98, 99, 100, 100, 100, 100, 100

The line plot for these data would have the following frequency for each data point:

68 - 1 dot

70 - 1 dot

80 - 1 dot

86 1 dot

88 - 2 dots

96 - 2 dots

97 - 2 dots

98 - 2 dots

99 - 1 dot

100 - 5 dots

The line plot is shown in the diagram below.

Range = 100 - 68 = 32

Median = 97

Therefore, We could calculate the range and median.

Answer:

30%

Step-by-step explanation:

I apologize if I am incorrect

Answer:

70%

Step-by-step explanation:

set up an equation for the word problem that looks like this: 50x = 35

and solve by dividing both sides by 35

50x ÷ 50 = x

35 ÷ 50 = .7

.7 = 70%

x = 70%

Answer:150%

Step-by-step explanation:because 50% increases

The number of houses sold this month are -

y = 3x/2.

In mathematics →

Given is that compared to last month, there was a 50% increase in the number of houses sold this month.

Assume that the number of houses sold of previous moth were [x]. Then, we can write -

y = {x} + 50% of {x}

y = {x} + (50/100) × {x}

y = {x} + {x/2}

y = 3x/2

Therefore, the number of houses sold this month are -

y = 3x/2.

$21.28

Step-by-step explanation:

First, find 12% or 19 -- this is 2.28

Next, take the total (19) and add 2.28 to it.

$19+$2.28=$21.28

okay so it says Sophia's friend has saved $118 so she already knows she has $118 and then the next step is to figure out about Part B so she does not know how many songs you can afford to buy so the expression in Part B whatever the expression is if you figured out the answer to Part B and there's a number what you want to do what you would want to divide that number into 118 to see how how many equal groups you can make and you don't want to go overboard 18 so what you would want to do it if you would want to do if you figure out the number to expression be in the boring part B they don't want to take that and keep making a go go to that until you reach 118 and then you would get your total

Answer:

x = -6

Step-by-step explanation:

you want to solve the aswer so you wanna solve for whats in the parenthesis so your new equation should look like this:

8x + 48 = 3

you want to subtract 48 from both sides  your new equation should look like this:

8x = -45

now you want to get x by itself and your new equation should be:

x = -6
