Answer:
Step-by-step explanation:
a) 7(25) + 4(10) + 37(5)
7(20) +7(5) +4(10) + 5(30) + 5(7)
1.40 + 35 + 40 + 1.50 + 35
1.75 + 40 + 1.85
3.60 + 40
4.00 = 400% of $1
b) 50 + 7(10) + 1.02
50 + 70 + 1.02
1.20 + 1.02
2.22 = 222% of $1
c) 2.00 + 13(5) + 71
2.00 + 5(3) + 5 (10) + 71
2.00 + 15 + 50 + 71
2.00 + 65 + 71
2.00 + 1.36
3.36 = 336% of $1
A has a higher percentage of dollar because 400%>336%>222%

Answer:
There are 16 nickels and 15 dimes.
Step-by-step explanation:
let x = number of dimes
let y = number of nickels
x + y = 31
.1x + .05y = 2.30
Solve x + y = 31 for x
x = 31 - y
multiple the second equation by 100 to eliminate the decimals.
10x + 5y = 230 Substitute 31 - y for x
10(31-y) + 5y = 230 Distribute the 10
310 -10y + 5y = 230 Combine like terms
310 -5y = 230 Subtract 310 from both sides
-5y = -80 Divide both sides by -5
y = 16
There are 16 nickels.
Plug in 16 for y to solve for x
x + y = 31
x + 16 = 31 Subtract 16 from both sides
x = 15
There are 15 times.
Check:
10x + 5y = 230
10(15) + 5(16) = 230
150 + 80 = 230
230 = 230

Jodie wanted to match Mandy's obstacle course record of 68.2 seconds. She had already spent 40 1/4 seconds on wall climbing and 12.84 seconds on the ropes. How much time did she have left to match the record?
A. 12.20 seconds
B. 15.11 seconds
C. 53.09 seconds
D. 55.36 seconds
Answer:

B.
Without doing any calculations, compare expression A to expression B. 56×250 (13×250)+(12×250) Choose the words to complete the comparison. Expression A is expression B.
Answer:
The distributive law of multiplication states that when a number is multiplied with the sum is equal to the number multiplied by each addend with the number and then sum of the both products.
by example a*(b+c)=(a*b) + (a*c)
Here the expression A is (5/6)*250
the expression B is ( 1/3 × 250 ) + ( 1/2 × 250 )
expression B is ( 1/3 × 250 ) + ( 1/2 × 250 )
=250*(1/3+1/2) applying distributive law of the multiplication
=250*((2+3)/6)
=250*(5/6)
=(5/6)*250
Therefore the expression A is equal to the expression B.

Mr. Townsend needs to make 13 pairs of butterfly wings for costumes for a play. Each pair of wings is made with yard of fabric. The fabric costs $8 per yard.
You'll apply properties of multiplication in the following steps to find the total cost of the fabric.
1. Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of wings. (2 points)
2. Multiply the amount of fabric by the price per yard to find an expression for the total cost.(2 points)
3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with. (3 points)
4. Simplify your expression to find the total cost. Show your work. (3 points)
Answer:
Step-by-step explanation:
1. 13 x 8 - One pair of wings needs one yard of fabric, which is $8. Therefore, one pair of wings cost $8.
2. 104 - The result of multiplying 13 x 8
3. 13 x (4 x 2) - This is easier because smaller numbers are more familiar and understandable to our brains.
4. 13 x (4 x 2)
13 x 4 = 52
52 x 2 = 104

Step-by-step explanation:
One boxcar of a model train measures 6 inches in length. The actual length of a boxcar is 606 inches (50.5 ft). What is the scale of the model?
To find the scale of the model train boxcar, we need to determine the ratio of the actual size of the boxcar to the size of the model. We can do this by dividing the actual size of the boxcar by the size of the model:
scale = actual size / model size
Plugging in the values from the problem, we get:
scale = 606 inches / 6 inches
Simplifying this expression gives us:
scale = 101
So, the scale of the model train boxcar is 101. This means that for every 1 inch of the model, there are 101 inches in the actual size.

Answer: There are between 9 and 10 ounces of fluid in container B.
Step-by-step explanation: There are between 9 and 10 ounces of fluid in container B. To find the number of ounces in container B, divide the number of ounces in container A by 8. This gives 76 / 8 = <<76/8=9.5>>9.5 ounces. Since 9.5 is between 9 and 10, the correct answer is "There are between 9 and 10 ounces of fluid in container B."

A plant will become invasive when the number of plants reaches 10,000. Model the situation with an exponential growth function. How many years will it take for the plant to become invasive? Explain how you found the situation.
It would take 43 years for the plant specie to become invasive.
How many years would it take the plants to become invasive?We know that the increase of the plant is following the exponential function and this can be seen from the question that we have here. We now have to create a model that we can use to solve the question.
Using
Pt = Poe^rt
Pt = population at time t
Po = initial population
r = population growth rate
t = time taken
Then;
10000 =500e^0.07t
10000/500 = e^0.07t
20 = e^0.07t
ln20 = 0.07t
t = ln20/0.07
t = 43 years

Find the distance between the points (6.6,7.9) and (6.6, 4.7).
To find the distance between the points (6.6,7.9) and (6.6,4.7), we can use the distance formula:
distance = √((x2 - x1)^2 + (y2 - y1)^2)
Plugging in the coordinates of the two points, we get:
distance = √((6.6 - 6.6)^2 + (4.7 - 7.9)^2)
Simplifying this expression gives us:
distance = √((0)^2 + (-3.2)^2)
Which simplifies to:
distance = √(10.24)
Finally, taking the square root of both sides gives us:
distance = 3.2
So, the distance between the points (6.6,7.9) and (6.6,4.7) is approximately 3.2.
If x and y vary directly and y is 3 when x is 4, find y when x is 12.
Answer: Y is 9 when X is 12.
Step-by-step explanation:
Here is how you do it.
1. Make a table of x and y
x: 4,
y:3,
2. Keep continuing the table with list of numbers until x=12
x:4,8,12
y=3,6,9.
As you can see, when x is 12 y is 9.

Which graph represents this system?
2 x minus 5 y = negative 5. y = two-fifths x + 1.
A) On a coordinate plane, 2 lines go through points (negative 5, negative 1) and (0, 1).
B) On a coordinate plane, a line goes through (0, 1) and (5, 3) and another goes through (0, negative 5) and (5, negative 3).
C) On a coordinate plane, a line goes through (0, 1) and (5, 3) and another goes through (0, 1) and (5, negative 1).
D) On a coordinate plane, a line goes through (0, 1) and (negative 5, negative 1) and another goes through (negative 5, negative 3) and (0, negative 5).
Answer:
Option A.
Step-by-step explanation:
When x = - 5, y = - 1,
lhs of (1) = - 10 + 5 = - 5
lhs of (2) = - 1 + 2 = 1
When x = 0, y = 1,
lhs of (1) = 0 - 5 = - 5
lhs of (2) = 1 - 0 = 1
