Michelle’s mom is letting her paint her room pink. What formula would she use to figure out how much paint she needs.
24 is 31.25% of what number? Prove your answer in the show your workbox.
Pls explain it I'm giving brainlienesss
Answer:
76.8
Step-by-step explanation:
1. We assume, that the number 31.25 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 31.25, so we can write it down as 100%=31.25.
4. We know, that x% equals 24 of the output value, so we can write it down as x%=24.
5. Now we have two simple equations:
1) 100%=31.25
2) x%=24
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=31.25/24
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 24 is what percent of 31.25
100%/x%=31.25/24
(100/x)*x=(31.25/24)*x - we multiply both sides of the equation by x
100=1.3020833333333*x - we divide both sides of the equation by (1.3020833333333) to get x
100/1.3020833333333=x
76.8=x
x=76.8
now we have:
24 is 76.8% of 31.25
Answer:
76.8

Step-by-step explanation:
The value of a baseball player's rookie card began to increase once the player retired. When he retired in 1997 his card was worth $4.51 The value has increased by $1.02 each year since then. Express the relationship relating the value of the card y in dollars and the number of years x the player has been in retirement with an equation. Is the relationship between x and y proportional? What was the value of the card in 2008?
Step-by-step explanation:
When he retired in 1997 his card was worth $4.51 The value has increased by $1.02 each year since then.
Express the relationship relating the value of the card y in dollars and the number of years x
y = $1.02 x + $4.51
Is the relationship between x and y proportional?
Yes. This is because as x increases, the value of y also increases.
What was the value of the card in 2008?
Number of years from 1997 to 2008 = x = 11
y = $1.02 x + $4.51
y = $1.02 (11) + $4.51
y = $ 11.22 + $4.51
y = $ 15.73
Two angles are complementary. The measure of angle W is four times the

The radius of Circle A is 6 mm. The radius of Circle B is 4 mm greater than the radius of Circle A. The radius of Circle C is 2 mm greater than the radius of Circle B. The radius of Circle D is 3 mm less than the radius of Circle C. What is the area of each circle? How many times greater than the area of Circle A is the area of Circle D
Answer:
Area of circle A =113.14 mm²
Area of circle b = 314.29 mm²
Area of circle C = 452.57 mm²
Area of circle A = 254.57 mm²
2.25 times
Step-by-step explanation:
Area of a circle = nr²
where n = 22/7
r = radius
Circle A's radius = 6mm
Circle B's radius = 6mm + 4mm = 10mm
Circle C's radius = 10mm + 2mm = 12mm
Circle D's radius = 12mm - 3mm = 9mm
Area of circle A = (22/7) x 6² = 113.14 mm²
Area of circle b = (22/7) x 10² = 314.29 mm²
Area of circle C = (22/7) x 12² = 452.57 mm²
Area of circle A = (22/7) x 9² = 254.57 mm²
Number of times the area of circle D is greater than that circle A = Area of circle D / Area of circle A
254.57 mm² / 113.14 mm² = 2.25 times
what is the disadvantage and advantage
Answer:

What is the solution to the system of equations?
x = -4y
3x + 2y = 20
Answer:
(x, y) = (8, -2)
Step-by-step explanation:
Substitute:
3(-4y) + 2y = 20
-12y + 2y = 20
-10y = 20
y = -2
x = -4(-2) = 8

Have a great day <3
Please helpppp :< here is 25 points
Answer:
function b
Step-by-step explanation:
When its asking for which function has a greater rate of change its asking for which slope has a greater value
the slope is calculated by change in y over change in x
for function a, as y goes up 2 x goes up 1
so the slope ( rate of change) is 2/1
for function b is y goes up 3 x goes up 1
so the slope (rate of change) is 3/1
3/1 is greater than 2/1 so function b has a greater rate of change

A passenger train travels between two
cities at a constant speed. After 6 hours,
it has traveled 450 miles. After 9 hours, it
has traveled 675 miles. Which equation
shows the relationship between the
distance d in miles and the time t in hours?
Answer:
The train travels 75 mph.
Step-by-step explanation:
Hope this helps!
Answer:
(75, 1)
Step-by-step explanation:
One way we can figure out how fast the train goes, is bylooking at what we have. We know that the train travels 450 miles in 6 hours. When we divide, we get 75. So, we know that the train is going at 75 miles per hour. We can check our work by looking at the second relationship on there. When 675 is divided by 9, we get 75. So for every hour, the train travels 75 miles.
I hope that this helps you out :)
