Answer:

28.27

I searched it up

so the formula to find the area of a circle is A = pie x r or (radius)^2 so the radius is just squared.
so the radius of the circle is 3 so you would square that.
pie is 3.14(rounded)
A = 3.14(pie) x 3^2
A = 3.14 x 9
A = 28.26
my calculator got that which is different from the other person's answer but i hope this will help you!

Bill baked 16 cookies with 2 scoops of flour. With 4 scoops of flour, how many cookies can Bill bake? Assume the relationship is directly proportional.

Answers

Answer:

Let c = the number of cookies

cookies/scoops of flour: 12/2 = c/3

Cross multiply.

2c = 36

c = 18 cookies

Step-by-step explanation:

Answer:

32 cookies.

Step-by-step explanation:

Find how much cookies Bill can bake with just 1 scoop of flour:

2 scoops of flour = 16 cookies

1 scoop of flour = 16 ÷ 2 = 8 cookies

Now, find 4 scoops of flour.

4 scoops of flour = 8 x 4 = 32 cookies

Using the graph above identify the constant of proportionality between the number of shirts and how much they cost? Hint: simplify your answer
A. K=80
B. K=20
C. K=10
D. k=8

Answers

Answer:

We conclude that the constant of proportionality between the number of shirts and how much they cost is:

k = 8

Hence, option 'D' is correct.

Step-by-step explanation:

We know that when 'y' varies directly with 'x', we get

y ∝ x

y = kx

k = y/x

where k is called the constant of proportionality

Given the points

(10, 80)(20, 160)(50, 400)

For (10, 80)

substituting y = 80 and x = 10 in the equation

k = y/x

k = 80/10 = 8

For (20, 160)

k = y/x

k = 160/20 = 8

For (50, 400)

k = y/x

k = 400/50 = 8

It is clear that the value of k is the same for all the points.

Thus, the value of k = 8

Therefore, we conclude that the constant of proportionality between the number of shirts and how much they cost is:

k = 8

Hence, option 'D' is correct.

14.4 A Book and a Cake A book costs $45. Sales tax on the book is 7%. Write two different expressions that represent the final cost of the book in dollars. Pne of the expressions should use only a single multiplication and no other operations.
A cake that costs $32 is on sale for 15% off and there are no taxes. Explain why the expression (0.85).32 represents the final price of the cake in dollars
(0.85). 32 represents the final price of the cake in dollars because...

Answers

Answer: 1. $45*1.07 | $45(1.07) 2. (0.85)*32 represent the final price of the cake in dollars because (0.85) is the 15% off in decimals.

Step-by-step explanation:

1 if you multiply 45 by 1.07 it will be 48.15 and that's the final cost of the book, same with $45(1.07) is just another way to represent the multiplication.

2 As I said the 0.85 represent the 15% off, and when you multiply it will be less.

Answer: 50 feet

Area = Length × Breadth

2000 = x × 0.8x

0.8x² = 2000

x² = 2000/0.8

x = ✓2500

x = 50

Therefore, the length is 50feet

Chris had 30 minutes to do a three-problem quiz. He spent 11 3/4 minutes on question A and 4 1/2 minutes on question B. How much time did he have left for question C?

Answers

Answer:Chris spent 13 3/4 minutes on question C

Step-by-step explanation:

First let's write an equation:

We know 30 is the total and we are trying to find a part, and 11 3/4 is a part and 4 and 1/2 is a part

So:

30=11 3/4 + 4 1/2 + x

30=16 1/4 + x

- 16 on both sides(to find what x equals to)

13 2/4=x

X=13 3/4
