What is the exact circumference of the circle?

cestrela7 [59]

Hello!

What is the exact circumference of the circle?

10π feet

20π feet

40π feet

60π feet

Solving: Using the data (Circle with center A and diameter of 20 feet labeled).

diameter = 2*radius

$20 = 2*r$

$2\:r = 20$

$r = \dfrac{20}{2}$

$\boxed{r = 10\:ft}$

Formula: (Circle length)

$\boxed{C = 2* \pi *r}$

Now, replace in the circumference length formula:

$C = 2\:\pi *r$

$C = 2\:\pi *10$

$\boxed{\boxed{C = 20\:\pi\:ft}}\end{array}}\qquad\quad\checkmark$

Answer:

B. 20π feet

$\underline{The\:exact\:circumference\:of\:the\:circle\:is\:\:20\:\pi\:ft}$

Sophia did push-ups every day for 7 days. Each day after the first day, she did 5 more push-ups than the day before. In total sh

Dafna1 [17]

Answer:

Push- ups on last day = 40

Step-by-step explanation:

According to given conditions:

Let push-ups on:

1st day = x

2nd day = x + 5

3rd day = x + 10

4th day = x + 15

5th day = x + 20

6th day = x + 25

7th day = x + 30

Now total push ups = adding all

x + x + 5 + x + 10 + x + 15 + x + 20 + x+ 25 + 30 + x = 175

By adding same terms:

7x + 105 = 175

Subtracting 105 from both sides

7x + 105 - 105 = 175 - 105

7x = 70

Dividing both sides by 7 we get:

x = 70/7

x = 10

Now calculating push-ups on days:

1st day = x = 10

2nd day = x + 5 = 10 + 5 = 15

3rd day = x + 10 = 10 + 10 = 20

4th day = x + 15 = 10 + 15 = 25

5th day = x + 20 = 10 + 20 = 30

6th day = x + 25 = 10 + 25 = 35

7th day = x + 30 = 10 + 30 = 40

So number of push-ups on 7th (last) day is 40.

I hope it will help you!

Two equations are given below: m + 4n = 8 m = n - 2 What is the Solution ?

Sophie [7]

M+4n=8
m=n-2
we see that m=n-2
so we can subsitute 'n-2' for m in the first equation
(n-2)+4n=8
n-2+4n=8
5n-2=8
add 2 to both sides
5n=10
divide by 5
n=2
subsitute
n=2
m=n-2
m=2-2
m=0

m=0
n=2

the answer is c. 0,2
