Answer:

(4 \pi+26)\ in

Step-by-step explanation:

we know that

The perimeter of the figure is equivalent to the perimeter of a rectangle plus the perimeter of semicircle minus the length side of 8 inches

step 1

<u>Find the perimeter of rectangle</u>

the perimeter of rectangle is equal to

P=2(b+h)

we have

b=8\ in

h=9\ in

substitute

P=2(8+9)=34\ in

step 2

<u>Find the circumference of semicircle</u>

the of circumference of semicircle is equal to

C=\frac{1}{2}\pi D

we have

D=8\ in

substitute

C=\frac{1}{2}\pi (8)=4 \pi\ in

step 3

Find the perimeter of the figure

34\ in+4 \pi\ in-8\ in=(4 \pi+26)\ in

OLga [1]
Remember PEMDAS 
Do parentheses, results in 25. So whats left is 87-25*(-3)+9
Then you multiply -25 by -3, answer is 75.        87+75+9
Add all of them up.                                                171

Carbon-14 has a half-life of 5,730 years. If a sample contained 70 mg originally, how much is left after 17,190 years?
kow [346]

17,190 / 5,730 = 3. This means we must divide 70mg in half 3 times

70 / 2 = 35

35 / 2 = 17.5

17.5 / 2 = 8.75

There will be 8.75 mg left after 17,190 years.

Semenov [28]

Answer:

What 108 represents here is that the total number of phones she has to fix each week is 108 phones

Step-by-step explanation:

The linear equation is

P = 108-23d

compare this with the general form;

y = mx + c

we have;

P = -23d + 108

We can see that 108 represents the y-intercept in this case

The x-value at the y-intercept is 0

So what this mean is that the number of phones she has to fix each week is 108
