Answer:
<h2><em><u>
15.71 is the perimeter.</u></em></h2>
Step-by-step explanation:
Perimeter = Circumference
<em><u>Step 1. Know and recognize what you have</u></em>
C = pi*d
pi = 3.142
d = 10
<em><u>Step 2. Solve for the circumference of whole circle</u></em>
C = 3.142*10
C = 31.42
<em><u>Step 3. Solve for the questions answer</u></em>
C of semicircle = 31.42/2
<h2><em><u>
C of semicircle = 15.71</u></em></h2><h2><em><u>
</u></em></h2>

Answer:
check question i have not understand
Answer:
A 2:1
B 1:2
Step-by-step explanation:
If there is 24 students and 8 are girls, then 24 - 8 tells you how many are boys.
24 - 8 = 16.
There are 16 boys.
If there is 16 boys and 8 girls, the ratio would be 2 : 1 or 2/1 or 2 because 16 and 8 have a common factor of 8, so both sides can be divided by 8.
Hence the 8 : 2.
Ratios are commonly expressed with a colon, so that is going to be the symbol I'm using to differenciate the numbers.
We can just reverse the ratio since the original was boys to girls, but it is now girls to boys.
1:2
What equations? I see no equations. Do you have a picture, if take a picture
128% as a fraction
128% ÷ 100% = 1.28
1 is a whole number while the .28 can be converted into a fraction.
1.28 = 1 28/100
28/100 can be simplified by 2 ⇒ 14/50
14/50 can be simplified by 2 ⇒ 7/25
128% as a fraction is 1 7/25
