Which give you the answer of 151.58
Answer:
1021
Step-by-step explanation:
1+1=2 and it needs to add up to 4 so you add in another 2 in the only place left for it to go which is in the tens place because the first and last number have to be the same and 0 has to go in the hundreds place.
Answer:
<u>Hanna is 8 years old.</u>
Step-by-step explanation:
Hanna = x
Tina = 4x
Sum = 40.
Hanna =?
Hanna + Tina = 40
4x + x = 40
5x = 40
x = 40/5
x = <u>8</u>.
Hanna is <u>8 years</u> old.
C = 2pi r= 2 (3.14) (27) = 169.56
Let XY = x
169.56 / 360 = x / 60
360x = 169.56 * 60
360x = 10173.60
x = 28.26
x = 28.3
Answer is C. 28.3 cm
