Answer:
o.45
Step-by-step explanation:
any time you have a precent just put 0. infront of the number.
R-7=7 add the seven from both sides, leaving the r alone, because this is what you are trying to find. Thus the answer is r=14.
<span>A 15° sector in a circle has an area of 11.9 m2. What is the area of the circle?
The area of the circle will be found as follows:
the fraction of the sector=15/360=1/24
the area of the circle will be:
area=(fraction of the circle)/(fraction of the sector)*(area of the sector)
=1/(1/24)</span>×11.9
=285.6 m²
Answer:
Simple interest = PRT/100
300 = 150 x 4 x T/100
2 x 100/4 = T
Therefore T = 50 years
Hope this helps!
