We need to represent the numbers of calls symbolically:
Third evening: x calls
First eve: x-6 calls
Second evening: 3x calls
Find x. Add up these three numbers x, x-6 and 3x and equate your sum to 79:
x+x-6+3x = 79. Then 5x=79+6, or 5x = 85. Thus, x = 17.
17 calls on the 3rd night,
17-6 calls on the 1st night, and
3(17) = 51 calls on the 2nd night.
Check! Add together 17, 11 and 51. Do these add up to 79? Yes.
Answer:
The simple interest for 4 months = Rs 240
Step-by-step explanation:
formula:-
simple interest I = [PNR]/100
P - Principle amount
N - Number of years
R - Rate of interest
It is given that, $7,800 at 9.25% for 4 months
<u>To find the simple interest for 1 year</u>
I = [PNR]/100
I = [7800*1*9.25]/100 = 721.5
<u>To find the simple interest for 4 months</u>
4 months = (1 year )/3
4 months interest = 721.5/3 =240.5 ≈ 240
Therefore the simple interest for 4 months = Rs 240
Add an x in the box djsnsjdjddjjsjsns
200.85in
This is because
25.12^2 = 631
631/π = <span>200.85
</span>
Therefore the diameter would be <span>200.85in</span>
