I’m not rlly good at math but the answer should be 25.13
So for one 3.25x5= 16.25 then 16.25x2 = 32.50. So 40 dollars will be enough
Answer:
let he invest x part of earning at the rate of 8%
simple interest = P*T*R/100 = x*1*8/100 = 0.08x
His invest at the rate of 7.5% = 3050 - x
Again simple interest = P*T*R/100 = (3050 - x)*1*7.5/100 = 228.75 - 0.075x
N0w acc0rding to question
0.08x + 228.75 - 0.075x = 242
0.005x= 13.25
x = 2650
rehman invest 2650 at 8% per year
He invest (3050-2650) = 400 0n 7.5% per year
Step-by-step explanation:
A cube is a square shape, so both sides ( length and width) of a face would be the same.
Find the length of the side by finding the square root of the area of the face:
Length = √400 = 20 cm.
Volume is Length x Width X height.
Volume = 20 x 20 x 20 = 8,000 cm^3
