Answer:
let the width be x inches
then the length would be 3x inches
perimeter of rectangle = p = 2(l+b)
100= 2(3x+x)
100= 2(4x)
100=8x
x=100/8
x=12.5 inches
thw width is 12.5 inches and length is 3*12.5=37.5 inches
Step-by-step explanation:
1) 30
2) 800
3) 500
4) 4,000
5) 9
6) 600
7) 7,000
8) 200,000
9) 2,000 * 10 = 20,000. 20,000 * 10 = 200,000.
Answer:
P = $2448.89
P ~= $2,449
He need to deposit $2,449
Step-by-step explanation:
Given:
Interest rate r= 7% = 0.07
Number of years n = 3 years
Future value that should be meet A = $3000
We need to calculate the initial investment (Principal P). Using the compound interest formula:
A = P(1+r)^n
P = A/(1+r)^n
Substituting the values of A, r, n, we have;
P = 3000/(1+0.07)^3
P = $2448.89
P ~= $2,449
Answer:
the answer is 196
Step-by-step explanation:
4x+4=60
