Shaquil needs to borrow $400. The loan company charges him $80 in fees for the loan. Shaquil calculates that the annual percenta

lesya [120]

Answer:

(B)

Step-by-step explanation:

PRINCIPAL AMOUNT(p) = $400

RATE (r)= 250% = 2.5

INTEREST = $80

t = time (in days) = t/365

By using the formula,

r = $\frac{i}{pt}$

2.5 = $\frac{80*365}{400*t}$

t = $\frac{364*80}{400*2.5}$

t = 29.2

t = 29 days (approx)

Hence option (B) is correct.

Write the equations:
S=L/4
L-S=36
Plug the first one in the second one:
L-L/4=36
3L/4=36
L=48
Then S=L/4=48/4=12

Each side of a square is lengthened by 2 inches. the area of the new, larger square is 121 square inches. find the length of a s

tiny-mole [99]

Let the original side length be x. Then (x+2)^(in)^2 = 121 sq in.

Thus, x^2 + 4x + 4 = 121;
x^2 + 4x - 117 = 0 = (x-13)(x+9) = 0. Then x = 13 and x = -9.

We need to discard the negative result (-9).

The side of the original square is 9 inches. (answer)

Check: does (9+2)^2 = 121? Does 11^2 = 121? YES.
