Cameron created a composite figure by stacking three cubes the cubes measure 2 inches on each side what is the volume of the c

8090 [49]

Answer:

24 cubic inches.

Step-by-step explanation:

The volume of one cube = s * s * s or s^3

s = 2 inches

V = s^3

V = 2 * 2 * 2 or 2^3

V = 8 cubic inches.

The volume of 3 of them is 8*3 = 24 cubic inches.

The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width. Solv

Salsk061 [2.6K]

Answer:

(P-2l)/2 =w

Step-by-step explanation:

P = 2l + 2w

Subtract 2l from each side

P -2l = 2l-2l + 2w

P-2l = 2w

Divide by 2

(P-2l) /2 = 2w/2

(P-2l)/2 =w

A sum of money invested at the compound interest payable yearly has interest in

jeka94

Answer:

49% and 30% respectively

Step-by-step explanation:

Step one:

Given data

Principal = Rs. 4,200

Final Amount= Rs. 9282 respectively

time = 2 years and

time = 4 years

Required

The rate of interest for 2 and 4 years

Step two:

the compound interest formula is

A= P(1+r)^t

for 2 years

Substitute

$9282= 4200(1+r)^2\\\\9282/4200= (1+r)^2$

$1+r= \sqrt{\frac{9282}{ 4200} }\\\\1+r= \sqrt{2.21} \\\\1+r= 1.49\\\\r=1.49-1\\\\r= 0.49\\\\$

the rate is 49%

For 4 years we have

$9282= 4200(1+r)^4\\\\9282/4200= (1+r)^4$

$1+r= \sqrt[4]{\frac{9282}{4500} } \\\\1+r=\sqrt[4]{2.21} \\\\1+r= 1.30\\\\r=1.30-1\\\\r= 0.30\\\\$

the rate is 30%
