The edge of a cube measures 3.5 x 10 ^ -2 meters. What is the volume of the cube in cubic meters? WRITE Your ANSWERS IN SCIENTIF
Crank

The volume of given cube is: 4.29 * 10^{-5} cubic meters

Step-by-step explanation:

Volume of a cube is given by:

V = a^3

Given

Edge of the cube = 3.5*10^{-2}

Putting the value of edge

V = (3.5*10^{-2})^3\\V = 42.875 * (10^{-2})^3\\V = 42.9 * 10 ^{-2*3}\\V = 42.9 * 10^{-6}\\V = 4.29 * 10 * 10 ^{-6}\\V = 4.29 * 10^{-5}\ cubic\ meters

The volume of given cube is: 4.29 * 10^{-5} cubic meters

Let a represent the number of ounces of perfume A. Let b represent the number of ounces of perfume B. Perfume A costs $11 per ou
Julli [10]

Answer:

The system of equations in standard form is equal to

11a+19b=71

a+b=5

The number of ounces of perfume A is 3\ ounces

The number of ounces of perfume B is 2\ ounces

Step-by-step explanation:

Let

a-----> the number of ounces of perfume A

b----> the number of ounces of perfume B

we know that

11a+19b=71 -----> equation A

a+b=5

a=5-b -----> equation B

substitute equation B in equation A and solve for b

11(5-b)+19b=71

55-11b+19b=71

8b=71-55

8b=16

b=2\ ounces

Find the value of a

a=5-b -----> a=5-2=3\ ounces
