The ratio of the volume of two solids is 1331:729. What is the ratio of the surface area

1 answer:

8 0

Volume ratio = 1331/729 which is the cube of the linear scale factor.
To find the linear scale factor, let find the cubic root of the numerator & the denominator:

∛1331 = ∛11³ = 11

& ∛729 = ∛9³ = 9

So the linear scale is 11/9 ==> then the ratio of their surface area will be:

11²/9² ==> 121/81.
Note, if you have a linear scale, then the surface will be the square othis scale & the volume will be the cube of the linear scale

Olenka [21]

Answer:

4x + 5 = 101

Step-by-step explanation:

Step 1: Determine how much money both have

Aylen: x

Rich: 5 + 3x

Step 2: Write an equation and solve

Aylen + Rich = 101

x + 5 + 3x = 101

Step 3: Solve the equation

x + 5 + 3x = 101

4x = 96

x = 24

Step 4: Determine how much money does Aylan and Rich have

Aylan has $24

Rich has 5 + 3(24) = $77

Which function models the area of a rectangle with side lengths of 2x – 4 units and x + 1 units? What is the area when x = 3?

Bingel [31]

Answer:

Step-by-step explanation:

Length = 2x-4

Width = x+1

Let x=3 and find the length and width

Length = 2*3-4 = 6-4 =2

Width = x+1= 3+1 =4

The area is given by

A = l*w = 2*4 = 8
