Answer:

Total square inches glass need = 432 inch square

Meter square paint need = 36.5 meter square

Step-by-step explanation:

Given:

Length of rectangular window = 24 inch

Width of rectangular window = 18 inch

Length of parallelogram = 7.3 meter

Height of parallelogram = 5 meter

Find:

1. Total square inches glass need

2. Meter square paint need

Computation:

Total square inches glass need = Area of rectangle window

Area of rectangle window = l x b

Area of rectangle window = 24 x 18

Area of rectangle window = 432 inch square

Total square inches glass need = 432 inch square

Meter square paint need = Area of parallelogram

Area of parallelogram = Base x Height

Area of parallelogram = 7.3 x 5

Area of parallelogram = 36.5 meter square

Meter square paint need = 36.5 meter square

Elina [12.6K]

Answer:

b. 9.2 minutes

Step-by-step explanation:

To find the expected waiting time for a random call from the sampie given by using the formula:

\sum (f(X)) = \dfrac{\sum f (x) \times x}{\sum x}

number of calls (x)           waiting time f(x) in minutes         f(x) *(x)

0                                                     0                                         0            

2                                                     3                                         6

4                                                     10                                       40

6                                                     15                                       90  

8                                                     10                                       80

10                                                     6                                       60  

\sum x = 30                                                                          \sum f(x) *x = 276

Therefore:

\sum (f(X)) = \dfrac{276}{30}

\sum (f(X)) = 9.2

Consider this cube with a volume of 64 cubic centimeters.
Eduardwww [97]

Answer:

This is a perfect cube.

The side length is 4.

Taking the cube root of the volume will determine the side length.

Step-by-step explanation:

We are told that:

A cube has volume 64 centimeters cubed.

The formula for the volume of a cube = s³

Where s = side length

Hence

64 cm³ = s³

We can find s by finding the cube root of both sides

Hence,

cube root(64) = cube root(s³)

s = 4 cm

Note that 64 is a perfect cube because 4 × 4 × 4 = 4³ = 64 cm³

Therefore, it can be concluded of the cube that:

This is a perfect cube.

The side length is 4.

Taking the cube root of the volume will determine the side length.
