If the volume of the box is 123 in3, what is the height of the box?

Answers

Answer:

cube root of 123 (approx 4.97)

Step-by-step explanation:

volume of a cube is LxWxH, and since it is a cube, all measurements are equal

The height of the box is 4.973 inch whose volume is 123 cubic inches.

It is given that the volume of a box is 123 cubic inches.

It is required to find the height of the box.

What is volume?

It is defined as a three-dimensional space enclosed by an object or thing.

We have:

Volume of a box = 123 cubic inches

Here we are assuming the box is a shape of cube.

We know that the volume of a cube:

[tex]\rm V= a^3[/tex]   where a is the side of cube

In the cube all the dimensions are same.

Now,

[tex]\rm 123 =a^3 \ \ or \\\\ a = \sqrt[3]{123}[/tex](∵ V = 123)

a = 4.973 inch

Since in the cube all the dimensions are same, therefore

The height of the cube = 4.973 in

Thus, the height of the box is 4.973 inch whose volume is 123 cubic inches.

step-1: find the sum of the polygon interior angles

=900°

step-2: find x

according to the question

113+112+123+168+99+148+x=900

The first buses to X and Y leave a bus station at 7 am
Buses to X leave every 25 minutes.
Buses to Y leave every 20 minutes.
When will the buses to X and Y next leave at the same time?

Answers

They will both leave at the same time again at 8:40

Multiples of a number are the numbers that a number can be divided by without any remainder.

The buses X and Y will leave at the same time by 8:40 am

To calculate when buses X and Y will leave at the time, we would have to find the Lowest Common Multiple of 20 and 25 minutes.

Find and list multiple until the first common multiple is found. This is the lowest common multiple.

Multiples of 20:

20, 40, 60, 80, 100, 120, 140

Multiples of 25:

25, 50, 75, 100, 125, 150

Therefore,

LCM(20, 25) = 100

The LCM is 100 minutes

Converting 100 minutes

60 minutes = 1 hour

100 minutes = ?

Cross Multiply

100 minutes x 1 hour / 60 minutes

= 1 2/3 hours.

This can be rewritten as :

= 1 hr 40 minutes

Adding this to 7am

7 am + 1 hr 40 minutes = 8 : 40am

Therefore, the buses X and Y will leave at the same time by 8:40 am

Answers

Answer:

Slope- intercept form   y = 200 x + 500

Step-by-step explanation:

Given that the equation

       200x - y + 500 = 0

where   y, the number of pairs of skates the factory has in the warehouse, and x be the number of hours

The slope-intercept form

                y = m x +C

Given equation  200x - y + 500 = 0

                          200 x + 500 =y

                       y = 200 x + 500

Slope of the equation m = 200 and y-intercept 'C' = 500

What dose 3 3/4 represent on the map? Pls help im not caught up on the algebra thing Btw 1 inch is equivalent to 12 miles on the map

Answers

Answer:

45 miles

Step-by-step explanation:

Complete Question

What does 3 3/4 inches represent on the map?

1 inch is equivalent to 12 miles on the map

From the above question, the scale on the map is given as:

1 inch = 12 miles

Hence, 3 3/4 inches = x miles

Cross Multiply

1 inch × x miles = 3 3/4 inches × 12 miles

x miles = 3 3/4 inches × 12 miles/1 inch

x miles = 15/4 × 12 miles

x miles = 45 miles

Therefore, 3 3/4 inches represents 45 miles on the map.

Answer:

Let total students be ‘X’

No of girls = (X-20)

Girls/Boys=7/5=(X-20)/20

7(20) =5(X-20)

X = 240/5

X =48
