Answer:

it's an example related to your question

Step-by-step explanation:

Q. One number is 2 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 200, find the number

Answer:First number = x

One number = 2x

Third number = 100 + x

x + 2x + 100 + x = 200

Collect like terms

4x + 100 = 200

4x = 100

x = 25

First number = 25

One number = 50

Third number =125

Total= 200

Hope this helps.

This diagram shows a right square pyramid and some of its dimensions. What is the volume of the pyramid?
ZanzabumX [31]

Answer:

Volume of square Pyramid is 48 cubic inches.

Option A is correct option.

Step-by-step explanation:

Height of Pyramid = 4 in

Length of Base = 6 in

We need to find volume of square pyramid

The formula used is:

Volume\: of\: Square\: Pyramid=\frac{1}{3}\times A \times h

Where A is area of base and h is height.

Area\: of\: Base =(Length)^2= 6^2 = 36

Now, putting values of A = 36 and h = 5 and finding volume

Volume\: of\: Square\: Pyramid=\frac{1}{3}\times A \times h\\Volume\: of\: Square\: Pyramid=\frac{1}{3}\times 36 \times 4\\Volume\: of\: Square\: Pyramid=12 \times 4\\Volume\: of\: Square\: Pyramid=48 \: cubic\:inches

So, Volume of square Pyramid is 48 cubic inches.

Option A is correct option.

On a coordinate plane, parallelograms A B C D and E F G H are shown. Parallelogram A B C D has points (4, 2), (7, 2), (4, 6), (1
Fittoniya [83]

Answer:

The area of parallelogram ABCD is equal to the area of parallelogram EFGH.

Step-by-step explanation:

Given

Parallelogram ABCD

A = (4,2)

B = (7,2)

C =(4,6)

D = (1,6)

Parallelogram EFGH

E =(-2,2)

F = (-5,2)

G = (-6,6)

H = (-3,6)

Required

Compare the areas of both parallelograms

The area of a parallelogram is:

Area =Base * Height

So: To do this, we plot ABCD and EFGH on a grid, then we measure the base and the height of both.

See attachment 1 for ABCD

In (1), we have:

Base = 3\ units

Height = 4\ units

So, the area is:

A_1 = 3 * 4

A_1 = 12

See attachment 2 for EFGH

In (2), we have:

Base = 3\ units

Height = 4\ units

So, the area is:

A_2 = 3 * 4

A_2 = 12

<em>By comparison, they both have the same areas</em>

If 3x+13= 19, find the value of 4x +1
12345 [234]

Answer:

It would be 8

Step-by-step explanation:

It would be six because 13 plus 3 is 16 and the answer was 19 so I added 3 more and I got 19. So that made me think that the value of x is 3. :)
