Using a calculator, work out:
V2704 * 2^2– V49

Answers

Answer:

201

Step-by-step explanation:

The computation is shown below:

Given that

[tex]= \sqrt{2704} \times 2^2 - \sqrt{49}[/tex]

= 52 × 4 - 7

= 208 - 7

= 201

Here we assume that V denotes the square so according to this we solve the given situation

After solving this, the answer is 201

A module house is made by sticking a triangular prism on top of a rectangular block, as shown in the diagram.

Answers

Answer:

d

Step-by-step explanation:

The volume of the triangular prism.

= Base area x length of the prism

The volume of the rectangular block.

= Length x width x height

The volume of the model house is 1260 cubic feet.

Option A is the correct answer.

What is a rectangle?

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Module house:

Triangular prism on top and a rectangular block.

The volume of the triangular prism.

= Base area x length of the prism

= (1/2 x 12 x 4) x 15

= 24 x 15

= 360 cubic feet

The volume of the rectangular block.

= Length x width x height

= 12 x 15 x 5

= 900 cubic feet

The volume of the block house.

= Volume of the triangular prism + Volume of the rectangular block

= 360 + 900

= 1260 cubic feet

Thus,

The volume of the model house is 1260 cubic feet.

Option A is the correct answer.

Which ratio is not equivalent to the other three? A 2 3 B 12 15 C 18 27 D 6 9

Answers

Answer: B= 12 15

Step-by-step explanation:

The given ratios are

A) 2 3= 2: 3  already in its simplest form

B)  12 15 =12:15 Changing to its simplest form, we divide both by 3 giving us           4:5

C)  18 27 =18: 27  Changing to its simplest form, we divide both numbers by 9 giving us =2:3        

D)6 9=6:9  Changing to its simplest form, we divide both by 3 giving us  

       2:3

Therefore the ratio not equivalent to other three is 12:15
