i know the answer for question 8 & 9

8) Volume is the amount of space a 3D shape takes up.

A cubic cm block takes up 1 cubic cm. This is written as 1 cm³.

You can work out the volume of a shape by multiplying height × width × depth.

If the shape is made of cubic cm blocks, you can count the cubes to find the shape's volume.

9) The face or surface of a solid on its sides. That is, any face or surface that is not a base. See also. Lateral surface area, prism, pyramid, cone, cylinder.

A $300 tablet is on sale for $234. what is the percent of discount ?

Answers

I like to think of these like this.

What was the amount of the discount? 300 - 234 = $66 dollars.

66 is to 300 as ? is to 100?

This is how that question looks in an equation:

66/300 = x/100 Solve for x by cross multipying.

66 x 100 = 300 x

660 = 300 x

x = 22

The discount amount on the tablet is 22% off the regular price.

Check it!

300 x .22 = $66 dollars off. 300 - 234 = $66 off.

Yes! It checks.



The sum of two numbers is 92. their difference is 20. find the 2 numbers

Answers

The two numbers in question obtained by creating a system of equations are 56 and 36

Let the two numbers be : a and b

  • a + b = 92 ___(1)
  • a - b = 20.___(2)

From (2):

  • a = 20 + b. ____(3)

Substitute (3) into (1)

a + b = 92

20 + b + b = 92

20 + 2b = 92

2b = 92 - 20

2b = 72

b = 72/2

b = 36

From (3) :

a = 20 + 36

a = 56

Therefore, the two numbers are 56 and 36
