Answer: C = 150$

Explanation:

C = chair
T = table

C = 10% of T
C = 10/100 x T
C = 1/10 x T

And
T + 4C = 2100$
T + 4(1/10 x T) = 2100$
T + (4T/10) = 2100$
T + 2T/5 = 2100$
5T + 2T = 10500$
7T = 10500$
T = 1500$

But C = (1/10)T
=> C = 1/10 x 1500$
C = 150$

A pack of gum is in the shape of a rectangle prism with a length of 8 centimeters and width of 2 centimeters. The volume of the

victus00 [196]

Hello!

We know that the length of the pack is 8 cm, width is 2 cm, and the volume is 48 cm^3.

The formula for volume is:

V = l × w × h

We don't want to find the volume...we already have that!

But we can use the volume and the length and width to find the height.

Since we multiply the dimensions to find the volume, we'll have to do the opposite to find a dimension.

And what's the opposite of multiplication? Division!

H = V ÷ lw

Multiply the length by the width, then divide the volume by that.

H = 48 ÷ 8(2)

H = 48 ÷ 16

H = 3

We can double check by using this to find the volume.

V = 8 × 2 × 3

V = 48

This means we're right!

ANSWER:

The height of the pack of gum is 3 centimetres.

Of the following two statements , which is a good definition ? Explain . " A rectangle is a parallelogram with 4 right angles .

Vikki [24]

This is about understanding the meaning of a rectangle and parallelogram.

Option A is the correct definition.

We are given the 2 statements as;

1) A rectangle is a parallelogram with 4 right angles

2) A rectangle is a parallelogram

Let us define a rectangle and parallelogram;

- A rectangle is defined as a quadrilateral with four right angles. This means all the angles are equal. It also has 4 sides with the length of opposite sides being parallel to each other.

- A parallelogram is defined as a quadrilateral that has two pairs of parallel sides with the opposite sides of such parallelogram having equal length and the opposite angles being equal.

Option A; This is correct because the reverse statement is that; A parallelogram is a rectangle with 4 right angles, This is possible because the only condition where a parallelogram is a rectangle is when it has 4 right angles.

Option B; This is wrong because a rectangle is not a parallelogram.

Option C; This is wrong because not all parallelograms are rectangles.

Option D; This is wrong because a rectangle must have 4 right angles
