Answer:

All three statements are true

Step-by-step explanation:

A shipping fee of 5% is charged online with every item purchased online

First let's just take each option and calculate them based on this, to see if the answers matched

Keith buys a 40 dollar book

40 x 0.05 = 2

Therefore there will be a two dollar fee on Keith's book

40 + 2 =42

The first statement is true

A chair costs $80

80 x 0.05 = 4

80 + 4 = 84

The second statement is true

George buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

The third statements are true


All three statements are true

Liam has bought 48 feet of fencing that he will use to build a pig pen. List 6 different dimensions he could create for his pen
Reptile [31]
I assume, that this pen is rectangular. 

Look, that  48 = 24 * 2 = 12 * 2 * 2 = 3 * 2 * 2 * 2 * 2
And know choose these numbers and multiply! 

First dimension:  3*2 x 2*2*2 = 6 x 8
Second:   3 x 2*2*2*2 = 3 x 16
Third: 3*2*2 x 2*2 = 12 x 4
Fourth: 3*2*2*2 x 2 = 24 x 2
Fifth: 48 x 1
Sixth dimension cannot be integer. So you can for example save this  as
48 = 3 * 16 = 1.5 * 2 * 16 = 1.5 * 32

Sixth dimension:  1.5  x  32

NOTE: each dimensions are in feet!

What is the slope intercept form of y= -2

We have y = -2. It's the slope intercept form where m = 0 and b = -2.

y = -2 → y = 0x - 2

Answer:

always true

Step-by-step explanation:

complement equals that angle plus another one adds to 90. If you know that it's less than 90 degrees, then you subtract it from 90 to get the other angle which is the complement. Hope this helps!
