**Answer:**

the additive inverse is 8/17

**Answer:**

The asnwer is 12100 cm^2 of plastic without lid

**Step-by-step explanation:**

There 6 sides in a box, but there is no lid so only 5 sides.

Calulate the area of all 5 sides and add them up.

( ( 50 x 30) x 2 ) +( ( 70 x 50 ) x 2) + ( 70 x 30 )

=12100 cm^2

**Answer:**

see below

**Step-by-step explanation:**

The volume of a cylinder is given by

V = pi r^2 h

We know the radius is 9 and the height is 20

V = pi ( 9)^2 ( 20)

V = 1620 pi

If we approximate pi by 3.14

V =5086.80 cm^3

If we approximate pi by pi button

V =5089.3800099 cm^3

Answer:

8

Step-by-step explanation:

the formula for direct variation =

**Y ∝ kX**

such that

Y = kX

from the question we have here

Y = Volume = 24

x = height = 3

when we put this in the formula above in bold

24 ∝ 3k

24 = 3k

from here we have to find the value of k. to do this, we divide through by 3

24/3 = 3k/3

8 = k

**therefore the value of k is 8**

**Answer:**

z = 3/2

**Step-by-step explanation:**

0 = |2z - 3|

|2z - 3| = 0

2z - 3 = 0 or -(2z - 3) = 0

2z = 3 or -2z + 3 = 0

z = 3/2 or -2z = -3

z = 3/2 or z = 3/2

z = 3/2
