By definition, we have to

 W = V * Dw

 W: weight

 V: Volume

 D: Density

 Clearing and Substituting we have:

 V = W / Dw = (3.2 lb) / (0.021 (lb / in ^ 3)) = 152.38 in ^ 3

 Then, on the other hand, the volume is

 V = l * w * d

 l: long

 w: width

 d: depth

 Clearing and substituting

 l = V / (w * d) = (152.38 in ^ 3) / ((1.5 in) * (5.5 in)) = 18.5 in

 The answer is 18.5 in

From the slope our equation so far is

Tanya made 75 flyers for five volunteers in her club to hang up around her school she gave 15 flyers to the first volunteer 22 f
AysviL [449]

Answer:

The remaining volunteers would get 11 flyers each.

Step-by-step explanation:

Given:

Total number of flyers = 75

Total number of volunteers = 5

Number of flyers for 1 volunteer = 15 flyers.

Number of flyers to 2nd volunteer = 22 flyers.

number of flyers to 3 volunteer = 16 flyers.

We need to find the remaining number of which are equally distributed in remaining number of volunteers.

Solution:

First we will find the number of flyers already distributed.

number of flyers already distributed is equal to sum of Number of flyers for 1 volunteer, Number of flyers for 2 volunteer and Number of flyers for 3 volunteer.

framing in equation form;

number of flyers already distributed = 15+22+16 = 53\ flyers

Number f flyers remaining is equal to Total number of flyers minus number of flyers already distributed.

Number of flyers remaining = 75-53= 22\ flyers

Number of volunteers remaining  =2

Now we will find number of flyers remaining each volunteers would get.

number of flyers remaining each volunteers would get is equal to Number of flyers remaining divided by Number of volunteers remaining.

framing in equation form we get;

number of flyers remaining each volunteers would get = \frac{22}{2}=11\ flyers

Hence the remaining volunteers would get 11 flyers each.
