Answer:

718,200 boxes

Step-by-step explanation:

Given the dimension of the storage space = 300ft×200ft×30ft

Dimension of each box = 20in×18in×12in

In order to determine the number of boxes Graphic DesignWorks is able to store, we will divide the Dimension of the storage space the dimension of the box.

Number of boxes = Dimension of storage space/dimension of boxes

We need to convert the dimension of boxes from inches to feet

1inch = 0.0833ft

20inches = 20×0.0833 = 1.666ft

18inches = 18×0.0833 = 1.499ft

12inches = 12×0.0833 = 0.9996ft

Number of boxes = 300×200×30/1.666×1.499×0.9996

Number of boxes = 1800000/2.496

Number of boxes = 721,153.85boxes

Based on the value, the best estimate that is close to the gotten value will be 718,200 boxes

Can someone help me solve y 12 + y = 4x
Leviafan [203]

Answer: Y = 4x - 12

Step-by-step explanation:

Well, the reason for this is because y can be anything because there are 2 unknown terms in the equation. Thus, the answer to y can be many different answers. The one common thing that all of these answers have is that they have only 1 expression (An equation without equal sign) to solve it. This expression is the answer to y, but it can be changed judging by the answer of x. That is why you cannot determine an exact answer to y with there being many, so you have to write the expression to get y. Which you can find out by:

12 (Part) + y (Part) = 4x (Whole)

So to figure out one part do the whole minus the other part which is why 4x is our answer:

4x (Whole) - 12 (Other Part)

This is called part-whole postulate.

Hope this helps!

I have many students are represented in the data set?
nalin [4]

Answer:

a) 19 students

b) the mean 3 9/19

the median 3

the mode 3

c) the range 6

Step-by-step explanation:

The data set shows that

0 points gets 1 student,

1 point gets 1 student,

2 points get 2 students,

3 points get 6 students,

4 points get 4 students,

5 points get 3 students and

6 points get 2 students.

a) There are 1+1+2+6+4+3+2=19 students.

b) The mean is

\dfrac{1\cdot 0+1\cdot 1+2\cdot 2+6\cdot 3+4\cdot 4+3\cdot 5+2\cdot 6}{19}=\dfrac{66}{19}=3\dfrac{9}{19}.

The average score is 3 9/19 points.

The median is 10th term in the data set - 3 points (means the middle score in the data set)

The mode is 3 points (means most happened score)

c) The range of the data is 6-0=6 points.
