<h3>Answer:</h3>

5

<h3>Solution:</h3>
  • First, n*7 can be written as 7n.
  • Then, 7*5 is equivalent to 35.
  • So we have
  • 7n=35
  • In order to find the value of n, we need to divide both sides by 7:
  • n=5

Hope it helps.

The volume of a rectangular prism is 75 cubic inches. The height is 3 inches.
mylen [45]

Answer:

A) 5 in. long and 5 in. wide

Step-by-step explanation:

Given:

Volume of a rectangular prism = 75 cubic inches

Height of prism = 3 inches

Volume of a rectangular prism is given by = l\times w\times h

where l representslength of base, w represents width of base and h represents height of the prism.

We will check the choices given by finding the volume for the given dimensions of length and width while height remains the same and see if it matches with the given volume of the prism.

A) l=5\ in w=5\ in

Volume of prism = 5\times 5\times 3=75\ in^3

B) l=10\ in w=2\ in

Volume of prism = 10\times 2\times 3=60\ in^3

C) l=5\ in w=4\ in

Volume of prism = 5\times 4\times 3=60\ in^3

D) l=15\ in w=5\ in

Volume of prism = 15\times 5\times 3=225\ in^3

So, we see that the dimensions given in option A would give the volume of prism = 75 cubic inches.

Is 3pi/2pi a rational number or an irrational number? Explain your reasoning
Vadim26 [7]

Answer:

It is rational

Step-by-step explanation:

The pi terms cancel out when you divide. This is due to the rule x/x = 1 where x is any number you want except x cannot be zero. So replace x with pi and we have pi/pi = 1

Therefore,

(3pi)/(2pi) = (3/2)*(pi/pi)

(3pi)/(2pi) = (3/2)*1 .... use the rule mentioned above

(3pi)/(2pi) = 3/2

we get a fraction or a ratio of two whole numbers, so this proves that the given expression is rational.

The data set below shows the number of cars parked in the restaurant parking lot during the lunch hour each day for two weeks: 8
just olya [345]
The first steps would be to put the numbers in order:
7, 7, 8, 9, 9, 10, 10, 11, 12, 13, 14, 14, 27

Now you can see the outlier(s) which would be 27.

Now that you know your one outlier that eliminates two of the answers so your options are either A or C.

Since the outlier is a bigger number, the answer is:

C. <span>There is one outlier that indicates an unusually large number of cars were in the parking lot that day.</span>


Good Luck!&#10;
Hope This Helps :)
