A rectangular box has faces with areas of 12,15, and 20 square units. What is the volume of the box?

1 answer:

6 0

First find the side lengths of the box by factoring each area:

12: 1, 2, 3, 4, 6, 12
15: 1, 3, 5, 15
20: 1, 2, 4, 5, 10, 20

Find 3 numbers that both have 2 sides have in common and can multiply to make the areas of the faces:

12: 3 * 4
15: 3 * 5
20: 4 * 5

Sides: 3, 4, and 5

Then multiply to get the volume:

3 * 4 * 5 = 60 units^2

The sides of triangle can be represented by x+3, 2x+4 and 3x-1. what would be the perimeter of it were scaled down by half

svlad2 [7]

The perimeter will also be scaled down by half if the original triangle if it were scaled down by half.

<h3>What is the perimeter of a triangle?</h3>

The total length of a triangle's boundary is referred to as its perimeter. It is the total of the triangle's three sides. A triangle's perimeter will be equal to a+b+c if its three sides are a, b, and c.

The sides of the original triangle are:

x+3, 2x+4, 3x-1

The perimeter of the triangle will be

$x+3+2x+4+3x-1\\=6x+6$

If it were scaled down by half then new sides will be

$\frac{x+3}{2} , \frac{2x+4}{2} , \frac{x-1}{2}$

So, the perimeter of the new triangle will be

$\frac{x+3}{2} + \frac{2x+4}{2} + \frac{3x-1}{2}\\=\frac{x+3+2x+4+3x-1}{2} \\=\frac{6x+6}{2}\\ =3x+3$

This is half of the original triangle's perimeter. Therefore, the perimeter of the new triangle is half of the perimeter of the original triangle.

A large firm that owns a chain of grocery stores wanted to see if they could increase the average number of patrons who visit by

mote1985 [20]

Answer:

a. use a computer program to select the locations have a rewards program and those that don't.

Step-by-step explanation:

Randomization refers to an important statistical procedure used to eliminate bias in a study. With randomization, all subjects in the study possess equal chances of being selected. In the study scenario described above, randomly choosing half of their total location to partake in the reward program would involve the use of a technique which isn't liable of introducing bias into the study either deliberately or systematically. The use of store managers or other human in the selection process won't be totally convincing at preventing bias. Hence, a computer program will do.
