Determine the scale of dilation

First, we pick a side on ABC

AB = 6

Pick a corresponding side on DEF

DE = 3

The scale factor is then calculated as:

Scale\ Factor = \frac{DE}{AB}

Scale\ Factor = \frac{1}{2}

i.e. ABC was dilated by 1/2

How many 6-digit numbers can be created using8, 0, 1, 3, 7, and 5 if each number is used only once?
Ludmilka [50]

Answer:

600 numbers

Step-by-step explanation:

For six-digit numbers, we need to use all digits 8,0,1,3,7,5 each once.

However, 0 cannot be used as the first digit, because it would make a 5-digit number.

Therefore

there are 5 choices for the first digit (exclude 0)

there are 5 choices for the first digit (include 0)

there are 4 choices for the first digit

there are 3 choices for the first digit

there are 2 choices for the first digit

there are 1 choices for the first digit

for a total of 5*5*4*3*2*1 = 600 numbers

A right square prism has a volume of 75 cubic inches. The prism is enlarged so its height is increased by a factor of 5, but the
kvasek [131]

Answer:

The new volume is 375 cubic inches.

Step-by-step explanation:

Volume of a right square prism:

The volume of a right square prism is given by:

V = a^2h

In which a is the length of the edge and h is the height.

A right square prism has a volume of 75 cubic inches.

This means that:

a^2h = 75

The prism is enlarged so its height is increased by a factor of 5

Edge is the same, height is 5 times. So

a^2(5h) = 5(a^2h) = 5*75 = 375

The new volume is 375 cubic inches.
