Like earlier take the bigger shape and divide the smaller one.
8.4 divide by 4 and you get 2.1.

a) Scale factor is = Second Value / First Value
= 8.4 / 4 = 2.1

b) 0.25 = Second Value / First value

0.25 = Second Value / 9

Second value = 0.25 * 9 = 2.25.

An employee earned $56,700.00 in a year and had $8,788.50 withheld for federal income tax. What federal income tax percent was withheld? if necessary, round your answer to the nearest hundredth of a percent. (Hind: write out a verbal sentence of what you are trying to find, then turn into a mathematical equestion to solve)Show your setup as well as answer.

Answers

so earned 56,700 in a year and had 8,788.5 held back
convert to percent

so find what percent was withhelald which is (amount held back)/(total taken from)
so it would be 8,788.5/56,700=0.155/1
percent means parts out of 100 or x/100=x% so convert the bottom number ot 100 by mulitplyint the whole fraction by 1 or 100/100 so
0.155/1 times 100/100=15.5/100=15.5%
the answer is 15.5%

30 POINTS The graph shows how many inches above the ground, y, the valve on a rotating tire is for a given number of seconds x.

How many degrees is the tire turning every second?

Enter your answer in the box.

Answers

Answer:

180 degrees per second.

Step-by-step explanation:

We have been given a graph that shows the distance covered by a tire or angular velocity of a tire with respect to the number of seconds (x).

Since we know that a tire is a circle and the measure of all the angles of a circle equals to 360 degrees.

We can see from our given graph that the tire completes one rotation in 2 seconds (2.5-0.5), so the distance covered by tire in two seconds will be 360 degrees. This means that the tire turns 360 degrees in each 2 seconds.

$\text{Degrees turned by tire in 2 seconds}=\frac{360^o}{2\text{ seconds}}$

As we are asked to find the degree change by tire per second so we will find the unit rate such that we will have 1 in our denominator. By dividing our numerator and denominator by 2 we will get,

$\text{Degrees turned by tire in every second}=\frac{180^o}{\text{ second}}$

Therefore, the tire is turning 180 degrees per second.

It takes 2 seconds for the tire to make a full revolution. This is evident from the plot - the curve has a period of length 2.

A full revolution of the tire is a turn of 360 degrees.

So the tire turns at a rate of (360 degrees)/(2 seconds) = 180 degrees/second.

What is this answer?Mark drew the following model and said it represented 21÷4 what is 21÷4?

Answers

$\sqrt[4]{21}$

4 goes into 21 five times, because 4 * 5 = 20

$21 - 20 = 1$

21 ÷ 4 = 5 r 1

The answer is 5.25 20/4=5. 1/4=25
