Hello!

For this you can find the decimal that he did not work

9/12 = 0.75

You move the decimal 2 places to the right to find the percent

He worked 75% of the year.

So 9 is 75% of 12 as well.

Hope this helps!

Consider a 25 factorial design. (a) How many factors and levels are considered in this factorial experiment
Bad White [126]

Answer:

Step-by-step explanation:

From the information given;

We are to take a look at a 2⁵ factorial design.

The factorial design consists of carrying out the design of equipment by testing it by modifying not the parameters one by one but by modifying several simultaneous parameters.

An experiment is termed to be a 2⁵ factorial experiment if in the experiment 5 factors are studied consecutively with each at two-level.

Thus, there are five factors and 2 levels in the experiment.

6a+4=61/3+4<br> I don’t know what I’m doing wrong because I keep getting 10 1/3
Vlad1618 [11]

Answer:

a = 3 7/18 or 3.388889

Step-by-step explanation:

First, you want to get the a by itself, so you would subtract 4 from the left side of the equals sign.

6a + 4 = 61 / 3 + 4

    -4                   -4

6a = 61 / 3

By doing that, they cancel each other out, so you are left with

6a = 61 / 3

Then you want to get a by itself, so you divide 6 from both sides.

6a / 6 = 61 / 3  /  6

Remember that 6 can also be written as 6/1

Remember that dividing a fraction is multiplying the reciprocal.

6a / 6 = 61 / 3  /  6 / 1

When dividing fractions remember to Skip the first fraction, Flip the second fraction, and Multiply the two fractions together.

61 / 3      x        1 / 6

skip   multiply   flip

Multiply across the top, and across the bottom.

61(1) and 3(6)

Then you get

61 / 18

So a = 61 / 18

If you want to convert that to a mixed number, it would be 3  7 / 18

If you want that in a decimal, it would be 3.388889

The hypotenuse of a 45 degrees -45 degrees -90 degrees triangle measures 10 root of 5 in.
juin [17]

Answer:

5\sqrt{10}\ in

Step-by-step explanation:

<u><em>The question is </em></u>

Find the measure of the legs

we know that

In a 45 degrees -45 degrees -90 degrees triangle, the measure of the legs are equal

Let

a ----> the measure of one leg

Applying the Pythagorean Theorem

(10\sqrt{5})^2=a^2+a^2

solve for a

500=2a^2

Divide by 2 both sides

a^2=250

a=\sqrt{250}\ in

Simplify

a=5\sqrt{10}\ in
