What is the value of N in this proportion 16/40= 8/n

Eduardwww [97]

Answer:

n = 20

Step-by-step explanation:

$\frac{16}{40} = \frac{8}{n}$

Cross multiplication would result in:

16 * n = 8 * 40

16n = 320

n = 320 / 16

n = 20

Therefore the value of "n" in this proportion is 20.

Hope this helps!

PLZ HELP NEED THIS ASAP!!!!! Which of the following items are required when making a line graph? Select all that apply.

zhuklara [117]

I believe A, D, and E are the correct answers.

I don't think the title of a line graph is completely necessary, as long as the viewers know what the graph is showing.

Also, color is not important if you only have 1 line. If you have multiple lines though, then you would probably need color.

But it is extremely necessary to have equal intervals on your graph, otherwise it just won't make sense.

Also, if you don't have an X axis or a Y axis, then half of your graph is missing!

I'm not sure if it's as necessary to have a grid, but the graph might be hard to read without it. So, I would put that down as an answer.

Answer:

x = 3

Step-by-step explanation:

exponential equation:

nb=a

logarithmic equation: logna=b

If you put in 8 for f(x) your exponential equation is

2x=8

Use the pattern above to change it to a log equation

8 = 2^x

log 8 = log 2^x = xlog 2

log 2^3 = 3log 2 = xlog 2

x = 3

Doug earns $10.50 per hour working at a restaurant. On

alexira [117]

First, add all of the working hours.
1 $\frac{3}{4}$ + 2 $\frac{1}{3}$ + 1 $\frac{5}{12}$

Since the denominators are different, make them all the same.
1 $\frac{9}{12}$ + 2 $\frac{4}{12}$ + 1 $\frac{5}{12}$

Add everything together.
4 $\frac{1}{12}$ + 1 $\frac{5}{12}$ = 5 $\frac{6}{12}$

Then, simplify.
5 $\frac{1}{2}$ or 5.5

Multiply the time by the salary.
5.5*10.5= Doug earned $57.75
