Which ratio is equivalent to

Mathematics
1 answer:
Andrews [41]3 years ago
8 0

Answer:

A.) 4h : $36

Step-by-step explanation:

Why it's right: they equal the same thing

5/45 = 1/9

4/36 = 1/9

Why it's wrong: similar, but backwards

54/6 = 9

Just plain wrong:

4/50 = 2/25

63/9 = 7

What is 3 divided 76

0.0394736842 is the answer

Write   76 <span>)¯3¯¯ 
</span>
 add a 0 next to the 3 ( you will have 30) then on top of the divison bar put a "." one space over the 3 so like  
       0.
76<span>)¯30¯¯    (lol)

since 76 still cant go into the 3 add another 0 to the 30 ( so you should now have 300) and a 0 next to the "." so you have 0.0 on top.

76 goes into 300 3 times wich is with a reminder of 72. (76x 300 is 228)

write a 3 next to the 0.0 so you have 0.03

write 228 under the 300

subtract. you get 72

write the 72

since 76 cant go into 72 add a 0 to the 300. Drop the 0 to the 72 so you have 720.

I think you can figure out the rest. If not tellme and I will do the next step and you can take it from there

The number of subscribers to a streaming video service doubles each week.
Ilya [14]

Answer:

Step-by-step explanation:

This is an exponential equation that is solved by taking the natural log of both sides.  The equation is

f(x)=2^x

If we are looking for x when f(x) = 64, then

64=2^x

Take the natural log of both sides:

ln(64)=ln(2^x)

The rules of logs allows us to bring the x down in front:

ln(64)=xln(2)

Divide both sides by ln(2) to get:

\frac{ln(64)}{ln(2)}=x

Do this on your calculator to get that x = 6.

You could also have just gone right to your calculator and started raising 2 to consecutive powers starting at like 3 or 4 to eventually get that 2 to the 6th power is equal to 64, but for the basics of solving log equations, you need to know how to do this.

Hi!

I believe the answer is D , because the common denominator is 12 .

3 times 4=12
4 times 3=12
2 times 6= 12

You multiply each fraction by 12/1 .

Hope it helps and have a wonderful day !
