Answer:

9

Step-by-step explanation:

since they're similair then similair sides will be proportional

CB is similair to EF

\frac{6}{8}= \frac{3}{4}

same thing if you try with the hypotenuse AB similair to DE

\frac{13.5}{18}= \frac{3}{4}

So, if you multiply  r (DF) by 3/4  you will get the similair side AC

rx 3/4=12

r= 12÷ 3/4

r=16

6. Blake went to the grocery store at 6:30PM, He returned to his house around 9:14PM after running
zhenek [66]
If you subtract the times periods form each you will be able to get your answer. So, 9:14-6:30 it will be 2 hours and 44 mins because from 6:30 to 7 it 30 mins, and from 7 to 9 it’s 2 hours. So far, add the two and you get 2h and 30mins and from 9 to 9:14 it’s 14 mins. So, 2h 30 mins plus 14 mins is 2h and 44mins.

7th grade math. answer ASAP. If you answer correctly i will give thx, 5 star, and brainliest
Viktor [21]
Okay. First thngs first, let's divide each of them. 2.6/1.3 is 2. Now in terms of exponents, we would just simply subtract the powers, because we are doing division. 9 - 2 is 7. The value of the expression is 2 * 10^7. Even writing the problem out in number form (2,600,000,000/130), you can still see the answer to the problem as 20 million. The answer is B.
