Answer:

k = 13.5 units

Step-by-step explanation:

Look for the similarity ratio.

Side YZ is similar to side BC because 9 is a factor of 3.

Side XZ is also similar to side AC since 12 is a factor of 4.

And the common thing between the factors is that they were both multiplied by 3.

3 × 3 = 9

4 × 3 = 12

So for the last side, which is 4.5, we have to multiply it by 3.

4.5 × 3 = 13.5

The U.S.-based motorcycle manufacturer says that it expects to build 139,000 motorcycles this year, up from 126, 000 last year

german

The formula is (new-original)/original.

(139,000 - 126,000)/126,000

= 13,000/126,000

= .103

Now, convert the decimal into a percent by moving the decimal two places to the right and including the percent sign.

.103 = 10.3%

Answer: 10.3%

In a class of 30 students, 12 are girls. One-third of the boys study history.

frosja888 [35]

The number of boys is:
30 - 12 = 18.

18 boys* (1/3)= 6 boys
There are 6 boys who study history.

6 students/ 30 students= 1/5.

1/5 of the students are boys who study history~
