Answer:

b

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{AB}{XY} = \frac{BC}{YZ} , substitute values

\frac{15}{10} = \frac{21}{YZ} ( cross- multiply )

15YZ = 210 ( divide both sides by 15 )

YZ = 14 → b

The length of a school bus is 12.6 meters. If 9 school buses park end to end with 2 meters between each one, what's the total le
weqwewe [10]

Answer:

129.4

Step-by-step explanation:

Calculation for what's the total length from the front of the first bus to the end of the last

First step is to multiply the given number of buses by the length of each one

Hence,

12.6 meters x 9 = 113.4 meters

Second step

Since there are 8 spaces in between we would multiply the 8 spaces by 2 meters

8 x 2 meters = 16

Now let calculate total length from the front of the first bus to the end of the last

16 + 113.4 meters =129.4

Therefore total length from the front of the first bus to the end of the last will be 129.4

Answer:

A

Step-by-step explanation:

garri49 [273]
Write a proportion first, change over original, like this:
 8      x
16   100
(I got 8 because the difference between 24 and 16 is 8 and I got 100 because percents are out of 100.)
Cross multiply 8 by 100 and you get 800.
Divide 800 by 16 and you get 50.
It changed by 50%
