Answer:
Step-by-step explanation:
Compare same to same, make ratios (they look like fractions) cross multiply to solve.
Small/Large
=10/15 = 2/3
2/3 = 12/m
18 = m
2/3 = AB/24
16 = AB
2/3 = 13/WZ
19.5 = WZ
Answer: 68 mph
Step-by-step explanation:
The width is 18.
step by step:
1. 2 lengths are 20 which is 20+20 that's 40.
2. 76-40= 36
3. Two widths are 36 cm.
4. so do 36÷2 and that equals 18
If the 8 parts are all exactly the same size,
then the shaded portion is 3/8 of the circle.
To change any fraction to a decimal, do the division:
(3) divided by (8) = 0.375 .
To change any decimal to a percentage,
move the decimal point two places that ==> way.
0.375 = 37.5 %
When you go to select the 2 pair to take ...
-- The first one can be any one of the 7 you own. For each if these . . .
-- The second one can be any one of the remaining 6 you own.
-- So there are (7 x 6) = <em>42 ways</em> to choose 2 pairs of jeans.
<u>But</u> . . . . .
When you finish packing the 2 pairs of jeans you chose, it doesn't
matter which one was chosen first and which one was chosen last.
The same jeans could have been chosen for the trip in two
different ways.
Although there are 42 <u>ways</u> to choose two pair, the same two pair
can be chosen in 2 different ways. So there are only 42/2 = 21
different <u>sets</u> of jeans that can end up going on vacation.
