Answer:
5:9
Step-by-step explanation:
20÷4=5
36÷4=9
If you divide 20 by 4 you get 5. If you divide 36 by 4 you get 9. You need to be able to divide each number in the ratio by the same number. In this case, that number is 4. You can tell that this ratio (5:9) is in simplest form because 5 is a prime number and cannot be simplified any more.
If you want to check this divide the ratio by 2 two times. Or just divide it by 4 once.
20÷2=10 → 10÷2=5
36÷2=18 → 18÷2=9
Answer:
1 x 3 x 1 = 3
Step-by-step explanation:
By definition, the perimeter of a rectangle is given by:
P = 2W + 2L
Where,
W: width
L: length
Substituting we have:
930 = 2W + 2 (3W-75)
Rewriting we have:
930 = 2W + 6W - 150
930 + 150 = 8W
1080 = 8W
Clearing W:
W = 1080/8
W = 135 feet
The length will be:
L = 3W-75 = 3 * (135) -75
L = 330 feet
Answer:
the dimensions of the base are:
W = 135 feet
L = 330 feet
