Answer:
15 feets
Step-by-step explanation:
Perimeter of a rectangle = 2(l + w)
l = Length ; w = width
Perimeter, p = 48
Length of all sides
p = 2(l + w)
48 = 2(l + 9)
48 = 2l + 18
48 - 18 = 2l
30 = 2l
l = 30/2
l = 15
Length of the sides = 15 feets
Answer:
108.505
Step-by-step explanation:
Let's talk money for just a second. Which would you rather have 20 dollars or 20.32 20dollars and 32 cents?
Isn't 20.32 bigger than 20.
You should say yes.
If that is true, then 108.505 should be larger than 108.5 not by much, but still larger.
7.5 is 30 percent of 25 because
25 divided by 10 is 2.5 times 3 is 7.5
40/50 is the ratio because the cos formula is adjacent over hypotenuse and you can reduce it to 4/5 as a fraction :)
