Answer:
1.6
Step-by-step explanation:
5/8 = .625
1/.625 = 1.6
.625* 1.6 = 1
We know that,
diameter is twice the radius, I.e d = 2r
Now d = 2(8)ft = 16 feet
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

For example:
1/2 + 1/3
We need to find something called the least common denominator (LCD)... It's really just the LCM of our denominators, 2 and 3.
The LCM of 2 and 3 is 6. So, our LCD 6.
We need to make this our new denominator...
Change the 1/2:
1 x 3 over 2 x 3 = 3/6
Change the 1/3:
1/2 + 1/3 = 3/6 + 2/6
Now we can do it!
(3+2)/6 = 5/6
Answer:
D
Step-by-step explanation:
When we divide the entire equation by -1/2 to get rid of the coefficient of n we get n = 16.
