Answer:
14.7 mi
Step-by-step explanation:
This can be solved with the Pythagorean Theorem. This represents a triangle where the length of a is 13, b is 7, and c is unknown.
We know that , and we can plug in what we know and use algebra to solve for c.
,
169 + 49 = c^2
218 = c^2, c^2 = 218
√c^2 = √218, or c = 14.7. The length from his home to his place of work is 14.7 mi
Answer:
$46.15
Step-by-step explanation:
Answer:
12.5%
Step-by-step explanation:
There are two types of spinners here and the outcome of them is independent. That means
P(odd number,C) = P(odd number) * P(C)
There are two odd numbers out of four numbers in the first spinner. The chance of odd number will be:
P(odd) = 2/(2+2)= 1/2= 50%
There are four letters and the desired outcome is C. The chance for C will be:
P(C)= 1/4= 25%
Then the chance will be:
P(odd number,C) = P(odd number) * P(C)
P(odd number,C) =50% * 25% = 12.5%
