Answer:
27
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(48+x) * 48 = 60^2
(48+x)48=3600
Divide each side by 48
48+x =75
Subtract 48
48+x-48 = 75-48
x =27
Remark: in the solution, the word Combination is used in the daily usage of the word, not in the combinatorial (mathematical) language.
Let the available 4 base colors be

,
the available 6 accent colors be

,
and the available 2 fonts for the embroidery be

,
so we have 4 b's, 6a's and 2 e's.
The event that Ray and Lilly design identical shoes can happen in the following way:
Ray has in total 4*6*2=48 possible combinations, and in each of these combinations, Lilly makes the same exact combinations of the 3- b's, a's and e's.
The sample space is 48 possible combinations of Ray * 48 possible combinations of Lilly = 48*48
(among these there are 48 matches of the combinations)
Thus P(designing identical shoes)=48/(48*48)=1/48=0.02
Answer:0.02
Answer: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
Answer:
5 is a constant
2 is a coefficient
7a + 5 + 2b is written as a sum of three terms
