Answer:
63.5
Step-by-step explanation:
they all form a triangle, and the formula for that is a²+b²=c²
a=96 b=wire c=72
96²+b²=72²
9216+b²=5184
-9216 -9216
b²= -4032
square root of -4032 = 63.5
Answer:
D answer to dis question is 21
Answer:
9 comedy
12 horror
Step-by-step explanation:
First, there are 360 degrees in a circle.
Comedy = 90 degrees
Action and romance = 90 degrees combined
Horror = 120 degree
Science fiction = 60 degrees
To find sci fi : 90 +90 +120 = 300 - 360 = 60 degrees
36 students took the survey.
1/4 × 36 = 9
Horror is 120 degrees out of 360 degrees or 1/3 of the circle.
1/3 × 36 = 12
Answer:
Step-by-step explanation:
- x^2+8x-7<0
- x^2 + 8x + 16 - 23 < 0
- (x + 4)^2 < 23
- |x + 4| < √23 ≈ 4.8

<u>Combination of the two intervals:</u>
Answer:
11
Step-by-step explanation:
C²=23
2C=0
C=2
Substitute C=2 in the first equation 2C=23
2C=23
C=11.5
Approximately C=11
