Answer:
approximately 54.7% did not respond.
Step-by-step explanation:
Consider the provided information.
The college chooses 150 businesses at random from telephone listings.
Of these, 68 return the questionnaire.
That means 68 of them responded.
The number of people who did not respond are:
150-68=82
The number of people who did not respond are 82.
Now find the percentage of people who did not respond.

Hence, approximately 54.7% did not respond.
Answer:
x=12
Step by step explanation:
Step by step explanation:Add 9 to both sides :
15 = 2x - 9
15 + 9 = 2x - 9 + 9
Simplify:
24 = 2x
Divide both sides to get the result:
24 = 2x
24/2 = (2x)/2
Result:
x=12


Answer:
8 cm
Step-by-step explanation:
(See the image attached for details)
- The blue segment measures 15 cm
- The green segment measures 7 cm
- The green and yellow segment when added form the blue segment
- So: ? + 7 = 15
Solve:
? + 7 = 15
Subtract 7 on both sides:
? + 7 = 15
-7 -7
? = 8 cm
Therefore, the yellow segment, or the missing side length, measures 8 cm.
