Answer:
D is 117
Step-by-step explanation:
Let the measure of angle C be x
The measure of D is 9 less than twice C
Mathematically that is 2x-9
If both are supplementary, they add up to be 180
Thus;
x + 2x - 9 = 180
3x = 180 + 9
x = 189/3
x = 63
Recall;
D = 2x-9= 2(63) -9 = 126 -9 = 117
Divide the number of people selected by the total number of people.
90/500 = .18
This means that 18% of the customers were selected for the survey.
If the probability is the same on Saturday, then we can multiply the expected customers by our .18
700 x .18 = 126
126 should be selected for the survey on Saturday.
The answer to one would be 25534

Answer:
B. 23 games.
Step-by-step explanation:
Current balance: $469
Goal balance: $825.50
Profit per game: $15.50
- 825.50 - 469 = 356.50
They only need $365.50 in order to reach the goal.
- 356.50 ÷ 15.50 = 23
They need to sell 23 games, each selling for $15.50, in order to reach their goal balance, of $825.50.
- Therefore, the answer is B.
