Answer:
Step-by-step explanation:
<u>Given:</u>
- Tickets cost $12 at the door, number of tickets d
- Tickets cost $8.50 if purchased in advance, number of tickets a
- Minimum target from tickets sold $1050
<h3>Part 1</h3>
<u>Required inequality to meet the goal:</u>
<h3>Part 2</h3>
<u>If a = 36 then minimum value of d:</u>
- 12d + 36*8.5 ≥ 1050
- 12d + 306 ≥ 1050
- 12d ≥ 1050 - 306
- 12d ≥ 744
- d ≥ 744/12
- d ≥ 62
Minimum 62 tickets must sell
The answer is 66 sorry if incorrect

Answer:
49 inches
Step-by-step explanation:
Write and solve an equation of ratios, as follows:
7 inches x
-------------- = -----------------
8 inches 56 inches
Then (8 ")x = (7 ")(56 "), and
x = 392/8 inches = 49 inches.
The actual width of the helicopter is 49 inches.
Answer:
There are approximately 171 families in the sample.
Step-by-step explanation:
Percentile meaning:
When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.
Twenty-four of the families in the sample turned on the television for 23 hours or less for the week. The 14th percentile of the data is 23 hours.
This means that 24 is 14% of the total number of families.
Approximately how many families are in the sample?
Using a rule of three.
24 - 0.14
x - 1
0.14x = 24
x = 24/0.14
x = 171.4
Rounding to the nearest integer
There are approximately 171 families in the sample.
