Answer:
1. 90 families
2. P 500
3. 30 sits
Step-by-step explanation:
The computation is shown below:
1. The number of families belong to the poor sector is
= 150 ×60%
= 90 families
2. The new amount is
= P 2,500 × 0.20
= P 500
3. The actual sits accommodated by the passengers is
= 60 sits ×50%
= 30 sits

In 1971, the average price of gasoline was $0.36 per gallon. In 2020, the average price of gasoline was $2.32 per gallon. a. What is the percent increase, rounded to the nearest whole number, in the cost of a gallon of gasoline from 1971 to 2020? b. What is the percent decrease, rounded to the nearest whole number, in the cost of a gallon of gasoline from 2020 to 1971? 2. Last year, DeKalb Middle School had 140 7 thgraders. The number of 8 thgraders was 125% of the number of 7 thgraders. How many 8 thgraders were there last year? 3. Find the balance of a savings account at the end of 4 years if the interest earned each year is 5.5%. The principal is $700.
Answer:
1. a. 544%
b. 84%
2. 175
3. $867.18
Step-by-step explanation:
1. a.2.32-0.36=1.96
1.96/0.36=5.44
5.44*100=544
b. 1.96/2.32=0.84
0.84*100=84
2. let x = # of 7th graders
let y = # of 8th graders
y is 125% of x
y=1.25x
x=140
y=1.25*140
y=175
3. A=P(1+r)^t
A=700(1+0.055)^4
A=867.18
If y varies directly as x, and y =-4 when x=8, find y when x=3
Answer: Another way of looking at it!

b) Use the total of the results to estimate the
probability of Ben of hitting the target.
Answer:
[tex]P(Hits) = 0.70[/tex]
Step-by-step explanation:
Given
[tex]Throws = 120[/tex]
[tex]Hits = 84[/tex]
[tex]Miss = 36[/tex]
See attachment for result
Required
Determine the probability of hitting the target
This calculated using:
[tex]P(Hits) = \frac{n(Hits)}{n(Throws)}\\[/tex]
[tex]P(Hits) = \frac{84}{120}[/tex]
[tex]P(Hits) = 0.70[/tex]
Hence, the probability of hitting the target is 0.70
a) 82
b) 42
c) 98
d) 70
Answer:
option d.
let the two angle of mnp be x and y
in the trapezoid NO and MP are parallel.
so the 28° = y and 42°=x(by alternate interior angle)
so the angle mnp= x+y
angle mnp=28°+42°=70°

Please do number 15 for me
Answer:
C
Step-by-step explanation:
2x -15 +3x -5 = 180
5x -20 = 180
5x = 180+20 = 200
x = 200/5 = 40
3x -5 = 3(40)-5 = 120-5 = 115
2x -15 = 2(40) - 15 = 80-15 = 65

A container is in the shape of a cuboid the cuboid is 2/3 full of water a cup holds 275 ml of water what is the greatest number of cups
Answer:
12 cups
Step-by-step explanation:
The first step is to calculate the volume of the cubiod
= 36 × 6 × 23
= 4968
= 4968/3 ×2
= 1656×2
= 3312
Therefore the greatest number of cups can be calculated as follows
= 3312/275
= 12
Hence the greatest number of cups is 12 cups

The equation h=60-4m gives the height h (in inches) of the water in a tank m minutes after it starts to drain
Answer:
40m
Step-by-step explanation:
Complete question
The equations h = 60 - 4m gives the height h (in inches) of the water in a tank m minutes after it starts to drain. How high is the water after 5 minutes.
To get the height of the water after 5minutes, we will find h at when m = 5
h = 60 -4 (5)
h = 60 - 20
h = 40m
Hence the water is 40m high after 5minutes
