Answer:
Approximately 11 gallons of paintStep-by-step explanation:
First we need to calculate the Total surface area of the cylindrical tank as shown;
TSA of the tank = 2πr² + 2πrh
TSA of the tank = 2πr(r+ h) where;
r is the radius of the tank
h is the height
Given
radius = 5.5ft
height = 16ft
Get the surface area;
TSA = 2π(5.5)(5.5+ 16)
TSA = 2π(5.5)(21.5)
TSA = 2π(118.25)
TSA = 2(3.14)(118.25)
TSA = 742.61ft²
If a gallon of paint will cover 130ft^2 of surface, then the total number of paint needed will be;
Total number of paint needed = 742.61/130
Total number of paint needed = 5.7
For one coat we will need 5.7gallons of paint
For two coats we will need 2 * 5.7gallons = 11.4
Hence approximately 11 gallons of paints will be needed for the two coats

Max built a rectangular Prism and a rectangular Pyramid using beach sand. The prism and the pyramid have the same base area and the same height. The amount of sand Max used to build the Prism is how many times the amount used to build the Pyramid?
Answer:
Three times
Step-by-step explanation:
Given
Figures: Rectangular Prism and Rectangular Pyramid
Let the dimension of the prism be:
[tex]l = length[/tex]
[tex]w = width[/tex]
[tex]h = height[/tex]
Amount of sand used is the volume (V1) and it is calculated using;
[tex]V_1 = l * w * h[/tex]
[tex]V_1 = lw h[/tex]
Since the pyramid has the same base area and height as the prism, the its dimension would be:
[tex]l = length[/tex]
[tex]w = width[/tex]
[tex]h = height[/tex]
Amount of sand used is the volume (V2) and it is calculated using;
[tex]V_2 = \frac{1}{3}*(lwh)[/tex]
So, we have:
[tex]V_1 = lw h[/tex]
[tex]V_2 = \frac{1}{3}*(lwh)[/tex]
Substitute lwh for V1 in the second equation
[tex]V_2 = \frac{1}{3}V_1[/tex]
Multiply both sides by 3
[tex]3 * V_2 = \frac{1}{3}V_1 * 3[/tex]
[tex]3 * V_2 = V_1[/tex]
Reorder
[tex]V_1 = 3 * V_2[/tex]
[tex]V_1 = 3 V_2[/tex]
Hence, the amount of sand used in building the prism is three times the amount of sand used in building the pyramid
A college cafeteria pays student cashiers $540 per hour. Cashiers earn an additional
$110 per hour for each hour worked over 35 hours per week. A cashier worked 39
hours one week and 37 hours the second -week. Show and explain to the cashier how her salary
would be calculated in this two-week period?
Answer:
total hr worked = 39 + 37 = 76 hr
salary per hr = 110 $
so total salary = 110 * 76 = 8360$

Gas mileage is the number of miles you can drive on a gallon of gasoline. A test of a new car shows it can drive 370 miles on 20 gallons of gas. How far could you drive on 65 gallons of gas?
Answer:
1202.5 miles
Step-by-step explanation:
It is given that.
A test of a new car shows it can drive 370 miles on 20 gallons of gas.
We need to find how far you could drive on 65 gallons of gas.
20 gallons of gas = 370 miles
1 gallon = 18.5 miles
For 65 gallons of gas, multiply 65 and 18.5.
65 gallons = 18.5 × 65 miles
= 1202.5 miles
Hence, 1202.5 miles you could drive on 65 gallons of the gas.
A recycling center pays $0.10 per aluminum can and $0.05 per plastic bottle. The Cheerleading squad wants to raise $500. Let x represent aluminum cans and y represent plastic bottles. Use this description to answer all questions in this section.
Question:
(a) Write a linear equation that describes the problem
(b). If the cheerleading squad collects 6000 plastic bottles, how many cans will it need to collect to reach the goal?
Answer:
a. [tex]0.10x + 0.05y = 500[/tex]
b. 2000 cans
Step-by-step explanation:
We have the following:
[tex]Cost = \$0.10[/tex] per aluminum
[tex]Cost = \$0.05[/tex] per plastic bottle
[tex]Total = \$500[/tex]
Solving (a): The linear equation.
If 1 aluminum can costs $0.10,
x cans would cost $0.10x
If 1 plastic bottle costs $0.05,
y bottles would cost $0.05y
Total Cost:
[tex]Aluminum + Plastic = Total[/tex]
[tex]0.10x + 0.05y = 500[/tex]
b.
If y = 6000.
Solve for x
We have:
[tex]0.10x + 0.05y = 500[/tex]
Substitute 6000 for y
[tex]0.10x + 0.05* 6000 = 500[/tex]
[tex]0.10x + 300= 500[/tex]
Collect Like Terms
[tex]0.10x = 500 - 300[/tex]
[tex]0.10x = 200[/tex]
Solve for x
[tex]x = 200/0.10[/tex]
[tex]x = 2000[/tex]
Marcus bought a booklet of tickets to use at the amusement park. He used 50% of the tickets on rides, 13of the tickets on video games, and the rest of the tickets in the batting cage. Marcus says he used 10% of the tickets in the batting cage. Do you agree? Explain.
Given :
Marcus bought a booklet of tickets to use at the amusement park.
He used 50% of the tickets on rides, 13% of the tickets on video games, and the rest of the tickets in the batting cage.
To Find :
Marcus says he used 10% of the tickets in the batting cage.
Solution :
We know sum of all the percentage should be equal to 100.
So,
( % used on rides ) + ( % used on video game ) + ( % used in batting cage ) = 100
Let, % of ticket spend on batting cage is x.
50 + 13 + x = 100
x = 100 - ( 50 + 13 )
x = 37%
So, Marcus used 37% in batting cage.
Therefore, the statement by Marcus that he use 10% of the ticket in the cage is wrong.
No, i do not agree. To find this out, we will have to convert all of them into either decimals or percents. Let's convert these all into percents. A percent means 'out of 100', so if we add the percents all together, they should equal to 100. The rides is 50%. To convert 1/3 into a percent, divide the numerator by the denominator. You will get a decimal, so then multiply that by 100 or move the decimal two places to the right. So, 1 divided by 3 is equal to approximately 33%. Let's add 50 and 33 together. The total is 83%. So, like I said, a percent is out of 100. Subtract 83 out of 100 and you will get 17. So, the remaining percent has to be 17 percent, not 10%.
Hope it helps :)

Mmmm! I love apple cider punch this time of year, and so do all my neighbors. My recipe calls for
two quarts of apple cider, three teaspoons of cinnamon, and one pint of lemon-lime soda. This will
make enough for eight people to share. In my neighborhood, however, there are 72 people. How much
do I need of each ingredient to make enough for my whole neighborhood to share?
Answer and Step-by-step explanation:
72 people total, recipe makes for 8 people
so have to make it how many times? 72/8 = 9 times
apple cider
2 quarts * 9 = 18 quarts of apple cider
cinnamon
3 teaspoons * 9 = 27 teaspoons of cinnamon
lemon-lime soda
1 pint * 9 = 9 pints of lemon-lime soda

Given parallelogram SNOW, diagonals SO and NW intersect at D.
If SD = 9x+5 and OD = 13X - 3, find the length of SO
Answer:
The length of SO is 46 units
Step-by-step explanation:
In a parallelogram, diagonals bisect each other, which means meet each other in their mid-point
∵ SNOW is a parallelogram
∵ SO and NW are diagonals
∵ SO ∩ NW at point D
→ That means D is the mid-point of SO and NW
∴ D is the mid-point of SO and NW
∵ D is the mid-point of SO
→ That means D divide SO into two equal parts SD and DO
∴ SD = DO
∵ SD = 9x + 5
∵ DO = 13x - 3
→ Equate them
∴ 13x - 3 = 9x + 5
→ Subtract 9x from both sides
∵ 13x - 9x - 3 = 9x - 9x + 5
∴ 4x - 3 = 5
→ Add 3 to both sides
∵ 4x - 3 + 3 = 5 + 3
∴ 4x = 8
→ Divide both sides by 4
∴ x = 2
→ To find the length of SO substitute the value os x in SD and DO
∵ SO = SD + DO
∵ SD = 9(2) + 5 = 18 + 5 = 23
∵ DO = 13(2) - 3 = 26 - 3 = 23
∴ SO = 23 + 23 = 46
∴ The length of SO is 46 units

Find the mode of the following data. 56,34,45,65,67,56,45,36,92,73,92,45,56
====================================================
Explanation:
Original list = {56,34,45,65,67,56,45,36,92,73,92,45,56}
Sorted list = {34,36,45,45,45,56,56,56,65,67,73,92,92}
We see that 45 and 56 both occur three times each, and this is the most occurring or most frequent. So the mode is the set {45, 56}. It is possible to have more than one mode. It is also possible to not have a mode at all if each value in a list only occurs one time.
Answer:
its between 56 and 45 and i havent rlly done this since 5th or 6th grade so

Answer:
The original price of the item is $28.
Step-by-step explanation:
So to find the original price, we have to divide the sale price by the result of one minus the discount in percentage form.
So:
First convert 25% to a decimal, 0.25.
OP(original price) = 21 ÷ 1 - 0.25 =
1 - 0.25 = 0.75
21 ÷ 0.75 = 28.
What is the equation in slope-intercept form of a line that has a slope of −12 and a y-intercept of 6?
Answer:
y=-12+1
hopes this hwlps

Sarah says that 26 ÷ 8 equals 14 ÷ 4 because both are “3 R2.” Show her mistake using decimal division. What is 26 ÷ 8? Give your answer in decimals. 26 ÷ 8 =___. Please helpppppp
Answer: 3.25
Step-by-step explanation:
Sarah made a.mistaje when she was reducing 26 ÷ 8. It should be noted that 2 is a common factor to 26 and 8. Therefore 26÷2 = 13 and not 14 that Sarah wrote. Sarah should have written 13 ÷ 4 and not 14 ÷ 4.
26 ÷ 8 in decimal will give us 3.25
A division problem is shown below.
