Answer:
The pool that they buy is the circular pool which Marsha wants
The cost of the circular pool is $471.25
Step-by-step explanation:
The parameters of the swimming pools which each of Pete and Marsha wants to buy is given as follows;
The dimensions of the pool Pete wants = 18 feet wide, 20 feet long and 6 feet deep
The dimensions of the circle shaped pool Marsha wants = 20 feet across and 6 feet deep
The price of water, P = 25 cents per cubic foot
The pool they decide to buy = The pool that costs less to fill
The volume of water to fill the pool Pete wants, V₁ = 18 ft. × 20 ft. × 6 ft. = 2,160 ft.³
The cost of filling the pool Pete wants, C₁ = V₁ × P
∴ C₁ = 2,160 ft.³ × 25cents/ft.³ = 54,000 cents = 540 Dollars
The volume of water to fill the pool Marsha wants, V₂ = π·(20 ft.)²/4 × 6 ft. ≈ 1,884.96 ft.³
The cost of filling the pool Marsha wants, C₁ = V₁ × P
∴ C₁ ≈ 1,884.96 ft.³ × 25 cents/ft.³ ≈ 47,124 cents = 471.24 Dollars
The pool that they buy is the circular pool that Marsha wants and it costs $471.24 to fill
Work out the volume of the cone, giving your answer
to 3 significant figures.
Answer:
V = 1010 sq cm. to 3 significant figures
Step-by-step explanation:
V = [tex]\frac{1}{3} pi 8^{2} (15)[/tex]
= [tex]\frac{\pi 64(15)}{3}[/tex]
= 1005.309649,,,

A ticket to the state fair cost $15. The equation y=15x relates the total cost of tickets (y) to the number of tickets purchased (x). Identify the unit rate in the equation.
Answer:
15
.
Step-by-step explanation:
Ticket cost = $15
Cost equation :
y = 15x
x = number of tickets purchased
y = total cost of x tickets
The unit rate in the equation is the Coefficient of x ; which is the sales price of one ticket.
Hence, the unit rate is $15

During a sprint, a basketball player is traveling at +3 m/s. Four seconds later, the player is traveling at –5 m/s. The average acceleration of the basketball player over the last 4 seconds is:
Answer:
the average acceleration of the basketball player over the last 4 seconds is 0.5 m/sec^2
Step-by-step explanation:
The computation of the average acceleration is shown below:
= Change in velocity ÷ change in time
= 5 - 3 ÷ 4
= 2 ÷ 4
= 0.5 m/sec ^2
Hence, the average acceleration of the basketball player over the last 4 seconds is 0.5 m/sec^2

1/4 of 6 feet is how many inches
Answer:
18 inches
Step-by-step explanation:
1 ft = 12 in
6 ft = ? in
Set up an equation to convert 6 feet into inches
Variable x = number of inches
1 ft/12 in = 6ft/x in
Cross multiply (feel free to ignore units for now so it doesn't get in the way of your calculations)
1 × x = 12 × 6
1x = 72
x = 72 inches
6 feet = 72 inches so replace 6 feet with 72 inches
Now let's find 1/4 of 72 inches
Set up another equation to solve
Variable y = a fourth of seventy two inches
1/4 = y/72
Cross multiply
1 × 72 = 4 × y
72 = 4y
Divide both sides by 4 to isolate variable y
72 ÷ 4 = 4y ÷ 4
18 = 1y
18 = y
Answer:
I know I already said this but
18 inches

Answer:
[tex]b = l\times w[/tex] to guarantee that both formulas are the same.
Step-by-step explanation:
Dimensionally speaking, the volume is the cube of length. By direct comparison, we find that [tex]l,w,h[/tex] have length units, whereas [tex]b[/tex] have area unit, that is, the square of length.
Hence, [tex]b = l\times w[/tex] to guarantee that both formulas are the same.
If BE=9cm, find GE
What is the answer
Answer:
GE = 3 cm
Step-by-step explanation:
BE = 9 cm
Since G is the centroid, therefore:
[tex] GE = \frac{1}{3}(BE) [/tex] => Centroid theorem
Plug in the value
[tex] GE = \frac{1}{3}(9) [/tex]
GE = 3 cm

The population of a town was 489 in 1970. The population has been growing at a rate of 23 percent each year. What is the population of the town in the year 1995
Answer:
86,484
Step-by-step explanation:
The population growth can de determined by using this formula
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value = 489
R = interest rate 23
N = number of years =1995 - 1970 = 25
489 x ( 1.23)^25 = 86,484

Find the value of x in the rectangle ABCD.
Answer:
52°
Step-by-step explanation:
here's your solution
=> we know that the measure of angle of rectangle is 90°
=> 38° + X = 90°
=> X = 90° - 38°
=> X = 52°
hope it helps
Answer:
52 because D is a right angle,so 90 - 38 will give you 32

A total of 629 tickets were sold for the school play. They were either adult tickets or student tickets. There were 71 fewer student tickets sold than adult
tickets. How many adult tickets were sold?
Answer:
350 adult tickets were sold.
Step-by-step explanation:
let x = number of adult tickets
number of student tickets -> x-71
x - 71 + x = 629
2x - 71 = 629
2x = 700
x = 350

A store advertises 15% off an item that regularly sells for $300. what is the sale item? how is a 15% discount similar to a 15% decrease? Explain.
Answer: $255
Step-by-step explanation:
A store advertises 15% off an item which sells for $300. The sale item will then be calculated as:
= $300 - (15% × $300)
= $300 - (0.15 × $300)
= $300 - $45
= $255
The sales price is $255.
A 15% discount is similar to a 15% decrease because in both cases, one has to subtract the value of 15% from the selling price.
