Complete question :
A traditional "square" bale of hay is actually in the shape of a rectangular prism. Its dimensions are 2 feet by 2 feet by 4 feet. How many square bales contain the same amount of hay as one large "round" bale of height is 4 ft and its width is 5 ft?
Answer:
4 bales
Step-by-step explanation:
Given :
Dimension of rectangular prism = 2 feet by 2 feet by 4 feet
Round Bale:
Height = 4 feets
Width = 5 feets
Volume of 'Square' Bale
Volume = 2 feets * 2 feets * 4 feets
Volume = 16ft³
Volume of 'round' Bale
V = πr²h
radius, r = 4/2 = 2 feet ;
V = π * 2^2 * 5
V = 62.831853 ft³
Volume of 'round' bale ÷ Volume of 'square' bale
62.831853 ft³ ÷ 16 ft³
= 3.9269908
= 4 (nearest whole number)
Answer:
4 square bales

Answer:
h = [tex]\frac{2A}{(b+c)}[/tex]
Step-by-step explanation:
Formula for the area of a trapezoid is,
Area (A) = [tex]\frac{1}{2}(b+c)h[/tex]
Here b and c are the bases and 'h' is the height of the trapezoid.
2A = [tex]2[\frac{1}{2}(b+c)h][/tex]
2A = (b + c)h
[tex]\frac{2A}{(b+c)}=h[/tex]
Therefore, formula for the height of the trapezoid will be,
h = [tex]\frac{2A}{(b+c)}[/tex]

A line passes through (2,8) and (3, 12).
1. What is the slope of this line?
2. What is the y-intercept (show/explain how you know)
3. What is the equation of this line?
Answer:
1. the slope is 4
2. the y intercept is 0
3. the equation of the line is y=4x
Step-by-step explanation:
First let's find the slope of the line (m)
Let's use the formula (y2-y1)/(x2-x1)
here are the points: (2,8) and (3,12)
let's label them
x1=2
y1=8
x2=3
y2=12
now substitute into the equation.
m=(12-8)/(3-2)
m=4/1
m=4
The slope of the line is 4.
Now, to find the y intercept:
You might have noticed that to go from (2,8) to (3,12), you add 1 to x and 4 to y.
Therefore, to find the y intercept, where the line crosses the y axis, you can first subtract 1 from x and 4 to y to get another point that fits on the line (1,4) and then again to get the point: (0,0)
therefore, the y intercept is 0
the most common method of the equation of the line is y=mx+b, where m is the slope and b is the y intercept
therefore the equation of the line is y=4x+0 or y=4x
Hope this helps!

C. Q1 = 99; Q2 = 106.5; Q3 = 109
Step-by-step explanation:
73, 98, 99, 99, 105, 108, 109, 109, 110, 110
✔️The median = Q2
The median = (105+108)/2 = 106.5
✔️Q2 is the middle part of the lower set of data to your left below the median.
73, 98, [99,] 99, 105, 108, 109, 109, 110, 110
Thus, Q2 = 99
✔️Q3 is the middle part of the upper set of data to your right above the median.
73, 98, 99, 99, 105, 108, 109, [109,] 110, 110
Thus, Q3 = 109

If a wheelchair-marathon racer moving at 13.1 miles per hour expends energy at a rate of 645 calories per hour, how much energy in calories would be required to complete a marathon race (26.2 miles) at this pace
Answer:
[tex]1290[/tex] calories
Step-by-step explanation:
Given: The racer moves at [tex]13.1[/tex] miles per hour expends energy at a rate of [tex]645[/tex] calories per hour.
To find: Energy in calories, required to complete a marathon race [tex]26.2[/tex] miles at this pace.
Solution: We have,
The racer moves at [tex]13.1[/tex] miles per hour.
The racer expends energy at a rate of [tex]645[/tex] calories per hour.
So, energy expended while moving [tex]13.1[/tex] miles [tex]=645[/tex] calories.
Now, energy expended while moving [tex]1[/tex] mile [tex]=\frac{645}{13.1}[/tex] calories.
So, energy expended while moving [tex]26.2[/tex] miles [tex]=\frac{645}{13.1}\times 26.2=645\times 2=1290[/tex] calories.
Hence, [tex]1290[/tex] calories of energy is required to complete a marathon race [tex]26.2[/tex] miles at this pace.
The wheelchair-marathon racer would need 1290 calories to complete the marathon race.
SpeedSpeed is the ratio of distance travelled to total time taken. It is given by:
Speed = distance / time
The speed of the racer is 13.1 miles per hour. To complete a 26.2 miles:
13.1 = 26.2 / t
t = 2 hours.
The racer expends energy at a rate of 645 calories per hour, for 2 hours:
Amount of calories = 645 calories per hour * 2 hours = 1290 calories
The wheelchair-marathon racer would need 1290 calories to complete the marathon race.

An oblique prism with a square base of edge length x United has a volume of 1/2 x3 cubic units. Which expression represents the heights of the prism
Answer:
The answer is x units.
Step-by-step explanation:
We are tasked to solve for the expression that represents the height of the prism. We are given with the following values:
length = x² units
volume = x³ units
We will use the formula below:
V = length x height
x³ = x² * height
height = x³/x units
height = x units
The answer is x units.

and you need both sides of the equation to be equal to each other for it to be infinite number of solutions. since -2x is the same as x - 3x and both sides of the equations have +15, then you need to find the value that would make the equations the same. and -2x is that

Maria is planning a party for her friends. Sally's Kitchen charges a fee of
$60 to set up and then $12 per plate. Jimmy's BBQ and Steak charges a fee
of $100 to set up and then $10 per plate. At how many plates will the cost
of Sally's and Jimmy's be the same? How many plates will the cost of
Sally's and Jimmy's be the same? *
Answer:
20 Plates
Step-by-step explanation:
Given that :
Sally's kitchen :
Setup cost = $60
Cost per plate = $12
Jimmy's BBQ :
Setup cost = $100
Cost per plate = $10
Let number of plates = x
Equate both and solve for x :
Sally's kitchen = Jimmy's BBQ
60 + 12x = 100 + 10x
12x - 10x = 100 - 60
2x = 40
x = 40/2
x = 20

1. Steve wants to buy a guitar. The model he wants costs $500.00. He can put down $100, but will need to take out a loan for the remaining $400. If he is charged an interest rate of 8%, about how much interest will he pay on the guitar in one year?
Answer:
In one year he will pay about $32 in interest
Step-by-step explanation:
Simple Interest
Interest is calculated on the original principal only of a loan or on the balance of an account.
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=P.r.t
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
Steve paid a down payment of $100 for a guitar that costs $500, therefore he stills owes P=$500-$100=$400. This is the principal amount that will be paid at an interest rate of 8% = 0.08. In t=1 year, he will pay in interest:
I = $400*0.08*1
I = $32.
In one year he will pay about $32 in interest
In one year he will pay about $32 in interest
What is the formula for interest earned?[tex]I=P\times r\times t[/tex]
Where,I = Interest
P = initial principal balance
r = interest rate
t = time
Steve paid a down payment of $100 for a guitar that costs $500.
Therefore, He stills owes
P=$500-$100
P=$400.
This is the principal amount that will be paid at an
Interest rate of 8% = 0.08.
In t=1 year
He will pay in interest:
[tex]I = $400\times 0.08\times 1[/tex]
[tex]I = $32.[/tex]
Therefore ,In one year he will pay about $32 in interest.
