Anthony is laying concrete for a driveway. The driveway is to be 24 feet long by 11 feet wide by 8 inches deep. Answer parts (a) through (c)
(a) Determine the volume of concrete needed in cubic feet.
(b) If 1 cubic yard = 27 cubic feet, how many cubic yards of concrete are needed?
(c) If the concrete costs $36 per cubic yard, what is the cost of the concrete? Concrete must be purchased in whole cubic yards
Answer:
a) The volume of concrete needed in cubic feet is 2,112. b) The number of cubic yards of concrete needed in cubic yards is about 79. c) The cost of the concrete using cubic yards is $2,844.
Step-by-step explanation:
a) The formula of the volume is l*w*d. 24 * 11 * 8 = 264 * 8 = 2,112.
b) The way to find this is that you take 2,112 and divide it by 27. Since the answer is 78.2 repeating, you round it up to 79 so it will fill up all of the concrete.
c) Since you need 79 cubic yards of concrete, you do 79 multiplied by $36 to get the total cost of $2,844.
On a blueprint, the diagram of a building has a height of 23 cm.
The height of the building is x times the height of the diagram.
Which equation represents the height, h, of the building?
A h = 23+x
B X = 23=h
C h = 23x
D
X = 23h
Answer:
C h = 23x
Step-by-step explanation:
The height is h, so we want h = something.
The blueprint height is 23 cm.
The real height is x times 23 cm, so it is 23x.
h = 23x
Answer: C h = 23x

What is the equation for the line that passes through (3, 2) and has a slope
equal to 12
3
Answer:
Step-by-step explanation:
Remark
I'm not sure I know what you intend for the slope. I will take it as 12/3 = 4
If that is the case then what you have so far is
Solution
y = 4x + b
The given point determines b
Givens
x = 3
y = 2
Given point
2 = 4*3 + b
2 = 12 + b
b = 2 - 12
b = -10
The equation is y = 4x - 10
Many professional schools require applicants to take a standardized test.
Suppose that 1000 students take such a test. Several weeks after the test,
Pete receives his score report: he got a 63, which placed him at the 73rd
percentile. This means that... *
Pete scored less than about 73% of the test takers.
Pete scored less than about 63% of the test takers.
Pete scored more than about 63% of the test takers,
Pete scored more than about 73% of the test takers,
Pete's score was below the median.
Answer:
if pete placed in the 73rd percentile, this means that his score was better than 73% of the other test takers, so the fourth option: he scored more than about 73% of the test takers
Step-by-step explanation:
hope this helps :)
The meaning is Pete scored more than about 73% of the test takers.
What is data?Data is information that has been translated into a form that is efficient for movement or processing.
Given situation:
Pete receives his score report: he got a 63, which placed him at the 73rd
percentile.
Percentile is a comparison score between a particular score and the scores of the rest of a group.
So, 73 percentile shows he had done better then 73% of people.
Hence, Pete scored more than about 73% of the test takers.

Which statement could the expression 13 + x represent? Andrea has 13 eggs and bought 13 more. Victoria has 13 flowers. This is greater than the number of flowers Elisa has. Prakhar is 13 years older than his youngest sister. Kai is 13 blocks from home. Jack is a greater distance away.
Kai is 13 blocks from home. Jack is a greater distance away.
In this statement, 13 would represent the distance Kai is from home.... x would equal how much further away Jack is.
Hope this helps!!! Have an amazing day!!!! :)

Answer: y = -3/4x - 0.75
Step-by-step explanation:
The slope needs to be negative so that it's perpendicular to
y = 3/4x - 1
The equation then looks like this
y = -3/4x
We can get an exact y intercept number by using the cordinates
Lets input cordinates (3,-3)
-3 = -3/4(3)
-3 = -2.25 - 75 ( I inferenced )
-3 = -3
now that we got the y intercept lets put it all together
y = -3/4x - 0.75

∠1 and ∠2 are a linear pair. If the m∠2 = 33°, find the m∠1.
Answer:
157 degrees
Step-by-step explanation:
A linear pair is 180 degrees.
180-33 = 157
Answer:
m∠1 = 147°
Step-by-step explanation:
Since both angles are a linear pair, they both add up to 180°. This means that if m∠2 = 33°, then m∠1 would be 180°-33° which is 147°.
180°-33°=147°

Check all the equations that apply to meet the Segment Addition Postulate in segment OQ. OP = 6x + 5, PQ = 4x and OQ = 45.
Answer:
[tex]6x + 5 + 4x = 45[/tex]
[tex]10x = 40[/tex]
Step-by-step explanation:
Given
[tex]OP = 6x + 5[/tex]
[tex]PQ = 4x[/tex]
[tex]OQ = 45[/tex]
The given parameters show that P is a point between O and Q.
So:
[tex]OQ = OP + PQ[/tex]
Substitute values for OP, PQ and OQ
[tex]45 = 6x + 5 + 4x[/tex]
[tex]6x + 5 + 4x = 45[/tex] --- This is an equation
Collect Like Terms
[tex]6x + 4x = 45 - 5[/tex]
[tex]10x = 40[/tex] ------ This is another
Make x the subject
[tex]x = \frac{40}{10}[/tex]
[tex]x = 4[/tex]
