A stockpile of dirt is being stored at a construction site. The dirt is roughly shaped like a cone with a height of 45ft and a diameter of 60ft. What is the estimated volume of the dirt pile?
A. 42,390
B. 127,110
C. 1,400
D. 380,000
Answer:
A.
Step-by-step explanation:
The formula for the volume of a cone is [tex]V=\frac{1}{3} h\pi r^2[/tex]
Where h is the height and r is the radius.
In this case, h = 45 ft and r = 60 /2 = 30.
[tex]V =\frac{1}{3} *45\pi *30^2\\V = 42411[/tex]
The answer closest to this is A: 42,390.
Which expressions are equivalent to 2(2x + 4y + x − 2y)?
A) 2(x + 6y) and 2x + 12y
B)2(x + 2y) and 2x + 4y
C)2(3x + 2y) and 6x + 4y
D)2(3x + 6y) and 6x + 12y
Answer:
B
Step-by-step explanation:
2(x+2y)=2x+4y
2x+4y
So option B is the correct answer
Answer:
[tex]2(3x + 2y)[/tex]

Would I need Circumference or Area to calculate the amount of oil it takes to cover a frying pan? Explain your reasoning.
Answer:
area, you would need the area of the frying pan because surface area is the space it would take to cover the surface with oil
What is the surface area of the figure? Use 3.14 for π.

Find the scale factor of the dilation.
The scale factor is
Answer:
2
Step-by-step explanation:
its the wrong anwser
Answer:
0.5
Step-by-step explanation:
Scale factor is the final size (of image D'E'F'G') compared to that of the original (DEFG).
So the dilation factor is 3/6 = 0.5 (less than one means diminution in size.
Find the MEDIAN for the data set: 47, 45, 42, 40, 42, 39, 40,38, 25, 38, 36, 39, 40,
42, 47, 40
Answer:
31.5
Step-by-step explanation:
The MEDIAN is the middle value in a data set.
If the data set has an even amount of values, then the MEDIAN is the MEAN of the two middle values.
For this data set, the middle values are 38 and 25.
To find MEAN, add up all the values and divide by the number of values.
38+25=63
63÷2=31.5
The MEDIAN for this data set is 31.5.

Answer:
C
Step-by-step explanation:
as you look through the options, you can see that they are not both on the inside or out, they are one in and one out so that gets rid of the alternate interior and exterior angle theorems, or you can eliminate both A, B, and D.
since the transversal is going at the same angle through the parallel lines, you can see that if you put the bottom half over the top half, it will be congruent.
this leaves you with C which is then your answer.

Answer:
Step-by-step explanation:
1.48+103+c=180(sum of the interior angles of a triangle)
151+c=180
c=180-151
c=29 degree
2.angle D+angle E=90(in complementary angles sum of two agles is 90 degree)
52+angle E=90
angle E=90-52
angle E=38 degree
3.angle F+angle G
=145+35
=180 degree
yes they are supplementary angles because in supplementary angle sum of two angles is 180 degree)
4.a.radius=diameter/2
=16/2
=8 ft
b.circumference=πd
=3.14*16
=50.24 ft
c.area=πr^2
=3.14*(8)^2
=3.14*64
=200.96 ft^2
6.yes 3,4 and 5 forms a triangle because the sum of two first number is greater than third side.
Answer:
hope it helped :)
Step-by-step explanation:
1)
In ΔABC , sum of angles = 180°
∠A + ∠B + ∠C = 180
48 + 103 + ∠C = 180
∠C = 29°
2)
∠D and ∠E are complementary angles. That is sum of ∠D and ∠E = 90
∠D + ∠E = 90°
52 + ∠E = 90
∠E = 38°
3)
∠F + ∠G = 145 + 35 = 180°
Since sum of angles is 180° , they are supplementary angles.
4)
a) diameter , d = 16 ft => radius = 16/2 = 8ft
b) circumference, c =π d = 3.14 x 16 = 50.24ft
c) Area = π [tex]r^2[/tex] = 3.14 x 8 x 8 = 200.96 square feet
5)
a) ∠M = 72°
b) [tex]\frac{15}{5} = \frac{8}{x}[/tex]
[tex]x = \frac{8 \times 5}{15} = \frac{40}{15} = \frac{8}{3}[/tex]
6)
For the given lengths to be a triangle. sum of squares of small sides must be equal to square of larger length. That is,
[tex]5^2 = 4^2 + 3^2\\25 = 16 + 9\\25 = 25[/tex]
And it's true. So the lengths make a triangle.

Step-by-step explanation:
Determine the missing side of the square.
Answer:
The missing side is 9cm.
How I got my answer:
1. Squares have equal sides.
2. The area is 81cm^2, so we have to divide 81 by 9.
81 : 9 = 9cm.
Answer:
Length of the side W = 9cm
Step-by-step explanation:
A square has all sides equal. So since one side is 9cm, the rest will be 9cm as well. The side marked as 'W' is 9cm.
You can find this in another way (if the length of the sides aren't given) :-
The area is 81[tex]cm^{2}[/tex]
[tex]side^{2}[/tex] gives the area
Let's take the side as x.
So,
[tex]x^{2}[/tex] = Area
[tex]x^{2}[/tex] = 81[tex]cm^{2}[/tex]
x = [tex]\sqrt{81}[/tex]
x = 9cm.
So, each side of the square would be 9cm!

6(-2g-1)=-(13g+2)6(−2g−1)=−(13g+2)
Answer:
g=4
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
6*(-2*g-1)-(-(13*g+2))=0
2.1 Pull out like factors :
-2g - 1 = -1 • (2g + 1)
-6 • (2g + 1) - (-13g - 2) = 0
g - 4 = 0
4.1 Solve : g-4 = 0
Add 4 to both sides of the equation :
g = 4

A student’s work is shown below.
y – 12.7 = 32.75
y – 12.7 – 12.7 = 32.75 – 12.7
y = 20.05
Which is the best statement about the student’s work?
The student solved the problem incorrectly. The student should divide both sides of the equation by -12.7 to create a zero pair.
The student solved the problem incorrectly. The student subtracted incorrectly because 32.75 – 12.7 is 20.68.
The student solved the problem incorrectly. The student should add 12.7 to both sides of the equation to isolate the variable, y.
The student solved the problem correctly. Subtracting 12.7 from both sides of the equation isolates the variable, y.
Answer:
the correct answer is
D the student solved the problem. correctly
Answer: Choice C
The student solved the problem incorrectly. The student should add 12.7 to both sides of the equation to isolate the variable, y.
================================================
Explanation:
We add 12.7 to both sides to undo the "minus 12.7"
We apply the inverse operation to whatever is happening to x.
As another example, solving x-2 = 10 leads to x = 12 after adding 2 to both sides to undo the "minus 2".
------------
The student's steps should look like this
y - 12.7 = 32.75
y-12.7+12.7 = 32.75+12.7
y = 45.45
Notice on the left side of the second step, we have the -12.7+12.7 become 0 and go away.

The MAD for Yolanda’s scores is 9.7, and the IQR is 18.5. Which statement is true?
A. Tobin should compete because his measures of variability show that he is more consistent.
B. Both players are equally qualified because their measures of variability are approximately the same.
C. Yolanda should compete because her measures of variability show that she is more consistent.
D. Both players are equally qualified because their mean scores are about the same and their measures of variability do not provide any additional information.
