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
Answers
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.

Answers
Answer: 0.8 or 80%
Step-by-step explanation:
there’s 8 ppl with hazel eyes, which leaves 10 others that don’t have hazel eyes. So try dividing 8 by 10, which is 0.8 which also equals to 80% that’s how I got this answer. I hope this helps!

6(-2g-1)=-(13g+2)6(−2g−1)=−(13g+2)
Answers
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

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.

A recipe for modeling clay requires 1/3 cup of salt. How many recipes of clay can Carla make with 7 3/4 cups of salt?
Answers
Answer:
About 23 cups
Step-by-step explanation:
Answer:
- The error is: (31/4) (1/3)
- The correct solution is: 93/4 =23 1/4 (Carla can make approximately 23 recipes with the clay).
Step-by-step explanation:
1. Carla must divide 31/4 ÷ 1/3 as following:
- Take the reciprocal of .
- Multiply the numerators and the denominators.
Then:(31/4) (1/3) = (31)/4 (3)/1 = 93/4
2. As a mixed number: 93/4 = 23 1/4
3. Therefore, Carla can make approximately 23 recipes with the clay.
- The error is:
- The correct solution is: (Carla can make approximately 23 recipes with the clay).
A 7 m rope is attached to the wall of a garage. A dog’s collar is attached to the rope, allowing the dog to safely roam the yard. What is the area that the dog has to roam outside?
Answers
Well, if you think about it, its a half circle. We know that if the dog pulls straight then the radius if this were a full circle would be 7. So the Area of a circle is A=Pi Radius Square. For us it will be divided by 2 since its a half circle. So were going to round pi to 3.14 and now..
3.14(49)=153.86. So that is an area of the full circle. DIvided by 2 we get 76.93.
I am pretty sure its correct so your answer is 76.93 m

Non-shaded region area:
A= 3.14 x 7^2=153.86 cm²
The whole circle area:
A=3.14 x 11^2= 379.94 cm²
Area for ONLY the shaded region:
A= 379.94 - 153.86= 226.08 cm²
a = pi * r^2
a = 3.14 * 7^2
a = 3.14 * 49
a = 153.86
a = 3.14 * 11^2
a = 3.14 * 121
a = 379.94
subtract the smaller area from the larger area:
379.94 - 153.86 = 226.08 sq cm

Someone help me with these immediately
Answers
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)

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.
Determine the missing side of the square.
Answers
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!
