Answer:
8138.88 cubic unit.
Step-by-step explanation:
Given that,
Radius, r = 12
Height, h = 18
We need to find the volume of the prop. The volume of a cylinder is given by the formula as follows :
[tex]V=\pi r^2 h\\\\V=3.14\times 12^2 \times 18\\\\V=8138.88\[/tex]
So, the volume of the cylinder is 8138.88 cubic unit.

Marie donated 36% of her comic books to a
school. If she donated 135 comic books, how
many did she own before her donation?
Answer: 375
Step-by-step explanation:
Let x equal the number of comic books before her donation.
x × 0.36 = 135
135/0.36 = 375
Rope packaged in 80-foot lengths
must be cut into 12-foot pieces to
do a certain job. If 28 such pieces
of rope are needed for the job, how
many packages of rope are needed?
(A) 4
(B) 5
(C) 6
(D) 7
(E) 28
Answer:
it would be 5
Step-by-step explanation:
any of the answer could have really worked (not 4 since that gives you less then what is needed) but in the end it would have been 5 because 5 leaves you with only 5.33 feet of rope left
80* any one of the four numbers (ex: 5) = your answer that you got (ex: 400)
then you divide that number by 28 (ex: 33.33) and if you want to go the extra mile then do the number that you got by dividing 28 minis the number of rope pieces needed
the whole thing >
80* 5 = 400
400/28 = 33.33
33.33- 28 = 5.33
hope this helps! :)

Answer: 112 degrees
============================================================
Explanation:
If we assume ABCD is a parallelogram, then the adjacent angles are supplementary.
So,
A+D = 180
A+68 = 180
A = 180-68

Segment MP is a diameter of circle O.
Circle O is shown. Line segment M P is a diameter. Line segment N O is a radius. Angle N O P is 150 degrees.
Which equation can be used to find mArc M N?
mArc M N – 150 = 360
Answer:
[tex]arc\ MN + 150 = 180[/tex]
Step-by-step explanation:
Given
[tex]\angle NOP = 150^\circ[/tex]
See attachment for circle O
Required
Find [tex]arc\ MN[/tex]
The sum of angles in a semi-circle is 180 degrees.
So:
[tex]arc\ MN + \angle NOP = 180[/tex]
This gives:
[tex]arc\ MN + 150 = 180[/tex]
Hence, the equation is: [tex]arc\ MN + 150 = 180[/tex]

What is the distance between (2. 6) and (7, 6)
Answer:
5
Step-by-step explanation:
Hey There!
So first off the y values are the same so to find the distance between the two points all we have to do is subtract the largest x value from the smallest x value
7-2=5
Therefore the distance between the two points is 5
Answer: 5
Step-by-step explanation:
D = √(x₂ - x₁)² + (y₂ - y₁)²
x₁ =2 y₁ =6 x₂ =7 y₂ =6
D =√(7-2)² +(6-6)²
D=√(5)² +(0)²
D =√25
D=5

A cylinder has a volume of 36 cubic inches. What is the volume of a cone if it has the same radius and height as the cylinder?
Answer:
12 cubic inches
Step-by-step explanation:
volume of a cylinder= pi*r2*height
but we are given 36 as cylinder volume.
Therefore , 36 = pi*r2* height
r2*height = 36/pi, let call this equation 1
volume of a cone = pi*r2*height/3;
but from equation 1, r2*height =36/pi, substituting this value in volume of cone.
volume of cone= pi*(36/pi)/3 = 12 cubic inches

"The difference between the circumference and diameter of a wheel is 18cm. Find the radius of the wheel. Use 3.14 for Pi. Round to the nearest tenth."
Answer:
[tex]4.2\ \text{cm}[/tex]
Step-by-step explanation:
d = Diameter of wheel
The difference between the circumference and diameter of a wheel is 18 cm.
[tex]2\pi r-d=18\\\Rightarrow \pi d-d=18\\\Rightarrow d(\pi-1)=18\\\Rightarrow d=\dfrac{18}{\pi -1}\\\Rightarrow d=\dfrac{18}{3.14-1}\\\Rightarrow d=8.41\ \text{cm}[/tex]
The diameter of the wheel is 8.41 cm so the radius will be [tex]\dfrac{8.41}{2}=4.205\approx 4.2\ \text{cm}[/tex].

Answer:
4 8.95h + 10 < 115
Step-by-step explanation:
Answer: 4) 8.95h + 10 < 115
Step-by-step explanation:
We know the inequality will be equal to less than 115 since it states that the order was less than $115.
The equation would look like: some amount of shin guards times 8.95 each + $10 shipping = less than $115
8.95h + 10 < 115
(h in the given equation is the amount of shin guards)

units?
Answer:
[tex]21\ \text{square units}[/tex]
Step-by-step explanation:
The points are [tex]D(-3,5), E(-3,-2)[/tex] and [tex]F(3,0)[/tex].
Area of a triangle is given by
[tex]A=\dfrac{D_x(E_y-F_y)+E_x(F_y-D_y)+F_x(D_y-E_y)}{2}[/tex]

Fred's age is 82.

Catherine's age is 14.
Blake's age is 12.
The equation that represents Fred's age is: 1 + 3x =
Where x is Amanda's age
Fred and Amanda's age : 109 = 1 + 3x + x
4x + 1 = 109
4x = 109 - 1
4x = 108
x = 108 / 4
x = 27
Fred's age = 1 + (3 x 27) = 82
The equation that represents Blake's age is: b = 2c - 16
Where: b = Blake's age
c = Catherine's age = 2 + b
b = 2(2 + b) - 16
b = 4 + 2b - 16
16 - 4 = 2b - b
12 = b
Catherine's age = 12 + 2 = 14

Find the area and the circumference of a circle with radius 2yd. Use the value 3.14 for pie and do not round your answer. Be sure to include the correct units in your answer
Answer:
circumference: 12.56 yd
area: 3.14(2 yd)² = 12.56 yd²
Step-by-step explanation:
The circumference formula is C = 2πr (pi, not pie), where r is the radius.
When r = 2 yd and π ≈ 3.14, the circumference is:
C = 2(3.14)(2 yd) = 12.56 yd

Answer:
$3
Step-by-step explanation:
Since he’s leaving a 20% tip, we need 20% of 15.
To solve, multiply 20/100 (20%) by 15:
20/100*15 = 300/100 = 3
He will leave a $3 tip.
Answer:
$3
Step-by-step explanation:
To solve this problem, first, one must convert the percent of the tip to decimal form. This can be done by dividing the percent by 100. Then one will multiply this value by the total bill.
20% * 15
= 0.2 * 15
= 3
