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?
Answers
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 product of a binomial and a trinomial is x3+3x2-x+2x2+6x-2 Which expression is equivalent to this
product after it has been fully simplified?
Answers
Explanation:
X^3 stays the same because there are no other cubed numbers in the problem
Next you combine the x^2s
The x^2s are +3x^2 and +2x^2
Since they are both positive, you add them: 3x^2 + 2x^2 = 5x^2
Next you do the x values
-x and +6x, also known as 6x - x = 5x
Lastly, you just add in the -2 and get:
X^3 + 5x^2 + 5x - 2

[tex]in triangle ABC, AB=7, BC=10, and the measure of angle B=80, to the nearest 10th, what is b[/tex]
Answers
Answer:
b = 11.0
Step-by-step explanation:
From the given properties of the triangle,
b = AC
Applying the cosine rule, we have;
[tex]b^{2}[/tex] = [tex]a^{2}[/tex] + [tex]c^{2}[/tex] - 2acCos B
= [tex]10^{2}[/tex] + [tex]7^{2}[/tex] - 2(10 x 7) Cos 80
= 100 + 49 - 140 x 0.17365
= 149 - 24.311
= 124.689
b = [tex]\sqrt{124.689}[/tex]
= 11.1664
b = 11.0

Each of the 90 apartments in an apartment complex is having its carpet replaced. Two apartments were done on the first day, and three more were done on the second day. If five apartments can be done per day from now on, how many more days will be needed to finish the project?
Answers
Answer: 17 days
Step-by-step explanation:
Two were done on the first day and then 3 on the second.
The number of apartments left is:
= 90 - 2 - 3
= 85 apartments
They are to be done 5 per day:
= 85 / 5
= 17 days
It would take 17 days to do the remaining at 5 apartments per day.

Rope packaged in 80-foot lengths

of rope are needed for the job, how
many packages of rope are needed?
(A) 4
(B) 5
(C) 6
(D) 7
(E) 28
Answers
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

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

A cable company uses the formula S = 20,000 (1 + 0.08)^y to estimate the number of subscribers, S, that use their service after y years. If there were 20,000 cable television subscribers when the cable company began, what is the meaning of the expression (1 + 0.008) ^y?
Answers
Answer:
the expression above is
y = Subscribers after time t = S
a = Initial Subscribers =20,000
r = Growth rate = 0.08 = 8%
t = time in years = y
Step-by-step explanation:
A cable company uses the formula S = 20,000 (1 + 0.08)^y to estimate the number of subscribers, S, that use their service after y years. If there were 20,000 cable television subscribers when the cable company began, what is the meaning of the expression (1 + 0.008) ^y?
The above question represents Exponential growth
Exponential growth formula =
y = a( 1 + r) ^t
Where:
y = Population after time t
a = Initial Population
r = Growth rate
t = time in years
S = 20,000 (1 + 0.08)^y
Hence, the expression above is
y = Subscribers after time t = S
a = Initial Subscribers =20,000
r = Growth rate = 0.08 = 8%
t = time in years = y
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
Answers
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

Fred's age is 82.
Amanda's age is 27.
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
