Answer:
[tex]300\pi[/tex] cubic feet
Step-by-step explanation:
Let r be the radius of cone and h be the height of cone.
Radius of cylinder=r
Height of cylinder=h
Volume of cone=[tex]100\pi ft^3[/tex]
We have to find the volume of cylinder.
We know that
Volume of cone=[tex]\frac{1}{3}\pi r^2 h[/tex]
[tex]100\pi=\frac{1}{3}\pi r^2 h[/tex]
[tex]r^2 h=300[/tex]
Volume of cylinder=[tex]\pi r^2 h[/tex]
Using the formula
Volume of cylinder=[tex]\pi (300)=300\pi ft^3[/tex]
Hence, the volume of cylinder=[tex]300\pi[/tex] cubic feet
Find the value of 9x-5 given that – 2x-3=5.
Simplify your answer as much as possible.
Answer:
The value of 9x - 5 is -41.
Step-by-step explanation:
-2x - 3 = 5
-2x = 5 + 3
-2x = 8
x = -4
9x - 5
= 9(-4) - 5
= -36 - 5
= -41

90% of e is 30. What is e?
Answer:
27
Step-by-step explanation:
Answer:
e = 33.3 (approx. )Step-by-step explanation:
To find out - 'e'
Given,
90 % of e = 30
[tex] = > \frac{90}{100} \times e = 30[/tex]
[tex] = > e = 30 \times \frac{100}{90} [/tex]
[tex] = > e = \frac{100}{3} [/tex]
=> e = 33.3333......
=> e = 33.3 (approx. ) (Ans)
Last year, Isabel opened an investment account with 6600 . At the end of the year, the amount in the account had decreased by 24.5%. How much is this decrease in dollars? How much money was in her account at the end of last year?
Answer:
a. $1,617
b. $4,983
Step-by-step explanation:
a. The account suffered a decrease of 24.5% of the original sum of $6,600.
This amount in cash is:
= 24.5% * 6,600
= $1,617
b. If the account reduced by $1,617, the balance left is:
= 6,600 - 1,617
= $4,983
6=2(y+2) y=?
please help
==========================================================
Explanation:
There are two ways to solve this
The first method will have us distribute the 2 through to each term, then we solve for y
6 = 2(y+2)
6 = 2y+4 .... distribute
2y+4 = 6
2y = 6-4 .... subtract 4 from both sides
2y = 2
y = 2/2 .... divide both sides by 2
y = 1 is the answer
-------------
Or we can solve through this set of steps
6 = 2(y+2)
6/2 = y+2 ...... divide both sides by 2
3 = y+2
y+2 = 3
y = 3-2 .... subtract 2 from both sides
y = 1
Either way, we get the same answer.
-------------
To check the answer, replace every copy of y with 1
Simplifying should lead to 6 on the right side
6 = 2(y+2)
6 = 2(1+2)
6 = 2(3)
6 = 6
Since we get the same thing on both sides, this means the last equation is true. This in turn means the first equation is true when y = 1. Therefore, the solution has been confirmed.
b. Classify the triangle shown by its angles and by its sides.
Answer:
Yes, according to the angles and sides of the hills
Answer:
Answers
1. 40o, obtuse
2. 90o, right
3. scalene
4a. equilateral
4b. isosceles
4c. scalene
5. An acute triangle has 3 acute angles, not just 1. The figure contains a right angle and is therefore a right triangle.
6. obtuse
7. 58o, acute
8. Yes, because the measures add up to 180o.
9. C
10. The triangle would be isosceles, because isosceles triangles have two sides the same length.

Jada received a gift of $180. In the first week, she spent a third of the gift money. She continues spending a
third of what is left each week thereafter. Which equation best represents the amount of gift money g, in
dollars, she has after t weeks? Be prepared to explain your reasoning.
Answer:
180 minus 60 equals 120
Step-by-step explanation:
1/3 of 180 equals 60 so you would take 60 out of 180 to get 120 and 120 would be the amount that she spent the rest of the weeks

12 people are on the elevator to a height of 120 m. The average mass per person is 50 kg. What work does the lift engine do?
Answer:
720000 J
Step-by-step explanation:
The formula is
Work = Force * Distance
Here we have the weight force, which is calculated as w = m * g
acceleration of gravity (g) ≈ 10 m/s
people's mass (m) = 12 * 50 kg = 600 kg
So Force = 10 m/s * 600 kg = 6000 N
Distance = 120 m
Work = Force * Distance = 6000 N * 120 m = 720000 J = 720 kJ
