Answer: 13.5 in
Step-by-step explanation:
The formula for the volume of a cone is: V = π*r^2*(h/3).
Therefore, when the given numbers are plugged in, it becomes:
1144.53 = (3.14)(9^2)(h/3).
Solving this for h, we get the answer of 13.5 in
use the distributive property to write an equivalent expression to each of the following
(-4x +(2x)
Hey there!
(-4x + (2x)
= -4x + 2x
COMBINE the LIKE TERMS
= (-4x + 2x)
= -4x + 2x
= -2x
Therefore, your answer is: -2x
Good luck on your assignment & enjoy your day!

find the area of the trapezoid
Answer:
the answer is 8
Step-by-step explanation:
it is 8 because if you 2x2 = 4 then + 4 more equal 8. ( or just count the area )
HELPP PLSS!!!!!!!
Find the volume of the following objects.
Answer:
First cone: 29.32
Steps:
1. 3.14(2^2)7/3
2. 3.14(4)7/3
3. 12.56(7/3)
4. 12.56(2.3
5. 29.32
Second cone: 1526.81
Divide 18 in half and so same steps as above to get the answer! :)
Have a great day!!
Please rate and mark brainliest!!
Answer:
Cone 1 = 29.32mi || Cone 2 = 1526.81
Step-by-step explanation:
Step 1) Apply formula (volume of cone)
V= 1/3 * π * r^2 * h [OR] V= π * r^2 * h/3
Step 2) Insert numbers. (cone 1)
V= π * 2^2 * 7/3
Step 3) Insert numbers. (cone 2)
V= π * 9^2 * 18/3 (r=9 because r=1/2 base diameter of circle, 18/2=9)
Step 4) Plug and solve.
Step 5) CHECK YOUR ANSWER BEFORE SUBMISSION. Do it a few times just to make sure it checks out, and then continue!

To solve this equation for x, we must get x by itself. How would we do this?
X + 4 = 7
A. Add 4 to both sides.
B.Subtract 4 from both sides.
Answer:
B
Step-by-step explanation:
If you were to add 4 to both sides, you would have X + 8 = 11
But when you subract, you get X = 7-4, X = 3.
Under his cell phone plan, Justin pays a flat cost of $56 per month and $5 per gigabyte. He wants to keep his bill under $65 per month. Write and solve an inequality which can be used to determine xx, the number of gigabytes Justin can use while staying within his budget
Answer:
56 + 5xx < 65
xx < 1.8
Step-by-step explanation:
56 + 5xx < 65
subtract 56 on both sides
56 + 5xx < 65
-56 -56
5xx < 9
divide by 5 on both sides
5xx/5 < 9/5
xx < 1.8 gigabytes

Answer:
B
Step-by-step explanation:
Convert from mixed numbers to improper fractions:
[tex]\sf area=90 \frac{3}{10}=\dfrac{90 \cdot 10+3}{10}=\dfrac{903}{10}[/tex]
[tex]\sf length=10\frac12=\dfrac{10 \cdot 2+1}{2}=\dfrac{21}{2}[/tex]
Area of a rectangle = length x width
⇒ width = area ÷ length
[tex]\sf \implies width=\dfrac{903}{10} \div \dfrac{21}{2}[/tex]
[tex]\sf \implies width=\dfrac{903}{10} \times \dfrac{2}{21}[/tex]
[tex]\sf \implies width=\dfrac{1806}{210}[/tex]
[tex]\sf \implies width=\dfrac{1806 \div 42}{210 \div 42}[/tex]
[tex]\sf \implies width=\dfrac{43}{5}[/tex]
[tex]\sf \implies width=8\frac35[/tex]

[tex] \\ \\ [/tex]
So first convert length and area from fraction form to decible.
[tex] \leadsto\sf{}Area =90 \dfrac{3}{10} [/tex]
[tex] \\ [/tex]
[tex] \leadsto\sf{}Area = \dfrac{903}{10} [/tex]
[tex] \\ [/tex]
[tex] \leadsto\sf{}Area =90.3[/tex]
[tex] \\ [/tex]
Now convert value length into decibel .
[tex] \\ [/tex]
[tex] \leadsto\sf{}Length =10 \dfrac{1}{2} [/tex]
[tex] \\ [/tex]
[tex] \leadsto\sf{}Length = \dfrac{21}{2} [/tex]
[tex] \\ [/tex]
[tex] \leadsto\sf{}Length = 10.5[/tex]
[tex] \\ [/tex]
We know :-
[tex]\bigstar\boxed{\rm Area~of~rectangle= length \times width}[/tex]
[tex] \\ \\ [/tex]
So:-
[tex] \\ [/tex]
[tex]: \implies\sf Area~of~rectangle= length \times width \\ \\ \\ : \implies\sf 90.3= 10.5 \times width \\ \\ \\: \implies\sf 90.3 \div 10.5=width \\ \\ \\: \implies\sf \dfrac{ 90.3}{10.5}=width \\ \\ \\: \implies\sf \dfrac{ 90 \cancel.3}{10 \cancel.5}=width \\ \\ \\: \implies\sf \dfrac{ 903}{105}=width \\ \\ \\: \implies\sf width = \dfrac{ 903}{105} \\ \\ \\: \implies \underline{\boxed{\sf width = 8.6}} \pink\bigstar[/tex]

1. Yes, since the sum of angles of a triangle is 180 degrees. If there are two right angles in a triangle then the third angle will be zero degrees, which is quite impossible hence this will not form a triangular shape. This will negate the properties of a triangle.
2. No, not always.
Square is a specific form of a parallelogram when all the sides are equal & each interior angle of a parallelogram is a right angle.

Because of the pitch of the attic's roof, a bookcase that is 5 feet high must be place
as shown. What is the measure of the angle formed by the roof and the floor of the attic
The measure of the angle formed by the roof and the floor of the attic is 22.62 degrees.
Right angle triangle
Right angle triangle are triangle that has one of its angles as 90 degrees. The angles formed can be found using trigonometric ratios.
Therefore,
tan x° = opposite / adjacent
tan x° = 5 / 12
tan x° = 0.41666666666
x = tan⁻¹ 0.41666666666
x = 22.6198649482
x = 22.62°
Therefore, the measure of the angle formed by the roof and the floor of the attic is 22.62 degrees.

120 - 4.5x = 45 + 0.5x
Answer:
x = 15
Step-by-step explanation:
You're trying to solve for x by doing two-step equations.
120- 4.5x = 45 + 0.5x
Add 4.5x to both sides and subtract 45 to both sides.
**Note I did 2 things at once to make it easier to look at.
120-45 = 4.5x + 0.5x
75 = 5x
Now divide 75 by 5
x = 15
