3.07 feet is your answer :)
Answer:
The radius is 4.5 ft
Step-by-step explanation:
The volume of a sphere is
V = 4/3 pi r^3
121.5 pi = 4/3 pi r^3
Divide each side by pi
121.5 = 4/3 r^3
Multiply each side by 3/4
121.5 *3/4 = r^3
91.125 = r^3
Take the cube root on each side
(91.125) ^(1/3)= (r^3)^(1/3)
4.5 = r
The radius is 4.5 ft

find the volume of a sphere of radius 3 centimeters.
Answer:
36π cm³
Step-by-step explanation:
The volume (V) of a sphere is calculated using the formula
V = [tex]\frac{4}{3}[/tex]πr³ ← r is the radius = 3
V = [tex]\frac{4}{3}[/tex]π × 3³
= [tex]\frac{4}{3}[/tex]π × 27
= 4π × 9 ( cancelling the 3 and 27 )
= 36π cm³
Here is your answer
B) [tex]36×pi[/tex] [tex]{cm}^{3}[/tex]
REASON:
We know that,
Volume of sphere= [tex] 4/3 pi×{r}^{3} [/tex]
Here r= 3cm
So, V= [tex] 4/3 × pi× {3}^{3} cm^3 [/tex]
= [tex] 4×pi × {3}^{2} cm^3 [/tex]
= [tex] 4×9× pi cm^3 [/tex]
= [tex] 36× pi cm^3 [/tex]

When an elephant sat down to order a half of a third of a quarter of an eighty foot bun and a frankfurter, son was it longer than three feat o shorter
1/2 of 1/3 of 1/4 of 80ft
= 1/2 of 1/3 of (1/4 of 80ft)
= 1/2 of 1/3 of 20ft
= 1/2 of (1/3 of 20ft)
= 1/2 of (20/3) ft
= 20/6 ft
> 18/6 ft
= 3ft
So the order was longer than 3 feet.
Devon exercised the same amount of time each day for 5
days last week. His exercise included walking and swimming.
Each day he exercised, he walked for 10 minutes. He
exercised for a total of 225 minutes last week. What is the
number of minutes Devon swam each of the 5 days last
week? And show how!
Answer:
He spent 35 minutes swimming each day.
Step-by-step explanation:
10x5=50
The multiply by 5 is the numbers of days.
225-50=175
(The 50 minutes subtracted is the time Devon walked)
175 divided by 5 = 35
He spent 35 minutes swimming
Confirm/Check
35 times 5 =175
( Again, The multiply by 5 is the 5 days.)
175+50= 225
Therefore, He swam 35 minutes each day and walked 10 minutes each day.
He swam 175 minutes in total and walked 50 minutes in total

tina’s preschool has a set of cardboard building blocks, each of which measures 9“ x 9“ x 4“. How many of these blocks will Tina need to build a wall 4 inches thick, 3 feet high, and 12 feet long?
Tina will need 64 cardboard building blocks to build the wall.
Step 1: Convert all measurements to inches.
The thickness of the wall is already 4 inches.
The height of the wall is 3 feet. Since 1 foot = 12 inches, then:
[tex]3 \text{ feet} = 3 \times 12 \text{ inches} = 36 \text{ inches}[/tex]
The length of the wall is 12 feet. Therefore:
[tex]12 \text{ feet} = 12 \times 12 \text{ inches} = 144 \text{ inches}[/tex]
Step 2: The volume of a rectangular wall can be found using the
formula:
[tex]\text{Volume} = \text{Length} \times \text{Height} \times \text{Thickness}[/tex]
Substituting the values:
[tex]\text{Volume} = 144 \text{ inches} \times 36 \text{ inches} \times 4 \text{ inches}[/tex]
[tex]\text{Volume} = 20736 \text{ cubic inches}[/tex]
Step 3: The dimensions of the block are 9 inches x 9 inches x 4 inches,
so:
[tex]\text{Volume}_{\text{block}} = 9 \text{ inches} \times 9 \text{ inches} \times 4 \text{ inches}[/tex]
[tex]\text{Volume}_{\text{block}} = 324 \text{ cubic inches}[/tex]
Step 4: To find out how many blocks are needed for the wall, divide the
total volume of the wall by the volume of one block:
[tex]\text{Number of blocks} = \frac{\text{Volume of wall}}{\text{Volume of one block}}[/tex]
[tex]\text{Number of blocks} = \frac{20736 \text{ cubic inches}}{324 \text{ cubic inches}}[/tex]
[tex]\text{Number of blocks} = 64[/tex]

What is the phase shift of a periodic function?
Answer and Explanation :
To find : What is the phase shift of a periodic function?
Solution :
The Phase shift is defined as a horizontal shift in a function in any direction.
Horizontal stretches will change the period of the function and that horizontal shift is called a phase shift or the amount of shift in a wave horizontally.
The phase shift is measured in degrees.
Refer the attached figure below for the pictorial representation of teh phase shift.
In the figure, [tex]\frac{\pi }{2} \text{ to } \pi[/tex] is showing the phase shift.
Example - Taking a general example of sin function
[tex]y = A \sin(B(x + C)) + D[/tex]
In this the phase shift is at C (positive is to the left).
What does 0.5(-12p - 4) equal to?
Answer:
Use the distributive property to solve this equation: a(-b - c) = -ab - ac
Step-by-step explanation:
1. 0.5(-12p - 4) =
-6p - 2 is the answer.
Hope this helped!!!!
~Shane
Final answer:
The expression 0.5(-12p - 4) simplifies to -6p - 2 by distributing the 0.5 across each term inside the parentheses, resulting in the multiplication of -12p by 0.5 to get -6p, and -4 by 0.5 to get -2.
Explanation:
The expression 0.5(-12p - 4) can be simplified by distributing the 0.5 across the terms inside the parentheses. This is done by multiplying 0.5 by each term in the parentheses individually. The steps are as follows:
Multiply 0.5 by -12p, which gives us -6p.
Multiply 0.5 by -4, which gives us -2.
Combine these results to get the simplified expression, which is -6p - 2.
Therefore, 0.5(-12p - 4) equals -6p - 2.

You want to buy a tent in the shape of a pyramid. The rectangular base is 35 square feet, with a height of 4 feet. What is the volume of the tent? Round your answer to the nearest hundredth.
Answer:
46.67 cubic feet
Step-by-step explanation:
The formula for volume of a pyramid is
V = (1/3)Bh where B is the area of the base, and h is the height.
We are givne B = 35 and h = 4. Plug those values in and simplify...
V = (1/3)(35)(4)
V = (1/3)(140)
V = 140/3
V = 46 2/3 cubic feet, which is 46.666667, or 46.67 rounded to the nearest hundredth
Answer:
46.67 cubic feet
Step-by-step explanation:
Write the slope intercept form of -y = 4-x
Slope intercept form:
y=mx+b
Right now we have:
-y=4-x
x=1 because it’s not being multiplied by anything
y-intercept = 4 because it’s what you’re adding
Then we just need to move 4 to the other side of “x”
And with that, we conclude with a line in slope intercept form:
-y=x-4
It’s a negative 4 and a positive x, because you’re supposed to do the opposite
If it’s a negative, you add. If it’s a positive, you subtract.

Is there a rigid transformation that would map ΔABC to ΔDEC
Answer:
Yes. a rotation about point c
Step-by-step explanation:
just answered it.
A rigid transformation is a transformation that preserves the shape and size of an object. It includes translations, rotations, and reflections. Without specific information about the coordinates or measurements of the triangles, it is not possible to determine if a rigid transformation exists.
Explanation:A rigid transformation is a transformation that preserves the shape and size of an object. It includes translations, rotations, and reflections. In order for triangle ΔABC to be mapped to triangle ΔDEC, there must be a combination of translations, rotations, and reflections that can bring the two triangles into congruence.
However, without specific information about the coordinates or measurements of the vertices of the triangles, it is not possible to accurately determine if a rigid transformation exists that can map ΔABC to ΔDEC.
