A sphere has radius 8 ft. If the radius is doubled, what is the effect on the volume?
The volume is multiplied by 6.
The volume is multiplied by 4.
The volume is multiplied by 8.
The volume is doubled.
Answer:
If the radius of the sphere is doubled, the volume would be multiplied by 4. Think of the sphere as a cube instead and if you were to double the sides, the area would be 4 times bigger. Hope this helps! :)
Find value of trigonometric ratio round your answer to four decimal places
tan a
Answer:
tan A = .3429
Step-by-step explanation:
Tangent = Opposite over Adjacent
The opposite of ∠A = 12 and the adjacent = 35
so tan A = 12/35 which equals .3428571492
The question asks us to round to four decimal places
Hence, the answer is .3429

The cost for a pool membership for a family at a community pool is $350 plus $125 per month. A family paid a total of $1,350. How many
months did the family use the pool?
a-11
b-14
c-8
d-12
Answer:
The family used the pool for 8 months
Step-by-step explanation:
We know that the family paid a total amount of $1,350 dollars. We also know that they had to pay $350 dollars for joining the community pool. Lastly, they paid a monthly fee of $125 dollars. The value "x" represents months.
With that being said, here's our equation.
350 + 125x = 1,350
Subtract 350 from both sides and you should get this:
125x=1,000
Finally, divide 125 from both sides to get the x value.
x=8

find the area of the kite.
A. 27 square units
B. 40 square units
C. 18 square units
D. 36 square units
Answer:
36 unit^2.
Step-by-step explanation:
The area is the sum of the 2 triangles with each having base between the points (-2,4) and (-2,-4).
The base is4 - -4 = 8.
Area of a triangle = 1/2 * base * height.
Area of the kite = 1/2 * 8 * 3 + 1/2 * 8 * 6
= 12 + 24
= 36.

Answer:
49 - 9π
Step-by-step explanation:
Area of white portion = area of triangle - area of circle
To find the area of the triangle:
The area of a triangle can be calculated using this formula
[tex]A=\frac{bh}{2}[/tex] where b = base length and h = height
The height given is 7m and the base length given is 14m
That being said we plug in the given values into the formula
[tex]\frac{14*7}{2} \\14*7=98\\\frac{98}{2} =49[/tex]
Hence, the area of the triangle is 49 sq meters.
To find the area of circle
( note that the area is in terms of pi; shown by the answer choices. )
Formula for area of a circle = [tex]A=\pi r^2[/tex]
We are given the diameter ( 6m )
However, we need the radius
To convert diameter to radius we divide by 2
6/2 = 3 so the radius = 3m
Now we plug in 3 into the formula
[tex]A=\pi 3^2\\3^2=9\\A=9\pi[/tex]
Remember we do not apply pi because the answer should be in terms of pi.
Now we subtract the two
Area of white portion = 49 - 9π
Hence, the answer is A
Answer:
49 - 9π

LA = pi*r*l = 3.14*8.5*12.4 = 331
SA = LA + pi*r^2 = 331 + 3.14*8.5^2 = 558
V = 1/3*pi*r^2*h = 1/3*3.14*(8.5^2)*sqrt(12.4^2-8.5^2) = 683
Answer:
331
558
683
Step-by-step explanation:
LA = 3.14x8.5x12.4 = 330.9 = 331
SA = 331+3.14x8.5^2 = 557.9 = 558
V = 1/3x3.14x(8.5^2)x(12.4^2-8.5^2)^0.5 = 682.7 = 683

Answer:
The correct answer is 1/3.
Step-by-step explanation:
The reason why is because there is 3 animals. Then one beaver. So it would be 1/3.
Answer:
0.33
Step-by-step explanation:
Because they are all equal, each animal has to have the same percentage. Because there are 3 options it can land on, the denominator is 3. Because the beaver is 1 of the 3, the answer is 1/3. 1/3 is equal to 0.33 rounded so the answer is 0.33.

Alyssa is trying to pick out an outfit for the first day of school. She can choose
from 4 pairs of pants, 8 t-shirts, 8 sweaters or hoodies, and 5 pairs of shoes.
How many different outfits does Alyssa have to choose from?
The number of different outfits is 1280
How to determine the number of different outfits?From the question, we have the following parameters that can be used in our computation:
8 pairs of pants, 6 t-shirts, 6 sweaters or hoodies, and 2 pairs of shoes
The number of different outfits is equal to the products of the count of each apparel.
This is represented as;
Different outfits = Pants * T-shirts * Sweaters or hoodies * Pairs of shoes
Substitute the known values in the above equation;
Different outfits = 4 x 8 x 8 x 5
Evaluate;
Different outfits = 1280
Hence, there are 1280 different outfits

Sixteen percent of videos are shorter than what
length?
The graph shows the distribution of the lengths (in
seconds) of videos on a popular video streaming site.
The distribution is approximately Normal, with a mean
of 264 seconds and a standard deviation of 75
seconds.
O 39 seconds
O 114 seconds
O 189 seconds
O 339 seconds
Streaming Videos
Answer:
189 seconds
Step-by-step explanation:
16% shorter,
Left side first and second group is 2.5% and 13.5% = 16%
189 is the max of that group
16% of videos on the streaming site are shorter than 189 seconds.
To determine the length at which 16% of videos are shorter, we can use the properties of a normal distribution.
Given that the mean length is 264 seconds and the standard deviation is 75 seconds, we can use a Z-score to find the corresponding percentile.
First, we need to find the Z-score associated with the 16th percentile. This can be done using a Z-table or a statistical calculator. The Z-score corresponding to the 16th percentile is approximately -0.9945.
Using the formula for Z-score:
Z = (X - μ) / σ,
where X is the length of the video, μ is the mean, and σ is the standard deviation, we can rearrange the formula to solve for X:
X = Z * σ + μ.
Substituting the values:
X = (-0.9945) * 75 + 264,
X ≈ 189 seconds.
Therefore, approximately 16% of videos on the streaming site are shorter than 189 seconds. So, the correct answer is 189 seconds.
