The volume of the sphere with a radius of 9.1ft is 3256.55cubic feet.
We have given that, the radius of the sphere is 9.1ft.
We have to determine the volume of the sphere
What is the formula for the volume of the sphere?The volume of the sphere is given by
[tex]V=\frac{4}{3}\pi r^3[/tex]
r is the radius of the sphere
V- is the volume of the sphere
So use the given value in the formula so that,
[tex]V=\frac{4}{3}\pi (9.1)^3[/tex]
[tex]V=3156.55082 ft^3[/tex]
Therefore the volume of the sphere with a radius of 9.1ft is 3256.55cubic feet.

Answer:
Step-by-step explanation:
The y values differ by 1. They are also 1 larger than the x value.
The equation is y = x + 1
Use x = 4 ans an example
y = x + 1
x = 4
y = 4 + 1
y = 5
At least for this example the equation works. It will for all the others as well.
Carla served her mango pie on a 14 inches diameter dish. She wanted to tie a ribbon around the dish to make it a little more attractive. How long does the ribbon need to be in order to fit around the dish?
By finding the circumference of the plate, we conclude that the ribbon must be 43.96 in long.
How long does the ribbon need to be?
Remember that for a circle of radius R, the circumference is:
C = 2*pi*R
In this case, the ribbon must be equally long to the circumference of the plate. We know that the diameter of the plate is 14 inches, and the radius is half of that, then we get:
R = 14in/2 = 7in
Replacing that on the circumference equation we get:
C = 2*3.14*7in = 43.96 in
The ribbon must be 43.96 in long.

which transformation of y = f(x) moves the graph 9 units to the left and 5 units down
Answer:
y=f(x+9)-5
Step-by-step explanation:
to move the graph 9 units to the left, you would need to add 9 to the variable (which is x) - so that transformation for y=f(x) would look like this:
y=f(x+9)
then, to move the graph 5 units down, you would need to subtract 5 from f(x), so the transformation for y=f(x) that moves the graph 5 units down would be:
y=f(x)-5
now, you would put that all together and it would look like this:
y = f (x+9) -5

The correct regarding the angles of the triangles are,
⇒ m ∠Y < m ∠Z < m ∠X
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Since, Given that;
m ≥ 6, we will substitute 6 in for m.
This makes;
XZ = m-3 = 6-3 = 3.
XY = m+8 = 6+8 = 14.
YZ = 2(6)+3 = 12+3 = 15.
Hence, This makes the sides, in order from least to greatest as;
XZ < XY < YZ.
Thus, The angles associated with these are opposite their corresponding sides; XZ corresponds with Y; XY corresponds with Z; and YZ corresponds with X.
This means correct regarding the angles of the triangles are,
⇒ m ∠Y < m ∠Z < m ∠X
Thus, The correct regarding the angles of the triangles are,
⇒ m ∠Y < m ∠Z < m ∠X

Find the equation of a line that passes through the point (4,2) that is perpendicular to the line y=4/3x
Answer:
Step-by-step explanation:
The a line that is perpendicular to the reference line will have a slope that is the negative inverse of the slope of the reference line. We'll look for a line that has the form y=mx+b, where m is the slope and b is the y-intercept. The reference line y=(4/3)x has a slope of (4/3) and a y-intercept of 0 (it crosses the y axis at x = 0).
The negative inverse the the slope (4/3) would be -(3/4).
The new line will be y = -(3/4)x + b.
To find point, use the given point and solve for b:
y = -(3/4)x + b
y = -(3/4)x + b for point (4,2)
2= -(3/4)(4) + b
2= -3 + b
b = 5
The equation of the perpendicualr line is y = -(3/4)x + 5

III is a quadratic equation in factored form. The graph for a quadratic equation is shaped like a U or an upside down U, so it cannot be that one either.

Answer:
The answer is given in the picture
Step-by-step explanation:
PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECT PLEASE
Answer:
x = 10/3 , y = 25/3
Step-by-step explanation:
Let's solve your system by substitution.
5x−2y=0 ; 5x+10y=100
Step 1: Solve 5x−2y=0 for x:
5x−2y=0
5x−2y+2y=0+2y (Add 2y to both sides)
5x=2y
5x=2y
5x/5=2y/5 (Divide both sides by 5)
x=2y/5 (Simplify)
Step 2: Substitute 2y/5 for x in 5x+10y=100:
5x+10y=100
5 2/5y +10y=100
12y=100 (Simplify both sides of the equation)
12y/12=100/12 (Divide both sides by 12)
y=25/3
Step 3: Substitute 25/3 for y in x=2/5y
x=2/5y
x=2/5 * 25/3
x=10/3 (Simplify both sides of the equation)
At the end we have the following answers :
x = 10/3
y = 25/3

8 x 8 = 64
then 64/2
32
8x8 (again) = 64
64+32 = 96
Answer:
96 in^2. Find the area of the square, then the area of the triangle. After that, add them together.
Step-by-step explanation:
First, let's find the area of the square:
A = lw
A = 8 x 8
A = 64
Now, let's find the area of the triangle.
A = 1/2lh
A = 1/2(8)(8)
A = 1/2(64)
A = 32
Now, all we have to do is add 64 and 32 to get the total area
64 + 32 = 96
What is the probability that a five-card poker hand contains exactly one ace?.
The probability of selecting exactly one ace is its likelihood
The probability that a five-card poker hand contains exactly one ace is 29.95%
How to determine the probability?There are 4 aces in a standard deck of 52 cards.
The probability of selecting an ace would be:
p = 4/52
Also, there are 48 non-ace cards in the standard deck
So, the probability of selecting a non-ace after an ace has been selected is:
p = 48/51
The probability of selecting a non-ace up to the fifth selection are:
After two cards have been selected is: 47/50.After three cards have been selected is: 46/49.After four cards have been selected is: 45/48.The required probability is then calculated as:
P(1 Ace) = n * (4/52) * (48/51) * (47/50) * (46/49) * (45/48)
Where n is the number of cards i.e. 5
So, we have:
P(1 Ace) = 5 * (4/52) * (48/51) * (47/50) * (46/49) * (45/48)
Evaluate
P(1 Ace) = 0.2995
Express as percentage
P(1 Ace) = 29.95%
Hence, the probability that a five-card poker hand contains exactly one ace is 29.95%
