whole number.
Radius is 9 centimeters.
Answers
Answer:
1018
Step-by-step explanation:
Surface area of a sphere is [tex]4\pi r^{2}[/tex]
So, for this question [tex]\pi[/tex] is equal to 22/7
Therefore, 4 multiply 22/7 multiply [tex]9^{2}[/tex]
Answer= 1018.285714
Answer to the nearest whole number = 1018

What is the y-intercept, axis of symmetry and vertex of the following function.
[tex]F(x)=-3x^{2} -6x-5[/tex]
I will give brainilst help please
Answers
F(x) = (-3x0) - (6x0) - 5
F(x) = -5
To find the axis of symmetry and vertex we use the formula -b/2a to find the x coordinate
x = 6/(-3x2)
x = 6/-6
x = -1
Now we need to find the y coordinate so we sub -1 into x.
F(x) = (-3x-1) - (6x-1) - 5
F(x) = 3 + 6 - 5
F(x) = 4
The axis of symmetry and vertex are (-1,4) and the y coordinate is -5. Hope this helps.
Axis of sym = -1
Vertex = (-1, -2)

Solve the system of equations by substitution
Answers
Answer:
x = 4
y = 30
Step-by-step explanation:
Since y = 8x - 2, substitute into 2nd equationThis gives you 3x + 8x - 2 = 42Add 2 to both sides11x = 44Divide both sides by 11x = 4Put this value into either equationI choose the first oney = 8x - 2 = 8 × 4 - 2 = 32 - 2 = 30Answer:
x=4
y=30
Step-by-step explanation:
First re-write the system like this:
[tex] - 8x + y = - 2 \\ 3x + y = 42[/tex]
Now substitute them together:
[tex] - 11x = - 44[/tex]
So
[tex]x = 4[/tex]
put x=4 in one of the equations
[tex]3(4) + y = 42 \\ \\ y = 30[/tex]
so
x=4
y=30

Thirty percent of the beads in a bag are blue. One bead is randomly chosen and replaced. Then a second bead is chosen. What is the probability that neither is blue?
Answers
Answer:
Answer: 12%
Step-by-step explanation:
To find the probability of picking not only a sphere but one that is blue as well, you need to multiply the probabilities of both events because this would show the probability of getting the second event if the first is gotten:
= Probability of sphere * Probability that sphere is blue
= 40% * 30%

Which is greater: 25% of 15 or 15% of 25? Explain your reasoning using mathematical evidence or visual models.
Answers
15% of 25 is the greatest of the two.
Answer:
25% of 15 is 3.75
15% of 25 is also 3.75
15 - 3.75 = 11.25
25 - 3.75 =21.25
Compare and then determine.
11.25 < 21.25
Answer: 25% x 15=25/100 x 15=.25 x 15=3.75
15% x 25=15/100 x 25=.15 x 25=3.75
Now you can clearly see that they are the same.

Answer:
The first question is 699.
The second question is 82.875.
Step-by-step explanation:
To find the are of the floor, we would take the volume formula for the rectangular prism and do it reversed.
V = l*w*h
2,097 = l*w*3
Divied by 3
699 = l*w
Since the area of a floor is l*w, we have found the area of the floor already.
699 feet^2
8 1/2 is 8.5. 3 1/4 is 3.25 To find the volume of a rectangular prism, it is l*w*h
3*8.5*3.25 = 82.875
Answer:
Area of floor= 699 sq ft
Volume of prism = 82 7/8 cubic ft.
Step-by-step explanation:
QUESTION 1
Given:
Volume of rectangular storage room = 2097 ft³
hieght of the storage room= 3ft
To find:
The area of rectangular floor = ?
Solution:
[tex]Volume \: of \: room = Area \: of \: floor \times height \: of \: room \\ 2097 = Area \: of \: floor \times 3 \\ Area \: of \: floor = \frac{2097}{3} \frac{ {ft}^{3} }{ft} \\ Area \: of \: floor = \cancel\frac{2097}{3} \cancel\frac{ {ft}^{3} }{ft} = 699 \: {ft}^{2} \\ \fbox{Area \: of \: floor = \: 699 \: sq.ft. }[/tex]
QUESTION 2
Given:
Length of rectangular prism l = 3 ft
width of rectangular prism w= 3 1/4 ft
Height of rectangular prism h= 8 1/2 ft
To find:
Volume of rectangular prism =?
Solution:
[tex]Volume \: of \: rectangular \: prism= l \times w \times h \\ Volume \: of \: rectangular \: prism = 3 \times (3 \frac{1}{4} ) \times (8 \frac{1}{2} ) \\ Volume \: of \: rectangular \: prism = 3 \times ( \frac{4 \times 3 + 1}{4} ) \times \frac{8 \times 2 + 1}{2} \\ Volume \: of \: rectangular \: prism = 3 \times \frac{13}{4} \times \frac{17}{2} \\ Volume \: of \: rectangular \: prism = \frac{663}{8} \\Volume \: of \: rectangular \: prism = 82 \frac{7}{8} \: cubic \: ft[/tex]

Answer:
A. It represents the cost of the plan if 400 minutes are used.
Step-by-step explanation:
It's A. because on the graph it shows that 400 is on the minute line and the 120 is most likely the cost.
I think.
Answer:
the answer is a
Step-by-step explanation:
In this case the 400 is an x value representing the amount of minutes and 120 is a y value representing the cost. The 120 is dependent on the 400 proving that the answer is a. I hope that helped :))
