SA of a cylinder = (2 * π * r²) + (2 * π * r * h)
SA = (2 * π * 5²) + (2 * π * 5 * 20)
SA = (2 * π * 25) + (2 * π * 5 * 20)
SA = (2 * π * 25) + (2 * π * 5 * 20)
SA = (157) + (628)
SA = 785
The answer is
A. 785 square meters.

Tim Duncan is shooting free throws. Making or missing free throws doesn't change the probability that he will make his next one, and he makes his free throws 72% of the time. What is the probability of Tim Duncan making all of his next 8 free throw attempts?
Answers
Answer:
Hence, the probability of Tim Duncan making all of his next 8 free throw attempts is:
[tex](\dfrac{18}{25})^8=0.0722204136[/tex]
Step-by-step explanation:
As the probability of one free throw does not depend on the any other i.e. the probability of each throw is independent.
Hence, the probability of making all of his next 8 free throw is calculated as:
Probability of next 8 free throw=Probability of first free throw×probability o f second free throw×··················× Probability of 8th free throw.
i.e. it is given by:
[tex]Probability=\dfrac{72}{100}\times \dfrac{72}{100}\times \dfrac{72}{100}\times \dfrac{72}{100}\times \dfrac{72}{100}\times \dfrac{72}{100}\times \dfrac{72}{100}\times \dfrac{72}{100}\\\\\\Probability=(\dfrac{72}{100})^8\\\\Probability=(\dfrac{18}{25})^8[/tex]
Hence, the probability is:
[tex](\dfrac{18}{25})^8=0.0722204136[/tex]
We have that the he probability of Tim Duncan making all of his next 8 free throw attempts is mathematically given as
[tex]P=0.72^8[/tex]
From the question we are told
Tim Duncan is shooting free throws. Making or missing free throws doesn't change the probability that he will make his next one, and he makes his free throws 72% of the time.

Which statement is true about the circumference of a circle?
It is about three times the diameter.
It is about three times the radius.
It is about twice the radius.
It is about half the diameter.
Answers
C = pi*d
where
C = circumference
pi = 3.14 approximately
d = diameter
So saying "the circumference is roughly 3 times the diameter" is appropriate because pi = 3.14 is roughly 3 if you round to the nearest whole number.
Answer: Choice A) three times the diameter
If 10% of a group ate sandwiches two days in a row, and 40% of the group had a sandwich on the first day, this means that 25% of the group that ate a first sandwich had a second. A. True B. False
Answers
We have P(Day 1 ∩ Day 2) = 0.1 and P(Day 1) = 0.4
We can deduce that 30% of the group ONLY had sandwiches on Day 1 and there's 60% of the group ONLY had sandwiches on Day 2.
We obtain the value 60% = 0.6 from 100%-(10%+30%)=60%
We also can deduce that there 70% of the group that had sandwiches on Day 2
The proportion of people who ate sandwiches on Day 2 GIVEN that they ate sandwiches on Day 1 is given by
P(Day 1 ∩ Day 2)÷P(Day 2) = 0.1÷0.4 = 0.25 = 25%

2(3x - 4) + 10 = 5(x + 4)
First, let's distribute 2 to 3x and -4, then 5 to x and 4.
2(3x) + 2(-4) + 10
6x - 8 + 10
6x + 2 is our first half of the equation simplified. Now let's do the other.
5(x + 4)
5(x) + 5(4)
5x + 20 is our second half of the equation simplified. Now let's put them back in their original spots.
6x + 2 = 5x + 20
Get x on one side - subtract 5x from both sides.
x + 2 = 20
Isolate x by adding 8 to both sides.
x = 18 is our answer.

In order for the data in the table to represent a linear function with a rate of change of –8, what must be the value of m?
A. m = 2
B. m = 3
C. m = 19
D. m = 35
Which is the correct answer???
Answers
Answer: The correct option is (C) 19.
Step-by-step explanation: We are given to find the value of m so that the data the table to represent a linear function with a rate of change of –8.
We know that
the rate of change for a linear function with two points (a, b) and (c, d) is given by
[tex]R=\dfrac{d-b}{c-a}.[/tex]
From the table, we note that the points (10, 27) and (11, m) satisfy the given linear function.
So, the rate of change of the linear function will be
[tex]R=\dfrac{m-27}{11-10}\\\\\\\Rightarrow -8=\dfrac{m-27}{1}\\\\\Rightarrow -8=m-27\\\\\Rightarrow m=27-8\\\\\Rightarrow m=19.[/tex]
Thus, the required value of m is 19.
Option (C) is CORRECT.
The basement of a large department store features discounted merchandise.

Let Upper S Subscript 6 be the sale price for the sixth month and Upper P the original price. Express Upper S Subscript 6 as a function of Upper P Baseline Number .
Answers
S = P(1-0.05t)
Simplifying,

Which of the following shows the solution to the system of equations and explains why? (5 points)
(5, 17), because one of the lines passes through this point
(5, 17), because the point lies between the two axes
(4, 14), because the point does not lie on any axis
(4, 14), because both lines pass through this point

Martina purchased a prepaid phone card for $15.00. Calls cost 5 cents a minute using this card. The credit, C (in dollars), left on the card after it is used for x minutes of calls is given by the following function.
C (x) = 15.00 -0.05x
How much credit is left on the card after Martina uses it for 20 minutes of calls?
Answers
C(x) = 15.00 - 0.05x
C is how many dollars are left after
x minutes.
So if she uses it for 20 minutes, input that into the x.
C(20) = 15.00 - 0.05(20)
C(20) = 15.00 - 1
C(20) = 14.00
After 20 minutes, there are $14.00 left on the card.

To solve for w, all you have to do is divide both sides of the equation by 7. This will get rid of the coefficient on the variable, w, allowing you find out what it equals. 11.2/7 = 1.6, and 7w/7 = w, so w = 1.6.

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 4 cos 3θ. PLEASE HELP ME SOLVE RN I NEED THIS, ALSO INCLUDE THE PROVING PART.
Answers
If
f(r, θ) = f(r,-θ), symmetric to the polar axis or the x-axis
f(r, θ) = f(-r,θ), symmetric to the y-axis
f(r, θ) = f(-r,-θ), symmetric to the pole or the origin
Test for symmetry about the x-axis
f(r,θ): r=4 cos3θ
f(r,-θ): r = 4 cos3(-θ) ⇒ r = 4 cos3θ
∴The graph is symmetric about the x-axis.
Test for symmetry about the y-axis
f(r,θ): r=4 cos3θ
f(-r,θ): -r = 4 cos3θ
∴The graph is not symmetric about the y-axis.
Test for symmetry about the origin
f(r,θ): r=4 cos3θ
f(-r,-θ): -r = 4 cos3(-θ) ⇒ r = -4 cos3θ
∴The graph is not symmetric about the origin.
Grandma baked 96 cookies and gave them to her grandchildren. One of the grandchildren, Cindy, received 5 fewer cookies than she would have received had all of the cookies been evenly divided among the h grandchildren.
How many cookies did Cindy receive?
Write your answer as an expression.
Answers
So Cindy received (96/h) - 5 cookies
even number= 96/n, Cindy gets 96/n-5, the rest receive the rest of the cookies:
96 - (96/n-5) = 96*(1-1/n) + 5 = 96*(n-1)/n + 5.
Then each of them (n-1) receive the previous number divided by (n-1) -Cindy is not there:
each of the other grandchildren receives:
96/n + 5/(n-1), and Cindy receives 96/n-5, it just needs to be positive.
So any number 'n' which divides 96 and 'n-1' divides 5 works.
Indeed ONLY n=6, makes 5/(6-1) possible.
So there are 6 grandchildren:
5 receive 17 cookies, and Cindy gets 11.
If it were evenly distributed, all would have got 96/6 = 16 cookies.
Now 5 get one more cookie, and Cindy 5 less.
WOW. Very nice problem!! Gonna share it :)
