What is the surface area of a cylinder with the given dimensions?
Express your answer to nearest hundredth. Use 3.14 for pi.
Diameter = 14cm.; Height = 6 cm.
Answers
Answer:
The surface area of a cylinder with the given dimensions is 571.48 [tex]cm^2[/tex].
Step-by-step explanation:
To find the surface area, you need to use the formula [tex]2\pi r^2 + h * 2\pi r[/tex] where [tex]r[/tex] represents the radius and [tex]h[/tex] represents the height. In this problem, the expression would be [tex]7^2 * 3.14 * 2 + 3.14*14*6[/tex] = [tex]49 * 6.28 + 3.14 * 84[/tex] = [tex]307.72+263.76[/tex] = 571.48 [tex]cm^2[/tex].

A jar contains 3 blue marbles and 2 red marbles. A marble is randomly selected from the jar and replaced, and then a second marble is chosen.
What is the probability that the blue marble was chosen both times?
Answers
Answer:
3/5
Step-by-step explanation:
3+2=5. 3/5 is the blue marble. You may also say 6/10. It is likely you will pull out a blue marble.
probability that the blue marble was chosen both times 6/10.
What is probability?It is a branch of mathematics that deals with the occurrence of a random event.
Jar contains 3 blue marbles.
Jar contains 2 red marbles.
Total marbles= 5
If she replaced a marble and second time she choose a marble gets blue.
Then, probability of blue marble= 3/5.
But for both the probability for both instance will be 3/5 i.e.,
= 3/5*2/2
= 6/10
Hence, probability that the blue marble was chosen both times 6/10.

What is the estimated probability that at least one of the next four fish Roxanne catches will be a trout?
A. 35%
B. 60%
C. 70%
D. 65%
Answers
The estimated probability that at least one of the next four fish Roxanne catches will be a trout will be 60%. Then the correct option is B.
What is probability?Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.
The simulation result shows at least one of the next four fish Roxanne catches will be
(2635, 2053, 4526, 6994, 4348, 3087, 8323, 3579, 3840, 6389, 3363, 7683)
The number of simulation results showing at least one of the next four fish Roxanne catches will be 12.
The total number of simulation results is 20.
Then the probability will be
P = 12/20
P = 0.6
P = 60%

Step-by-step explanation:
Given that
Tara uses 8.8 pints of white paint
And, the 4 by 5 of this amount represent the white paint
We need to find out the number of paint used by the blue paint
So,
= 8.8 - (8.8 × 4 ÷ 5)
= 8.8 - 7.04
= 1.76 pints
Hence, the blue paints of 1.76 pints is used to paint her bedroom walls

QUESTION: A pentagon has angles that measure 110°, 90°, 80°, 115°, and v. What is v?
Answers
Answer:
145
Step-by-step explanation:
angles in a pentagon add up to equal 540
Hence, 110 + 90 + 80 + 115 + v = 540
( note that we just created an equation that we can use to solve for v )
We now solve for v using the equation created
110 + 90 + 80 + 115 + v = 540
step 1 combine like terms
110 + 90 + 80 + 115 = 395
we now have 395 + v = 540
step 2 subtract 395 from each side
540 - 395 = 145
395 - 395 cancels out
we're left with v = 145

Step-by-step explanation:
a)
[tex]\sin^{2}x + \cos^{2}x = 1[/tex]
Dividing both sides by sin^2x, we get
[tex]1 + \frac{\cos^{2}x }{ \sin^{2}x} = \frac{1}{\sin^{2}x } [/tex]
The 2nd term on the LHS is simply cot^2x and the RHS is simply csc^2x
[tex]1 + \cot^{2}x = \csc^{2}x[/tex]
b)
[tex]2 \sin x = 1[/tex]
[tex] \sin x = \frac{1}{2} [/tex]
[tex]x = \sin^{ - 1} (\frac{1}{2}) = \frac{\pi}{6} [/tex]

I like to use ratios and cross multiply for problems like this. Take the part (1001) over the whole (1300), and that equals x percent of 100 percent.

You have started keeping track of your spending habits. You have noticed that after 12 days you have
$1281 left in your account. You check again after 17 days have passed and your account is now at $861.
How many days will it take before you run out of money (assume you are spending money at a constant
rate)? Marks will be awarded only for the use of equations where t is the time elapsed in days and m is
the money left in your account in dollars.
Answers
Answer:
Time taken to elapse the remaining $861 = 10.25 days
Step-by-step explanation:
Assuming that I am spending at a rate of -x dollars per day
Let initial amount be A
The rate of expenditure = 1281-861/5 = 84 dollars per day
Time taken to elapse the remaining $861 = $861/$84 per day
= 10.25 days
