Answer:
S = 2π(16) + 2π(4)(16)
or
S = 2(3.14)(16) + 2(3.14)(4)(16)
Step-by-step explanation:
The surface area of a cylinder is the sum of the area of it bases and the lateral face. A cylinder has 2 circular base .
The surface area = area of 2 circular base + lateral face area
surface area = 2πr² + 2πrh
surface area = 2πr(r + h)
The surface area equation for a cylinder that has a radius as 4 inches and h as 16 inches can be represented using the formula below.
surface area = 2πr² + 2πrh
where
r = radius
h = height
r = 4 inches
h = 16 inches
S = 2π(4²) + 2π(4)(16)
S = 2π(16) + 2π(4)(16)
Assuming π was given as 3.14 the equation will be as follow
S = 2(3.14)(16) + 2(3.14)(4)(16)

Which best describes the type of association shown in this scatter plot?
•no association
•non-linear association
•positive linear association
•negative linear association
Answer:
Negative linear association/correlation.
Step-by-step explanation:
The type of association that is shown in the scatter plot is negative linear association since it declining at a steady rate with a few outliers. It resembles a line going downwards or sloping downwards.
The best describes the type of association shown in this scatter plot is,
⇒ negative linear association
We have to given that,
A scatter plot is shown in figure.
Since, this scatter plot declining at a steady rate with a few outliers.
And, It resembles a line going downwards or sloping downwards.
Hence, The type of association that is shown in the scatter plot is negative linear association.
Thus, The best describes the type of association shown in this scatter plot is,
⇒ negative linear association

The perimeter of a rectangle is 34 units its width is 6.5 Units
Write an equation to determine the length(l) of the rectangle.
Answer: Length=10.5
Step-by-step explanation: P=34 and W=6.5. This can also be known as Perimeter=W+L+W+L=2(W+L). In this case, it would be 34= 2(6.5 +L). 34=13+2L.(The 2L's are crossed out now because they cancel both out)
-2L -2L (There is a line going down at the equal sign.
34+-2L=13 Subtract 34 from both sides and cancel the two 34's out)
-34 -34
-2L=-21 (Divide both sides by -2) (Cancel out the -2's)
/-2 /-2
L = 10.5

Which statement(s) can be interpreted from the equation for a real estate value, V(C)=228,000(1.03)' where V(C) represents the value of the real estate and t represents the time in years?
The equation is an exponential growth equation.
The equation is an exponential decay equation
The equation is neither exponential decay nor exponential growth
$228,000 represents the initial cost of a real estate that appreciates 3% per year over the course of years.
$228,000 represents the initial cost of a real estate that appreciates 30% per year over the course of t years
$228,000 represents the initial cost of a real estate that depreciates 3% per year over the course of t years
$228,000 represents the initial cost of a real estate that depreciates 30% per year over the course of t years
Answer:
The equation is an exponential growth equation.
$228,000 represents the initial cost of a real estate that appreciates 3% per year over the course of years.
Step-by-step explanation:
the correct equation is: V(C)=228,000(1.03)^t
Hi, to answer this question we have to apply an exponential growth equation:
A = P (1 + r) t
Where:
p = initial cost
r = growing rate (decimal form)
t= years
A =cost after t years
Before applying the formula:
1.03 = 1+r
1.03-1 =r
0.03=r
Replacing with the values given:
A = 228,000 (1+ 0.03)^t
r = 0.03
Since r is in decimal form, we have to multiply it by 100
0.03 x 100 = 3% appreciation per year

The given bar graph shows the percentage of U.S. women in the labor force from 1960 through 2010. The function f left parenthesis x right parenthesis equals 3.5 square root of x plus 38 models the percentage of U.S. women in the labor force, f left parenthesis x right parenthesis , x years after 1960. Use this formula to solve the following questions.
US women in Labor ForceAccording to the model above, approximately what percentage of women will be a part of the work force in 1996? Does the given bar graph verify this result? Explain why or why not. Use complete sentences and proper labels to answer.
Answer:
59% of women will be a part of the work force in 1996
According to the bars, the percentage was in the range of 57.5 - 60.2. This verify the previous result.
Step-by-step explanation:
In the figure attached, the bar graph is shown.
f(x) = 3.5√x + 38
where f(x) models the percentage of U.S. women in the labor force x years after 1960. In 1996, x = 1996 - 1960 = 36. Replacing it into the equation:
f(36) = 3.5√36 + 38 = 59%

what is the answer
Answer:
0
Step-by-step explanation:
12+3×(-4)=
=12+(-12)=
=12-12=0
Answer: 0
Step-by-step explanation:
Since 11 - 15 is in parenthesis you have to do that first and 11 - 15 = -4.
The next step is to multiply 3 and -4 which would be -12
The last step is to add 12 + -12 which equals 0.

What is an
equation of the line that passes through the points (-3,8) and (4,1)?
Answer: y= -1x + 5
Step-by-step explanation:
(-3,8) ( 4,1)
8-1= 7
-3-4 = -7
7/-7 = -1 so the slope is -1 so we will use the formula y=mx+b to find the y-intercept
8= -1(-3) + b
8= 3 + b
-3 -3
b= 5 so the y intercept is 5 now we will write the equation like this y= -1x + 5
A quadrilateral has 2 pairs of congruent angles and 4 congruent sides. What is the name of the quadrilateral?
Answer: Rhombus
A rhombus is a quadrilateral with all four sides the same length. If all four angles are the same (all 90 degrees), then the rhombus is more specifically a square. Any rhombus is a parallelogram which is why we have congruent opposite pairs of angles.
Beccas dad told her that she needs to practice piano for two hours this week so far she has practiced 20 minutes on Monday a half an hour on Tuesday and 15 minutes on Wednesday how much longer does she need to practice?
Answer:
Step-by-step explanation:
She needs to practice piano for 2 hours this week:
Lets add the time she played the piano so far:
Monday + Tuesday + Wednesday
Which is
20 + 30 (half an hour) + 15
= 65 minutes
In which 2 hours is equal to 120 minutes
So,
120 - 65 = 55
She needs to practice for 55 more minutes in this week

As the angles are supplementary, their sum is 180
123 + 3x = 180
3x = 57
x = 19
Answer:
x° = 19°
Step-by-step explanation:
[tex] = > 123 \degree + 3x \degree = 180 \degree \\ \\ = > 3x\degree = 180\degree - 123\degree \\ \\ = > 3x\degree = 57\degree \\ \\ = > x\degree = (\frac{57}{3} )\degree \\ \\ = > x\degree = 19\degree [/tex]

no solution
Answer:
no solution
Step-by-step explanation:
when you substitute [tex]y[/tex] for [tex]-2x+4[/tex] the equation is false
how I solved this:
1. substitute [tex]y[/tex] for [tex]-2x+4[/tex]
[tex]6x+3(-2x+4)=-12[/tex]
2. distribute the 3
[tex]6x+-6x+12=-12[/tex]
3. combine like terms
[tex]12=-12[/tex]
this is incorrect because 12 does not equal -12, so there is no solution

C.The difference between the mean cost to treat dogs at No Ruff Stuff Animal
Hospital and the mean cost to treat cats at No Ruff Stuff Animal Hospital is
about 5 times the MAD. This is a large difference
D.The difference between the mean cost to treat dogs at No Ruff Stuff Animal
Hospital and the mean cost to treat cots at No Ruff Stuff Animal Hospital is
about 10 times the MAD. This is a large difference
Answer:
C. 5 times the MAD
Step-by-step explanation:
The difference between the mean cost to treat dogs at No Ruff Stuff Animal Hospital and the mean cost to treat cats at No Ruff Stuff Animal Hospital is about 5 times the MAD. This is a large difference.
The correct option is C.
What is the mean?In mathematics and statistics, the term "mean" refers to the average of a set of variables. There are various ways to determine the mean, including geometric means, harmonic means, and simple arithmetic means (putting the numbers together and dividing the result by the number of observations).
Given:
The mean cost to treat dogs at No Ruff Stuff Animal Hospital is $224.65.
And MAD = $20.52
The mean cost to treat cats at No Ruff Stuff Animal Hospital is $124.84.
And MAD = 19.75.
The difference between the mean cost to treat dogs at No Ruff Stuff Animal
Hospital and the mean cost to treat cats at No Ruff Stuff Animal Hospital is,
= 224.65 - 124.84.
= 99.81
= 5 x 19.75
Therefore, the difference is 5 times MAD.
