Answer:
The third table.
Step-by-step explanation:
To have a proportional relationship there must be a constant rate of change
6-5 / 9-7 = 1 /2
5-3 /7-4 = 2/3
these are different so this is not a proportional relationship
10-8 /150-120 =2/30
8-5 /120-75 =3/45
these are different so this is not a proportional relationship
10-8 /12-10 =2/2 =1
8-6 /10-8 =2/2= 1
These are the same therefore it is proportional

A circle has a radius of 50 cm. Which one of these is closest to the area?
A. 314 cm
B. 15,708 cm
C. 7,854 cm
D. 157 cm
I need help ASAP!!!
Answer:
The answer is C!
Step-by-step explanation:
I don't have an explanation, it just came to me, sorry..Hope this helps though!
Answer:
7,854 cm
Step-by-step explanation:
We know that Area of the circle is given by:-
Area = \pi r^2πr2
, where r is the radius of the circle.
Given, A circle has a radius of 50 cm.
i.e. r= 50 cm
Then the circle would be Area = \pi(50)^2=(3.14)(2500)=7853.98163397\approx78547\ cm^2π(50)
=(3.14)(2500)=7853.98163397≈78547 cm
Thus, the area of the circle is approximately 7,854\ cm^27,854 cm

When faced with needing additional money during college, which option is NOT true?
Answer:
stealing
Step-by-step explanation:
Answer: C. Paying with additional loans can lead to connections and opportunities
Step-by-step explanation
The options to the questions are:
A. Taking on a job can cut into study time
B. Paying with credit cards can end up costing more money
C. Paying with additional loans can lead to connections and opportunities
D. Taking on a job can make connections that lead to opportunities
Answer:
C. Paying with additional loans can lead to connections and opportunities
Step-by-step explanation:
When faced with needing additional money during college, an individual may choose to take on a job so as to get extra money to finance his or her needs. However, such a venture often leads to a reduction in study time, as working on jobs will also need its own time of execution.
Also, paying for financial needs during college days with a credit card can lead to counting more money on the card. This implies that one can accumulate credit card rewards which can be in form of cashback, or points from certain purchases when using a credit card.
More so, taking a job during college days, will definitely bring connections with different people, and thereby leads to opportunities.
However, paying with additional loans will never lead to connections and opportunities, but rather more debt, that the debtor will have to pay, which may take months or years. And it can only be a burden on the debtor.
Hence, when faced with needing additional money during college the option that is NOT true is Paying with additional loans can lead to connections and opportunities
Mahmoud is doing some plumbing repairs. He runs a pipe through a rectangular wall making a 70 angle. Afterward, he puts the pipe
through another wall which is parallel to the first. Mahmoud can therefore assure the homeowner that the pipe forms a ____ angle
with the second piece of wall.
Answer:
The correct option is;
(D) 70°
Step-by-step explanation:
By running the pipe through the first wall, to the second wall which is perpendicular to the first, we have;
The angle the pipe makes = 70°
Therefore, due to the spring back effect the formed by the pipe when bent 90° is 70°
Therefore, By running the pipe from the second wall, to the third wall which is parallel to the first, and perpendicular to the second wall, the angle the pipe forms is also a 70° angle
Mahmoud can therefore assure the home owner that the pipe forms a 70° angle with the second piece of the wall.

Answer:
here are formulas you havent clearly said how much degrees
Find A U { }. If A is any given set
Answer:
A U { } = A
Step-by-step explanation:
Union is one of the operations that are performed on sets. In union, the elements of involved sets are combined and repetitive elements are removed (written only once)
Given
A U { } = ?
Whenever union will be taken of any set and empty set the answer will be the set.
Similarly, when union of set A will be taken with empty set the result will be set A.
Hence,
A U { } = A

Question 3
find y intercept of the line using (2,1), (3,-10)
[tex]\huge\boxed{(0, 23)}[/tex]
Hey there! We'll solve this problem in three main steps. First, we'll find the slope of the line. Then, we'll find the equation line in point-slope form. Finally, we'll change the equation to slope-intercept form so we can tell what the y-intercept is.
We can use the slope formula, where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are two known points on the line.
[tex]\begin{aligned}m&=\frac{y_2-y_1}{x_2-x_1}&&\smash{\Big|}&&\text{Use the slope formula.}\\&=\frac{-10-1}{3-2}&&\smash{\Big|}&&\text{Substitute in the known values.}\\&=\frac{-11}{1}&&\smash{\Big|}&&\text{Subtract.}\\&=\boxed{-11}&&\smash{\Big|}&&\frac{x}{1}=x\end{aligned}[/tex]
Now that we have the slope, we can use it together with one of the points to get the line in point-slope form. Then, we can distribute and add to get the line in slope-intercept form.
[tex]\begin{aligned}y-y_1&=m(x-x_1)&&\smash{\Big|}&&\text{Use point-slope form.}\\y-1&=-11(x-2)&&\smash{\Big|}&&\text{Substitute in the slope and one point.}\\y-1&=-11x+22&&\smash{\Big|}&&\text{Distribute.}\\y&=-11x+\boxed{23}&&\smash{\Big|}&&\text{Add $1$ to both sides.}\end{aligned}[/tex]
We can now clearly see that the y-intercept of the line is [tex]23[/tex], or [tex](0, \boxed{23})[/tex] as a point.

The fox population in a certain region has a continuous growth rate of 6 percent per year. It is estimated that the population in the year 2000 was 19100.
(a) Find a function that models the population t years after 2000(t=0 for 2000).
Hint: Use an exponential function with base e.
Your answer is P(t)=
(b) Use the function from part (a) to estimate the fox population in the year 2008.
Your answer is (the answer must be an integer)
a)
[tex] P(t) = 19100. e^{0.06t} [/tex]
b) P(8) =30866
Use formula:
[tex] P(t) = P. e^{rt} [/tex]
a)
Here, P = 19100
r = 6% = 0.06
[tex] P(t) = 19100. e^{0.06t} [/tex]
b) t = 2008 - 2000 = 8
[tex] P(8) = 19100. e^{0.06\times 8} [/tex]
[tex] P(8) = 19100. e^{0.48} [/tex]
[tex] P(8) = 19100\times 1.616\\\\
P(8) = 30,865.6\\\\P(8) \approx 30,866[/tex]
The total cost of five pens and eight mechanical pencils is 12.65. The cost of each mechanical pencil is 0.75 cents. Which represents the cost of each pen
Answer:
the cost of each pen is 1.33
Step-by-step explanation:
if you multiply 0.75 by 8 you get 6 after that you subtract 6 from 12.65 which means you have 6.65 which you divide by 5 which equals 1.33

The value of y varies directly with x. If x = 4, then y = 36. Find the value of x when y = 144.
Answer:
16Step-by-step explanation:
Direct variation formula: y = kx
Given
x = 4, y = 36Finding the coefficient k:
36 = 4kk = 36/4k = 9So the function is
y = 9xSolving for x, when y = 144
144 = 9xx = 144/9x = 16
