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

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

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.

The value of y varies directly with x. If x = 4, then y = 36. Find the value of x when y = 144.
Answer:

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

find the slope of the following ^ :))
|
Answer:
m [slope] = 0
Step-by-step explanation:
When the slope is 0, x cancels out so the y value will remain the same.
There are several methods to finding slope but the easiest way to do this is by dividing the second y value - first y value by the second x value - first x value.
m = ∆y/∆x = y2-y1/x2-x1
You y2 and x2 are interchangable with y and x, because y1, and x1 are part of the starting coordinate,.
The reason you subtract the second
value from the first is because in a directly proportional relationship, y increases as x increases so the next x values will have a greater y value, this is a measure of steepness.
So the slope is:
-1 - -1 / 3 - -2 = -1 + 1 / 3 + 2 = 0 / 5 = 0.

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

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]

A video screen is 16 in. by 12 in. tall. What is the width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall?
Answer:
16 inches, and 10 inches tall, aka Answer D.
So because, they are asking the largest image for the photograph,
so 8 * 2 = 16
and 10 * 2 = 20 but 20 can't go into 12.
Step-by-step explanation:
I think this is right sry if its not
The width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall is 8 in option (B) 8 in is correct.
What is a scale factor?The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
We have:
A video screen is 16 in. by 12 in. tall.
To find the width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall, we can use the scale factor:
Applying the similarity law:
6/12 = 4/x
1/2 = 4/x
x = 4×2
x = 8 in
Thus, the width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall is 8 in option (B) 8 in is correct.
