Answer:
Cost of the tires in 2008 = 23333 dollars
Step-by-step explanation:
Number of snow tires purchased are represented by,
T = [tex]\frac{500(t+20)}{(t+75)}[/tex]
Where t = duration from year 2000
Similarly, cost of the tires area represented by,
C = [tex]\frac{t+75}{1-.05t}[/tex]
Therefore, cost of T tires = C × T
= [tex]\frac{t+75}{1-.05t}[/tex] × [tex]\frac{500(t+20)}{(t+75)}[/tex]
= [tex]\frac{500(t+20)}{1-0.05t}[/tex]
Now cost of the tires in year 2008 (t = 8 years)
Total cost = [tex]\frac{500(8+20)}{(1-0.05\times 8)}[/tex]
= [tex]\frac{14000}{0.6}[/tex]
= $23333.3
≈ 23333 dollars

Answer:
∠1 = 117°, ∠2 = 63°
Step-by-step explanation:
∠1 = 117° , and ∠2 = 63° because 117° is supplementary to 63°
A ball was thrown upward into the air. The height, in feet, of the ball above the ground t seconds after being thrown can be determined by the expression -16t^2+40t+3. What is the meaning of the 3 in the expression?
Answer:
C.) The ball was thrown from a height of 3 feet
Step-by-step explanation:
In the standard form of a quadratic function, f(x) = ax² + bx + c,
c is the constant term (also known as the y-intercept of the parabola)
In this situation, the ball is thrown up into the air and the flight path will be in the shape of a parabola
The equation y = -16t² + 40t + 3 has a y-intercept of 3, meaning the flight path began at 3 feet above the ground, as you can imagine by looking at the graph of the equation, below. The y-intercept is at (0,3)
find the are of the shape below, giving your answer to 1 decimal place.

How many solutions does the following equation have?
5x+8-7x=-4x+15x+8−7x=−4x+1
Answer:
This has one solution
Step-by-step explanation:
5x+8-7x=-4x+1
Combine like terms
-2x+8 = -4x+1
Add 4x to each side
-2x+4x+8 = -4x+4x+1
2x+8 = 1
Subtract 8 from each side
2x+8-8=1-8
2x = -7
Divide by 2
2x/2 = -7/2
x = -7/2
Answer:
One solution

A bookshelf holds 6 different biographies and 4 different mystery novels. How many ways can one book of each type be selected?
11
30
24
20
Answer:
There are 24 ways to select one book of each type.
Step-by-step explanation:
In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.
The formula to compute the combinations of k items from n is given by the formula:
[tex]{n\choose k}=\frac{n!}{k!(n-k)!}[/tex]
It is provided that there are 6 different biographies and 4 different mystery novels on a bookshelf.
Compute the number of ways to select a biography as follows:
Number of ways to select a biography =
[tex]={6\choose 1}\\\\=\frac{6!}{1!(6-1)!}\\\\=\frac{6\times 5!}{1\times 5!}\\\\=6[/tex]
There are 6 ways to select a biography.
Compute the number of ways to select a mystery novel as follows:
Number of ways to select a mystery novel =
[tex]={4\choose 1}\\\\=\frac{4!}{1!(4-1)!}\\\\=\frac{4\times 3!}{1\times 3!}\\\\=4[/tex]
There are 4 ways to select a mystery novel.
Then the total number of way to select one book of each type is:
[tex]{6\choose 1}\times {4\choose 1}=6\times 4=24[/tex]
Thus, there are 24 ways to select one book of each type.

Since sine= opp/hyp we can use the given info to establish
sin39=15/x
x=23.8
Answer:
d) x≈23.8
Step-by-step explanation:
sin 39 = 15/x multiply by x each side
x sin 39 = 15 divide by sin39
x = 15/sin 39
x = 23.84
x≈23.8

Step-by-step explanation:
Answer:
The answer is C. 5a² - 4a + 1
Step- by- Step:First you want to Distribute the Negative Sign:
= 10a² + 3 − 5a + −1 (2 + 5a² − a)
= 10a² + 3 + −5a + (−1) (2) + −1 (5a²) + −1 (−a)
= 10a² + 3 + −5a + −2 + −5a² + a
Add Like Terms:
= 10a² + 3 + −5a + −2 + −5a² + a
= (10a² + −5a²) + (−5a + a )+( 3+ −2)
= 5a² + −4a + 1

The midpoint, M, of segment GH is M(4, -3). Endpoint G has the coordinates G(-2, 2). Calculate the coordinates of endpoint H. *
Answer:
The point M(Mx, My) is mid-point of GH with G(Gx, Gy) and H(Hx, Hy).
=> 2*Mx = Gx + Hx => 2*4 = -2 + Hx => Hx = 10
=> 2*My = Gy + Hy => 2*(-3) = 2 + Hy => Hy = -8
=> H(10, -8)
Hope this helps!

The coordinate of the point H is (10, -8) if the midpoint, M, of segment GH is M(4, -3). Endpoint G has the coordinates G(-2, 2).
What is a segment bisector?A segment bisector is a line, ray, line segment, or point that divides a line segment into two equal halves at its center.
It is given that:
The midpoint, M, of segment GH is M(4, -3). Endpoint G has the coordinates G(-2, 2).
Let (x, y) be the coordinates of endpoint H
H(x, y)
(x - 2)/2 = 4
x - 2 = 8
x = 8 + 2
x = 10
(y + 2)/2 = -3
y + 2 = -6
y = -8
Thus, the coordinate of the point H is (10, -8) if the midpoint, M, of segment GH is M(4, -3). Endpoint G has the coordinates G(-2, 2).

Answer:
y-4=1/5(x-7)
Step-by-step explanation:
First, you need to find the slope of the line. From the point (2,3) to the point (7,4), the line rises 1 unit while moving sideways 5. Therefore, the slope of the line is 1/5. Hence, the equation of the line is y-4=1/5(x-7). Hope this helps!
Jordan prepares 200 name tags to use at a
meeting. The number for each color of the
name tag is described below.
• 35% of the name tags are blue
•
3
8
of the name tags are yellow
• all of the remaining name tags are red
How many of Jordan’s name tags are red?
Answer:
number of red tags = 200 - 70 - 38 = 92
Step-by-step explanation:
Jordan has a total of 200 name tag and the tags have different varieties of colors. The tags have blue, yellow and red color . Let us find the number of blue tags
number of blue tags = 35% of 200
number of blue tags = 35/100 × 200
number of blue tags = 70
The number of yellow tags = 38
The remaining number of tags are red color. Therefore the number of red tag will be the total number of tag minus the number of blue tags and the number of yellow tags.
number of red tags = 200 - 70 - 38 = 92

To solve the system of linear equations 8 x + 5 y = 18 and 6 x + y = negative 2. By using the linear combination method, Amos decided that he should first multiply the second equation by –5 and then add the two equations together to eliminate the y-terms. His calculations are as shown. 8 x + 5 y = 18. + 6 x minus 5 y = 10. 14 x = 28. StartFraction 14 x Over 14 EndFraction = StartFraction 28 Over 14 EndFraction. X = 2. 6 x + y = negative 2. 6 (2) + y = negative 2. 12 + y = negative 2. 12 + y minus 12 = negative 2 minus 12. Y = negative 14. Amos's solution is (2, –14). What did he do wrong?
Answer:
He forgot to multiply 6x by -5
Step-by-step explanation:
8x + 5y = 18
6x + y = -2
-30x - 5y = 10

Which correctly describes a cross section of the right rectangular prism if the base is a rectangle measuring 15 inches by 8 inches? Select three options..
A right rectangular prism with length 15 inches, width of 8 inches, and height of 6 inches.
A cross section parallel to the base is a rectangle measuring 15 inches by 8 inches.
A cross section parallel to the base is a rectangle measuring 15 inches by 6 inches.
A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.
A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 4 inches by 15 inches.
A cross section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.x
This question is not complete because it lacks the diagram of the Rectangular prism.
Answer:
Attached to this diagram is the necessary diagram
• A cross section parallel to the base is a rectangle measuring 15 inches by 8 inches.
• A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches.
• A cross section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches.
Step-by-step explanation:
A right rectangular prism is a prism that is 3 dimensional in shape and it has 6 rectangular faces.
From the attached diagram, we can see that their is a cross section that is parallel to the base, it has breadth of 8 inches and breathe of 15inches, therefore the option
"• A cross section parallel to the base is a rectangle measuring 15 inches by 8 inches." is correct.
Secondly, when we look at the diagram and check the midpoints thought the 8 inches sides , the cross section perpendicular to the base is a rectangle that has a length of 6 inches and a breadth of 15 inches . Therefore the option
"• A cross section perpendicular to the base through the midpoints of the 8-inch sides is a rectangle measuring 6 inches by 15 inches." Is correct
Thirdly, by observing the attached diaiagram,
• A cross section not parallel to the base that passes through opposite 6-inch edges is a rectangle measuring 6 inches by greater than 15 inches is correct.
