Which pair of angles are alternate exterior angles?
A) 1 and 8
B) 1 and 7
C) 2 and 7
D) 2 and 9
Answer:
Option (C)
Step-by-step explanation:
From the picture attached,
Two lines are the parallel lines and one line is intersecting these lines at two distinct points.
m∠3 = ∠6 [Alternate interior angles]
Since, angles 2 and 7 are the vertically opposite angles,
m∠2 = m∠7 [Alternate exterior angles]
Therefore, angles ∠2 and ∠7 are the pair of alternate exterior angles.
Option (C) is the answer.

The sunshine ski shop makes a profit of $40 on each pair of skis sold. Shop expenses for one week are 2,480. What is the minimum number of pairs of skis that must be sold in one week to make profit of at least $2,000
Answer:
Number of units to sell= 112 units
Step-by-step explanation:
Giving the following information:
Unitary contribution margin= $40
Fixed costs= $2,480
Desired profit= $2,000
To calculate the number of units to be sold, we need to use the following formula:
Break-even point in units= (fixed costs + desired profit) / contribution margin per unit
Break-even point in units= (2,480 + 2,000) / 40
Break-even point in units= 112 units
Answer:
32000
Step-by-step explanation:
The average distance of the Earth from the Sun is 93 million miles. This distance is not constant due to the elliptical rotation of the Earth around the sun and can vary by approximately 1.6 million miles. Which equation can be used to represent the minimum and maximum distances between the Earth and the Sun? |x - target| = varies
Answer:
[tex]|x-93|=1.6[/tex]
Step-by-step explanation:
Let x be the Maximum and Minimum Sun Earth distance
The average distance between Earth and Sun is 93 million miles.
The distance varies by 1.6 million miles.
The equation to find the maximum and minimum value will be
[tex]|x-93|=1.6[/tex]
When modulus function is used one value of the function will be positive and the other will be negative.
[tex]x-93=1.6\\\Rightarrow x=93+1.6\\\Rightarrow x=94.6[/tex]
[tex]-(x-93)=1.6\\\Rightarrow 93-x=1.6\\\Rightarrow x=93-1.6\\\Rightarrow x=91.4[/tex]
So, the maximum and minimum Earth Sun distance is 94.6 and 91.4 million miles respectively.

A student is working two jobs over the summer to pay for a new car. The student gets paid $25 for each lawn that
is mowed (C)and $15 for each pool that is cleaned (y). The student wants to earn $750 to pay for a down payment
on a car.
• Create a model in standard form to represent this linear relationship.
• Identify the x-intercept. Explain what this means in the context of the problem.
• Identify the y-intercept. Explain what this means in the context of the problem.
Identify two combinations that are solutions to this equation. Explain what these combinations mean in the
context of the problem.
Answer:
Step-by-step explanation:
- 25x + 15y = 750
- (30, 0) are coordinates of x-intercept. If there is no pool-cleaning job student has to do 30 lawn-mowing.
- (0, 50) are coordinates of y-intercept. If there is no lawn-mowing job student has to do 50 pool-cleanings.
- ( 15 , 25 ) mean 15 lawn-mowing and 25 pool-cleanings
$25(15) + $15(25) = $750
$375 + $375 = $750

Over which interval does g have a negative average rate of change? Please answer ASAP!
Answer:
b
Step-by-step explanation:
when x is -2, y is 7
when x is -1, y is 5
we can see y is decreasing and it continues to decrease until x is 3
The average rate of change is -12/5 for the interval [-2, 3] which is the negative average rate of change option (B) is correct.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
It is given that:
A function g(x) is shown in the table.
As we know the average rate of change of a function can be given:
The average rate of change = change in y values/change in x values
For the interval [1, 5]
The average rate of change = (2-0)/(5-1) = 2/4 = 1/2
For the interval [-2, 3]
The average rate of change = (-5-7)/(3+2) = -12/5
For the interval [-5, 0]
The average rate of change = (3-0)/(0+5) = 3/5
For the interval [-4, -1]
The average rate of change = (5-2)/(-1+4) = 3/3 = 1
Thus, the average rate of change is -12/5 for the interval [-2, 3] which is the negative average rate of change option (B) is correct.

A boat traveled 27 miles in 2 hours. At this rate, how many miles will the boat travel in ½ hour?
Answer:
6.75 miles
Step-by-step explanation:
First, you need to find the unit rate by dividing 27/2. This equals 13.5. Then, multiply this by 1/2 to get 6.75 miles.
What is the approximate value of x in the diagram below?(Hint: You will need to use one of the trigonometric ratios given in the table.)
Answer:
39.59
Step-by-step explanation:
Just took the quiz
The value of x in the given diagram is 39.59 units.
Correct option is (E).
What is Trigonometry?The trigonometric function, which comprises the sine, cosine, tangent, cotangent, secant, and cosecant, is one of the six mathematical operations used to describe the side ratios of right triangles (csc). Trigonometry can be used to solve problems in surveying, engineering, and navigation where one of a right triangle's acute angles and one side's length are known but the lengths of the other sides need to be computed.
As per the given diagram:
The length of the perpendicular (P) = 27 units
Base angle = 43°
x is the hypotenuse.
To find the value of x we can use the trigonometric ratios given in the question.
sinθ = P/H
Where H is the hypotenuse, P the perpendicular and θ the base angle.
sin(43°) = 27/x
0.682 = 27/x
x = 27/0.682
x = 39.59 units
Hence, the value of x in the given diagram is 39.59 units.

The perimeter of rectangle WXYZ is 34 inches. A scale factor of 1.75 is used to dilate rectangle WXYZ to rectangle ABCD. What is the perimeter of rectangle ABCD?
Answer:
59.5 units
Step-by-step explanation:
A rectangle is a quadrilateral (has four side) in which opposite sides are parallel and the diagonals bisect each other. The perimeter of a rectangle is:
Perimeter = 2(length + breadth) = 2(l + b)
The perimeter of rectangle WXYZ is 34 inches. Therefore:
34 = 2(l + b)
l + b = 17
Rectangle ABCD is formed by dilating rectangle WXYZ by a scale factor of 1.75. Let l' = length of ABCD and b' = breadth of ABCD hence:
Length of ABCD = l' = 1.75l
Breadth of ABCD = b' = 1.75b
Perimeter of ABCD = 2(l' + b') = 2(1.75l + 1.75b) = 2(1.75)(l + b) = 3.5(l + b)
Perimeter of ABCD = 3.5(17) = 59.5 units

3/5x+19−320x−7 simplified is
Answer: 1597x-60/5
Step-by-step explanation:
Answer:
(60 - 1597 x)/5
Step-by-step explanation:
Simplify the following:
(3 x)/5 - 320 x - 7 + 19
Hint: | Put the fractions in (3 x)/5 - 320 x - 7 + 19 over a common denominator.
Put each term in (3 x)/5 - 320 x - 7 + 19 over the common denominator 5: (3 x)/5 - 320 x - 7 + 19 = (3 x)/5 - (1600 x)/5 - 35/5 + 95/5:
(3 x)/5 - (1600 x)/5 - 35/5 + 95/5
Hint: | Combine (3 x)/5 - (1600 x)/5 - 35/5 + 95/5 into a single fraction.
(3 x)/5 - (1600 x)/5 - 35/5 + 95/5 = (3 x - 1600 x - 35 + 95)/5:
(3 x - 1600 x - 35 + 95)/5
Hint: | Group like terms in 3 x - 1600 x - 35 + 95.
Grouping like terms, 3 x - 1600 x - 35 + 95 = (95 - 35) + (3 x - 1600 x):
((95 - 35) + (3 x - 1600 x))/5
Hint: | Combine like terms in 3 x - 1600 x.
3 x - 1600 x = -1597 x:
(-1597 x + (95 - 35))/5
Hint: | Evaluate 95 - 35.
95 - 35 = 60:
