For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Sara had 136 dollars to spend on 8 books. After buying them she had 16 dollars. How much did each book cost ?
Answers
Answer:
Each book cost 15 dollars.
Here’s the work: Sara had 136 dollars and spent some money on 8 books. After buying them she had 16 dollars left. So she spent 136 - 16 = 120 dollars on books. Since she bought 8 books with that money, each book cost her 120 / 8 = 15 dollars.
Explanation:
Sara had $16 left, so
136-16=120
this means she spent $120 on books
She bought 8 books, so
120/8= 15
therefore, 1 book costs $15

Step-by-step explanation:
QUESTION 7:
We are trying to find angles 1 and 2.
Known angle: 107˚.
In this question, we have 2 parallel lines with a transversal. A transversal is a line that passes through 2 parallel lines making it so that the angles on both sides are exactly the same.
Step 1: Find the measures of all the angles using the one we already know.
I will start with the angle adjacent (right next to) the angle that measures 107˚. As you can see, it is a supplementary angle because both of them form a straight line, or 180˚.
Therefore,
107+x= 180
x= 180-107
x= 73˚
Next, I will find the measure of the angle that is vertical to the one that measures 107˚. Note that angles that are vertical to each other are always identical, or in other words they have the same measure. Hence, the angle "vertical", or opposite to the one that measures 107˚ has to measure 107˚ as well. You can also tell this is true because they look the same.
Now I'll find the measure of the angle vertical to the one that measures 73˚. As we know, vertical angles are identical, so the one vertical to it is 73˚.
Here, I'll solve for angles 1 and 2. Like I said earlier, when a transversal crosses through 2 parallel lines, there will be 2 sets of angles that all have the same measurements.
To solve for angle 1, simply know what angle is right below it, and that is the one that measures 107˚. (If you look at the 2 lines, you will see that both angle sets are essentially duplicates of each other.) Likewise, angle 2 has to be 73˚ because the one under it is also 73˚.
Angle 1: 107˚
Angle 2: 73˚
QUESTION 8:
Again, we have a transversal that passes through 2 parallel lines. One angle measures 95˚. When there are 3 seperate angles along a straight line, the one next to the one with the given measurement will be the same as that one.
So angle 3 is 95˚. To find angle 4, find the angle measurement that's vertical to angle 3, which is 95˚. Now, since that angle and angle 4 are supplementary (both form a straight line which is always 180˚), 95+x= 180.
(x stands for angle 4)
x+95= 180
x= 180-95
x= 85
Angle 4= 85˚.
QUESTION 9:
ANGLE 5: 49˚
When there is a transversal, there are 2 identical pairs of angles. Therefore, angle 5 must be 49˚.
ANGLE 6: 131˚
angle 5 and angle 6 form a straight line which means they are supplementary angles. Therefore, both angles must add up to 180˚. So 49+x= 180
x= 180-49= 131
(x stands for angle 6)

andre is traveling from jeffersonville to springfield. he plans to stop for a break when the distance he has traveled and the distance he has left to travel have a ratio of 3:7. where should andre stop for his break? jeffersonville, J (-15, 2). springfield, S (25, 17)
Answers
Answer:
Andre should stop at (-3 , 6.5)
Step-by-step explanation:
The change in x is from -15 to 25 which is 40 units. 40 x 3/10 = 12 which means Andre moves 12 units right starting from -15 so the x coordinate is -15+12 = -3
The change in y is from 2 to 17 which is 15 units. 15 x 3/10 = 4.5 which means Andre moves 4.5 units up starting from 2 so the y coordinate is 2+4.5 = 6.5.

A Rover driving on the moon’s surface travels at a speed of 60 ft/min. How far will it travel in 90 min?
Answers
Answer:
d =5400 ft
Step-by-step explanation:
d = rt
where d is distance r is rate and t is time
d = 60 ft/ min * 90 min
d =5400 ft
Answer:
5400ft
Step-by-step explanation:
If you are travelling 60ft/min or 60 feet in one minute, you can multiply by 90 minutes to find the number of feet you will travel in that time.
60ft/min * 90min = 5400ft

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.
