Answer:
19 kilometers
Step-by-step explanation:
2.5 kilometers + 7kilometers
= 9.5 kilometers
+ the additional 9.5 for the trip down
=19 kilometers in total
Stacey total distance for climbing was 16.5 km
Stacey started 2.5 km up the cliff so this 2.5km is not counted as she started at that point.
She then climbed 7 km up the cliff.
After that she climbs back down to the bottom of the cliff. This time she climbs both the 7km she climbed previously, and the 2.5km she hadn't climbed before.
Tracy total climbing distance is:
= Distance climbed up + Distance climbed down
= 7 + ( 7 + 2.5)
= 7 + 9.5
= 16.5 km
In conclusion, Stacey climbed 16.5 km in total.

Answer:
<2 ≅<4 with reason of vertical angle theorem.
Step-by-step explanation:
The vertical angle theorem states that two opposite (non-adjacent) angles formed by 2 intersecting lines have equal measure. In this problem, we are given that the angles are vertical angles. So the statement is that <2 ≅<4 with reason of vertical angle theorem.

8x8= 64, 64-3= 61. 7x61= 427-8= 419
what is the slope or the line going through (0,0) (6,8) A: -6/8 B: -3/4 C: 3/4 D: 8/6
Start at (0,0). To get to the other point, you must move up 8 units and move to the right 6 units.
slope = rise/run = (change in y)/(change in x) = 8/6
Or you could use the slope formula
m = (y2-y1)/(x2-x1)
m = (8-0)/(6-0)
m = 8/6
Normally I would reduce, but your teacher has decided not to.
8/6 reduces to 4/3 when you divide both parts by 2.

Answer:
You meant 1 1/2. Answer : Y intercept
Step-by-step explanation:
The slope of the line on the graph as per the given scenario is 2.
What is Graph?In mathematics, a graph is a visual representation of a set of data or mathematical relationships.
Graphs are used to show the relationship between two or more variables and can be represented in a variety of formats, including line graphs, bar graphs, scatter plots, and more.
To find the slope of a line, we need to determine how much the y-value changes for every 1-unit increase in the x-value. Looking at the graph, we can see that the line passes through the points (1, 2) and (2, 4).
To find the slope, we can use the slope formula:
slope = (change in y) / (change in x)
If we let (x1, y1) = (1, 2) and (x2, y2) = (2, 4), then the slope is:
slope = (y2 - y1) / (x2 - x1)
slope = (4 - 2) / (2 - 1)
slope = 2
Therefore, the slope of the line on the graph is 2.

Andy's phone plan charges $0.45 per text message plus a $20 monthly fee. Jeff's plan charges $0.20 a text plus an additional $35 monthly fee. Which equation can be used to determine when the phone plans will cost the same based on the number of texts?
Answer:
20+0.45x=35+0.20x
Step-by-step explanation:
From the information given, you can say that Andy's plan cost would be equal to Jeff's plan cost and then solve for the number of text to find when the phone plans will cost the same:
20+0.45x=35+0.20x, where x is the number of texts
Now, you can solve for x:
0.45x-0.20x=35-20
0.25x=15
x=15/0.25
x=60
According to this, the equation that can be used to determine when the phone plans will cost the same based on the number of texts is 20+0.45x=35+0.20x.

O
Answer:
A
Step-by-step explanation:
The coach will most likely count this as an expense and will want to overestimate so that he is certain to have all the golf balls for his lessons. If he underestimates, he will not be able to have all his balls.
A. It is better to overestimate to make sure the coach has enough money to buy the golf balls.
What is over and under estimating ?Over estimating is when we set a higher amount than we need in case of price increase and the item is a must buy.
Underestimating when we set a lower amount than needed when money is of more concern and the item is not a must buy.
According to the given question At the beginning of the season, a golf coach buys 118 sleeves of golf balls. Each sleeve costs $8.
It is always better to overestimate and if some amount remains then it can be used later.
So, It is better to overestimate to make sure the coach has enough money to buy the golf balls to continue his lessons without any interruption underestimating will lead to less golf balls and interrupted golf sessions.
