Ok so descend means to go down and ascend means going up. With that in mind, you know what operations to use. You start at -170 and then climb up 72 feet. 170-72= 98. Now you drop -88. 98-88=10 go up 40 next 10+40= 50. Lastly, you go up by 50 feet. 50+50=100 which means your current elevation is 100 feet. I hope this helps you :)
The formula for an equation is y=mx+b. M is the slope and B is the y-intercept. Since the slope is -1 and the y-intercept is -6 the equation would be y=-1x-6
Answer: 450
Step-by-step explanation:
You will do 50 times 9, and then you will get 450. You get this answer because you get 50 each day so you will need to multiply 50 times 9 to figure out how much she earns on the ninth day.
Answer: The shorter tour is not possible.
Step-by-step explanation: For this problem, we dont even need to find R and S because we have a lot of information already given to us. On the way up, the boat travels at 25/2mph which translates to 12.5mph. On the way down, the boat travels at 25/1.25mph which translates to 20mph. Since the tour is 20 miles, we can calculate the amount of time that the tour will take. Time up:20/1,25=1.6 hours. Time down:20/20= 1 hour. When we add those up, we get 2.6 hours which is more than the desired 2.5 hours. That is why the shorter tour is not an option.
