HURRY!! A climber is on a hike. After 2 hours he is at an altitude of 400 feet. After 6 hours he is at an altitude of 700 feet. What is the rate of change.
Answers
Answer:
175ft an hour
Step-by-step explanation: lets say t=hours
so 2t=400ft and 6t=700ft
the difference between hours is 4 because 6-4=2
so we would multiply 4 by ?
to get the missing # you would have to multiple 4 by numbers between 170 and 190 because anything under 170 is no where near 175 and anything above 190 is way off 175. Answer is 175ft per hour
Answer:
total distance =700+400ft
time =2+8 =10hour
rate =distance/time=1100/10=110 ft/hour
since he stops two times
rate of change =110/2=75ft/hour

It takes 12 people to mow Richard Richerson's lawn. If his lawn is 600,000 square yards, what is the average number of square yards each person will mow?
Answers
Answer:
each person will mow 50,000 square yards
Step-by-step explanation:
Given;
mow Richard Richerson's lawn = 600,000 square yards
number of people, = 12 people
The average number of square yards each person will mow is given by;
= 600,000 square yards / 12 people
= 50,000 square yards / person
Therefore, each person will mow 50,000 square yards
A hiker begins at sea level and descends 25 feet every minute. How long will it take to get to an elevation of -750 feet?
Answers
Answer:
it would take about 7 1/2 minutes.
Step-by-step explanation:
please give brainliest
Answer:
30 minutes
Step-by-step explanation:
The hiker starts at sea level or 0 feet. He descends 25 feet every minute. This can be written in an equation as so, 0 acting as the starting point, f being feet, and m being minutes:
f = 0 - 25m
This simplifies to:
f = - 25m
We can substitute f in for -750
-750 = - 25m
Now, we divide by - 25 by both sides of the equation
-750 ÷ - 25 = 750 ÷ 25 = 30
30 = m
It would take 30 minutes for the hiker to get to - 750 feet in elevation.

continuousdistance traveled by walkingStep-by-step explanation:
You can draw the graph without lifting your pencil, so it is "continuous."
Rows, drinks, and books are all things that are counted. That is, their number takes on discrete values.
Time, on the other hand, is continuous--able to take on any value.
The graph best models distance as a function of time.

What is the least common multiple of 6 and 8?
Answers
Answer:
2
Step-by-step explanation:
correct answers only pls.
Answers
Explanation: The number marked by the dot is 1.25. To convert decimals to fractions, think of it as a percent. 1.25% is like 125% (out of 100%) so that would be 125/100. Then divide by GCD (greatest common divider). GCD must be a multiple of both 125 and 100. The GCD in this case is 25. So divide numerator (125) and denominator (100) by 25 to get 5/4. Hope this helps :)

80m of cloth are required to make 36 shirts. How many cloth required to make 45 shirts?
Answers
Answer:
80m --------> 36 shirts
x m ----------> 45 shirts
Thus by the unitary method, the value of x will be;
36 × x = 80 × 45
x = 80 × 9 × 5 / 36
x = 80×5/4
x = 20 × 5
x = 100 shirts.
Answer:
100m
Step-by-step explanation:
80/36= takes 2 2/9 or 20/9 to make one shirt
20/9*45 shirts=100m
