A mountain road is 5 miles long and gains elevation at a constant rate. After 2 miles, the elevation is 5500 feet above sea level. After 4 miles, the elevation is 6200 feet above sea level.
What would be the equation of this line?
Find the elevation of the road at the point where the road begins.
Describe where you would see the point in part (a) on a graph where represents the elevation in feet and represents the distance along the road in miles.
Answer:
I hope this helps
Step-by-step explanation:
The elevation of the road 4800 feet at the beginning and it gains elevation at a constant rate of 350 feet per mile.
A linear equation is in the form:
y = mx + b;
where m is the rate of change, b is the initial value of y and y, x are variables.
Let y represent the elevation of the road after x miles.
After 2 miles, the elevation is 5500 feet above sea level. Hence:
5500 = 2m + b (1)
After 4 miles, the elevation is 6200 feet above sea level. Hence:
6200 = 4m + b (2)
Solving equation 1 and 2 simultaneously gives:
m = 350, b = 4800
The elevation of the road 4800 feet at the beginning and it gains elevation at a constant rate of 350 feet per mile.

Need help guys can you answer this.
Answer:
10h=m or if you not at that math level yet it would times Hx10=M
Step-by-step explanation:
Answer:
m = 9h
Step-by-step explanation:
you can see that in 5 hours she earns 45 dollars
divide 5 hours by 5 and 45 dollars also by 5
you then find that in 1 hour she earns 9 dollars
so in h hours she earns 9 times h
which is h = 9h
but in this case it asks for money so it is m = 9h (h is how much hours she worked)

Identify the percent of change in the alligator population using 5000 as an estimate for the population of the alligator in 1967, and 5 million as an estimate for the present day population. Use your results to explain why alligators aren't considered endangered anymore. (Note the part for the percent proportion is the change in population, and the whole is the initial population in 1967)

What would be the perimeter of an image if a scale factor of 5 was applied?
Answer:
Step-by-step explanation:
So first if it was a scale factor 5 you would multiply it by 5 for each side. So for the side of 8 you would multiply it by 5 which is 40 so that side and the other side across from it would also be 40 units. Then for the next one there is 12 units so you do the same 12x5 is equal to 60 so will the one below it.
Then it would be (40 * 2) + (60 * 2)= 80 + 120= 200
So then the perimeter would be 200 units.

Is 6 a solution to the equation x2 - 4 =5x
Answer:
No.
Step-by-step explanation:
Let's verify that the left-hand-side and -right-hand-side are different, when we replace x by 6:
(6)^2-4=36-4=32
5(6)=30
As 32 is different from 30, then 6 is not a solution of the equation.
Answer:

The number of dollar bills are needed to cover the United States, when 2.5×10^8 dollar bills to cover a square mile area is 9.5×10^¹⁴.
What is the exponent power with base 10?To write the big number in short form, we write them in the positive power of 10.
To write the very small number, we write them in the negative power of 10.
Tyler’s math class found that it would take 2.5×10^8 dollar bills to cover a square mile area.
The surface area of the United States is about 3.8×10^6 square miles.
To find the number of dollar bills are needed to cover the United States, we have to multiply 3.8×10^6 square miles with 2.5×10^8 dollar bills.
Let suppose it needed n dollar bills. Thus,
[tex]n=3.8\times10^6\times2.5\times10^8\\n=3.8\times2.5\times10^6\times10^8[/tex]
When the base is same in multiplication operation, add the power. Thus,
[tex]n=3.8\times2.5\times10^6\times10^8\\n=3.8\times2.5\times10^{6+8}\\n=9.5\times10^{14}[/tex]
Thus, the number of dollar bills are needed to cover the United States, when 2.5×10^8 dollar bills to cover a square mile area is 9.5×10^¹⁴.

Screen-printing a batch of shirts requires 3 minutes per shirt in addition to 16 minutes of initial set-up time. If it takes 31 minutes to screen-print a batch of shirts, how many shirts are in the batch?
Answer:
The 16 comes from the fact that we take 16 minutes to set up
Step-by-step explanation:
Answer:
The answer is 5 shirts per batch.
Step-by-step explanation:
If you subtract 16 from 31 you get 15.
And because you make 1 shirt per 3 mins, you can divide 3 from 15 and that would get you to 5.

The distance of planet Mercury from the Sun is approximately 5.8 ⋅ 107 kilometers, and the distance of planet Venus from the Sun is 1.1 ⋅ 108 kilometers. About how many more kilometers is the distance of Venus from the Sun than the distance of Mercury from the Sun?
5.2 ⋅ 107 kilometers
4.7 ⋅ 108 kilometers
5.2 ⋅ 108 kilometers
5.7 ⋅ 109 kilometers
Answer:
5.2
Step-by-step explanation:
distance(Mercury, Sun) = 5.8 x 10^7
distance(Venus, Sun) = 1.1 x 10^8
distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7
The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.
simply subtract 5.8 from 11.0.
This gives us a result of 5.2 x 10^7.
