Task:
Engineers are digging a 3200-foot-long tunnel at a constant rate. After 5 months, the engineers still need to dig 1700 feet to finish the project. How much time does it take to complete the tunnel from start to finish?
Will the engineers have enough time if the project was started in December 2020 and the deadline to finish the project was in August 2021? Please explain your answer for yes or no.
Hint:
y=mx+b (slope-intercept form)
x=time
y=distance
b=3200
Start & Finish: ??
Total length=3200ft
Answer:
318 days or 10.6 months,
No, because the time between august and december is 8 months and it would take 10 to complete the tunnel
Step-by-step explanation:
start by determining the slope:
subtract the remaining distance from the total distance to determine distance so far, then divide by time.
m = (3200 - 1700)/5
m = 1500/5
m = 300
y = mx + b
Plug in to solve for x.
3200 = 300x + 0
3200 = 300x
divide y by m. This is x. (this is known as inverse operation if you didnt know already.)
3200 = 300(10.6_)
1)What if you have two equations equal to y? How do you solve for x?
2)If you need to solve for a variable to substitute, what is your first step?
3)What does it mean to substitute for a value?
Answer:
Step-by-step explanation:
If you have two equations for y, eliminate y by setting these two equations equal to one another. Solve the resulting equation for x. Then substitute your x value into one of the equations for y. Write your solution as (x, y).
2) If you need to solve for a variable to substitute, what is your first step? Example: If you have two equations for y, eliminate y by setting the two equations equal to each other. This decides for you that you must solve for x.
3) What does it mean to substitute for a value? Example: If you have y = 3x and 2x + y = 17, replace y in the second equation with 3x. This eliminates y and allows you to solve for x.
what is the area of the figure in square inches
Answer:
[tex]78in.^{2}[/tex]
Step-by-step explanation:
Area of 2 parallelograms = 2(bh)
= 2(13 x (6 ÷ 2))
= 2(13 x 3)
= 2 x 39
= [tex]78in.^{2}[/tex]
