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_)

Every Sunday morning, Opal, Lisa, Talia, and Cora meet for breakfast at the Bagel Shop.
They share the bill equally and each pay $2 toward the tip. The expression 1/4x +2 represents
the amount each friend pays, where z is the amount of the bill before the tip.
The term 1/4x represent the amount each friend pays bill before the tip.
And, The term 2 represent the amount each friend pays towards the tip.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 1/4x + $2
Which represents the amount each friend pays.
Where, x is the amount of the bill before the tip.
Now,
Since, The expression is,
⇒ 1/4x + $2
Where, x is the amount of the bill before the tip.
Hence, We get;
The term 1/4x represent the amount each friend pays bill before the tip.
And, The term 2 represent the amount each friend pays towards the tip.

Drag the answers to match the inequality and the situation it represents.
Answer:
b < 11 = The baby weighs at least 11 pounds.
b > 11 = The box contains more than 11 books.
b < 12 = There are fewer than 12 beetles in a jar.
b > 12 = The building is taller than 12 feet.
Step-by-step explanation:
The baby weighs at least 11 pounds is b < 11 because the baby weighs more than 11 pounds.
The box contains more than 11 books is b > 11 because there are more books in the box than 11.
There are fewer than 12 beetles in a jar is b < 12 because there are less than 12 beetles in a jar.
The building is taller than 12 feet is b > 12 because 12 feet is less than how tall the building is.

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover
1 3/5 doors. How many liters of paint are needed for 1 door?
I need an explanation with the answer and I need it today :)
Answer:
I think it's 1 1/4 liters of paint for one door
Step-by-step explanation:
First you have to turn it to an improper fraction
1.) 1 3/5 = 8/5
Then you have to proportion the fraction with the 2 liters (L=liters)
2.) 2/(8/5)
= 10/8 L
3.) Next you convert the fraction to a mixed number
10/8 L --> 8/8 + 2/8 = 1 1/4 L
