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
Left over=1700ft after 5 months of digging
help/
Answer:
Part A answer: 10 2/3 months
Part B answer: No
Step-by-step explanation:
Using what we gathered from the word problem, and the hint, we know that y = distance, x = time, and b = 3200.
3200 is the total number of ft meant for the hole to be dug. If we've been digging for 5 months, and we have 1700 ft yet to be dug, then after 5 months we have dug (3200 - 1700 =) 1500 ft in 5 months.
-1500 ft/5 months = 300 ft/month
-Digging the final 1700 ft will take 5 2/3 months
^ Using this information, we know that the total number of months it takes to dig the entirety of the tunnel is 10 2/3
In the second part of the problem, we're asked to determine whether or not a deadline of August 2021 was enough time to complete the 10 2/3 month-long project if the digging began in December of 2020.
If said project commenced in December 2020, and the deadline was August 2021, then there would be 1, 2, 3, 4, 5, 6, 7, 8... Roughly 8 1/2 months to complete the tunnel. 10 2/3 months is > (greater than) 8 1/2 months. So, no. That start-to-finish deadline would not be enough time.
Good luck!!
10d + 20 = 100 pls answer quick
Let's solve your equation step-by-step.
10d+20=100
Step 1: Subtract 20 from both sides.
10d+20−20=100−20
10d=80
Step 2: Divide both sides by 10.
10d
/10= 80/10
so d= 80
forgot the zero

Answer:
A, C, and D
Step-by-step explanation:
A is one answer because if you were to add 3.9 and the value of ?, you would get 8.6. The same would apply to C, just backwards because it is 8.6 = 3.9 + ?. Finally, D is another answer because if you subtract 3.9 from 8.6, you will get the value of ?.

The following cards are used in a game. If each of the cards is turned over and shuffled, then how much of a greater chance is there in drawing a spade over drawing a 7?
Answer:
1/6 of a chance aka 16.666?%
Step-by-step explanation:
The probability of drawing a card with number 7 is 0.166.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
From the given set of cards,
Total number of cards =6
Number of spades = 3
Number of card with number 7 on it = 1
Probability of drawing a 7 = 1/6
= 0.166
Therefore, the probability of drawing a card with number 7 is 0.166.

c.962.51 in^3
step-by-step explanation:
so first we have to find the radius
in order to find the radius we divide 12 1/4÷2
which equals 6.125, now we have our radius
now we need to set up the formula
v=4/3πr^3
v=4/3π6.125^3
v=962.51

At this weekend’s football game, 20 out of the first 50 people who entered the field were not wearing hats. If this sample is representative of the 300 people attending the game, about how many of them will probably NOT be wearing hats? Show all work and justify your answer.
Answer:
180 People will wear Hats
Step-by-step explanation:
If there are 30 people that wear hats out of 50 we extrapolate that data meaning we just multiply both till we get the disired number of 300, so 50x6 = 300, so 30x6= 180

According to this law, an object at rest (like the egg sitting on the tube) should stay that way unless a force pushes or pulls it (your hand striking the pie pan). ...

What is the sample in this example.
Answer:
The sample size is 60.
