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!!
Blake has a garden in his backyard. He picked 44 tomatoes from 4 tomato plants. What is the ratio of tomato plants to tomatoes picked?
A.
11:1
B.
1:4
C.
1:11
D.
4:1
Answer:
C
Step-by-step explanation:
For every 1 plant, he picks 11 tomatoes off. So the ratio is 1:11. And since there are 4 plants, and 11 tomatoes are being picked off of each, 4x11 = 44.
Answer:
The answer is C.

30.4 + 2.128(7%) rounds up to about =$32.53
your answer is B
Step-by-step explanation:
Answer:
the answer is (C)
Step-by-step explanation:
20% - 7% = 13%
38.00 * (13/100) = 38.00 * 0.13 = 4.94 discount
38.00 - 4.94 = $33.06

I DONNT UNDDERSTAND THIS AT ALL
Answer:
Here's exactly what I would write:
a = Sandy cupcakes, b= Sandy gummy bears, c = Sandy brownies, d = Nina cupcakes, e = Nina gummy bears, f = Nina brownies
a = 4d
b = 3e
c = 2f
Expression for Sandy: 4d + 3e + 2f
Expression for Sandy and Nina: 5d + 4e + 2f
Step-by-step explanation:
This is a terrible question that makes people feel frustrated. I'm sorry.
a = Sandy cupcakes, b= Sandy gummy bears, c = Sandy brownies,
d = Nina cupcakes, e = Nina gummy bears, f = Nina brownies
Sandy has 4 times the number of cupcakes as Nina: a = 4d
Sandy has 3 times the number of gummy bears as Nina: b = 3e
Sandy has 2 times the number of brownies as Nina: c = 2f
An expression for how many desserts Sandy is bringing: a + b + c
An expression that could be used for how many desserts Sandy and Nina are bringing together: a + b + c + d + e + f, but I think they want you to substitute the equivalent values like above (a = 4d)
Sandy: 4d + 3e + 2f
Sandy and Nina: 5d + 4e + 2f
because 4d + 3e + 2f + d + e + f = 5d + 4e + 2f
I'm sorry I don't have a simpler way to explain this. It's a painful question. I will answer any questions you have.
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

Convert 9432000 Milliliters to Liters. Show ALL work and don't forgot the units.
Answer: 9,432 L
To convert 9,432,000, divide by 1,000. Let's explain before we divide.
Look at the zeros in 9,432,000, then look at 1,000. What do they have in common? Zeros. Both numbers have 3 zeros. But what would happen if we divide it by 1,000? Let's figure it out now.
1. Divide 9,432,000 by 1,000.
9,432,000 ÷ 1,000 = 9,432Notice how the zeros were gone when we divided it by 1,000, because we're reducing it by 1,000.
Hence, 9,432 L is the answer.
