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

Answers

Answer 1

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!!

Jim needs to rent a car. A rental company charges $21 per day to rent a car plus $0.80 per mile driven. How many miles can he drive in a day if he wants to spent AT MOST $82. Write an inequality. Show work Or explain how to solve it and then give a solution as an inequality.

Answers

Answer:

Inequality: .80x +21 ≤ 82

Answer: 76.25 miles in total

Step-by-step explanation:

Hi,

An inequality to represent this is .80x +21 ≤ 82

(.80 is the cost per mile and x is the number of miles driven. 21 is the fee that must be paid no matter what and the 82 is the total cost they can pay. We use the ≤ sign to say they can spend less than or equal to 82. The phrase "at most" means we can use the ≤ sign).

Now we solve...

.80x + 21 ≤ 82

Subtract 21 on both sides...

.80x ≤ 61

Now, divide by .80 on both sides...

x ≤ 76.25

He can drive up to 76.25 miles in total

Hope this helps :)

Let H be the height and W be the width of the parallelogram. Then the area of the parallelogram will be given as,

Area of the parallelogram = H × W square units

The figure can be composed of different shapes.

The composed figure is a parallelogram. The dimension of the parallelogram is 10 inches high and 14 inches wide base. Then the area of the parallelogram is calculated as,

A = 10 x 14

A = 140 square inches

The area of the composed figure that is a parallelogram will be 140 square inches.

The parallelogram is made from a rectangle. Thus, the correct option is D.

The length of a rectangle is 3 times its width. If the length were increased by 2 inches and the width by 1 inch, the new perimeter would be 62 inches. What is the width and length of the rectangle? If w represents the width of the rectangle, then which equation could be used to solve for w?
2(4 w + 3) = 62
( w + 1)(3w + 2)=62
2(3 w + 3) = 62

Answers

pretty sure it’s the second option because length would be 3w+2
and width would be w+1 and with area you have to multiply so it would just be the (w+1)(3w+2)

Answer:

     2(4 w + 3) = 62

          width  =7      length = 21

Step-by-step explanation:

For the perimeter you need :

2 times the width     and    2 times the length (length =3w)

so

2(w+1) + 2 (3w+2) =

2w+2 + 6w+4 =

8w +6

you  can factor this by:

2(4w+3)

                      8w +6= 62

                       8W = 56

                      w= 7      l= 21

                    2(7+1)  + 2 (21+2)

                           16 +  46 = 62
