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!!

Answer:
(7) 1482 in³
(8) 216 yd³
Step-by-step explanation:
Formulas
Volume of prism
= base × height/length
Area of parallelogram
= base × height
Area of trapezium
= (upper base + lower base) × height ÷ 2
(7)
Area of the base = 19×6
= 114 in²
Length = 13 in
Volume = 144×13
= 1482 in³
(8)
Area of the base = (11+7)×12÷2
= 108 yd²
Length = 2 yd
Volume = 108×2
= 216 yd³
Answer:

Answer:
1) x: small #; y: large #
4y = 7x
x + y = 22
----------------
-7x + 4y = 0
x + y = 22
---multiply the second equation by -4------
-7x + 4y = 0
-4x - 4y = -88
----solve------
-11x = -88
x = 8
---substitute with any of the equation above i chose the very first one------
4y = 7(8)
4y = 56
y = 14
x = 8; y = 14
2) x = small #; y = large #
y - x = 15
5x = y - 9
----after rearranging, solve-----
-x + y = 15
5x - y = -9
-4x = 6
x = -1.5
--------substitute--------
-(-1.5) + y = 15
1.5 + y = 15
y = 13.5
x = -1.5; y = 13.5
3) x = lemon cream; y = fudge cookie
3x + 2y = 400
2x + 3y = 425
----multiply the first equation by -2, multiply the second equation by 3------
-6x - 4y = -800
6x + 9y = 1275
----solve------
5y = 475
y = 95
--------substitute--------
3x + 2(95) = 400
3x + 190 = 400
3x = 210
x = 70
x = 70; y = 95

A specific shade of red nail polish requires 7 parts red to 2 parts yellow. A mixture contains 35 quarts or red and 8 quarts of yellow. How can you fix the mixture to make the correct shade of red?
Answer: add 2 more yellow
Step-by-step explanation:
use the ratio 7 to 2 to solve for 35 to x
[tex]\frac{7}{2} =\frac{35}{x} \\70=7x\\x=10[/tex]
for 35 quarts of red, you will need 10 quarts of yellow to keep the ration proportional. Since it has 8 parts yellow, you need to add 2 more yellow

Hello!
A function will be increasing if the y values are increasing (since this is a function, this will pass the vertical line test, meaning that it is increasing if the y values are increasing).
On interval 1, the function is not increasing since the y value stays constant.
On interval 2, the function is increasing because the y values are increasing.
On interval 3, the function decreases because the y values are decreasing.
On interval 4, the function increases again.
On interval 5, the function stays the same because of its constant y value.
To reiterate, on intervals 2 and 4, the function is increasing.
Hope this helps!
