It takes Rick, traveling 36mph, 40 minutes longer to go a certain distance than it takes Evelyn traveling at 84mph. Find the distance traveled
d = r · t and we know that the distance is the same.
Let x = time it takes Evelyn (in hours, since the rate is mph).
Evelyn's distance is 84x.
Rick's distance is 36·(x+2/3) since 40 minutes longer is 2/3 of an hour longer
84x = 36(x+2/3)
84x = 36x + 24
48x = 24
x = 1/2
So it takes Evelyn 1/2 an hour, meaning the distance is 84(1/2) = 42 miles
To confirm this, it would take Rick 42/36 hours or 1 and 1/6 hours. That's 70 minutes, which is 40 minutes longer than Evelyn's 1/2 hour trip.
The distance is 42 miles.
My name is Pauley the Parrot and I have a dilemma. Blackbeard found a
chest full of gold and he wanted to divide it evenly among the crew. The
chest weighed 12 pounds because it was filled to the top with gold. There
are 24 crew members (including myself and Blackbeard) on the boat. I told
him that if he gave each crew member 2 lbs. of gold there would be enough
to go around. Blackbeard said that he could give each crew member { lb of
gold and there would be enough to go around.
Can you help us figure out who is correct? Make sure to explain who was
correct, and why the other person was incorrect. Maybe, I can split my
earnings with you!
Thank you!

A new company president is said to have caused the company "to do a 180." Before the new president, the company was losing 10,000 per month .What is the company most likely doing under the new president?
Answer:
Earning 10,000 per month.
Step-by-step explanation:
Since a "180" usually refers to an opposite, the opposite of "losing 10,000 per month" would happen.
So, the company would be earning money instead of losing money.
The roots of the quadratic function describing the relationship between number of products
produced and overall profit margin are x = 0 and 36. The vertex is a minimum at (18, -35) .
The company actually loses money on their first few products as it costs them more to make
them, but once they hit items they break even again. The worst case scenario is that
they produce items, as they will have a profit of
dollars.

The first root tells us that the profit will be 0 when
Using quadratic function concepts, it is found that the the spaces are filled by the bold numbers below:
Once they hit 36 items they break even againThe worst case scenario is that they produce 18 items, as they will have a profit of -35 dollars.The first root tells us that the profit will be 0 when 0 products are sold.The function has roots at x = 0 and x = 36, and the vertex is a minimum, hence, it is an increasing function, that is:
[tex]x > 0, f(x) > 0[/tex]: Not important in the context of the problem.[tex]0 < x < 36, f(x) < 0[/tex]: Negative profit when between 0 and 36 items are produced.[tex]x > 36, f(x) > 0[/tex]: Positive profit when more than 36 items are produced, x = 36 is the break-even point.Hence, once they hit 36 items they break even again.
The minimum point is (18,-35), hence:
The worst case scenario is that they produce 18 items, as they will have a profit of -35 dollars.[tex]f(0) = 0[/tex], hence the first root tells us that the profit will be 0 when 0 products are sold.

One antifreeze solution is 32% alcohol and another is 16% alcohol. How much of each mixture should be added to make 48L a solution that is 27% alcohol ?
Answer:
33L of 32%
15L of 16%
Step-by-step explanation:
x is the amount of 32% the remainder is 16%, together they make 48 of 27%
32x + 16(48 - x) = 27(48)
distribute
32x + 768 - 16x = 1,296
combine like terms
16x = 528
Divide both sides by 16
x = 33L of 32%
48 - x = 15L of 16%
Between a and b is 10 between a and c 6 these are for the small triangle
between r and q is m and between q and s is 9
help me find m
I WILL MARK BRAINEST
Answer:
m=15
Step-by-step explanation:
since side QS is 9 and side AC is 6 which is 1.5 times bigger so there is a dilation of 1.5 meaning all sides are 1.5 times bigger on the right triangle than the left triangle. Side AB is 10 so 1.5 times 10 is 15 so m=15

Answer:
x = 3Sides are 6, 8 and 10Step-by-step explanation:
Use Pythagorean to find the value of x:
c² = a² + b²Consider:
a = x + 3, b = 3x - 1, c = 4x - 2Substitute and solve for x:
(4x - 2)² = (x + 3)² + (3x - 1)²16x² - 16x + 4 = x² + 6x + 9 + 9x² - 6x + 116x² - 10x² - 16x + 4 - 10 = 06x² - 16x - 6 = 03x² - 8x - 3 = 03x² - 9x + x - 3 = 03x(x - 3) + (x - 3) = 0(x - 3)(3x + 1) = 0x - 3 = 0, 3x + 1 = 0x = 3, x = - 1/3Positive root is accepted only.
Sides of the triangle:
a = x + 3 = 3 + 3 = 6b = 3x - 1 = 3*3 - 1 = 8c = 4x - 2 = 4*3 - 2 = 10A hotel has number of meeting rooms m available for events each meeting room. Has 325 chairs write equation to represent c the total number of chairs in all of the meeting rooms at the hotel

1) 5/12 = 35/ n
2) n/ 52 = 180/ 120
3) 18/n = 21/28
4) n/4 = 24/6
5) 10/16 = n/56
Bonjour,
1) 5/12 = 35/ n
(5/12) /35 = n
5/12 * 1/35 = n
5/420 =n
1/84 =n
2) n/ 52 = 180/ 120
n= (180*52)/120
n=9 360/120 = 936/12 = 78
3) 18/n = 21/28
n = (21/28)/18
n = 21/28 * 1/18
n= 21/504 = 7/168= 1/24
4) n/4 = 24/6
n= 24/6 * 4
n= 96/6 =16
5) 10/16 = n/56
n= 10/16 * 56
n= 560/16
n= 35

iii) ∠AOE + ∠DOE + ∠DOB = 180 {Straight line angles}
67 + ∠DOE + 100 = 180
∠DOE = 180 - 167
∠DOE = 13°
ii) ∠BOC = ∠AOD {Vertically opposite angles}
∠BOC = ∠AOE + ∠DOE
= 67 + 13
∠BOC = 80°
i) ∠AOC = ∠BOD

A sprinter finished a 100-meter race in a time of 12.63 seconds.
If the sprinter were able to keep the same rate of speed, how long
would it take him to complete the 10,000-meter race?
Answer:
1263 seconds
Step-by-step explanation:
100 meters = 12.63 seconds
multiply both sides by 100 since
100*100= 10,000 meters
12.63*100= 1263 seconds
