A large pool has a faucet to allow water to enter the pool and a drain to allow water to leave the pool.

Each minute, the faucet allows 10 3/4 gallons of water to enter the pool, and the drain allows 12 1/3 gallons to leave the pool.

What is the change in the amount of water in the pool after 112 minutes?

Enter your answer as a simplified mixed number by filling in the boxes.

Answers

The change in the amount of water in the pool is the difference between the amount of water that enters and leaves the pool

Change in volume of water in the pool after 112 minutes is [tex]\underline{-117\frac{1}{3}}[/tex] gallons

Reason:

The given parameters are;

The volume volume of entering the pool = 10 3/4 gallons per minute

The volume of water leaving the pool = 12 1/3 gallons per minute

Required:

The change in the amount of water in the pool after 112 minute

Solution:

The volume of water, V₁, that enters the pool in 112 minute is given as follows;

V₁ = 10 3/4 × 112 = 1,204

The volume of water, that enters the pool, V₁ = 1,204 gallons

The volume of water, V₂, that leaves the pool in 112 minute is given as follows;

V₂ = 12 1/3 × 112 = 1,381[tex].\overline 3[/tex]

The volume of water, that that leaves the pool, V₂ = 1,381[tex].\overline 3[/tex] gallons

The change in the amount of water in the pool after 112 minutes, ΔV, is given as follows;

ΔV = V₁ - V₂

ΔV = 1,204 - 1,381[tex].\overline 3[/tex] = -177[tex].\overline 3[/tex] = -(117 1/3)

Change in volume of water in the pool after 112 minutes, ΔV = [tex]\underline{-117\frac{1}{3}}[/tex] gallons

Answers

Answer:

angle 4 = 115°[vertically opposite angles]

angle 2+ angle 4=180°[linear pair]

angle 2+ 115 = 180°

angle 2 = 180°-115°

angle 2=65°

angle1+angle2+80°=180°[sum of all angles is 180°]

angle1+65°+80°=180°

angle 1 + 140° = 180°

angle 1=180°-140°

angle1 =40°

angle2= angle5[vertically opposite angles]

angle7+angle5+61°+90°=360°[sum of all angles of quadrilateral is 360°]

angle7+ 65°+ 61° +90°=360°

angle7+ 211°=360°

angle7=360°-211°

angle7=149°

angle7+angle6=180°[linear equation]

149°+angle6=180°

angle6=180°-149°

angle6=31°

angle4+angle6+angle3= 180°[by sum of all angles is 180°]

115°+31+angle3=180°

146°+angle3=180°

what does this q equal

Answers

Answer:

30 degrees

Step-by-step explanation:

Since all triangles' angles add up to 180 degrees, you can add the sum of the angles you already know and subtract it from 180.

126+24=150

180-150=30

so angle Q = 30 degrees

the answer to your question, the Q equals 30 degrees.

Instructions-Solve the system of equations. Type in all points of intersection for the two functions and round to the nearest tenth if necessary.
-
f(x) = 5x + 25 - 1
8(x) - - 2x-3

Answers

Answer:

f(x)=5x+25-1

8(x)- -2x-3

=30-1

=8x+6x

=29+14x

43x

The point of intersection of the two functions is (3, 27).

The system of equations is:

f(x) = 5x + 25 - 1 = 5x + 24

g(x) = 2x - 3

To solve this system, we can use the elimination method. We can eliminate the x-term by adding the two equations together.

f(x) + g(x) = 5x + 24 + 2x - 3 = 7x + 21

Solving for x, we get:

x = 21/7 = 3

Now that we know the value of x, we can plug it back into either equation to find the value of y. Let's use the equation for f(x).

f(x) = 5x + 24

f(3) = 5(3) + 24 = 27

Therefore, the point of intersection of the two functions is (3, 27).

To the nearest tenth, the point of intersection is (3.0, 27.0).

A taxi charges a flat rate of $1.75, plus an additional $0.65 per mile. If Erica has at most $10 to spend on the cab ride, how far could she travel? Write an inequality expression that represents the situation and solve! Explain your reasoning! You can copy/paste the needed symbols as needed: ≥ ≤

Answers

Answer:

The inequality expression would be 1.75+0.65x ≥10

She would be able to ride ~12.7 miles or just 12 miles rounding down.

Step-by-step explanation:

Following mx+b, the m value would be 0.65 because it is added per mile.

The 1.75 would be the b value because it is the starting value.

So the equation would look like 1.75+0.65x. To know if the 10 value would be less than or more than, we have to know if 10 is the limit value or starting value. Because 10 is our limit value, we will use greater than or equal to.

To know how many miles Erica could travel, we would have to subtract 1.75

from 10. We would get 8.25. We would then divide 8.25 by 0.65. so the number of miles she can travel is ~12.7 miles or just 12 miles rounding down.

Gatsbys house was still empty when I left the grass on his lawn had grown as long as mine. One of the taxi drivers in the village never took a fare past the entrance gate without stopping for a minute and pointing inside; perhaps it was he who drove Daisy and Gatsby over to East Egg the night of the accident, and perhaps he had made a story about it all his own. 5 I didnt want to hear it and I avoided him when I got off the train. I spent my Saturday nights in New York because those gleaming, dazzling parties of his were with me so vividly that I could still hear the music and the laughter, faint and incessant, from his garden, and the cars going up and down his drive. One night I did hear a material car there, and saw its lights stop at his front steps. But I didnt investigate. 10 Probably it was some final guest who had been away at the ends of the earth and didnt know that the party was over. On the last night, with my trunk packed and my car sold to the grocer, I went over and looked at that huge incoherent failure of a house once more. On the white steps an obscene word, scrawled by some boy with a piece of brick, stood out clearly in the moonlight and I erased it, drawing my shoe raspingly along the stone. Then I wandered down to the beach and sprawled out on the sand. 15 Most of the big shore places were closed now and there were hardly any lights except the shadowy, moving glow of a ferryboat across the Sound. And as the moon rose higher the inessential houses began to melt away until gradually I became aware of the old island here that flowered once for Dutch sailors eyes a fresh, green breast of the new world. Its vanished trees, the trees that had made way for Gatsbys house, had once pandered in whispers to the last and greatest of all human dreams; for a transitory 20 chanted moment man must have held his breath in the presence of this continent, compelled into an aesthetic contemplation he neither understood nor desired, face to face for the last time in history with something commensurate to his capacity for wonder. And as I sat there brooding on the old, unknown world, I thought of Gatsbys wonder when he first picked out the green light at the end of Daisys dock. He had come a long way to this blue lawn, and his dream 25 must have seemed so close that he could hardly fail to grasp it. He did not know that it was already behind him, somewhere back in that vast obscurity beyond the city, where the dark fields of the republic rolled on under the night. Gatsby believed in the green light, the orgastic future that year by year recedes before us. It eluded us then, but thats no matter to-morrow we will run faster, stretch out our arms farther. . . .
