Initially a pool contains 350 gallons of water. A hose is placed in the pool and the water is turned on. The hose adds 5.2 gallons of water per minute. Model the total amount, V, of water in the pool for x, the number of minutes the hose has been on.

Answers

amount in pool=current amount+amount added
amount added=amount added per 1 unit of time times how many units of time

how many units of time=x
amount added per 1 unit of time=5.2 gallons
amount added=5.2x
currrent amount=350
V=350+5.2x

Solve.{3x+y=42x+y=5

Use the linear combination method.

A.) (-3,12)
B.) (-3,13)
C.) (0,4)
D.) (-1,7)

Answers

Answer:

(D)(-1,7)

Step-by-step explanation:

We want to solve for x and y in the simultaneous equation

3x+y=4

2x+y=5

Subtract Equation 2 from Equation 1

x=-1

Substitute x=-1 into any of the equations to solve for x.

3x+y=4

3(-1)+y=4

-3+y=4

y=4+3=7

Therefore: (x,y)=(-1,7)

3x + y = 4
2x + y = 5....multiply by -1
--------------
3x + y = 4
-2x - y = -5 (result of multiplying by -1)
-------------add
x = -1

3x + y = 4
3(-1) + y = 4
-3 + y = 4
y = 4 + 3
y = 7

solution is (-1,7)

Kelly is having a party. She wants to make punch. The recipe forunch uses 3 pints of pineapple juice,5 cups of orange juice, gallon ofade, and 1 quart of apricot nectar.Part AKelly says her recipe will make 20 cups of punch. Is Kelly correct?Explain your answer.

Answers

Answer:

Kelly is wrong and the recipe will make 19 cups of punch.

Step-by-step explanation:

We are given that,

The amount of ingredients in the recipe of punch after converting the units to 'cups' are given by,

Pineapple juice = 3 pints = 6 cups .......................(As 1 pint ≈ 2 cups)

Orange juice = 5 cups

Lemonade = (1)/(4) gallon = 4 cups ...........................(As 1 gallon = 16 cups)

Apricot nectar = 1 quart = 4 cups .........................(As 1 quart = 4 cups)

Then, the total cups of punch = 6 + 5 + 4 + 4 = 19 cups.

Thus, Kelly is wrong and the recipe will make 19 cups of punch.

No she is not because a galloon equals 16 cups, a quart equals 4 cups, and a pint equals 2 cups. So altogether including the other 5 cups, it would be 27 cups.
