Answer:

The correct ordered pairs are:

{(1, 6.7), (2, 6.4), (3, 6.1)}

Option A is correct.

Step-by-step explanation:

A watering can dispenses water at the rate = 0.3 gallon per minute

The original volume of water in the can = 7 gallons.

Which set of ordered pairs shows the volume of water in the can in gallons (y), as a function of time in minutes (x), from the first minute after the can starts dispensing water?

First making the function:

The the volume of water in the can in gallons is represented by y and  time in minutes is represented by x. Initially the volume is 7 gallons, after than water dispense at rate of 0.3 gallon per minute so, the function will be:

y=7-0.3(x)

Now, putting values to find ordered pairs

So, when time is 1 minute i.e x = 1

y=7-0.3(1)

y=7-0.3

y=6.7

So, when x=1, y=6.7 the ordered pair is: (1,6.7)

when time is 2 minutes i.e x = 2

y=7-0.3(2)

y=7-0.6

y=6.4

So, when x=2, y=6.4 the ordered pair is: (2,6.4)

when time is 3 minutes i.e x = 3

y=7-0.3(3)

y=7-0.9

y=6.1

So, when x=3, y=6.1 the ordered pair is: (3,6.1)

So, the correct ordered pairs are:

{(1, 6.7), (2, 6.4), (3, 6.1)}

Option A is correct.

Answer:

k = 4/3

Step-by-step explanation:

Formula for k: y/x

If y = 4 and x = 3, then we use the formula (y/x) in order to find the constant of proportionality:

k = 4/3

Answer:D

Step-by-step explanation: a function has only one output value for each input value

Answer:

2 - 18w or -18w + 2

Step-by-step explanation:

6(-3w + 1/3)

Multiply using distrubutive property

-18w + 6(1/3)

Multiply 6 * 1/3 to get 6/3 or 2

-18w + 2

This is optional, but put the variable term on the right

2 + (-18w)

2 - 18w

PetSmart is offering the best deal

Step-by-step explanation

For Gristede's we get 18 and divide it by 12 which would give us $1.50 per can

For PetSmart we get 26 and divide it by 20 which would give us $1.30 per can

Answer:

5/4 and - 1/4

Step-by-step explanation:

16n^2-10n-5=6n

16n^2-16n-5=0

(4n+1)(4n-5)

4n=-1        4n=5

n= -1/4  n= 5/4

Step-by-step explanation:

circumference C=2*3.14*r

C=2*3.14*18m=113.04 m

Answer:

113.04 meters.

Step-by-step explanation:

Use the formula

2 times pi times r

r=radius of the circle

or Pi times D

d= diameter of the circle.

The radius is 18 meters.

So, do 2 times 18 times pi.

Answer:

y= 115

Step-by-step explanation:

Step one:'

given data

The total charge for this cabin is represented by the equation

[tex]y=4x+35[/tex]

we are told that  y represents the total cost and x represents the length of stay in days

Required:

the value of y when x= 20

Step two:

substitute

[tex]y=4(20)+35\\\\y=80+35\\\\y=115[/tex]

Answer:

∠B = 60°

Step-by-step explanation:

They are supplementary angles, which means they add up to 180°.

∠B + ∠A = 180

? + 120 = 180

? = 180 - 120

? = 60°

Step-by-step explanation:

you can do it using the formula of ratio

Answer:

large dogs = 32

Step-by-step explanation:

small dogs to large dogs = 4: 3

total ratio = 7

large dogs = 4/7

total dogs = 56

large dogs = 4 x 56

                     7

large dogs = 32

Answer:

  Only one

Step-by-step explanation:

Taking the question at face value, the equation simplifies to ...

  y(6 -3) -7 = 1

  y = 8/3 . . . . . . .divide by 3

There is exactly one solution.

okay okay 123

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

175-87=88 so 88 is where the dot needs to be located so we have option A and option B

For ≤ and ≥ , use a closed dot

For > and < , use a open dot

she said AT LEAST 175

so we would use a closed dot

Answer:

9 dollars

Step-by-step explanation:

let x be per mile

the equation for solving this would be 0.5x + 3(flat fee)=amount you have to pay

The x is 12 since you have to go 12 miles

0.5(12)+3=amount you have to pay

6+3=amount you have to pay

$9=mount you have to pay
