Elza [17]

Answer:

The unit rate is $8.89 /ft².

Step-by-step explanation:

Given:

$160 for 18ft².

So, by dividing with 18

\frac{160}{18} we get 8.888.

Now, round to nearest hundredth for $8.888 is $8.89.

Therefore, the unit rate is $8.89 /ft².

The owner of a grocery store finds she can sell about 982 gallons of milk in a week if she prices it at $2.99 per gallon. If she
julia-pushkina [17]

Answer:

  • g = -1110p +4300.9
  • 804 gallons

Step-by-step explanation:

a) Price is the independent variable, so the data we are given can be written as ...

  (price, gallons) = (2.99, 982) and (2.79, 1204)

Using the 2-point form of the equation for a line, we have ...

  g = (g2 -g1)/(p2 -p1)(p -p1) +g1

  g = (1204 -982)/(2.79 -2.99)(p -2.99) +982

  g = -1110(p -2.99) +982 = -1110p +4300.9

  g = -1110p +4300.9

__

b) When p = 3.15, the predicted sales volume is ...

  g = -1110(3.15) +4300.9 = 804.4

Weekly sales are predicted to be 804 gallons at a price of $3.15.

A scale drawing of a bedroom is shown below. The scale is 1 : 30.
ladessa [460]

Answer: 75 feet²

Step-by-step explanation:

     The scale means that for every one unit in the scale drawing, it is 30 units in the actual room. We will convert the dimensions using proportions.

\frac{1}{3} =\frac{30}{x}

x = 90

-

\frac{1}{4} =\frac{30}{x}

x = 120

   The area of a rectangle can be found by multiplying the length by the width:

A = L * W

A = 90 * 120

A = 10,800 inches²

 To get this into square feet, we will divide by 144. Why? There are 12 inches in a foot. 12 times 12 is 144.

10,800 inches² / 144 = 75 feet²

           The area of the room, in square feet, is 75 feet².
