Emily and Andy each go to a hardware store to buy wire.The table shows the relationship between the cost and the length of wire.
Lady_Fox [76]

Answer:

So, Emily will spend,  11.52 unit on wire

and, Andy will spend  18.72 unit on wire.

Step-by-step explanation:

Cost of wire is = \frac {4.80}{120}

                       =  \frac {5.40}{135}

                       = \frac {6.00}{150}

                       = \frac {7.00}{175}  

                        = 0.04 unit/inch

We know that,

 12 inch = 1 foot    and

  1 yard = 3 foot    [Note that unit of a quantity always denoted singular].

So, Emily will spend,

  24 \times 12 \times 0.04 unit

 = 11.52 unit on wire

and, Andy will spend,

  13 \times 3 \times 12 \times 0.04 unit

 = 18.72 unit on wire.

How would a vertical line test that a circle is not function?
AleksAgata [21]

The vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function

This question was not correctly written

Complete Question

Tank A initially contained 124 liters of water. It is then filled with more water at a constant rate of 9 liters per minute. Fill in the blank with the amount of water in liters that is in tank a at the given time

How much water is in the tank

after 4 minutes?

How much water is in the tank after 80 minutes ​?

Answer:

How much water is in the tank

after 4 minutes?

= 160 liters

How much water is in the tank after 80 minutes ?

= 844 liters

Step-by-step explanation:

Tank A initially contained 124 liters of water. It is then filled with more water at a constant rate of 9 liters per minute.

How much water is in the tank

after 4 minutes?

1 minute = 9 liters

4 minutes = x

x = 9 liters × 4

x = 36 liters

The amount of water in the tank after 4 minutes

= 124 liters + 36 liters

= 160 liters

How much water is in the tank after 80 minutes ?

1 minute = 9 liters

80 minutes = x

x = 9 liters × 80

x = 720 liters

The amount of water in the tank after 4 minutes

= 124 liters + 720 liters

= 844 liters
