1/2 because 2*2*2 equals 8 so all you do is put it in fraction form. 1/2*1/2*1/2= 1/8

An advertiser goes to a printer and is charged $73 for 100 copies of one flyer and $82 for 400 copies of a similar flyer. Assumi

USPshnik [31]

Answer:

y = 0.03x + 70

Slope here represents the variation in the charges with the change in the number of flyers

Positive slope means that the cost is increasing with increase in number of flyers

Step-by-step explanation:

Given:

for 100 copies advertiser is charged = $73

For 400 copies advertiser is charged = $82

Now,

here the charge is a function of number of flyers

we have the general line equation for a linear relationship as:

y = mx + c

here m is the slope

c is the constant

for the first case we have

y = $73

x = 100

thus,

73 = 100m + c ...........(1)

for the second case, we have

y = $82

x = 400

thus,

82 = 400m + c ...........(2)

subtracting (1) from (2)

82 = 400m + c

- ( 73 = 100m + c )

==================

9 = 300m + 0

m = 0.03

substituting the value of slope in equation (1)

73 = 100 × 0.03 + c

73 = 3 + c

c = 70

Hence,

the equation is y = 0.03x + 70

here y is amount charged and x are the number of flyers.

Slope here represents the variation in the charges with the change in the number of flyers

Positive slope means that the cost is increasing with increase in number of flyers

Whitepunk [10]

Answer: The greatest number of rows Li Na can plant is 9.

Step-by-step explanation:

Given: Li Na is going to plant 63 tomato plants and 81 rhubarb plants.

Li Na would like to plant the plants in rows where each row has the same number of tomato plants and each row has the same number of rhubarb plants.

To find the greatest number of rows Li Na can plant, we need to find the GCF of 63 and 81.

Since , $63=7\times9\ and\ 81=8\times9$

Clearly, GCF(63,81)=9

Therefore, the greatest number of rows Li Na can plant is 9.

Answer:

D) 130 workers

Step-by-step explanation:

We have the equation, y = 2x + 40, and y, 300 (since the y-coordinate represents the # of bottles made), so we can solve for x, the number of workers needed.

Substitute: 300 = 2x + 40

Subtract: 260 = 2x

Divide: x = 130

Since x = 130 when y = 300, 130 workers are required to make 300 bottles in a day.
