Step-by-step explanation:

The weight of the whole melon is the sum of the 1¹/₈ pounds given to the neighbor and the 6/8 pounds remaining.

Convert improper to proper:

1¹/₈  = 9/8

In 2001, a company marketed 730,000 units of its product. In 2001 its yearly volume was 50% of its volume for 2004. The 2004 vol
bazaltina [42]

Answer:

4000 units

Step-by-step explanation:

In 2001 the total number of marketed units= 730,000

If this number represents 50% of what was marketed in 2004, then the total number of units marketed in 2004 was:

(100/50)× 730,000=1460000

To get the number for each of the 365 days in 2004 we divide the total for 2004 by 365

1460000/365= 4000 units

8. Suppose y varies directly as x. If y = -4 when x = 32, find x when ys -0.​
Nata [24]

Answer:

x=0

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

in this problem

For x=32, y=-4

Find the value of the constant of proportionality k

k=y/x

substitute

k=-\frac{4}{32}

simplify

k=-\frac{1}{8}

so

The linear equation is

y=-\frac{1}{8}x

Find x when the value of y=0

Remember that

In a proportional relationship <u><em>the line passes through the origin</em></u>

so

If y=0

then

the value of x must be equal to zero

therefore

x=0
