Answer:

a. $ 0.8

b. 1.25 meters.

Step-by-step explanation:

Given equation that represents the price p (in dollars) of a piece of nylon rope having length L meters,

p=0.8L

a. If L = 1 meter,

The cost of the rope would be,

p=0.8(1) = \$ 0.8

b. if p = $ 1.00,

\implies 1 = 0.8L

\implies L=\frac{1}{0.8}=1.25

Thus, the length of the rope would be 1.25 meters.

<h3>Answer:</h3>

(a) $0.80

(b) 1.25 m

<h3>Step-by-step explanation:</h3>

(a) Put 1 where L is, and evaluate the equation.

... p = 0.8·1 = 0.8

The cost for 1 meter of rope is $0.80.

(b) Put 1 where p is and solve for L.

... 1 = 0.8L

... 1/0.8 = L = 1.25

The length of rope that costs $1 is 1.25 meters.

In a function, y varies inversely with x. The consistent of variation is 4. Which table could represent the function?
lianna [129]

Answer:

none of the tables shown

Step-by-step explanation:

Inverse variation is

xy = k where k is the constant

xy = 4

in the top table

-2*2 = -4 so it cannot be the first table

In the middle table

-2 * -8 = 16  so it is not the middle table

In the bottom table

-2 *4 = -8 so it is not the bottom table

There must be a table not shown

Answer is 19/60. The gcf of both numbers is 5. So divide both top and bottom by 5
95 divided by 5 is 19
300 divided by 5 is 60
19/60 can't be divided any further so that is the answer
