Answer:

the fox moves mn times as fast as the squirrel

Step-by-step explanation:

the easiest way to do problems like this is by using hypothetical values that make sense (it's best to avoid 0, 1, and 2)

we'll say that n = 3 and m = 4

so if the squirrel moves at <em>s</em> pace, then the rabbit moves at <em>ns</em>, or <em>3s.</em>

if the fox moves at m (4) times the rabbit's pace (3s), then it moves at <em>4(3s)</em>

then just switch out the numbers for their variables, giving you <em>m(ns) </em>

remember that s simply represents the squirrel's pace, we cannot replace it with a number in this case, so switch it with the idea/value it represents

and there you go, mn times the squirrel's pace

Fabric is sold by the yard and many fabrics are 48" wide (4feet). Designers calculate the square feet needed for a garment in or
Natali5045456 [20]

Answer:

How many yards of material does the designer need for the 6 skirts? = 12

How much will ALL the fabric cost? = $150.84

What is the cost of the fabric of ONE skirt? = $12.57

Step-by-step explanation:

How many yards of material does the designer need for the 6 skirts?

First, it says that the yard is 48" wide aka 4 feet. But since it's asking for a total of 6 skirts, you multiply the yard by the number of skirts. Let's try to multiply 48 with 6.

  48

<u>x   6</u>

288

So it will be 288 yards of material but we need to multiply 4 with 6.

  4

<u>x 6</u>

24

So as you can see, 24 is 12 times as many as 288.

If you multiply 24 with 12, you will get the result of 288.

So the answer is 12 yards of material.

-----------------------------------------------------------------------------------------------------------------

How much will ALL the fabric cost?

First, it says that the cost of the fabric is $12.57 per yard.

So, since we got our answer as 12 for our first question, we gotta multiply $12.57 with 12.

    12.57

<u>x        12</u>

 150.84

So the answer is $150.84.

-----------------------------------------------------------------------------------------------------------------

What is the cost of the fabric for ONE skirt?

First, again we check that it's $12.57 per yard.

So, if it's for only one skirt, it will be $12.57.

It says that the fabric cost $12.57 and for one skirt.

If y varies inversely as x and y= 2/5 when x= 2, find y when x= 1
Alik [6]

Answer:

y = 4/5

Step-by-step explanation:

Since, y varies inversely as x.

\therefore \: y  =  \frac{k}{x}  \\ (k = constant \: of \: proportionality) \\  \therefore \: xy = k...(1) \\ plug \: y =  \frac{2}{5}  \: and \: x = 2 \: in \: (1) \\  2\times \frac{2}{5}   = k \\  \implies \: k =  \frac{4}{5}  \\ substituting \: k=  \frac{4}{5}  \: in \: (1) \\ xy =  \frac{4}{5} ..(2) \\ this \: i s \: the \: equation \: of \: variation \\ plug \: x = 1 \: in \: (2) \\ 1 \times y =  \frac{4}{5}  \\  \huge \red{ \boxed{y =   \frac{4}{5}  }}
