Alecsey [184]3 years ago

Apparently you had to scooty out of here before you had a chance to
tell us what the choices are.  So there's no way for anybody to help you
find the correct ones.

For an equation to show direct variation:

-- When either 'x' or 'y' is zero, the other one must be zero too.

-- 'x' and 'y' must both be to the first power in the equation. 
     What I mean is;  no squares or higher powers of 'x' or 'y',
     no square roots, or cubes etc.

and

-- If 'x' or 'y' is in the denominator of a fraction,
then it has to be in the numerator too.

nikitadnepr [17]
1mi = 5280feet
 The first thing you should do in this case is to calculate the perimeter of the rectangle which will be given by:
 P = 2 * L + 2 * W
 Where
 L = long
 W = width
 Calculating we have:
 P = 2 * (1/4) + 2 * (1/8)
 P = 1/2 + 1/4
 P = 3/4 mi
 To calculate this distance to feet we have to use the following expression:
 (3/4) / (x) = 1/5280
 answer:
<span> B) 3/4 miles divided by x= 1 mile/5280ft

A teacher is cutting pieces of tape for the marshmallow challenge.The roll of tape is 16.8 meters long and each piece measures 1
Zanzabum

Given:

Total length of tape in roll = 16.8 meters

Length of each piece = 1.125 meters

Number of pieces = 8

To find:

The remaining tape.

Solution:

We have,

Length of 1 piece = 1.125 meters

Length of 8 piece = 8 × 1.125 meters

                              = 9 meters

Total length of tape in roll = 16.8 meters

Remaining tape = Total length of tape in roll - Length of 8 piece

                           = 16.8 - 9 meters

                           = 7.8 meters

Therefore, the length of remaining tape is 7.8 meters.
