What is the answer, Shelby made 5 quarts of juice for a picnic. How many cups of juice did shelby make?
Anvisha [2.4K]

Given, Shelby made 5 quarts of juice for a picnic.

We know that 1 quart of juice = 4 cups of juice.

Here we will have to convert 5 quarts to cups.

As for 1 quart there are 4 cups, to find 5 quarts we have to multiply 4 times 5.

So 5 quarts of juice = (4)(5) cups of juice.

We know that, (4)(5) = 20

5 quarts of juice = 20 cups of juice.

We have got the required answer here.

Shelby made 20 cups of juice there in the picnic.

NeTakaya

Answer: The answer would be No, Yes, No.

Step-by-step explanation:

Look at the grid, you can see that it has 100 units in all.

0.42 equals 21/50, so they are both wrong. The denominator would have to be 100. The only logical one would be the second one.

HD Straight line graphs
Taya2010 [7]

Answer:

The equation of the sraight line  3x- y+ 6 =0

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the gradient of the function

   |gradf| = 3  and point (-1,3)

Given that the slope of the line

 m = 3

The equation of the straight line passing through the point(-1,3) and slope m =3

y -y_{1} = m(x-x_{1} )

y-3 = 3(x-(-1))

y-3 = 3x+3

3x +3-y+3=0

3x- y+ 6 =0

<u><em>Final answer:-</em></u>

The equation of the sraight line  3x- y+ 6 =0

<u><em></em></u>
