djyliett [7]

Answer:

5/2cups

Step-by-step explanation:

If a recipe serves 6 and calls for 3/4cups, arecipe that serves 20, will call for (20×3/4)/6 cups. Mathematically;

6recipe = 3/4cups

20recipe = x

Cross multiplying we have;

6x = 20×3/4

6x = 15

x = 15/6

x = 5/2

This means a recipe that serves 20 will call for 5/2cups

The park and movie theater are 3.4 inches apart on a map. If the map has a scale of 0.25 inch = 5 miles, find the actual distanc
lianna [129]

The actual distance between park and movie theater is 68 miles, if the park and movie theater are 3.4 inches apart on a map and the map has a scale of 0.25 inch = 5 miles.

Step-by-step explanation:

The given is,

             Park and movie theater are 3.4 inches apart

             Map has a scale of 0.25 inch = 5 miles

Step:1

            Formula to calculate the number of scales for distance between park and theater,

                                        = \frac{Distance in map}{Scale value of map}

                                        = \frac{3.4}{0.25}

                                        = 13.6

            number of scales for distance between park and theater  = 13.6

Step:2

            Formula to convert distance inches to miles

                                      = Number of scale × Equivalent value inches to miles

                                      = 13.6 × 5

                                      = 68

            Actual distance between park and theater = 68 miles

Result:

           The actual distance between park and movie theater is 68 miles, if the park and movie theater are 3.4 inches apart on a map and the map has a scale of 0.25 inch = 5 miles.

Answer:

130.356 g

Step-by-step explanation:

The problem tells you there is a proportional relationship, so set up a proportion and solve..

99.684 is to 11.7 as X is to 15.3

Written as a math equation like this...

99.684/11.7 = X/15.3

Now solve for X

130.356 = X    (multiply both sides by 15, then simplify)
