A recipe for pie crust calls for two cups of butter to be added for each three cups of flour. If Jono needs to make many crusts and has a total of 10 cups of flour, which of the following is closest to the number of cups
of butter he will need?
(1) 5 cups
(3) 7 cups
(2) 6 cups
(4) 8 cups

7 cups of butter

Step-by-step explanation:

2 cups of butter for each three cups of flour

Let the number of butter cups for 10 cups of flour = x

2 cups of butter = 3 cups of flour flour

x = 10 cups of flour

Cross multiply :

3x = 10 * 2

3x = 20

x = 20 / 3

x = 6.666

x = 7 cups of butter (nearest whole number)

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
