A box of cereal states that there are 72 calories in a 3/4-cup serving. What is the unit rate for calories per cup? How many calories are there in 3 cups of cereal?

400 calories in 4 cups of cereal.

Step-by-step explanation:

The unit rate is how many calories are in 1 cup of cereal.

Set up a proportion:

Cross multiply and solve:

There are 100 calories per cup of cereal.

To get the calories in 4 cups of cereal, simply multiply the unit rate of 100cals/cup by 4.

There are 400 calories in 4 cups of cereal.

3 qrs + 3/2 xy hope this : /

step-by-step explanation:

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
