Susan found a bag of 20 golf balls at a garage sale, and bought the bag for 75 cents. express the ratio of cost to number of balls in lowest terms. 20: 75 75: 20 4: 15 15: 4

It would be 4:15

Step-by-step explanation:

You would take 20 and 75 and put them in a ratio that would look like this 20:75, then they are divisable by 5 so you reduce them, when you reduce them you get 4:15

4.5%

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
