Bobby bought 1.12 pounds of turkey at a cost of 2.50 per pound. carla bought 1.4 pounds of turkey at a cost of 2.20 per pound. who spent more and by much?

CARLA

Step-by-step explanation:

STEP 1: BOBBY: FIRST YOU MULTIPLY 1.12 BY $2.50, AND YOU GET $2.80. $2.80 IS HOW MUCH BOBBY SPENT.

STEP 2: CARLA: YOU HAVE TO DO 1.4 TIMES $2.20, AND YOU'LL GET $3.08.

THEREFORE, CARLA SPENT MORE MONEY

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
