Angie is testing her science fair project, an erupting model volcano. In her first trial, she uses 3 drops of red coloring and 5 drops of yellow coloring for the lava. In her second trial, she uses 4 drops of red coloring and 8 drops of yellow coloring. Which trial had a lower ratio of red coloring to yellow coloring? here are the answers:

The first trial had a lower ratio

The second trial had a lower ratio

Niether. Both trials have the same retio

step-by-step explanation:

sdfghjkl; vbnm,

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

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
