To find the percent of error divide how off the wrong answer was by the right number, then multiply by 100.
Bryan's guess of 730 was 120 less than the actual number so you would divide 120 by 850. 120/850 = 0.141
Then we would multiply that by 100. 0.141 * 100 = 14.1
His percent of error was 14.1%. The percent of error is negative since his guess was less than the right answer.

_____
A tangent intersects a circle at exactly one point.
Answer:
it will take Larissa 4 17/27 hours to finish 5lbs of goldfish
Step-by-step explanation:
1.5 pound = 1 1/2 pound equivalent to 3/2 pounds
3/5 of a 1.5-pound
= 3/5 × 3/2 pounds
= 9/10 lbs of goldfish eaten in 5/6 hours
how long, in hours, would it take her to finish a 5-lb box of goldfish?
Find the ratio
9/10 lbs of goldfish : 5/6 hours = 5lbs of goldfish : t hours
9/10 ÷ 5/6 = 5 / t
Solve for t
9/10 × 6/5 = 5 / t
54 / 50 = 5 / t
Cross multiply
54 × t = 50 × 5
54t = 250
Divide both sides by 54
t = 250 / 54
= 4 34/54
= 4 17/27 hours
Therefore, it will take Larissa 4 17/27 hours to finish 5lbs of goldfish
