Since the measurement of the longest side is missing we can use the pythagorean theorem to find the hypotenuse or longest side.

18^2 + 32^2 = c (hypotenuse) ^2
324 + 1,024 = c^2
1,348 = c^2
sqrt 1,348 = c
36.72 = c
i do not agree with ted because when you use the pythagorean theorem you do not get 47cm

this can be proved by
18^2 + 32 ^2 = 47^2
we already know the left side is 1,348
1,348 = 47^2
1,348 does not equal 2,209 which is 47 squared

Select the correct answer.
Yuliya22 [10]

Answer: B is your correct answer.

Step-by-step explanation: If she has already made $95.00 from selling jam and made $24.00 from demonstrations you add those together to get $119. Then you subtract $119.00 from $450.00 and you'll have $331.00 left to make. Finally you divide $331.00 by $5.00 (cost of jam) and you'll find that you have to sell 66 more jars of jam.
