The party was 5 hours. 353.86-200.51=153.35 then you divide that number by 30.67 and you get 5.

Hey there! The answer will be below

B is the correct answer

Because in B the last 3 numbers are 500 (estimate) so 34,500 would be rounded to 35,000.Plus B makes the most sense.

Hope that helps!

A triangle has sides of 18cm and 32cm. The measurement of the longest side is missing. Ted says that one possibility for the unk
gulaghasi [49]
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
