Answer:
I think its 7.5 but I might be wrong
Step-by-step explanation:
Out of 1,200 students, 700 are boys. Therefore, the fraction would be

.
To convert this into a percentage, divide 700 by 1,200.

= 0.583333 (or just 0.583 if you round)
Multiply 0.583
by 100 to get a percentage.
0.583 · 100 =
58.3So, the percent of boys at the school is

Answer:
B
Step-by-step explanation:
Apply the Pythagorean Theorem to determine whether or not the given triplets represent right triangles or not:
I. 5 feet and 13 feet: 5^2 + 12^2 = 13^2 is TRUE
II. 9 ft and √63 ft: 9^2, 63, 12^2: 63 + 81 do add up to 144 TRUE
III. 2, 10, 12^2: 2 + 10 do NOT add up to 144. FALSE
Answer B is correct
Answer:
28, 29, and 30
Step-by-step explanation:
There's probably better ways but you can estimate by knowing 30*3=90 so it should be somewhere pretty close to 30. Guess and check with basic calculations to get 28, 29, and 30.
