Answer:
A. a little more than 1/4 of the students prefer video games
B. I think the most reasonable prediction is 25
Answer:
no
If he used 50% on ticket for rides, the remaining tickets he would have is (100% - 50%) 50%.
He used 1/10 on video games. Converting 1/10 to percentage gives 10%.
The total percentage of tickets used is 60%. He should have 40% to spend on batting cages
Step-by-step explanation:
Octagon, stop sign.
Eight isoscles triangles. It looks like we're told the side is 9.9 and the height to the side (also called the apothem) is 12.
So each isosceles triangle has area (1/2)(9.9)(12) and we have eight of them,
area = 8(1/2)(9.9)(12) = 475.2
Answer: 475.2
Usually we wouldn't be told 9.9 -- this is the baby version. We know each of those isoscles triangles has unique angle 360/8=45 degrees, so the apothem and half the side of the octagon are a right triangle with acute angle 22.5 degrees.
The area of the right triangle with long leg 12, short leg x,
tan 22.5 = x/12 or
x = 12 tan 22.5
Twice that is what we're told is 9.9; let's check:
2x = 24 tan 22.5 = 9.941125496954282
The area of the little right triangle is
(1/2) 12 × 12 tan 22.5
and there are 16 of these
16 (1/2) 12 × 12 tan 22.5 ≈ 477.174
Answer:
5
Step-by-step explanation:
10 - 5 = 5 the range is the difference from the highest value to the lowest value
