Answer:
8
Step-by-step explanation:
hypotenuse = c = 17 feet
Height = a = 9 feet + 6 feet = 15 feet
Children's space = b
a^2 + b^2 = c^2
15^2 + b^2 = 17^2
225 + b^2 = 289 Subtract 225 from both sides
225-225+b^2=289-225
b^2 = 64 Take the square root of both sides.
sqrt(b^2) = sqrt(64)
b = 8
Since each child takes up 1 foot, 8 children can sit on side b.
Answer: D
Step-by-step explanation:
D is the only one that states the correct slope
There are 24 hours in a day, so 9 hours of the day is 9/24.
To reduce this, you need to recognize that both 9 and 24 are divisible by 3: 9=3x3 and 24=8x3
If you divide both by 3, you’d get your answer of 3/8.
You should sleep 3/8 of the day, when you’re 10 to 17 years old.
