Answer for number 4 is hour.
Step-by-step explanation:
Maximum hour spent for all homework (English homework + math homework) is 2 hours.
Let us assume the hours spent for English homework be 'e'.
It is given that:
(Hours spent for math homework) = 2 × (Hours spent for English homework)
Hours spent for math homework = 2 × e = 2e
Total hours spent = (Hours spent for math homework) + (Hours spent for English homework)
Total hours spent = 2e + e = 3e
2 = 3e
3e = 2
∴ e =
Therefore number of hours spent on English homework is equal to hours.
Answer:
The answer would be 230.85
The area of a triangle is (1/2) * (base) * (height) .
It varies jointly with the length of the base and the height.
The constant of variation is the (1/2) .
Only two 45's can go into 130
Answer:
Step-by-step explanation:
I'm thinking you want to know the height of the ball on that 5th bounce, right? This is of the form
where a is the initial height and b is the decay factor. If the ball comes up to 2/3 of its height from the previous bounce, then b = 2/3 and our equation is
If you want to know the height y of the 5th bounce x, sub in a 5 for x and solve for y:
and get that
y = 320/81 or as a decimal, 3.9506 feet
