Complete Question
Marisa painted one-half of her bedroom in three-fourths of an hour. At this rate, how long would it take her to paint the entire room? three-eighths of an hour eight-thirds of an hour four-sixths of an hour six-fourths of an hour
Answer:
six-fourths of an hour
Step-by-step explanation:
Let her entire room be equal to 1
From the above question
1/2 of her bedroom = 3/4 of an hour
1(Entire bedroom) = x hour
Cross Multiply
1/2 × x = 3/4 × 1
x = 3/4 / 1/2
x = 3/4 ÷ 1/2
x = 3/4 × 2/1
x = 6/4 hour
Hence, it would take Marissa six-fourths(6/4) of an hour to clean her entire room.
Answer:
88
Step-by-step explanation:
6 + 5 = 11
8 ÷ 2 = 4
11 · 4 = 44
44 · 2 = 88
Answer:
See explanation
Step-by-step explanation:
Given that the equation for the firecracker is h = − 5 t^2 + 30 t + 20
It is impossible to solve this question unless the height (h) in meters is supplied. If the height was supplied, we could set up the quadratic equation and solve it yielding two values for the time. The values of t obtained is the time in seconds required for the firecracker to reach the given height h.
You can apply these tips and solve the question seamlessly.

Answer:
x = (y+6)÷5
Step-by-step explanation:
y=5x-6 (adding 6 both sides)
y+6=5x (dividing by 5 both sides)
x = (y+6)÷5 Answer
