Answer:
225 milliliters
Step-by-step explanation:
Marianne tried to drink a slushy as fast as she could. She drank the slushy at a rate of 4.5 milliliters per second. After 17 seconds 148 5 milliliters of slushy remains. how much slushy was originally in the cup?
let x = slushy originally in the cup
total slushy consumed in 17 seconds = 17 x 4.5 = 76.5 ml
x - 76.5 = 148.5
collect like terms
x = 148.5 + 76.5
x = 225 ml

Answer:
9 feet
Step-by-step explanation:
The sine relation applies.
Sin = Opposite/Hypotenuse
sin(30°) = height/(18 ft)
height = (18 ft)sin(30°) = (18 ft)(1/2)
height = 9 ft
The ladder extends 9 feet up the side of the building.
