Answer:
She incorrectly multiplied 15 X 1/4
Step-by-step explanation:
Answer:
$6.03
Step-by-step explanation:
Let's begin by listing out the given variables:
height (h) = 12 cm, diameter (d) = 8 cm, r = d ÷ 2 ⇒ r = 4 cm, cost of coconut oil (c) = $0.01 /cm³
The formula of cylinder is given by:
V = πr²h = π * 4² * 12 = <u>603.1858 cm³</u>
cost of filling the tin can with coconut oil = cost of coconut oil * Volume of cylinder
Cost = c * V = 0.01 * 603.1858
Cost = $<u>6.03</u>
Answer:
9 degrees
Step-by-step explanation:
given:
Initial temperature : 17 degrees
temperature change = reduction by 8 degrees (i.e - 8 degrees)
hence the final temperature
= initial temperature + temperature change
= 17 + (-8)
= 17 - 8
= 9 degrees
Step-by-step explanation:
7x + 10 = 4x + 16
3x + 10 = 16 (subtract 4x on both sides)
3x = 6 (subtract 10 on both sides)
x = 2 (divide 3 on both sides)
