There are 650 toothpicks in a regular sized box.
That is the volume of the box = 650 toothpicks
Jumbo box is made by doubling all the dimensions.
We know volume = length * width * height = L*W*H
We double all the dimensions for Jumbo box
L becomes 2L
W become 2W
H becomes 2H
Volume of Jumbo box = 2L * 2W * 2H = 8*L*W*H
Volume of jumbo box = 8 * volume of small box
= 8 * 650= 5200
The Jumbo box holds 5200 toothpicks .
11:30-10:00=1 hr and 30 min
5:00-2:00=3 hrs
Answer
h^-1(x)= x+43
Explanation
h(x)=x-43
Use substitution
y=x-43
Interchange the variables
x=y-43
Swap the sides
y-43=x
Move the constant to the right
y=x+43
Use substitution
h^-1(x)=x+43
