C. multiply because of the order of operations
Answer:
1 hour and 42.8 minutes
Step-by-step explanation:
To answer this question let's call
while it takes Jenna to clean the gutters
Let's call
while it takes John to clean the gutters
h
h
t = total time
g = job = 1 (clean the gutters)
The speed of each one is:
g/ h
g/h

So:


h
Then, both together paint
of gutters for each hour.
This means that it takes
hours to clean the gutters together
Finally cleaning together takes 1,714 hours or also
1 hour and 42.8 minutes

Step-by-step explanation:
Answer:
6 511 104 in³
Step-by-step explanation:
Since we have 1 crate and 8 boxes fit into one crate.
So, volume of one crate, V' = 8 × volume of 1 box, V
Since the box is a rectangular prism of sides 2512 inches high, 18 inches long, and 18 inches wide, its volume, V = lwh where l = length of prism, h = height of prism and w = width of prism.
So, V = lwh = 18 in × 18 in × 2512 in = 813 888 in³
So, V' = 8 × 813 888 in³ = 6 511 104 in³
So, the minimum volume of the crate is 6 511 104 in³
