Answer: A cardboard box without a lid is to have a volume of 32,000 cubic cm. Find the dimensions that minimize the amount of cardboard used
. ans: base 40 x 40, height = 20
Solution:
The typical box might look like the one below
where . In addition we have xyz = 32000 ,so we need to minimize .
We have,
From the geometry of the problem so y = x. So or x = 40.
Finally, y = x = 40 and z = 32000/(xy)=20.
Answer:
17
Step-by-step explanation:
There is a SUBTRACTION symbol in the problem. So, you will do the opposite, & ADD the 2 available numbers in the equation. 10+7=17
When you replace that y with 17, the equation is correct.
Answer:
$2611.05
Step-by-step explanation:
earnings = lane rentals + concessions
<u>Friday</u>:
earnings = $842.72 +412.38 = $1255.10
<u>Saturday</u>:
We assume "down by 1/8" means the value was 1 -1/8 = 7/8 that of the previous day. Likewise, "increased by 1/2" is assumed to mean the value was 1 + 1/2 = 3/2 that of the previous day.
earnings = 7/8×$842.72 + 3/2×412.38 = $1355.95
__
Then the total earnings for both days were ...
$1255.10 +$1355.95 = $2611.05
