Answer:
$1.89 per used book
Step-by-step explanation:
Divide the total price ($9.45) by the amount of items (5) and you get the unit price of $1.89 per item
Answer:
168 units cubed
Step-by-step explanation:
so we know it's base times height right
so like identifying the base doesn't matter as long as you're smart enough to figure how to calculate then whatever lol
so like the base let's just say it's the triangle because that's probably what you're struggling on
so the base of the triangle is like what lol 6 * 8 / 2 = 48 / 2 = 24 so then you have the base multiply by the third dimension
24 * 7 = 140 + 28 = 168 so yeaaaaaaa and it's cubed because it's three dimensional
You didn't type the equation correctly.
Answer:
Minimum unit cost = 5,858
Step-by-step explanation:
Given the function : C(x)=x^2−520x+73458
To find the minimum unit cost :
Take the derivative of C(x) with respect to x
dC/dx = 2x - 520
Set = 0
2x - 520
2x = 520
x = 260
To minimize unit cost, 260 engines must be produced
Hence, minimum unit cost will be :
C(x)=x^2−520x+73458
Put x = 260
C(260) = 260^2−520(260) + 73458
= 5,858
3:45
1/3 of an hour is 20 minutes.
8:05 + 20min = 8:25
8:25 + 7 hrs = 3:25
3:25 + 20 min= 3:45
