The volume of a rectangular box is 1600 cubic inches. The height of the box is 8 inches and the length of the box is 2 times lon
Anastasy [175]

Answer:

0.833 feets

Step-by-step explanation:

Given that:

Volume of box = 1600

Heigh of box (H) = 8 inches

Let:

Width of box (W) = x

Length of box (L) = 2x

Volume of box = (Height * width * length)

1600 = (8 * x * 2x)

1600 = 16x²

x² = 1600/16

x² = 100

x = sqrt(100)

x = 10 inches

Hence, width of box in feet:

1 inch = 0.0833 feets

10 inches = (10 * 0.0833) feets

= 0.833 feets

Donald sells 760 marbles everyday. He sells each marble for 1.5 dollars. For how many days does Donald need to sell marbles to e
Harman [31]

Answer:

Donald needs 3 days to earn 3420 dollars

Step-by-step explanation:

Donald sells 760 marbles everyday. He sells each marble for 1.5 dollars

amount collected in one day= 760 \cdot 1.5=1140 dollars

In one day the amount earned is 1140 dollars

we need to find the number of days needs to earn 3420 dollars

Number of days needed is \frac{3420}{1140}=2.842

So its around 3 days

Donald needs 3 days to earn 3420 dollars

How mlong would it take to dig a hole 10 m by 10 m by 10 m?
deff fn [24]
That depends on how quickly the hole is being dug. First, you have to find how many cubic feet this hole is. That's fairly simple; length times height times depth equals volume, so the hole is 1,000 cubic feet. Say you're digging at one cubic foot per ten minutes, then it would take you 10,000 minutes (166 hours, about seven days) so just under a week to dig a hole at that rate.
