What do u want to do to it??
Answer:
(a) 55080 m³
(b) 1312 truckloads
(c) 11 days
Step-by-step explanation:
(a) We have a rectangular prism with the dimensions 12 by 85 by 54, so the volume is just the product of these numbers:
V = 12 * 85 * 54 = 55080 m³
(b) The truck can hold 42 m³ of earth, so divide 55080 by 42 to get the number of truckloads required:
55080 / 42 = 1311.4
Since we will still need a truckload to hold that little bit of earth that involves 0.4 of a truck, we round up to 1312 truckloads.
(c) In one day, 4 trucks work for 6 hours and since each truck can remove 42 m³ with 5 loads per hour, we have:
42 * 5 * 6 * 4 = 5040 m³ earth removed a day
Divide 55080 by 5040 to get the number of days:
55080 / 5040 = 10.9 ≈ 11 days
Answer:
i need to see the graph
Step-by-step explanation:
[(29+18) + (17-8)] / 8
Remember we start with the grouping symbols first, starting with the parentheses.
29+18 = 47
17-8 = 9
Then we add them together.
47+9 = 56
So now we have:
[56] / 8
56 / 8 = 7
The answer is 7
7y+9=7y-6
9 is not equal to -6
