The concept used here is the place values. Each digit of a number holds it own value that is determined by its relative location within the number. Starting on the rightmost digit, the value increases by 10. The ones digit has a value of 1. The tens digit has a value of 10. The hundreds value has a value of 100.
The rightmost 4 has a value of 1, so its exact value is 4*1 = 4. The middle 4 is the tens place, so its exact value is 4*10 = 40. The third 4 from the right is in the hundreds place, so its exact value is 4*100 = 400.
Answer: the distance from one corner of the field to the other corner is 136 m
Step-by-step explanation:
The distance from one corner to the other corner is the diagonal and it
divides the field into two equal right angle triangles. The diagonal represents the hypotenuse of each right angle triangle. The length and width of the rectangle represents the adjacent and opposite sides of the right angle triangle. To determine the length of the diagonal, d, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Therefore
d² = 110² + 80²
d² = 12100 + 6400 = 18500
d = √18500
d = 136 meters

Answer:
25 hrs
Step-by-step explanation:
#First, we calculate the average earnings per hour by subtracting the running costs from receipts:
Let x be the number of hours it takes to fully recover the investment costs. We divide the investment cost by net receipts to solve for x;
Hence, it takes 25 hrs to repay the investment cost.
