Glen is looking into buying a piece of land. He estimates that the land measures 100 yd by 850 yd. The land is actually 140 yd by 940 yd. What is the percent error in the estimated area of the land? A. 35.4%
B. 17.7%
C. 64.6%
D. 32.3%

Answers

1) First find the areas:
100 * 850 = 85000
140 * 940 = 131600
2) Find the percent error in the area
percent error = (experimental value - accepted value)/(accepted value) *100
% error = (85000 - 131600)/(131600) * 100 = 35.4%

the ratio 1mm represents 1cm is the same as 1:10 complete the following the ratio 1cm represents 1km is the same ratio as 1:

Answers

Answer: 1:100

Explanation: If 1cm is 10 and there is 1mm for every 10cm, and the unit that is after centi- is kilo- then all you’d have to do is put another zero.

Final answer:

Given that 1 km is equal to 100000 cm, the ratio of "1 cm represents 1 km" is identical to the ratio of "1:100000."

Explanation:

The ratio in the question has been adjusted from millimeters to centimeters and is presently being altered from centimeters to kilometers. In light of the fact that 1 centimeter is equal to 0.00001 kilometers, the original ratio of 1cm:1km can be restated as 1:100000. In other words, 1cm represents 1km is the same ratio as 1:100000. This is a demonstration of how units of measure can impact ratios and proportions in mathematics.
