Answer:
A. Eric rode 2 more miles per week than Kim rode
Step-by-step explanation:
Number of miles Kim rode bicycle in 9 weeks = 135 miles
Let x be the number of miles per week.
135miles => 9 weeks
x miles => 1 week


Kim rode the bicycle 15 miles per week
Number of miles Eric rode bicycle in 6 weeks = 102 miles
Let x be the number of miles per week Eric rides the bicycle.
102 miles => 6 weeks
x miles => 1 week


Kim rode the bicycle 17 miles per week
<em>Comparing the number of miles per week they rode, we would conclude that: "Eric rode 2 more miles per week than Kim rode".</em>
700 to the nearest hundred
Letter D
1-sin^2(x) = cos^2(x)
= sin^2(x)/cos^2(x)
= tan^2(x)
<u>Given</u>:
Given that the base of a pyramid is a rectangle with a width of 4.6 cm and a length of 9 cm.
The volume of the pyramid is 82.8 cubic cm.
We need to determine the height of the pyramid.
<u>Height of the pyramid:</u>
The height of the pyramid can be determined using the formula,

Substituting the values, we get;

Multiplying both sides by 3, we get;

Dividing both sides by 41.4, we have;

Thus, the height of the rectangular pyramid is 6 cm.
Hence, Option A is the correct answer.
