The area of any regular polygon can be expressed as:
a(n,s)=(ns^2)/(4tan(180/n)), where n=number of sides and s=side length
(notice apothem is not needed :P)
a(6,5)=(6*5^2)/(4tan(180/6)
a(6,5)=37.5/tan30
a(6,5)≈64.95 units (to nearest hundredth of a unit)

Answer: 55% of the students passed the math test
Step-by-step explanation: The fraction
represents the number of students who passed the math test out of all the students that took the test.
To find out what percent of the students that took the math test passed, we can turn the fraction
into a percent.
To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. So to write
as a percent, we need to find a fraction that is equivalent to
with a 100 in the denominator. We can do this by setting up a proportion.

Now, we can use cross products to find the missing value.
4,400 = 80n
÷80 ÷80
55 = n
Therefore, 55% of the students that took the math test passed it. This should make sense because 40/80 would be half and 44 students is only a little over 50%.
Answer: 105k
Step-by-step explanation:
1. Multiply the number by three (35kg x 3)
2. Use your answer (105kg) and convert it to grams
3. GET YOUR ANSWER = 105k Grams
4. Therefore, Rosie weighs 105k grams
