Answer:
16 units
Step-by-step explanation:
We know a square is 4 sides, and perimeter is the sum of all sides.
4 + 4 + 4 + 4 = 16 units
we can do this in a more efficient way with:
4 x 4 =16 units
180=51+2x+3+4x+8
180=51+11+6x
180=62+6x
-62 -62
-----------
118=6x
---------
6x 6x
x=17
exterior angle = 4x+8
4(17) + 8
68 + 8
76
Using the formula for circumference from diameter (c=pi(d)), we find that the circumference of the ferris wheel is about 197.97 feet. We then multiply that number by the revolutions to get 2,374.64 feet, which is the answer.
To get an average score of 80% (out of four exams), a total of 4*80%=320% is needed, so the minimum required for the 4th test is 320-(75+97+60)=88.
To get an average score of 89% (out of four exams), a total of 4*89%=356% is needed, so the maximum required for the 4th test is 356-(75+97+60)=124, which is impossible.
So the next exam grade must range between 88 and 100 to get a grade b in the class.
Hoped I help! Mark brainly it would help<3
Its wrong for x = 2
y = (3/4) * 2^2 = 3 (NOT 4)
