Answer:
circle a circumference is 25.13 and the area is 50.27. circle b circumference is 9.42 and the area is 7.0 7
I have no clue about part C
Answer:

because its 50$ for setup and 30 each hour for 5 hours. so 30x5=150 +50 = 200÷ nelson and 3 friends =50$ each
Answer:
0
Step-by-step explanation:
Any value to the 0th power will be equal to one so 1-1 is equal to zero. Any number multiplied by 0 is equal to 0.
Draw a right triangle ABC so that m∠C = 90°
The lengths are:
Side a is opposite ∠A,
Side b is opposite ∠B,
Side c (the hypotenuse) is opposite ∠C
Because cos A = x, therefore
x = b/c => b = cx (1)
Because sin A = y, therefore
y = a/c => a = cy (2)
By definition,
tan A = a/b
= (cy)/(cx)
= y/x
Answer: b. y/x
