Answer:
Step-by-step explanation:
1.Turn the 9 into a fraction
2.factor the bigger numbers.
3.Cancel out the common factor(3)
4.multiply across
So what we want to know is how long is the car that is 6% shorter then the other car. We can look at it this way: the shorter car is 94% the lenght of the longer car. Lets call the length of the shorter car x, then we have the equation: 94% * 3.9m=x. Or, (94/100)*3.9=x. Now we solve for x and get: x= 3.666m. So the shorter car is 3.666 m long.
A right triangle is a triangle that consist of an angle which one angle is 90degree and the remaining angle would be less than to 90 and the best answer to your question based on my calculation i think the answer is A.
C = circumference of circle
p = perimeter of square
c + p = 29
p = 29 - c
side of square = (29 - c)/4
radius of circle = c/(2pi)
a = side^2 + (pi)r^2
a = ((29 - c)/4)^2 + pi * (c/(2pi))^2
a = (1/16)(841 - 58c + c^2) + (c^2/(4pi^2)) * pi
a = 52.5625 - 3.625c + c^2/16 + c^2/(4pi)
Since the 2nd degree term has a positive coefficient is positive, this has a graph that is a parabola opening up. It has a minimum value.
We take the derivative of the area expression and set equal to zero to find the minimum circumference.
da/dc = -3.625 + c/8 + (c/(2pi)) = 0
c = 12.76
Answer: 12.76 cm
