Answer:
100 x 4 = 400 - 91 = 309
Step-by-step explanation:
The roller coaster will need to run 4 times.
Explanation:
If there are 15 adults and 9 children, then we know that they're 24 people in total on the line (15 + 9 = 24). Now, we divide 24 by 6, because there are 24 people and a roller coaster holds up to 6 people. 24/6 = 4, therefore the roller coaster will need to run 4 times.
Answer:
see below :)
Step-by-step explanation:
This is a little complicated but base e which means Euler's number is usually used when solving logarithms. base e equals to 2.71828. You can kind of compare this to pi. This is an irrational number and usually is used in natural logs. I hope this helps.
<span>The perimeter of the area is the length of the fence.
Perimeter = x + y + y. This can be simplified to
Perimeter = x + 2y. You're told that the rancher has 100 m of fence, so the perimeter is 100 m:
100 = x + 2y (1)
The area of a rectangle is given by the formula A = length * width. The length in this case is x, and the width is y.
So, A = xy.
Solve equation (1) for y. Once you find the expression to which y equals, plug that for y into A = xy.
100 = x + 2y. Solve for y by subtracting both sides by x:
100 - x = 2y. Divide both sides by 2:
(100 - x)/2 = y
Substitute (100 - x)/2 for y into A = xy:
A = x[(100 - x)/2]
A = [x(100 - x)]/2
You can rewrite this as (100x - x²)/2 or 50x - (x²/2) or 50x - (1/2x²).
Hope that helped!</span>
