Ron Finley is a gardener who decided a few years ago to plant several gardens in South Central Los Angeles. He wants his next ga
yaroslaw [1]

Well, we can be sure that whatever the width is, we can call it ' W '. Then, from information in the question, the length of the garden is ' 3W '.

Now, the perimeter of a rectangle is (length + width + length + width). Using the fancy algebra labels I just gave them, that's (3W + W + 3W + W). And now I can go through that, add up all the Ws, and get a total of 8W for the perimeter.

But he question tells us that the perimeter is 24 yards, so 8W = 24 yds.

Divide each side of that equation by 8, and we discover that W = 3 yds. And if THAT's true, then 3W = 9 yds. Bada bing ! We have the dimensions of the garden.

It's 3 yards wide and 9 yards long.

SVEN [57.7K]

Answer:Marvin burned more calories per hour.

Step-by-step explanation:

Thomas went for a long hike and burned 657 calories in 2 1/2 hours. Converting 2 1/2 hours to improper fraction, it becomes 5/2 hours

This means that the amount of calories that Thomas burnt in 1 hour would be 657 × 2/5 = 262.8 calories per hour

Marvin decided to go for a bike ride and burned 1,035 calories in 3 1/4 hours. Converting 3 1/4 hours to improper fraction, it becomes 13/4 hours

This means that the amount of calories that Thomas burnt in 1 hour would be 1035 × 13/4 = 3363.75 calories per hour

Therefore, Marvin burns more calories per hour.

\tan x+\frac{\cos x}{1+\sin x}\\\\ =\frac{\sin x}{\cos x}+\frac{\cos x}{1+\sin x}\\\\=\frac{\sin x(1+\sin x)+\cos^{2} x}{\cos x(1+\sin x)}\\\\=\frac{\sin^{2} x+\cos^{2} x+\sin x}{\cos x(1+\sin x)}\\\\=\frac{1+\sin x}{\cos x(1+\sin x)}\\\\=\frac{1}{\cos x}\\\\=\sec x
