Pleas please help! Solve for d. 3/15 - d/5 = 5/6 + d/3

ololo11 [35]

$\frac{3}{15}$ - $\frac{d}{5}$ -( $\frac{5}{6}$ + $\frac{d}{3}$ =0

Step 1: $\frac{5}{6}$ + $\frac{d}{3}$ = $\frac{3}{15}- \frac{d}{5}- \frac{(2d+5)}{6}=0$

Step 2: $\frac{1}{5}- \frac{d}{5}= \frac{(1-d)}{5}- \frac{(2d+5)}{6}=0$

Step 3: $\frac{(1-d)*6-(2d+5)*5}{30}= \frac{-1*(16d+19)}{30}$

Step 4: $16d= -19:Divide \ both \ sides \ by \ 16:d= \frac{-19}{16}= -1.188$

Your answer is $d\boxed{\boxed={ \frac{-19}{16}= -1.1888}}}}$

An alligator population in a naturer preserve in the Everglades increased by 60 alligators or five years what is the mean yearly

adelina 88 [10]

I'm not sure what you meant after alligators, if it was or or for, but I think it was for so I'm going with that. If 60 increase every 5 years, it would be 60 over 5 (in fractions). So I would do 60 divided by 5, which would be 12. So that means 12 increase every year. I'm not sure what mean meant either, if you're talking about the mathematical mean, but you can't solve the mean in this problem. The Answer: The yearly change in the alligator population would be 12.

Find the arc length of the 3/4 of a circle with a radius of 5

IgorLugansk [536]

Answer:

7.5 pi

Step-by-step explanation:

The formula for arc length of a sector is denoted as

$\frac{x}{360}2\pi r$ , where x is the central angle of the sector.

Since the sector is 3/4 of a circle, the central angle will be 3/4 of 360 degrees.

3/4 of 360 is 270, so we have our central angle. We also have our radius which we can plug into the formula.

$\frac{270}{360}2(5)\pi$

2 times 5 is equal to 10, and 270/360 simplifies to 3/4. 3/4 times 10 is equal to 7.5, so the answer is 7.5 pi
