Hi there!

In order to solve this problem, we'll need to set up a proportion. The proportion we are going to use is x/120 = 50/100. Next, we'll cross-multiply, giving us 100x = 6000. Lastly, we'll divide each side by 100, giving us 60 5th graders that have a dog.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Hello!

First you have to convert the decimal into a percent

50% = 0.50

Multiply this by the amount of students.

120 * 0.50 = 60

The answer is 60

Hope this helps!

Use this equation to find dy/dx. 3y cos x = x2 + y2
Art [367]
Given: 3y cos x = x² + y²

Define y' =  \frac{dy}{dx}

Then by implicit differentiation, obtain
3y' cos(x) - 3y sin(x) = 2x + 2y y'
y' [3 cos(x) - 2y] = 2x + 3y sinx)

Answer:
\frac{dy}{dx} =  \frac{2x+3y \, sin(x)}{3cos(x)-2y}

x must equal 0 or - 10

and y must equal 1 or 6

or 3 x -10 = -30 plus 6 x 6 = 36 so -30 plus 36 is 6

*PLEASE HELP MEEEEEE* You throw a dart at the board shown. Your dart is equally likely to hit any point inside the square board.
yawa3891 [41]

Answer:

19.63%

Step-by-step explanation:

The probability of scoring 8 points is the probability of getting a dart into the green circle.

That probability is equivalent to the area of the circle divided by the total area of the square board.

The area of the circle according to A=\pi*r^2, is 25\pi cm squared

The area of the whole square board is one side squared: 20 squared = 400 cm squared

The probability is therefore equal to 25\pi/400 = \pi/16=0.19634=19.63%%
