Find the following percents. Round to the nearest thousandth when necessary. 6% of 300.
finlep [7]

300/x=100/6

(300/x)*x=(100/6)*x    

300=16.6666666667*x      

300/16.6666666667=x  

x=18

Therefore the answer is "18."

Elaina Kicks A Soccer Ball With An Initial Velocity Of
VladimirAG [237]

By using the motion equations, we conclude that she will make the goal.

<h3>Will she make the goal?</h3>

First, we know that the goal is 20ft away, and the position in x is given by:

x = 28*cos(58)*t

Let's find the time in which the ball will travel these 20 ft.

20 =  28*cos(58)*t

(20)/(28*cos(58)) = t = 1.35

So the horizontal distance is covered in 1.35 seconds, now let's see which is the height of the ball at that time.

The height equation is:

y = -16*t^2 +28*sin(58)*t

Evaluating in t = 1.35 we get:

y = -16*(1.35)^2 +28*sin(58)*1.35\\\\y = 2.9

And the goal is 5ft tall, so we can conclude that she will make the goal.

What is the solution to the equation 3 x+ 2 = -x-57<br> X=-8<br> o x=-7<br> o x=7<br> O X=8
luda_lava [24]

Answer:

x = -59/4

Step-by-step explanation:

3 x+ 2 = -x-57

Add x to each side

3 x+x+ 2 = -x+x-57

4x+2 = -57

Subtract 2 from each side

4x +2-2 = -57-2

4x = -59

Divide each side by 4

4x/4 = -59/4

x = -59/4
