Answer:
7 inches by 19 inches
Step-by-step explanation:
We can use a system of equations for this.
<em>x=length</em>
<em>y=width</em>
2x+2y=52 (Perimeter)
xy=133 (Area)
We must find x and y that fit both these equations.
Hope this helps :)
Answer:
C. And the reference angle is pi/3
Step-by-step explanation:
Let me give you a little quick way to do this. You’re probably trying to memorize the unit circle and figure out what 2pi/3 equals. However, all you need is a bit of math.
Start with the denominator and multiply the numerator by its correct angle
Anything with 3 in it’s denominator, is a multiple of a 60 degree angle. The numerator is 2 so do 60 x 2, which equals 120. Your angle is 120 and will land in the top left quadrant.
Moving on to the reference angle. Think of this as being what you have left on the horizontal axis. The angle took up 120 degrees. Now find the rest. 180 - 120 = 60. Pi/3 equals 60 degrees
Answer:
Step-by-step explanation:
volume of soil = 12×8×(12-2) = 960 in³
Answer:
250 boys attended the conference.
Step-by-step explanation:
First, divide 750 by 3 (one-third of the conference is boys) and you will get 250 (number of boys). If you wanted to find the number of girls too, you would simply double 250 to get 500 girls.
It should be 20 if I’m right
