Step-by-step explanation:
Answer:
236 cm^2
Step-by-step explanation:
Formula
Area = sector angle/360 * pi * r^2
Givens
Sector angle = 120
r = 15
Solution
Area = 120/360 * 3.14 * 15 * 15
Area = 1/3 * 3.14 * 225
Area = 235.5
Area = 236 cm^2
Answer:
This was translated 180 degrees clockwise around the origin.
Step-by-step explanation:
In order to find this, simply look for where the point is from it's original point. You'll notice that each point changes into the quadrant diagonal from it's original quadrant. Since this happens with each one, we know it must rotate roughly 180. Also, since each line is parallel to it's original spot, it is exactly 180 degrees around the origin.
Using equation, He bought 3 boxes of ballpoint pens and 15 boxes of felt-tip pens
<h3>How to find the boxes of each type of pen using equation?</h3>
let
x = number of boxes of ballpoint pens
y = number of boxes of felt-tip pens
Therefore, the situation will form an equation.
x = 5y
Hence,
4.33x + 3.42y = 75.21,
4.33(5y) + 3.42y = 75.21
21.65y + 3.42y = 75.21
25.07y = 75.21
y = 75.21 / 25.07
y = 3
x = 5(3) = 15
Hence, he bought 3 boxes of ballpoint pens and 15 boxes of felt-tip pens
