50 / 100 = .5
.5 is 1% of 50
.5 * 20 = 10
Does that help?
Answer: 12
Step-by-step explanation:
6-2 + 4 x 2 = 6 - 2. + 8
4 + 8 = 12
Since the circle is inside the square, the diameter of the circle is the same length as a side of the square.
The length of the side of the square is found by taking the square root of the area:
Side length = SQRT(144) = 12 m
The circumference of a circle is found by multiplying the diameter by PI:
12 x 3.14 = 37.68 = 37.7 m
Answer:
Object point Q (x,y) ------------- image point Q'( -y,x)
Step-by-step explanation:
When a point A (x,y) is rotated 90 degrees counterclockwise about the origin the resulting image of the point is A'(-y,x)
This means first you alternate the positions of x and y coordinates then add a negative sign on the now new y coordinate.
Example a point B(2,3) rotated 90° counterclockwise about the origin will form an image B'(-3,2)
So if point Q (x,y) ------------- image Q'( -y,x)
Substitute real values for (x,y) coordinates to get correct answer.
