If 12 is 20%, then 24 is 40%, then 36 is 60%, then 48 is 80%, then 60 is 100%
So there are 60 questions on the test.
Answer:
28% of 82
Step-by-step explanation:
25% of 90 is 22.5
28% of 82 is 22.96
Let's say the point is (x,y) and it lies in 1st quadrant with both x and y as positive ,
Now let's say that the point is rotated by 270 degrees counter clockwise
It means The point will shift to the 4th quadrant , and we know that in 4th quadrant , the x is positive and y is negative ,
Also , as it is rotated by 270 degrees , the x and y values will interchange
SO there are two steps
1) Change the sign of x
2) Interchange the x and y values , i.e swap , x with y and y with x
Answer:
x = 11√2
Step-by-step explanation:
We can notice the triangle given is a special triangle, a 45°- 45°- 90° triangle. The hypotenuse of a 45°- 45°- 90° is √2 times the length of a side. We can set up the equation(using x as the side):
x * √2 = 22
We can divide by √2 on both sides to get:
x = 22 / √2
To rationalize the denominator, we multiply by √2 / √2 on the right side:
x = 22√2 / 2
This simplifies to:
x = 11√2
