<h3>Answer: (-1, 1)</h3>
=========================================================
Explanation:
The rotation rule we use is
The x and y coordinates step places, then the second coordinate (after the swap) changes in sign from positive to negative, or vice versa.
For example, the point (5,7) rotates to (7, -5). As another example, (2,-1) becomes (-1, -2). As another example, (-9,4) becomes (4,9).
----------------------------------
In our case, the point (-1,-1) will rotate to (-1, 1)
Note: A 270 degree counterclockwise rotation about the origin is the same as a 90 degree clockwise rotation about the origin. Refer to the diagram below.
Answer:
40%
Step-by-step explanation:
A percent is;
It is given that Jolie the 75 dodgeballs in total, hence the whole is 75. It is also given that 30 of the dodgeballs hit the target, so the part is 30. Now all one has to do is solve for "x".
Simplify by dividing the numerator and denominator by 15.
Now the equation is;
Typically, one would solve a proportion by doing cross products, but in this case, it is easier to think about it intuitively. Since 5 is a factor of 100 (5 * 20 = 100), then all one has to do is multiply by 20 to get the answer (on the numerator).
x = 40
Given data:
Assume the number is x.
The given expression is,
Thus, the given number is 44.
