Answer:
The amount of money in his paycheck was $ 225.
Step-by-step explanation:
Given that Li put $ 75 into his savings account, and said money was 1/3 of his paycheck, to determine which equation could be used to find the amount of money, p, in dollars, on his paycheck, the following reasoning must be performed mathematical:
75 / (1/3) = P
75 / 0.333 = P
225 = P
Thus, the amount of money in his paycheck was $ 225.

Answer:
n=-11
Step-by-step explanation:
Since -15 is 4 less than -11, it would be -11.
Hope this helped. :)
To perform a 90° rotation clockwise around the origin, you take the coordinates of the point A(x, y) and transform them to A'(y, -x). Since 180° and 270° are both "steps" of 90°, we can do this in succession and achieve our goal.
1) (5, 2) 90° = (2, -5) [(y, -x)]
2) (5, 2) 180° = two 90° turns = (2, -5) rotated 90° = (-5, -2)
3) (5, 2) 270° = three 90° turns = (-5, -2) rotated 90° = (-2, 5)°
4) (-5, 2) 90° = (y, -x) = (2, 5)
5) (-5, 2) 180° = two 90° turns = (2, 5) rotated 90° = (5, -2)
6) (-5, 2) 270° = three 90° turns = (5, -2) rotated 90° = (-2, -5)
7) (-2, 5) 90° = (y, -x) = (5, 2)
8) (5, -2) 180° = (y, -x) with another 90° turn = (-2, -5) rotated 90° = (-5, 2)
Answer:
63.6 m^2
Step-by-step explanation:
A = (pi)r^2
r = d/2 = 9 m / 2 = 4.5 m
A = (3.142)(4.5 m)^2
A = 63.6 m^2
