Answer:
Step-by-step explanation:
This is a right triangle problem. The reference angle is x, the side opposite the reference angle is 32, and the hypotenuse is 58. The trig ratio that relates the side opposite a reference angle to the hypotenuse is the sin. Filling in accordingly:
Because you are looking for a missing angle, you will use your 2nd button and then the sin button to see on your display:
Within the parenthesis enter the 32/58 and you'll get your angle measure. Make sure your calculator is in degree mode, not radian mode!!!

Answer: -5 < x < 2</h3>
Explanation:
The expression -2x means -2 times x. To undo this, we divide all parts of the inequality by -2. Dividing by a negative number will flip the inequality sign. We go from "less than" to "greater than"
-4 < -2x < 10
-4/(-2) > x > 10/(-2) .... inequality signs flip
2 > x > -5
-5 < x < 2
This unknown number x is between -5 and 2. It cannot equal -5. It cannot equal 2.
Hey there! :D
So, what we need to do is make a fraction that has a denominator of 100. This is the simplest route to take.
330/500
If you took one zero away from each side, you will get an equivalent fraction:
33/50
Multiply both side by 2 to get to 100.
33*2=66 50*2=100
66/100
So, 66% percent ornament the parking lots were filled.
I hope this helps!

33% depending on if your numbers is the same as mine
15(1 + n/100) = 75(1 - n/100)
15 + 0.15n = 75 - 0.75n
0.15n + 0.75n = 75 - 15
0.9n = 60
n = 60/0.9 = 66 2/3%
6% of n = 0.06 x 66 2/3 = 4
