32. 16= 2^4 --->2x2x2x2=16
36. 9/16= (3/4)^2 --->3/4x3/4=9/16
Answer:
C. 
Step-by-step explanation:
Recall: SOHCAHTOA
Thus,
Reference angle = 28°
Adjacent = 15
Hypotenuse = 17
Plug in the values
First Question
circumference = pi * diameter
diameter = circumference/pi = 94.2 in./3.14 = 30 in.
The wheels have a 30-inch diameter.
-----------------------------------------------------------------------
Second question
The area of a circle: area = pi * r^2
radius = diameter/2 = 94.2 in./2 = 47.1 in.
area = pi * r^2 = 3.14 * 47.1 in. * 47.1 in. = 6966 in.^2
Answer: 6966 in.^2
-----------------------------------------------------------------------
Third question
The piece of felt has a width equal to the diameter of the wheel. The length has to be the same as 4 diameters.
4 * 94.2 in. = 376.8 in.
Answer: 376.8 in.
Answer:
-169
Step-by-step explanation:
We want to isolate v.
Method 1: subtract 40 from both sides, obtaining 169 = -v. Then change the sign of both sides, arriving at v = -169.
Method 2: Add v to both sides. Then v + 209 = 40.
Now subtract 209 from both sides, obtaining -169.
