Answer:
B.62.8 inches
Step-by-step explanation:
just multiply the diameter by pi to get the circumference
20 x 3.14= 62.8
R=23 because its slope the formula is Y-Y/X-X
You need k by itself, so the only way to do that is to divide both sides by 5
Answer:
C.255
Step-by-step explanation:
To find the answer to this question, we can 14 by 5 and subtract it from the total of 325.
14*5=70
325-70=255
<u>The correct answer is C. 255</u>
Hope this helps!
Answer:
y = -1/2x + 1/2
Step-by-step explanation:
perpendicular lines have slopes that are opposite signs and reciprocal
therefore, use m=-1/2 and point (9, -4) to complete the equation by finding 'b' (the y-intercept)
-4 = -1/2(9) + b
-4 = -9/2 + b
-4 + 9/2 = b
-4 + 4
= b
b =
