Answer:
Option a.
The approximate measure, in degrees, of the central angle is
Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to
we have
assume
substitute
step 2
Using proportion
Find the central angle of the circle by and arc length of 10 m
Remember that the circumference of a circle subtends a central angle of 360 degrees
so
Let
x -----> the measure of the central angle in degrees
You would just put 0 for y and then solve each of the equations in the parentheses so the answer would be x=5, x=-2/5
The first term is -43.
Explanation:
an = a + (n - 1)d
a12 = a + 11d = 56, first equation
a21 = a + 20d = 101, second equation
Subtract the second equation from the first equation, cancelling +a and -a
11d - 20d = 56 - 101
-9d = -45
d = 5
Subtitute d into the first equation
a + 99 = 56
a = -43
a refers to the first term, hence the first term is -43.
Answer:
answer: $5
Step-by-step explanation:
If your asking whats 100% of $5 then $5 is the answer because $5 is 100% of $5
