Answer:
B, 25.9 pi
Step-by-step explanation:
360 - 170 = 190
r= 7
pi 7^2 = 49 pi
49/2 = 24.5 pi
24.5 + 1.4 = 25.9 pi

Step-by-step explanation:
no. mike added the two fractions incorrectly by not changing them to common denominators.
the correct answer:
4/7 + 1/4 = ?
4/7 = 16/28 (multiply both the numerator and denominator by 4 to get the common denominator fraction)
1/4 = 7/28 (multiply both the numerator and denominator by 7 to get the common denominator fraction)
16/28 + 7/28 = 23/28 (only add the numerators!!)
mike covered <u>23/28 </u>of the distance from his home to the library. (always check to see if your answer can be simplified)
Answer:
y = 129 degrees
Step-by-step explanation:
180 - 51 = 129
Answer:
Step-by-step explanation:
By the polygon exterior angle sum theorem, all the exterior angles of a polygon add up to equal 360 regardless of the number of sides it has. That means that 82 + 150 + b = 360 so
b + 232 = 360 and
b = 128
