Answer:
62 miles
Step-by-step explanation:
The formula for average is given as
Sum of values / Number of values
Let x = miles on the last day
Hence
48 + 51 + 59 + x/4 = 55
Cross Multiply
= 158 + x = 220
x = 220 - 158
x = 62
Therefore, he needs to bike 62 miles on the last day so that his average (mean) is 55 miles per day.
Acute
two of the angles are acute and the other is right.
The area is about 1590 and the circumference is about 141
just sum the 2 power
6 + 2 = 8
x^8
true
