His average is 80%. You take the two scores add them up and divide by the number of scores.
Answer = 13$
Explanation = This would mean each taco would be roughly 1.3$ since 4/3=1.333, so 1.3x10=13$
5x70=5x7tens.
60x4=6tensx4.
7x30=7x3tens.
90x3=9tensx3.
The areas of a. circle is

the diameter is 2 times the radius, therefore
π (13/2)^2=132.665
Answer: about 132.7 in^2
Answer:
x = 2* pi* n
Step-by-step explanation:
cos(2x) cos(x) + sin(2x) sin x =1
We know cos(s) cos(t) + sin(s) sin(t) = cos(s - t)
Using s =2x and t = x
cos (2x-x) =1
cos (x) =1
We know this occurs at 0, 2pi, 4 pi etc
x = 2* pi* n where n is an integer
