Answer:
Step-by-step explanation:
7/8=0.875
0.875 x 40= 35
Therefore, Kris has finished 35 questions.
Hope this helps.
4^4x = 8
since 4 = 2^2 & 8= 2^3
so we can write the equation as
(2^2)^4x = 2^3
2^8x =2^3
sp ,, 8x = 3
then x = 3/8
270(pi/180)=3pi/2=theta
theta*radius=arc length
(3pi/2)(14)=65.9734 yds
You would multiply 9x___ whatever the other number is witch is 4
