Let the radius of circle a be R, then the radius of circle b is 3R.
The circumference of circle b is 2π*(radius b)=2π*3R= 6πR.
The circumference of circle a is 2π*(radius a)=2π*R=2πR.
This means that one complete revolution of circle a covers 2πR distance. Since there is a total 6πR distance in circle b:
Circle a revolves in total 6πR/2πR=3 many times.
Answer: 3
Average = total sum of values/ number of values, so work backwards.
Let x = unknown number.
(18 + 24 + 32 + x)/4 = 24
=74+x = 96
=x=22
She must score 22 in the next game to have an average of at least 24 points.
Simple, to make fractions a decimal all you do is divide the numerator by the denominator. In this case we have 7/10, 7 is the numerator and 10 is the denominator. 7÷10=0.7, So, 7/10 in decimal form is 0.7
Answer: the parabola that opens up. then goes through (negative 1, 4), and has a vertex at (1, 0), and goes through (3, 4).
