He has seven models because 21 divided by 3 is seven
Answer:
J=16
Step-by-step explanation:
You have to move all the number to the opposite side of the variable.
j-12=4
j=4+12
j=16
Area of Circle = πr^2
Since we know that r=6.3:
π(6.3)^2=39.69 π=124.690
So, the area would be 124.690.
Xn = ar^(n-1)
n = term to find = 6
a = 1st term = 72
r = common ratio = 0.5
now we sub
x6 = 72 * 0.5^(6-1)
x6 = 72 * 0.5^5
x6 = 72 * 0.03125
x6 = 2.25 <===
