Answer:
209.96
Step-by-step explanation:
we know that the circumference of the circle is equal to
C = ![\pi D](https://tex.z-dn.net/?f=%5Cpi%20D)
we have
![D = 64 ft](https://tex.z-dn.net/?f=D%20%3D%2064%20ft)
substitute would be
![C = \pi (64) = 64\pi ft](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20%2864%29%20%3D%2064%5Cpi%20ft)
assume that ![\pi = 3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D%203.14)
64![64\pi = 64 * 3.14 = 200.96 ft](https://tex.z-dn.net/?f=64%5Cpi%20%20%3D%2064%20%2A%203.14%20%3D%20200.96%20ft)
3x=4x-9
x=9
x-2.25=6.75
Tanya spent $9 on each item; Tony spent $6.75 on each of his items.
Answer:$3334.5
Step-by-step explanation:
A=p(1+r/100)^n
A=1400(1+7.5/100)^12
A=1400(1.075)^12
A=1400×2.381
A=$3334.5
