Ok...so u have 4 people sharing this plan...they each pay for their own data..however, the $ 90 flat rate is split between them equally.
90/4 = 22.5....so each of them pay 22.50 each for the flat rate.
so John's equation is : 22.5 + 0.25x = 147.50
Answer: 267.947 (or 267.95) inches^3
Step-by-step explanation:
The formula for the volume of a sphere is
.
To find your radius (r), divide the diameter of 8 inches by 2. <em>The radius is 4 inches.</em>
Plug in your numbers to the volume equation to get
. The first step is to cube 4 (4*4*4) to get <em>64</em>. Now your equation is
.
Multiply 3.14 and 64 to get <em>200.96</em>. The equation is now
or
.
Multiply the numerators (4 * 200.96) and denominators (1 * 3) to get a final equation of
.
Finally, divide 803.84 by 3 to get the final answer of 267.947 in^3.
55x + 10 = 57x....where x = number of months
10 = 57x - 55x
10 = 2x
10/2 = x
5 = x.....they will cost the same at 5 months...they will each cost $ 285 at 5 months
APR=(1+r/12)^(12)-1
APR=(1+0.16÷12)^(12)−1
APR=0.172×100
APR=17.2%
