what is d over 12 plus 7 times d over 12 equal
let me break it down for you, 7 days (d) = 1 week (w) 7(d) =1(w) 7(d) X 3 =21(d) =3(w) Answer: 21 days to 3 weeks.
Basic formula: D=rt Solve for rate: r=D/t Time must be in hours; 5 min * 1 hr/60 min = .08333 hr r=7mi/.0833hr = 84 MPH (rounded) Alternative method: There are 12 x 5 min in an hour so 12 x 7 = 84 mph
Circumference of a circle is equal to 2(pi)r with r being the radius, or (pi)d with d being the diameter. If we use (pi)d, with d being equal to 7 and (pi) being equal to 3.14159, we get that the circumference is 21.9911485751 inches. This can be rounded to 22 inches.3.14159 * 7in = 21.9911485751in
If you are seeking d more than 7, you'll need to add d to 7. We find that d + 7 is d more than 7. In this case, d is a variable, but the math is direct and correct.
