Answer:
3.14 x 14 = 42 + 1.96 = 43.96 (units) sq. or cm^2
Step-by-step explanation:
We remember that; for pi multiplications;
10 x 3 = 30
4 x 3 =12 = 42
That decimals 0.14 x 10's =1.4
That decimal 0.14's x 4 units = 0.56
= (+ 1.4 = 0.56) + 42 = 43.96

Answer:
Owen can afford to keep and drive the car for 4 days.
Step-by-step explanation:
The total owing on the car rental is R(d) = ($77.25/day)d + ($0.12/mile)m ≤ $330. Substitute 1 for d (that is, the rental is for 1 day) and 175 for m:
R(d) = ($77.25/day)(d days) + ($0.12/mile)(175 miles) ≤ $330
= $77.25d + $21 ≤ $330
This simplifies to $77.25d + $21 ≤ $330, or
$77.25d ≤ $309
Solving this by dividing both sides of the above equation by $77.25, we get
d = ($309)/($77.25) = 4
Owen can afford to keep and drive the car for 4 days.
