Set up multiplication/division to cancel out units that you do not need for your final answer and introduce units that you do.
You want your answer in the form km/hr and you are starting with m/s so:
(12m/s)(km/1000m)(60s/min)(60min/hr)=43.2km/hr
The car is traveling at 43.2 kilometers per hour.
Answer:
c = 55 . . . . (no units for cost are given in your problem statement)
Step-by-step explanation:
"t is the number of tickets" and "Marci bought 20 tickets", so we conclude t=20. Putting that value into the equation and doing the arithmetic, we find ...
c = 2.75·20 = 55
_____
We don't know if this is pennies or pounds, dollars or rupees or pesos or euros. No monetary units are mentioned in the problem statement given here.
Use Pythagorean theorem.
a^2 + b^2 = c^2
D.
21^2 + 72^2 = 75^2
441 + 5184 = 5625
3.75* .92= $3.45
2.1* 1.10= $2.31
$3.45
+ $2.31
_______
$5.76
