Answer:
$65.325 or $65.33
Step-by-step explanation:
When looking for a percentage in a number, you want to multiply that number by the percentage. Remember that all percentages are to the hundreth power, or 0.00. So if you want to find 30% of 50.25, you multiply it by 0.30 or 0.3. After calculating that you will come up with 15.075 as the percentage. Since the store is marking the price up, you add it to the original price. So your equation is 50.25 + 15.075 =?. After calculating that, you get the answer 65.325. That is only half of your answer though because, when dealing with money, you always round to the nearest hundredth. So when you round 65.325, you get 65.33 which should be the correct answer.
Answer:
the answer is 29
Step-by-step explanation:
a^2 + b^2 = c^2 (btw ^ means to the power)
a and b are the legs. c is the hypotenuse
21^2 + 20^2 = c^2
441 + 400 = 481
then we have to square it.
the square root of 481= 29.
btw the hypotenuse is always going to be bigger than the legs.
hope it helps!! btw it is right!
