Answer:
Step-by-step explanation:
When the three cards are removed, the sample space becomes 49.
Probability of a heart = 13/49. No hearts were removed from the deck.
Probability of a king = 3/49. One king was removed from the deck.
Probability of the 10 of hearts = 1/49. There's only one 10 of hearts in the deck, and it was not removed.
Probability of a black face card = 3/49. Three of the black face cards were removed, so all that is left are the king, queen, and jack of clubs.
Probability of an ace OR a queen = 7/49 = 1/7. There are 3 queens and 4 aces remaining in the deck.
Answer:
20x+25y
Step-by-step explanation:
First, let's solve for the cars. For one car, a wash and a wax would cost $20, but instead, we're solving for X cars. so instead of 1(20), we would have x(20), which we can simplify to 20x. Now for the trucks, we're going to add the 10 and the 15, which is 25, for one car, and 25y for Y cars.

Answer:
D. $53.76
Step-by-step explanation:
When calculating discounts and sales tax, you need to first change your percentages to decimals by dividing each by 100:
20%/100 = 0.2
5%/100 = 0.05
Since the shoes are at a 20% discount, you will only pay 80% of the original amount, or: $64.00 x 0.8 = $51.20
However, you also need to pay a 5% sales tax, in addition to the sales price, so you can take the discounted amount and multiply:
$51.20 x 1.05 = $53.76 total cost
