The possible outcomes are there on Ryan's first turn flipping two cards is
<h3>What are cards?</h3>
The cards are 52 in number in which 13 cards are different. Each card is four in quantity.
Ryan is playing a multiplication game with a pile of 26 cards, each with a number on them.
Each turn, he flips over two of the cards and has to multiply the numbers.
The number of ways in which two cards can be selected from 26 cards, at the same time. The order of those are important.
Then, the number of possible outcomes on each flip of two cards
= 26 p(2)
= 26 x 25
=650
Thus, the possible outcomes are there on Ryan's first turn flipping two cards.

1/2 x 6 = 3
3 x 8 = 24
24/6 = 4
4 - 1 = 3

Answer:Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.

Answer:
Step-by-step explanation:
Let the speed of the car is c and speed of the plane is p.
<h3>We are given:</h3>
The speed of the plane is 7 times the speed of the car
The distance traveled is
The time difference to travel this same distance is 3 hours.
<h3>We know that:</h3>
- d = ts, where d- distance, t- time, s - speed
Find the time for car and plane and their difference.
<h3>Car</h3>
<h3 /><h3>Plane</h3>
- t = d/s = 315/p = 315/(7c) = 35/c
<h3 /><h3>The difference</h3>
<u>Solve it for c:</u>
- (315 - 45)/c = 3
- 270/c = 3
- c = 270/3
- c = 90 km/h
Now find the speed of plane:
