3,628,800 ways can they arrange themselves in the shuttle, If 10 friends are going to occupy 10 seats in shuttle on the way to the airport.
Step-by-step explanation:
The given is,
10 friends are going to occupy 10 seats in shuttle on the way to the airport
Step:1
No. of friends - 10
No.of seats in space shuttle - 10
Formula to calculate the no. of ways to arrange,
............................(1)
Where, n - Positive integer
Step:2
From given, n = 10
Equation (1) becomes,
= 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
= 3628800
= 3628800 ways
Result:
3,628,800 ways can they arrange themselves in the shuttle, If 10 friends are going to occupy 10 seats in shuttle on the way to the airport.
Answer: See steps and explanation below. The value 5 makes the equation true.
9(3x - 16) + 15 = 6x - 24 Distributive Property
27x - 144 + 15 = 6x - 24 Combine like terms
27x - 129 = 6x - 24 Subtract 6x from both sides
21x - 129 = -24 Add 129 to both sides
21x = 105 Divide both sides by 21
x = 5 Answer!
X= 5
To find the side a we will use the Pythagorean Theorem:
<span><span>a2</span>+<span>b2</span>=<span>c2</span></span>
After substituting <span>b=12</span> and <span>c=13</span> we have:
<span><span>a2</span>+<span>122</span>=<span>132</span></span><span><span>a2</span>=<span>132</span>−<span>122</span></span><span><span>a2</span>=169−144</span><span><span>a2</span>=25</span><span><span>a=5</span></span>
