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.
<span> Euler's Formula : </span><span>V - E + F = 2
</span><span>Given that F = 10 and E = 24
V - 24 + 10 = 2
V - 14 = 2
V = 16

Answer:
c+10+2c+c=220
Step by step Explanation:
Let, a= number of adult's tickets sold
s= number of senior's tickets sold
c= number of children's tickets sold
a=c+10
and, s=2c
Now, a+ s+ c=220
c+10+2c+c=220
4c=210
c=52.5
Note: If there were 222 tickets the answer will be 53
Well his salary is $40,000 dollars.
$72,750 - $40,000 = $32,750
This means that 5% of the value of investments he had sold was equal to $32,750.
The stockbroker sold $655,000 worth of investments.
Answer:
Step-by-step explanation:
Consider triangle ACD. This triangle is isosceles triangle, because AD = DC. Angles adjacent to the base AC are congruent abgles, so
The sum of the measures of all interiror angles in the triangle is always 
then
Angles ADC and BDC are supplementary angles (add up to 
), then
Consider triangle BCD. This triangle is isosceles triangle because BC = DC. Angles adjacent to the base BD are congruent abgles, so
The sum of the measures of all interiror angles in the triangle is always then
