Of the 20 sandwiches prepared by Ali, Ben and Carla, Ali made a total of A) two sandwiches
Information of the problem:
- Total of sandwiches: 20
- Ali = x
- Ben = 3x
- Carla = 2*(3x)
To solve this problem we have to state the equation using the information of the problem:
Total of sandwiches = Ali + Ben + Carla
20 = x + 3x + 2*(3x)
20 = x + 3x + 6x
20 = 10x
x = 20 / 10
x = 2
Substituting the (x) value into the information of the problem we get:
Ali = 2 sandwiches
Ben = 3*2 = 6 sandwiches
Carla = 2*(3*2) = 2*6 = 12 sandwiches

In this situation, you have to use the equation
T = 2π√L / 32
We need to find L so we have:
T / 2π = √L / 32
(T / 2π) ^ 2 = L / 32
L = 32 * (T / 2π) ^ 2
Substitute the values:
L = 32 * (8.72 / (2 * (3.14))) ^ 2
L = 61.69694511 feet
L = 62 feet
So the Answer is
L = 62 feet
Answer:
243
Step-by-step explanation:
3*3=9*3=27*3=81*3=243*3 etc
The answer is 12.3 inches
<em><u>The correct answer is 60 seats on the left side</u></em>, but you might also want to know how I got that answer . . .
Let's say, n = number of rows
Since we know the airplane has an equal number of rows on the right side as it does on the left side, then we can mathematically show that:
number of sears on the right side = 3n = 90 seats
number of sears on the left side = 2n = ? seats
3n = 90
n = number of rows = 90/3 = 30 rows
Thus:
2n = 2(30) = <u><em>60 seats on the left side</em></u>
<em>as for how many seats all together, just add . . 90 + 60 = 150 seats total</em>
