Answer:
<u><em>3</em></u>
Step-by-step explanation:
The base of it: 5*14 = 70
The left side: 14*5 = 70
The right side: 14*5 = 70
The two triangle sides are 7*12 = 84 cm^2
Answer: Median is 26,5 and modes are 24 and 29
Step-by-step explanation: In increasing order numbers are
22, 24 24, 25 , 28, 29 , 29 , 34. Because amount of number is even
median is (25 + 28) / 2 = 26,5 and modes are 24 and 29 because both
numbers exist twice

- Error (e) = 50 - 42 = 8 feet
- assumed value (a) = 42 feet
![\boxed{ \mathrm{ \% \: error = \dfrac{error}{assumed \: value} \times 100}}](https://tex.z-dn.net/?f=%20%5Cboxed%7B%20%5Cmathrm%7B%20%5C%25%20%5C%3A%20error%20%3D%20%20%5Cdfrac%7Berror%7D%7Bassumed%20%5C%3A%20value%7D%20%20%5Ctimes%20100%7D%7D)

Hello!</h2>
The answer is:
It will take 18 hours for the return trip.
<h2>
Why?</h2>
To calculate how long does it take for the return trip, we need to calculate the distance between it destination and the starting point.
We know that the ship sails at 15 miles per hour (mph) for 6 hours, so, calculating the distance we have:
![x=x_o+v*t\\\\x=0+15mph*6hours=90miles](https://tex.z-dn.net/?f=x%3Dx_o%2Bv%2At%5C%5C%5C%5Cx%3D0%2B15mph%2A6hours%3D90miles)
We know that the distance between the destination and the starting point is 90 miles, now, to calculate how long does it take the return trip, we need to use the motor speed rate which is equal to 5 miles per hour (mph), so, calculating we have:
![Distance=v*t\\\\t=\frac{Distance}{v}=\frac{90miles}{5mph}=18hours](https://tex.z-dn.net/?f=Distance%3Dv%2At%5C%5C%5C%5Ct%3D%5Cfrac%7BDistance%7D%7Bv%7D%3D%5Cfrac%7B90miles%7D%7B5mph%7D%3D18hours)
Therefore, we have that it will take 18 hours for the return trip.
Have a nice day!
