Answer:
38 mpg
Step-by-step explanation:
Initial efficiency = 39 mpg
Initial speed = 40 mph
Final speed = 50 mph
The efficiency drop between 40 mph and 50 mph is given by:
![E_d = 0.1 \frac{mpg}{mph}*\Delta V](https://tex.z-dn.net/?f=E_d%20%3D%200.1%20%5Cfrac%7Bmpg%7D%7Bmph%7D%2A%5CDelta%20V)
The total efficiency drop from 40 to 50 mph is:
![E_d = 0.1 \frac{mpg}{mph}*(50-40)mph\\E_d = 1\ mpg](https://tex.z-dn.net/?f=E_d%20%3D%200.1%20%5Cfrac%7Bmpg%7D%7Bmph%7D%2A%2850-40%29mph%5C%5CE_d%20%3D%201%5C%20mpg)
Therefore, the efficiency at 50 mph is:
![E_{50} = E_{40} -E_d\\E_{50} = 39 -1\\E_{50} = 38\ mpg](https://tex.z-dn.net/?f=E_%7B50%7D%20%3D%20E_%7B40%7D%20-E_d%5C%5CE_%7B50%7D%20%3D%2039%20-1%5C%5CE_%7B50%7D%20%3D%2038%5C%20mpg)
Answer:
3x + 1y = $163
2x + 3y =$174
Step-by-step explanation:
Adult tickets to space amusement park cost x dollars children’s tickets cost y dollars.
Henson family bought 3 adults and 1 child's tickets for $163
x + y = 163
3x + 1y = 163
The Garcia family bought 2 adults and 3 child’s ticket for $174.
x + y = $174
2x + 3y = $174
Therefore the equations representing both families cost are
Henson family
3x + 1y = $163
Garcia family
2x + 3y = $174
The linear equation that represent the left balance of sanjaya’s y after visiting x number of days is:
y = 10x + 500.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
From the data given, we have that:
- The y-intercept is of 500.
Hence the balance is given as follows:
y = 10x + 500.
