Answer:
Option 3.
Step-by-step explanation:
Let r be the number of rides Connor can go on.
The price of admission to the carnival is $4.50, and each ride costs an additional 79 cents.
Total cost of admission and r rids is
![\text{Total cost}=4.50+0.79r](https://tex.z-dn.net/?f=%5Ctext%7BTotal%20cost%7D%3D4.50%2B0.79r)
Connor can spend at most $16.00 at the carnival. So, total cost must be less than or equal to $16.00.
![4.50+0.79r\leq 16.00](https://tex.z-dn.net/?f=4.50%2B0.79r%5Cleq%2016.00)
Subtract 4.50 from both sides.
![4.50+0.79r-4.50\leq 16.00-4.50](https://tex.z-dn.net/?f=4.50%2B0.79r-4.50%5Cleq%2016.00-4.50)
![0.79r\leq 11.50](https://tex.z-dn.net/?f=0.79r%5Cleq%2011.50)
Divide both sides by 0.79.
![r\leq \frac{11.50}{0.79}](https://tex.z-dn.net/?f=r%5Cleq%20%5Cfrac%7B11.50%7D%7B0.79%7D)
![r\leq 14.55](https://tex.z-dn.net/?f=r%5Cleq%2014.55)
The maximum number of rides he can go on is 14. Therefore, the correct option is 3.
0.135135... * 1000 = 135.135....
0.135135...* 1 = 000.135135...
subtract 999 = 135
so fraction is 135/999
$7.40/8 = $0.93 per pound
$5.38/4 = $1.35 per pound
The 8-pound bag of dog food is a better buy.
Answer:
3.2
Step-by-step explanation:
x² + xy = 20
Take the derivative with respect to time:
2x dx/dt + x dy/dt + y dx/dt = 20
(2x + y) dx/dt + x dy/dt = 20
Given x = -5, y = 1, and dx/dt = -4:
(2(-5) + 1) (-4) + (-5) dy/dt = 20
(-10 + 1) (-4) − 5 dy/dt = 20
36 − 5 dy/dt = 20
5 dy/dt = 16
dy/dt = 3.2
