Basically, you'd do:
0.2 * 52 (0.2 = 20%, 21% = 0.21)
Your Answer:
10.4
Answer:
-2/3x + y = -7
Step-by-step explanation:
So, y = 2/3x - 7 is the slope-intercept equation. Now, we need to turn it into the standard equation of a slope.
Standard equation --> Ax + By = C
y = 2/3x - 7
-2/3x -2/3x
----------------------
-2/3x + y = -7 --> this is your equation in standard slope form.
Answer: shameeka sold 20 hamsters to the store.
Step-by-step explanation:
Let x represent the number of hamsters that shameeka sold to the store.
Let y represent the number of hamsters that the pet store had initially.
Shameeka sold her hamsters to a pet store. This doubled the number of hamsters in the store. It means that
x + y = 2y
x = 2y - y
x = y
Then the store got six more hamsters. If the pet store has 46 hamsters now, it means that
2y + 6 = 46
2y = 46 - 6
2y = 40
y = 40/2
y = 20
Since x = y, then
x = 20
60 people have ridden the wheel in 30 minutes
The time is given as:
The number of seats on the wheel is given as:
The number of people on a seat is given as:
Every minute a seat exits the platform.
This means that, 2 people exit the platform every minute
So, the number (n) of people that exit the platform after 30 minutes would be:
This gives
Multiply
Hence, 60 people have ridden the wheel
