Answer:
He sold 100 rackets for $ 20
Step-by-step explanation:
To start, we have to make 2 equations, one that represents the number of rackets and the other the money
x + y = 500
x * 20 + y * 45 = 20000
we clear x in the first equation
x + y = 500
x = 500 - y
we replace x in the second equation with (500 - y)
x * 20 + y * 45 = 20000
(500 - y) * 20 + y * 45 = 20000
10000 - 20y + 45y = 20000
-20y + 45y = 20000 - 10000
25y = 10000
y = 10000/25
y = 400
we replace x in the first equation with the value obtained
x = 500 - y
x = 500 - 400
x = 100

Answer: First Option
Step-by-step explanation:
The formula to calculate the volume of a cylinder is:
Where d is the diameter of the cylinder and h is the height.
Notice that the term d is squared. This means that to increase the volume of a cylinder it is more efficient to increase its diameter as well. Therefore, look for the cylinder with the largest diameter among the options.
The first cylinder is 90 ft in diameter and 40 ft in height and its volume is
You can verify that it is the tank that has the highest volume

Answer:
√3
Step-by-step explanation:
This is a 30-60-90 triangle, in which the side measurements will follow the rule of 1, √3 , 2.
Remember, the smallest side is the one opposite the 30° angle (1), while the hypotenuse is the one opposite the 90° (2).
In this case, the given smallest side measurement is 1. This means that q is 1 x √3 = √3.
√3 is your answer.
