Answer:
7
Step-by-step explanation:
The easiest way to tell if a number is rational or not is to attempt to express it as a fraction. If you can, then the number is rational. If not, then the number is irrational. All integers are rational numbers, because they can be written as a fraction (for example, the integer 8 = 8/1). But numbers like pi or sqrt(2) cannot be written as a fraction and are not rational.
51*32/102=32/2=16.
Therefore, Raina will need 16 cans to cover the court.
The pond will be full by the end of the day in 93 days.
<h3>Linear system</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
The pond can hold 400 water liters.
y = 3.915(1.106)x is an expression.
<h3>To find </h3>
The pond will be full by the end of the day.
<h3>How many days it will take?</h3>
Let x be the day and y be the hold of water.
When pond can hold 400 liters of water the x will be
400 = 3.915×1.106x
400 = 4.33 x
x = 92.37 ≈ 93
Thus, the pond will be full by the end of the day in 93 days.
