Question
Estimate the value of the expressions to the nearest whole number.
5+
Hint:
Hint:
For rounding off a number to the nearest whole number, we have to look at the first digit after the decimal point. If this digit is less than 5 i.e. 1, 2, 3 or 4 then we don’t have to do anything, but if the digit is 5 or greater i.e 5, 6, 7, 8, 9 we must round up. For example, the nearest whole number to the number 2.8 is 3 while in the case of 2.45, it will be 2.
The correct answer is: 12
Let’s say x = 5 + and y = which means x = 5 + y
Let’s factorise the number inside the square root i.e 50
Put the factorised in the square root
is an irrational number and its approximate value is 1.41421…
Now, x = 5 + y
Putting the value of y
As the digit after the decimal point is 0 which is less than 5. So, the nearest whole number will be 12.
Final Answer:
Hence, the nearest whole number of 5 + is 12.

In economics, the linear function is popular. It is appealing because it is straightforward and straightforward mathematical. Moreover, it has numerous useful applications.
A linear function consists of one independent variable and one dependent variable. 'y' is the dependent variable, while 'x' is the independent variable. In economics, the linear function is popular. It is appealing because it is straightforward and straightforward mathematical. Moreover, it has numerous useful applications. For example, linear functions have graphs that are straight lines.
A linear function's domain and range are typically a set of real numbers. However, there is one exception: if the function is constant (for example, f(x) = 2), the range is constrained to that constant.
