√ 70 lies between two numbers that each
have one decimal place.
Work out these two numbers.

The decimal numbers where ✓70 lies between will be 8.3 and 8.4.

Firstly, in order to solve the question, we need to know the value of the square root of 70. This will be ✓70 = 8.36.

Based on the above values, it can be seen that the decimal numbers which 8.36 lies between will be 8.3 and 8.4. Therefore, the correct option is 8.3 and 8.4.

8.3 and 8.4

Step-by-step explanation:

sqrt(70) will be in between 8 and 9, because 8^2 is 64 and 9^2 is 81, and 70 is in between these 2 numbers.

Now that we know that, we can test out the numbers between 8 and 9 whose square is closest to 70:

8.1^2 = 65.61

8.2^2=67.24

8.3^2 = 68.89

8.4^2 = 70.56

We know that sqrt(70) lies 8.3 and 8.4, because 70 is between 8.3^2 and 8.4^2

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
