A7-hour class will be divided into equal sessions of 7/5 (change it into a mixed number) hours. how many sessions will be needed

A 7 hour class is going to be divided into 7/5 hour long sessions. 7/5 when you divide (7÷5) = 1.4 To change 1.4 into a mixed number, we know that 0.4 is equal to four tenths or 4/10, thus the mixed number is 1 4/10. To find out how many sessions will be needed, we need to divide (7 ÷ 1 4/10) When this operation is done, your answer is 5. Therefore, 5 sessions will be needed.

Given:

The radius of the circle XY is XY = 11.4 in

The length of ZY is 15.2 in

The length of XZ is 19.6 in

We need to determine whether YZ is a tangent to the circle X.

Is YZ tangent to the circle X:

We shall determine whether YZ is a tangent to the circle X by using the Pythagorean theorem.

Thus, we have;

Substituting the values, we have;

Simplifying, we get;

Since, both sides of the equation are not equal, thus, YZ is not a tangent to the circle X.
