Explanation

To determine the quadrant, let's convert the angle to degrees:

8π/5 radians = (8 * 180°) / 5

= 288°

Since 288° lies between 270° and 360° (or -90° and 0° if considering the unit circle in a different manner), it falls in the:

4th quadrant

Explanation

To solve the equation:

5/6 ÷ 5/9

When dividing by a fraction, multiply by its reciprocal:

5/6 × 9/5 = 9/6

Simplify the fraction:

9/6 = 3/2

Explanation

To find the halfway point:

103 + 301 = 404

404 / 2 = 202

So, the correct answer is 202.

Explanation

A non-terminating, non-recurring decimal cannot be expressed as a fraction.

It is the key characteristic of an irrational number.

Explanation

In the 3rd quadrant, both the x and y coordinates are negative.

The point (-1, 2) has a positive y-coordinate, so it does not lie in the 3rd quadrant.

Explanation

A number is divisible by 8 if its last three digits form a number that is exactly divisible by 8.

For example, 4,320 is divisible by 8 because 320 ÷ 8 = 40 (a whole number).

Explanation

The harmonic mean is the reciprocal of the arithmetic mean of the reciprocals of the data points.

It is calculated as the inverse of the average of the inverses of the values.

Explanation

Explanation

1,5,9,13, ---- 40th

d=5-1=4 d=9-5=4 =1+(40-1)*4 =1+156 =157

U have to use the formula S=n/2 [2a+(n-1)d]

S=40/2[2(1)+(40-1)4]

S=20[2+(39)4]

S=20[156]

S=3160

Explanation

The number that is 200 more than 546 is:

546 + 200 = 746

So, 746 is 200 more than 546.
