A chord can contain at most how many diameters

Answers

A cord links any two points on a circle.

The greatest distance between two points on a circle is the length of the diameter.

Hence a chord can contain at most one diameter.

!!!!!!!!50 POINTS!!!!!!!!!!!!Suppose a square has a side length by the expression x+5/8x. What is the perimeter of the square?

Answers

This is equal to (x -5)(x - 5), or (x - 5)². 
Therefore, using the formula given above, the side's length is equal to (x - 5). 

Muliply that by four to obtain the perimeter. 

4(x - 5) = 4x -20. 

For the second problem, disregard the brackets since there are no other operations besides subtraction and addition. 

So it would become 3x^4 -x + 2 + 9x^5 - x² + x. 

Now simplify everything and rewrite it in decreasing terms of power, 

9x^5 + 3x^4 - x² + 2. 

The ratio of boys to girls in a school is 5:4. if there are 180 students, how many girls are there?

Answers

Salutations!

The ratio of boys to girls in a school is 5:4. if there are 180 students, how many girls are there?

Let the number of girls and boys be 'x'.

5x + 4x = 180

Add 5 and 4

9x = 180

x = 20

Now, multiply the ratios by 20.

Boys = 20 × 5 = 100

Girls = 20 × 4 = 80.

There were 80 girls.
