*3 is larger than 2 by 1

meaning, if her mom has 6 songs, then she will have 7

Find the center of a circle whose end points of a diameter are A (-5,6) and B (3,4)

victus00 [196]

<u>Answer:</u>

(-1, 5)

<u>Step-by-step explanation:</u>

The center of a circle is the midpoint of the diameter.

So we have to calculate the midpoint of the diameter, using this formula:

midpoint = ( $\frac{x_{2 }+x_{1} }{2}$ , $\frac{y_{2} + y_{1} }{2}$ )

= ( $\frac{3 + (-5)}{2}$ , $\frac{4 + 6}{2}$ )

= (-1, 5)

∴ The center of the circle lies at the point (-1, 5).

Which fraction is less than 1 chose all of the correct answer, and explain why you chose and write it down and explain your answ

EleoNora [17]

Answer:

$(3/4)$ and $(2/3)$ .

Step-by-step explanation:

For a fraction of the form $(p / q)$ , the number in front of the division ( $p$ ) is the numerator. The number after the division ( $q$ ) is the denominator.

$\begin{aligned} \frac{p}{q} \quad \genfrac{}{}{0}{}{(\text{numerator})}{(\text{denominator})}\end{aligned}$ .

A positive fraction $(p/q)$ ( $p,\, q > 0$ ) is less than $1$ as long as the numerator $p$ is smaller than the denominator $q$ (that is, $p < q$ .) The reason is that as long as $p,\, q > 0$ :

$\begin{aligned} & \frac{p}{q} < 1 \\ \iff & (q)\, \left(\frac{p}{q}\right) < (q)\, (1) && (\text{given that $q > 0$}) \\ \iff & p < q\end{aligned}$ .

For example, in the fraction $(2/3)$ , $2$ is the numerator while $3$ is the denominator. Both the numerator and the denominator are positive, while the numerator $2\!$ is smaller than the denominator $3\!$ . Therefore, $(2/3)$ would be less than $1$ .
