Step-by-step explanation:

So we need to understand what is rational numbers?

Rational number which can be written under this form: \frac{x}{y} when x any are both integers and y\neq 0

The question here is : Which property would be useful in proving that the product of two rational numbers. In math, when we talk about the product of at least two number, it implies to the multiplication in the operation.

Here, only answer C: \frac{a}{b} *\frac{c}{d} = \frac{ac}{bd} with the condition b\neq 0 and    d \neq 0 and a, b, c and d are integers. Product of two integers is always an integer..

I’d make the spinner slices into thirds that are even because there would be an equal chance for each slice to be chosen. If I were to spin the spinner, I would have an equal 33.33% chance that it would land on $3, $5, or -$6. This makes it fair because they would all have an equal chance to be chosen!

HELPPP circle theorems
Serggg [28]

Answer:

56 degrees.

Step-by-step explanation:

We need the measure of < g.

The triangle formed by the 2 tangents and the chord is isosceles, because 2 tangents from a point  outside a circle are of equal length (by the Two Tangents theorem).

Also one of the base angles are equal to 62 degrees ( by The Tangent Chord theorem). In fact both base angles are 62 degrees because the triangles an isosceles.

So measure of angle g = 180 - 2(62)

= 56 degrees.
