A stand was selling 8 mangos for $10 at a farmers' market. Keisha said, "That means we can write the ratio 10:8, or $1.25 per mango."
Luis said, "I thought we had to write the ratio the other way, 8:10, or 0.8 mangos per dollar."
Who is correct, and why? Can we write more than one ratio for this situation? Explain why or why

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

yes ok                                            

answer is 270 degrees: -

to convert radians to degrees you multiply by 180/π

9π/ 6 * 180 / π

=   9 * 180 / 6

= 9 * 30

=   270 degrees   answer

answer: the up tack or falsum is a constant symbol used to represent a logical constant denoting "false" in logic.
