A sector has radius 15 cm and area 113 cm? What is the measure, in radians, of the
central angle of the sector?

sup

step-by-step explanation:

b.

step-by-step explanation:

i just know

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x

the answer is a and d
