A city has a sales tax rate of 9%. If Dion paid $6.30 in sales tax on a new guitar pedal, how much was the purchase price of the pedal? amount of change = 6.3
3.6
9.0

b.an increase in a causes b to decrease

i think it is 70

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
