The price of a silk scarf is $32. the sales tax is $1.92. what is the sales-tax rate?

sales-tax rate = 6%

Step-by-step explanation:

The price of a silk scarf is $32. The sales tax is $1.92

Let the sale tax rate be s%

Price of silk scarf = $32

Sale tax = s% of 32

Sale tax = $1.92

Thus,

s% of 32 = 1.92

First we change s% to decimal

Hence, The sales-tax rate is 6%

step-by-step explanation:

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
