Sophia walked 6 miles in 90 minutes at bear creek park in eluless, texas. if she continued at this rate , use a ratio table to determine how many miles she could walk in 60 minutes.

4 miles

Step-by-step explanation:

the data we have is:

  Miles     Minutes

     6      ⇒  90

and the thing we want to know is how many miles she could walk in 60 minutes:

  Miles     Minutes

     6      ⇒  90

     x      ⇒  60

where the x represents the unknown number of miles she will walk in 60 minutes.

we solve this problem using rule of three, for this we multiply cross quantities (6 by 60) and then we must divide by 90:

x = 6*60/90

x = 360/90

x = 4

in 60 minutes she walks 4 miles.

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
