For sales tax, you just have to multiply the percentage by the number. So you can only have one step, add 1 after you divide the percentage by 100.
45.5•1.07=48.685
The cent only goes to the hundredths, so we have to round.
The total amount is $48.69.
Number line usually helps a lot
Start at the first number and move to the left for subtracting and to the right for adding. Hope this helps.
Answer:
120 minutes
Step-by-step explanation:
1/4=0.25
96x 0.25= 24
96+24=120 minutes
Answer:
I'm pretty sure n represents 96, because 26×4=96
Use the trig ratio which
gives you the most information. Here we have opposite and hypotenuse
relative to angle x, so think sin( x ) = 14.1 / 27.9<span>Now we want to solve for x, but x is stuck inside the sine function
So how do we do this?
We can 'undo' the sine function by using the inverse sine. apply the inverse Sin to both sides of the equation.
sin^-1 ( sin(x) ) = sin^-1 ( 14.1 / 27.9)
the left side 'cancels' , leaving you with x
x = sin^-1 ( 14.1 / 27.9)</span><span>Now you need a calculator.
Make sure you are in degree mode.
Calculators can give you answer in radian or degree.
If you get a decimal answer, you are probably in radian mode.
Round up if you want nearest hundredth
30.3563 ≈ 30.36
Round up again if you want nearest tenth
30.36 ≈ 30.4
Hope this helps! :)
