It’s hard to answer this without more information. Which author?¿ Because each author has their own ways.
Tax= sales price x tax percent
Tax= $40 x 6.5%
Convert % decimal to decimal: 6.5% by 100
Tax= 40 x 0.065
Tax= $2.60
Answer: sales tax is $2.60
Hope this helps!
We don’t know what was taught in the lesson, so we’re just guessing what your book/teacher said. However, the most common tire rotations are usually B or C.

This might sound weird and I know it's not the answer and I'm sorry, but what does SAT stand for???
Explanation:
The mass of the acetic acid is 1.512 g.
<h3 /><h3>What is Molarity?</h3>
molarity is the concentration of a substance in mol per dm³
From the question,
The number of moles contained in the 30 mL vinegar is
- n = (0.84×30)/1000
- n = 0.0252 mol.
the molar mass of vinegar is calculated below.
- m.m of (HC₂H₃O₂) = [1+(12×2)+(1×3)+(16×2)]
- m.m = (1+24+3+32]
- m.m = 60 g/mol.
To calculate the mass of acetic acid, we use the formula below.
- R.m = n×m.m............. Equation 1
Where
- R.m = mass of acetic acid.
Substitute these values into equation 1
- R.m = (0.0252×60)
- R.m = 1.512 g.
Hence, The mass of the acetic acid is 1.512 g.
