Answer:
- 15 mL of 100% vinegar
- 45 mL of Italian dressing
Step-by-step explanation:
Let v represent the amount of 100% vinegar to be included in the mixture. Then the amount of vinegar in the overall mixture is ...
1.00v + 0.08(60 -v) = 0.31(60)
0.92v = 60(0.23) . . . . . . . collect terms, subtract .08(60)
v = 60(0.23/0.92) = 15 . . . mL of vinegar
60 -v = 45 . . . mL of dressing
15 mL of vinegar and 45 mL of Italian dressing should be used.

Answer: True
Step-by-step explanation:
The statement that a mixed number has a whole number part and a fractional part is true.
The mixed number is made up of a whole number, and a proper fraction. A mixed number simply means a number that is between any two whole numbers. Examples of mixed numbers are 4¾, 7½ etc.
(1.2×10^2) + (3.04×10^5)
They must be to the same power to add
3.04 *10^5 to change to the 2nd power (5-2=3) move the decimal 3 places to the right = 3040. * 10^2
1.2 * 10^2 + 3040 *10^2=
add the numbers keep the exponents the same
3041.2 * 10^2
there can only be 1 number before the decimal in scientific notation so we need to move the decimal 3 places to the left, which adds 3 to the exponent
3.0412 * 10 ^ (2+3)
3.0412 * 10^5
