Answer:
I think the answer is c if i am not mistaken
Step-by-step explanation:
Answer:
Amount of vinegar. 100% : 20 milliliters
Amount of Italian dressing: 140 milliliters
Step-by-step explanation:
Let's call A the amount of vinegar. 100%
Let's call B the amount of Italian dressing . 12% vinegar
The resulting mixture should have 23% vinegar, and 160 milliliters.
Then we know that the total amount of mixture will be:
Then the total amount of pure antifreeze in the mixture will be:
Then we have two equations and two unknowns so we solve the system of equations. Multiply the first equation by -1 and add it to the second equation: We substitute the value of B into one of the two equations and solve for A.
Answer:
11/21
Step-by-step explanation:
V = 4/3
V = 4/3(22/7)
V = 4/3(22/7)(1/8) = 88/168 or 11/21
It's kind of confusing because of the exponents and fractions but basically the first line if the equation for finding the volume of a sphere. The second is replacing the variables like pie and radius to the given numbers. The last line is all the factions multiplied.
