Answer:
D is the answer
Step-by-step explanation:
We want a mixture of low-fat and whole milk to equal 32ounces
Therefore, we know one equation is:
l + w = 32
That 32 ounce mixture should be 2% butter fat
So the amount of butter fat we want is
2% of 32 = 0.64 ounces
At the same time, this mixture contains low-fat and whole milk, which contain 1% and 3.25% butter fat respectively.
therefore, the butter fat in low-fat and whole milk is 0.01l and 0.0325w respectively.
The coefficients are just the percentages in decimal form
Due to the law of conservation of mass,
The addition of these two should yield the final amount of butter fat, meaning the other equation is:
0.01l + 0.0325w = 0.64
Answer:
The answer I believe is 20
Step-by-step explanation:
Just add -34 + 54
She owes more than $30. She owes for the -$30 that we know of, however much over the -$30 she is, and most likely and interest fee as well.
Ratio given: 1:48
Ration to solve: ?:300
300 divided by 48 is 6.25, or 6 and 1/4.
Final answer: 6 minutes and 15 seconds
