6 because 4 tripled is 12 . And subtract 2 each day . It will take six days until you get zero
16
it would be 16 cause 7.2+9.6= 15.8
This is the same as the last question you asked. 63 + 61 = 124. 180 - 124 = 56. Angle ACB is 56 degrees.
Answer:
Part a) 2.36 quarts
Part b) 47.2%
Step-by-step explanation:
Let
x ---> percentage of the resulting mixture that is antifreeze
Remember that
we know that
3 quarts of a solution multiplied by 0.22 (percentage in decimal form) plus 2 quarts of a solution multiplied by 0.85 (percentage in decimal form), must be equal to 5 quarts of a solution multiplied by x (percentage of the resulting mixture)
so
The linear equation that represent this situation is
solve for x
Convert to percentage
therefore
The percentage of the resulting mixture that is antifreeze is 47.2%
To find out how many quarts of antifreeze are in the resulting mixture, multiply the total quarts of the resulting mixture by the percentage in decimal form
