Answer:
1/7.
Step-by-step explanation:
You can find which is closest to zero by using the LCD. However, the question itself just shows us that 1/7 is the right choice. If you want the work, just comment.
We're given
which immediately tells us that
In other words, swapping the limits of the integral negates its value.
Also,
The integral we want to compute is
which we can do by splitting up the integral at x = 4 and using the known values above. Then the integral we want is
Answer: -2/3
Step-by-step explanation:
The slope intercept form of that equation is y=(3/2)x+4, so the slope is 3/2.
To find the perpendicular slope, you need to find the opposite reciprocal. The reciprocal of 3/2 is 2/3, the opposite of 2/3 is -2/3
Answer: He made 110 kilograms of 9.09% salt solution.
Step-by-step explanation:
Given: Mass of water= 100 kg
Mass of salt= 10 kg
Total mass of the solution: 100kg+10kg= 110 kg
The percent of salt in solution=
∴The percent of salt in solution
Therefore, He made 110 kilograms of 9.09% salt solution.
They sell tacos for $3.25 each which would be $3.25x....and they make an expense of $210 a day so your equation would be... $3.25x = $210 in which you would divide 210 by 3.25 to get your answer on how many tacos they would have to sell per day to make that expense....
