Answer:
4.
Step-by-step explanation:
First, you have to decide whether the slope is negative or positive. Since the line is going diagonally upward, it is positive.
That means the answer has to be either 3 or 4.
Next, you have to decide whether the y-intercept is negative or positive, on the graph, you can see that it is positive.
Answer choice 4 is the only equation where both the slope and the y-intercept are positive, so it is the answer.
8/11 is the fraction
To derive this simply put
72.727272/100 and it reduces to 8/11
Answer:

Step-by-step explanation:
Answer:
176 of 12% vinegar
44 of 7% vinegar
Step-by-step explanation:
Percentage vinegar required = 11%
Volume = 220 mL
First brand % = 7%
Second brand % = 12%
Let p = volume of 12% vinegar material
Mixture :
0.12p + 0.07(220 - p) = 220 * 0.11
0.12p + 15.4 - 0.07p = 24.2
0.05p = 8.8
p = 8.8 / 0.05
p = 176
176 of 12% vinegar and
220 - 176 = 44
44 of 7% vinegar
Answer:
27 hours
Step-by-step explanation:
Let her work "x" hours for paperwork
Since, patrolling amount of hours is THREE TIMES that,
Patrolling = 3x hours
Total Hours = 36
That is including paperhour work (x) and patrolling (3x). So we can setup an equation in x and solve for x first:
x + 3x = 36
4x = 36
x = 36/4
x = 9 hours
Amount of Hours for Patarolling = 3x hours = 3(9) = 27 hours
So, she spends 27 hours patrolling
