42=(2w-6)+(2w-6)+w+w
42=6w-12
54=6w
w=9
42=2l+18
24=2l
l=12
length= 12cm, width= 9cm
Answer:
y = 1/3x - 3
Step-by-step explanation:
If the line is perpendicular to y = -3x + 11, it means that the two gradients multiply to make -1.
So the gradient of the perpendicular line is 1/3 (-3 × 1/3 = -1)
y = 1/3x + c
Next, substitute x = -9, and y = -6 to find the y intercept, or c:
-6 = 1/3(-9) + c
-6 = -3 + c
c = -6 + 3
c = -3
The equation of the line is y = 1/3x - 3
Answer:
The size of the angle is between 180 and 360*. I cannot say the exact angle but my guess is correct and the correct answer is in between the 2 numbers.
Step-by-step explanation:
Answer: 3 inches wide (estimated orignially it came up to 2.65)
2 inches length
Step-by-step explanation:
Answer:
6 or 3mL/hr, probably 3mL/hr
Step-by-step explanation:
If dopamine makes up half of the solution then you half the total mL/hr to 3. If it is the whole solution then it tells you the answer (6mL/hr). I'm not sure if the question is poorly worded or just how you typed it but it would be easier to answer if it was clearer.
