This is a chemistry problem btw. But, either way, the formula for density is mass per unit of volume. To solve for volume, bring the D over to get M/D = V
(327g)/(1.05g/ml) is the equation. Grams cancel and you’re stuck with 311.428571mL. That isn’t your answer tho, because that isn’t the right amount of sig figs. We have two figs at the least so the right answer would be 311.42 or 311.43mL. We want it in scientific notation, so move the decimal place between 3 and 1. That’s two spots to the left, so the power would be 2. C is your right answer
My chem professor told me to round to even instead of rounding up all the time. Either way, the hundreds place is always a percent error of plus or minus 0.01
Answer:
A = 3; B = -2; C = 2
Step-by-step explanation:
Original line:
3x - 2y = 1
Slope of original line:
-2y = -3x + 1
y = 3/2 x - 1/2
slope = m = 3/2
Parallel lines have equal slopes, so we need the equation of the line with slope 3/2 that passes through the point (-6, -10)
y = mx + b
y = (3/2)x + b
Substitute -6 for x and -10 for y and solve for b.
-10 = (3/2)(-6) + b
-10 + 9 = b
b = -1
Equation: y = (3/2)x - 1
2y = 3x - 2
3x - 2y = 2

Answer:
The tax is $0.12
Step-by-step explanation:
If you can imagine that price of $3 to be 100% of the price, you can simply add 4.4 onto this to find the percentage you need to find of the price:
100 + 4.4 = 104.4
So now you can use the percentage formula:
Amount x 
Simply plug all the values into this:
3 x 
3 x 1.04 = 3.12
Now you have the total price and you can simply minus the item cost without tax:
3.12 - 3 = 0.12
<h3>So the tax is $0.12!</h3><h3 /><h2>Hope this helps!</h2>
The third choice , i mean you always have to go with c
