Drinking 8 fluid ounces of milk provides 270.0 milligrams of calcium. how many fluid ounces of milk provide 72.5 milligrams of calcium? round to the nearest tenth. a. 2.1 fluid ouncesb. 2.3 fluid ouncesc. 2.6 fluid ouncesd. 1.8 fluid ounces

A. 2.1 fluid ounces

Step-by-step explanation:

Following information given in the statement

8 ounce milk=270.0 mg calcium

we have to find how many ounce of milk=72.5 mg calcium

Let x be the amount of milk possess 72.5 milligrams of calcium.

So, x=(72.5*8)/270

x=580/270=2.148

Rounding x to nearest tenth

x=2.1

Hence, 2.1 ounce milk contains 72.5 mg calcium.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
