Find the sales tax for 3 CD's, if each CD is $14.29 and the sales tax is 7.25%

Answer:

The radius of the can, rounded to the nearest hundredth, is 530.66.

Step-by-step explanation:

We want to do the reverse of the formula for V, which is pi(r)^2(h).

to isolate r.

Let's start by writing an equivalent equation to V = h by solving for r

Now, substitute and solve for r

1014 * 3.14 / 6 = 530.66

Answer: 1 = 69°, 2 = 69°, 3 = 111°

Step-by-step explanation:

The image is that of an isosceles trapezoid.  Which means:

1. The base angles (1 & 2) are congruent (equal)
2. which results in the other set of base angles (3 and 111°) being congruent.  
3. Since it is a quadrilateral (4 sides), the sum of the angles is 360°

∠3 = 111°   →  refer to #2 above.

Let ∠1 =x, then ∠2 = x  → refer to #1 above

2(111) + 2(x) = 360    →    refer to #3 above

222 + 2x = 360

          2x = 138

            x = 69

Answer:

b) Is associated with motor impairment but does not cause it

Step-by-step explanation:

The study didn't explain the timeline of their findings, so we can conclude this research takes data at one time. Research that doesn't take before and after exposure data cannot be used to derive causation since we can't prove that the condition happens after the exposure. But this study still can predict association by risk ratio or odds ratio depends on the study design.

Answer:  I used the answer b) Is associated with motor impairment but does not cause it ... on the Plato test and got the answer wrong.  Choose a different answer.
