He added that the agency is currently not studying the chemical in coffee. The Federal limit on residues of the chemical in the coffee is 10 parts per million, but generally, coffees decaffeinated with it have less than half that amount.
Answer:
502.4 square inches
Step-by-step explanation:
To find the area of the shaded region, you first need to find the area of the smaller circle with diameter 12, and then subtract that from the area of the larger circle. Since the diameter of a circle is twice the radius, the radius of the smaller circle is 6, and its area is therefore:
![\pi \cdot 6^2 = 3.14\cdot 36=113.04](https://tex.z-dn.net/?f=%5Cpi%20%5Ccdot%206%5E2%20%3D%203.14%5Ccdot%2036%3D113.04)
The area of the larger circle, which has radius 6+8=14, is:
![\pi \cdot 14^2= 3.14 \cdot 196=615.44](https://tex.z-dn.net/?f=%5Cpi%20%5Ccdot%2014%5E2%3D%203.14%20%5Ccdot%20196%3D615.44)
Subtracting the area of the smaller circle from his, you get an area of 502.4 square inches for the shaded area. Hope this helps!
Let's simplify step-by-step.
x−5x+4+8x−71
=x+−5x+4+8x+−71
Combine Like Terms:
=x+−5x+4+8x+−71
=(x+−5x+8x)+(4+−71)
=4x+−67
Answer:
=4x−67
Answer:
This is a Retrospective study
Step-by-step explanation:
Retrospective study is a study that compares two groups of people; those with disease or condition under study and a very similar group of people who do not have the disease or condition.
Here they are compring those men with high blood pressure who drank and those with no high blood pressure and don't drink.
The correct answer is 12/20.
If you multiply the numerator and the denominator of 3/5 by 4/4:
3•4 = 12
————-
5•4 = 20
Therefore, the equivalent of 3/5 is 12/20.
