Answer:
−8.85174904 The first answer
Step-by-step explanation:
It is 52 that’s the answer
you would have to do 170/20 which equals 8.5 multiply that by 8
so his daily does would be 510 milligrams
In order to find the area of the semicircle, or the shaded region, we just have to find the area of the entire circle and divide it by 2. The formula for the area of a circle is

. With the given diameter of 12, we can deduce that the radius is 6.
Area of Semicircle = (

/2)
Area of Semicircle = (3.14 x 36/2)
Area of Semicircle = (3.14 x 18)
Area of Semicircle = 56.52

Hope this helps!
We are told to solve for n given the equation 3(n + 4) = -6 + 15n. We can solve for n by first using the distributive property, which gives us 3n + 12 = -6 + 15n. Now, subtract 15n from both sides, giving us -12n + 12 = -6. Next, subtract 12 from both sides to get -12n = -18. Now, divide both sides by -12 to get n = 18/12, or 3/2 when simplified. Therefore, the value of n in the equation 3(n + 4) = -6 + 15n is 3/2. Hope this helped!
