The area is:

A = πR² ------- 2π

A = x --------- π/6

x = πR²/12

x = π.(10)²/12

x =  26.18 in²

Hope it helps x

Answer:

Circumference ≈ 82.9

Step-by-step explanation:

The formula for calculating the circumference of a circle is:

C = 2πr

Where 3.14 is pi (as stated on your screen)

And r is the radius.

Knowing this substitute those values

C = 2(3.14)(13.2)

Multiply 2 and 3.14.

C = (6.28)(13.2)

Multiply 6.28 and 13.2.

C = 82.9 when rounded.

Find the limit, if it exists, or type dne if it does not exist.
Phantasy [73]
\displaystyle\lim_{(x,y)\to(0,0)}\frac{\left(x+23y)^2}{x^2+529y^2}

Suppose we choose a path along the x-axis, so that y=0:

\displaystyle\lim_{x\to0}\frac{x^2}{x^2}=\lim_{x\to0}1=1

On the other hand, let's consider an arbitrary line through the origin, y=kx:

\displaystyle\lim_{x\to0}\frac{(x+23kx)^2}{x^2+529(kx)^2}=\lim_{x\to0}\frac{(23k+1)^2x^2}{(529k^2+1)x^2}=\lim_{x\to0}\frac{(23k+1)^2}{529k^2+1}=\dfrac{(23k+1)^2}{529k^2+1}

The value of the limit then depends on k, which means the limit is not the same across all possible paths toward the origin, and so the limit does not exist.

A 3mL unit dose of levalbuterol HCl contains 0.63mg of active ingredient. If 2 unit doses are used, how many mg of active ingred
Sergio039 [100]

Answer:  0.42 mg

Step-by-step explanation:

Given : A 3mL unit dose of levalbuterol HCl contains 0.63mg of active ingredient.

Then , the amount of active ingredient in 1 ml dose of levalbuterol HCl = \dfrac{0.63}{3}

=\dfrac{63}{300}=\dfrac{21}{100}=0.21\ mg

Hence, the amount of active ingredient in 2 ml dose of levalbuterol HCl will be :-

2\times0.21=0.42\ mg

Hence, the amount of active ingredient in 2 ml dose of levalbuterol HCl =0.42 mg

A bookstore had 64 copies of a magazine. Yesterday, it sold 1/4 of them. Today, it sold 1/8 of what remained. How many copies do
just olya [345]

Answer: 42

yesterday it was sold 1/4 , so it was sold 64/4=16

today it was sold 1/8 from what remained, which is 6(see below)

64-16=48

48/8=6

the store has left 48-6=42
