Answer:

Step-by-step explanation:

using the pythagorian theorem, we know that a^2+b^2=c^2. inputting the numbers into this equation, we get

8^2+23^2=c^2

then, using our big math brains, we get 64+529=c^2

adding together the numbers, we end up with 593

just take the sqyare root of that and bada bing bada boom! you get 24.35, or 24.4, therefore the answer is C

What is the simplest form of (3x^1/2)(4x^2/3)

ValentinkaMS [17]

When multiplying, we add exponents.

So first get a common denominator of 6.

3/6 + 4/6 = 7/6

So the answer is 12x^(7/6)

Please answer this correctly without making mistakes

Answer:

263.76

Step-by-step explanation:

Assuming the shaded area is the yellow area all we must do is find the area of the small circle and subtract it from the larger circle.

To do this we can use the area of a circle equation:

$A=\pi r^2$

first we need to find the radius of the large circle which is simply 4+6= 10

so the area would be:

$A=\pi 10^2\\A=100\pi$

then we find the area of the small circle is

$A=4^2\pi \\A=16 pi$

next we evaluate:

$100\pi -16\pi =84\pi$

Then replace pi with 3.14:

84 · 3.14 = 263.76

And you have your answer!

Hope this helps!
