False because it will only last 2.4 hours. 12 x 20% = 2.4. Hope I could help! :)

Does anyone know how to simplify? 5y(2y-3) + (2y-3) = ?

mamaluj [8]

Hey there!!

The given equation :

... 5y ( 2y - 3 ) + ( 2y - 3 )

Let's write this as ...

... 5y ( 2y - 3 ) + 1 ( 2y - 3 )

Now, if we take ( 2y - 3 ) as a common term, we get...

... ( 5y + 1 ) ( 2y - 3 )

Hence, the correct answer would be option ( A )

Hope my answer helps!!

A region is bounded by semicircular arcs constructed on the side of a square whose sides measure 2/\pi, as shown. What is the pe

Paladinen [302]

Answer:

4

Step-by-step explanation:

The perimeter of the region is equal to the sum of the perimeter of the four semicircular arc. Since the semicircular arcs have the same measure, therefore:

Perimeter of region = 4 × Perimeter of semicircular arc.

The side of the square = diameter of the semicircle = 2/π.

The radius of semicircle = diameter/2 = $\frac{2/\pi}{2} =\frac{1}{\pi}$

The perimeter of a semicircle = perimeter of a circle ÷ 2

$Perimeter\ of \ semicircle = \frac{perimeter\ of\ circle}{2}=\frac{2\pi r}{2}=\frac{2\pi (\frac{1}{\pi} )}{2} =1\\ Perimeter\ of\ region = 4*Perimeter\ of \ semicircle=4*1=4\$
