Answer:

It is B

Step-by-step explanation:

To solve this, you must use factoring:

You must find two numbers that multiply to -6, and add up to 5(y).

$y^{2} +5y-6=0$ turns into...

$(y+6)(y-1)=0$ because 6 × -1 = -6, and 6-1 = 5

after that, find the roots by solving for the x in each of the parentheses

so, $x=-6$ and $x=1$

2(2x-4) because when you multiply 2 x 2x it equals 4x. When you multiply 2 x 4 it equals 8. Leaving you with 4x-8

Last year Baron Enterprises had $800 million of sales, and it had $270 million of fixed assets that were used at 65% of capacity

Svetllana [295]

Answer: B. $430.80

Step-by-step explanation:

Given : Last year Baron Enterprises had $800 million of sales.

It had $270 million of fixed assets that were used at 65% (=0.65) of capacity last year.

Now, the used asset = $0.65\times270=\$175.5$ million

Now, Baron Enterprises had $800 million of sales in $175.5 million of assets , if we use all of $270 million of fixed assets , then the sales will be :-

$\dfrac{800}{175.5}\times270=1230.76923077\approx1230.80\text{ million}$

Now, the increase in Baron's sales before it is required to increase its fixed assets = $\$1230.80-$800=\$430.80\text{ millions}$

Hence, the increase in Baron's ( in million ) sales before it is required to increase its fixed assets = $430.80

A circle is drawn on the coordinate plane. It has a center at (2, 1) and passes through the point (2, 5). What is the approximat

ArbitrLikvidat [17]

First we need to find the radius. Using Pythagorean theorem we can find the radius which is the distance between the center and any point along the circle:

r=((5-1)^2+(2-2)^2)^(1/2)

r=(4^2-0^2)^(1/2)

r=4 units.

Circumference=2pr so our circumference is 8p units^2

Approximately 25.13 u^2
