Answer:

Try That

Step-by-step explanation:

5*2 1/4= 11.25

The amount of water lost and the number of days are proportional — the longer the leaking, the more water will be lost. If we increase the time “x” times, the amount of water will increase “x” times too. That said:

If the amount of time increased 5 times (1 day to 5 days) then the water will increase 5 times:

5 * 2.25 (or 2 1/4) = 11.25, or 11 1/4 inches of water is lost over 5 days.

What is the radius of a circle whose equation is x2 + y2 + 8x – 6y + 21 = 0?
s344n2d4d5 [400]

Answer:

2 units

Step-by-step explanation:

The given equation of the circle is:

x^{2} + y^{2}+8x-6y+21=0

The general equation of the circle is:

x^{2} + y^{2}+2gx+2fy+c=0

Comparing the given equation with the general equation we can say:

g = 4

f = -3

c = 21

The formula for radius of the circle is:

radius=\sqrt{g^{2} +f^{2} -c }

Using these values of the given circle, we get:

radius=\sqrt{(4)^{2}+(-3)^{2}-21}\\\\radius=\sqrt{4}\\\\radius=2

Therefore, the length of radius of the given circle is 2.

Anyone? Please I need help!!

Answer:

  the correct choice is marked

Step-by-step explanation:

Let x represent the smaller number. Then the larger number is 8x, and the difference is ...

  8x -x = 280

  7x = 280 . . . . . simplify

  x = 40 . . . . . . divide by 7

The larger number is 8x = 8(40) = 320.

_____

<em>Additional comment</em>

Effectively, we have solved for the multiplier (40) that gives the ratio with 320 on top and a difference between top and bottom of 280:

  \dfrac{8}{1}=\dfrac{8\cdot40}{1\cdot40}=\dfrac{320}{40}
