If the first increase was 50%, that means that the price between the first and the second increase is 150% of the original. And as you need 6 (which is 4*150%) times the original, the price was increased for 450%. So, the last peecent increase is
\frac{450}{150}  \times 100\% = 300\%

I NEED HELP PLEASE! :)
Andrej [43]

Answer:

Perpendicular

Step-by-step explanation:

To tell if the lines are perpendicular/parallel, you must look at the slope, but in this case, you must first get y by itself, like so:

3x + 7y = 15

-3x           - 3x

___________

7y = -3x + 15

<em><u>Divide both sides by 7:</u></em>

y = \frac{-3}{7}x + \frac{15}{7}

<em><u>Now the other equation:</u></em>

7x - 3y = 6

-7x         -7x

_________

-3y = -7x + 6

<em><u>Divide both sides by -3:</u></em>

y = \frac{7}{3} x - 2

You can see that the lines are perpendicular because the slopes (\frac{-3}{7} x and \frac{7}{3}) are opposite reciprocals.

The diameter of a planet is about 25,660 mi. The diameter of the planet's moon is about 35% of the diameter of the planet. What
kotegsom [21]

Answer:

4%

Step-by-step explanation:

Volume of sphere

v = (4/3)πr^3

Volume moon/ volume planet

We don't actually need the numeric value of the radius

just the 35% ratio

Radius of moon = .35 radius of planet

Vm/ Vp = (4/3)π(.35r)^3 / (4/3)π(r)^3

Cancel like terms

Vm / Vp = .35^3

Vm / Vp = 0.042875

Expressed as a percentage

Vm / Vp = 4.2875%

Rounded

Vm / Vp = 4%
