first you combine like term

3x+12x=2

15x=2

then you divide 15x by 2

x=7.5

I hope that's the answer

Andy has a snowball (a perfect sphere) with the radius of 3 cm. He wanted the snowball to be bigger, so he spent four seconds pa

BigorU [14]

Answer:

Ratio = $\frac{64}{27}$

Step-by-step explanation:

Volume of Sphere is given by the formula:

$V=\frac{4}{3} \pi r^3$

Where

V is the volume

and

r is the radius

Original Volume, given r = 3, would be:

$V=\frac{4}{3} \pi r^3\\V=\frac{4}{3} \pi (3)^3\\V=\frac{4}{3}\pi (27)\\V=36\pi$

Increased snowball volume:

Radius increased 0.25 per second, he spent 4 seconds, so radius increase:

0.25 * 4 = 1 cm

New radius = 3 + 1 = 4 cm

New Volume would be:

$V=\frac{4}{3} \pi r^3\\V=\frac{4}{3} \pi (4)^3\\V=\frac{4}{3}\pi(64)\\V=\frac{256\pi}{3}$

Ratio of New Volume to Original would be:

$Ratio=\frac{\frac{256\pi}{3}}{36\pi}=\frac{256\pi}{3}*\frac{1}{36\pi}=\frac{64}{27}$

This is the ratio for current volume to original volume.

Brandon is thinking of a number that is divisible by 6 and 8 . What is the smallest number that Brandon could think of

a_sh-v [17]

since

6 = 2 * 3 <--- two factors

8 = 2 * 2 * 2 <--- three factors

and since the "2" is there on each, then we can just use that instance of it once.

so instead of using 2 * 3 * 2 * 2 * 2, we'll use 2 * 3 * 2 * 2, and that is our LCD.

2 * 3 * 2 * 2 = 24.

If $x$ and $y$ are positive real numbers for which $(x + y)^2 + (x - y)^2 = 10$ and $(x + y)^4 + (x - y)^4 = 98$, what is the va

slava [35]

$(x+y)^2+(x-y)^2=10$
$\implies 2x^2+2y^2=10$
$\implies x^2+y^2=5$
$\implies (x^2+y^2)^2=x^4+2x^2y^2+y^4=25$

$(x+y)^4+(x-y)^4=98$
$\implies 2x^4+12x^2y^2+2y^4=98$
$\implies x^4+6x^2y^2+y^4=49$
$\implies 25+4x^2y^2=49$

$4x^2y^2=24$
$\implies x^2y^2=6$
$\implies xy=\sqrt6$
