Last autumn, julia noticed something interesting as she blew up spherical balloons for harris's birthday party. she calculated t
Vikki [24]
To find whether the volume would be doubled when the radius is,we can find the volume of the two balloons.

The formula of a sphere is:
\frac{4}{3} \pi \: {r}^{3}
Let's take 丌 as 3.14

The volume of the balloon with 4cm radius:
\frac{4}{3}(3.14)  \times  {4}^{3}  \\  = 4.18667 \times 64 \\  = 267.94688

The volume of the balloon with 8cm radius:
\frac{4}{3}(3.14)  \times  {8}^{3}  \\  = 4.18667 \times 512 \\  = 2143.57504
As we can see,
267.94668 × 2 = 535.89 ≠2145.56

Thus,she wouldn't discover that the volume is twice as big when the radius is doubled.

Hope it helps!

Solve the equation 14y+82=6x-20 for x if y is 25
Leni [432]

Answer:

x= 226/3 or 75.33333333333333333333333333333

Step-by-step explanation:

14y+82=6x-20

y=25

Sub y=25 into 14y+82=6x-20

14y+82=6x-20

14(25)+82=6x-20

Calculate as follows:

14(25)+82=6x-20

350+82=6x-20

432=6x-20

Add twenty to both sides:

432+20=6x-20+20

452=6x-0

452=6x

Divide both sides by 6

452=6x

452/6=6x/6

452/6=x

x= 226/3 or 75.33333333333333333333333333333
