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!

In a parallelogram WXYZ , W and X are adjacent interior angles the measure of X is three times the measure of W which equation g
Andrew [12]

Answer:

The required equation is \angle W+3\angle W=180^{\circ}.

Step-by-step explanation:

Given information: WXYZ is a parallelogram, W and X are adjacent interior angles and measure of X is three times the measure of W.

According to the properties of parallelogram, the two adjacent interior angle are supplementary angle and their sum is 180 degrees.

\angle W+\angle X=180^{\circ}            .... (1)

It is also given that the measure of X is three times the measure of W.

\angle X=3\angle W

Substitute this value in equation 1.

\angle W+3\angle W=180^{\circ}

4\angle W=180^{\circ}

\angle W=45^{\circ}

Substitute this value in equation 1.

\angle W=135^{\circ}

Therefore the required equation is \angle W+3\angle W=180^{\circ}.

5. Louis has 21 coins in his pouch, how many nickels and<br> dimes does he have if he has $1.35?
PolarNik [594]
N + d = 21
0.5n + 0.10d = 1.35
5n + 10d = 135
d = 21-n
5n + 210 - 10n = 135
-5n = -75
n = 15
d = 6
