Answer:
10.9
Step-by-step explanation:
Pythagoras theorem- a² + b² = c²
Since this is a right angle with each side on the right angle's length given you can use pythagoras theorem.
7² + 8.44² = c²
= 49 + 70.56 = c²
= 119.56 = c²
∴ c = √119.56
= 10.9
45.00
45/15
30.00

Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
In this case:
m = -6
b = 8
This means that -6 is the slope and (0, 8) is the y-intercept.

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:

Let's take 丌 as 3.14
The volume of the balloon with 4cm radius:

The volume of the balloon with 8cm radius:

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!
