The fourth child inherited 3/10 of the estate.
2/10+2/10+3/10= 7/10, so you need 3/10 to complete the equation.
Considering the surface area of the spherical ballon, it will take 7 seconds for the the balloon to fully inflate.
<h3>What is the surface area of a sphere?</h3>
The surface area of a sphere of radius r is given by:

In this problem, the surface area is of
cm², hence the radius in cm is found as follows:





r = 14 cm.
The radius start at 0 cm, inflating at a rate of 2 cm/s, hence it will take 7 seconds for the the balloon to fully inflate, as 14 cm/(2 cm/s) = 7 s.

Step-by-step explanation:
if the digit in the tenth place is less then 5, then round down, which means the units digit remains the same. If the digit in the tenth place is 5 or greater then round up which means you should increase the unit digit by one.
2^9=512

Step-by-step explanation:
Possible equations with x as 3:
2x=6
3x=9
4x=12
5x=15
10x=30
10+2x=16
4x+32=44
23-5x= 8
42÷2x=7
2x × 2=12
These are just a few possibilities with x as 3.
