Answer:
10
Step-by-step explanation:
The perimeter will also be halved: (1/2)(20) = 10.
Example: a rectangle of length 14 ft and width 8 ft has perimeter P = 2(14 ft) + 2(8 ft), or 28 ft + 16 ft = 44 ft.
If we halve the length and width, we get 7 ft and 4 ft, and the P is
2(7 ft) + 2(4 ft) = 14 ft + 8 ft = 22 ft, which is half of the original perimeter 44.
Answer:
linear
Step-by-step explanation:
linear means that is gains and loses in a straight line. if you were to graph the points on a chart the line will be straight
you can see in set 1 there is one ball
1:1
set 2 is 2 balls
2:2
and set 3 is 3 balls
it increases at a steady rate
therefore it is linear
YESSSS IT ISSSS CORRECTTT!!!!❤️❤️
The volume of a sphere is found with
V=(4/3)π(r³)
V=(4/3)π(1.9³)
V=(4/3)π(6.859)
V=(9.1453...)π
V=28.716
V≈28.71
The surface area is found with
A=4π(r²)
A=4π(1.9²)
A=π(3.61)
A=11.335
A≈11.34
The ratio of volume to surface area is 28.71 : 11.34.
If you round the numbers to 28.70 and 11.35, then the ratio will be 2:1.
