Perimeter is adding all 4 sides together.
To find the length and width divide total perimeter by 2:
21 / 2 = 10.5
We now know the length of 1 side and the width of 1 side need to equal 10.5.
Since the original piece was a square we also know the width needs to equal 1/2 of the length.
So we have L + 1/2L = 10.5
Add the common terms 1 L + 1/2 L = 1 and 1/2 L
To Find L divide 10.5 by 1-1/2, which equals 7
To find the width subtract 7 from 10.5, which equals 3.5
So the paper is now 3.5 inches by 7 inches.
Answer:
x=21°
Step-by-step explanation:
64°=3x+1 --------- because vertically opposite angles are equal
63=3x
x= 63/3
x=21°
As likely as not. There are 26 red cards and 26 black cards, so there is a 50% chance of getting red and a 50% chance of getting black.
Answer:
Step-by-step explanation:
Tn = ar^(n-1)
a = 4, r = 8/4 = 2 for n = 15
T15 = 4 × 2^(15-1)
= 4 × 2^14
= 4 × 16384
= 65536
