Hmmm... try adding the sides and dividing by the number of sides on the shape
Answer:
A
Step-by-step explanation:
A]
7*5 = 35+15 = 50
10*70 = 70 +14 = 85
15*7 = 105 +15 = 120
20*7 = 140+15 = 155
B]8.50*5 = 42.5
C]10*5 = 50
10*10 = 100
D] = 8*5 = 40 +10 = 50
10*8 = 80+10 = 90
Xd = y(L-d) then divide by "y"
xd/y = L - d then add "d"
xd/y + d = L
Answer:
a3 = 45
Step-by-step explanation:
a1 = 20
an = a(n-1) *3/2 where n is the term number
a2 = a(2-1) *3/2
a1 *3/2
We know a1 = 20
a2 = 20*3/2 = 30
a3 = a(3-1) *3/2
= a2 *3/2
We know a2 = 30
= 30*3/2 = 45
Answer:
6/12 or 1/2 or 50% or 0.5
Step-by-step explanation:
You have two 6-sided dice, and there are 3 odd numbers on each.
So, you put 6 on top, (the total number of odd outcomes) and 12 on the bottom. (12 total outcomes for both dice.) This simplifies to 1/2 or 50% or .5.
