ok so lets say that you have a pizza cutted out in 5 sections and want to pick up only a certain piece, let's say pepperoni. If you took a piece at random, the chances of getting that certain piece of pepperoni in 60 spins is: 12 / 60
Answer:
<u>The number of intersections = ∞</u>
Step-by-step explanation:
Given the system of equations:
0.5 x + 5y = 6
3x + 30y = 36
By multiplying the first equation by 6
∴ 6 (0.5 x + 5y) = 6 * 6
∴ 3x + 30y = 36
So, Those equations are "Dependent", because they are really the same equation, just multiplied the first equation by 6.
So, the two equations are identical
Therefore: <u>They have infinity number of solutions.</u>
<u>See the attached figure.</u>
0.5 x + 5y = 6 ⇒ in black color
3x + 30y = 36 ⇒ in red color
When using graphs to find proportional and nonproportional is easy. When it's proportional it goes right through the origin and it's nonproportional it doesn't go through the origin.
Answer:
I think it is A, I might be wrong.
Step-by-step explanation:
Answer:
JK = 13
Step-by-step explanation:
Note that corresponding sides are congruent.
Thus ST = KL and JK = RS
Given ST = 16RS and KL = 13JK + 39, thus
KL = 13JK + 39 ( KL = ST = 16RS ), substituting
16RS = 13RS + 39 ( JK = RS )
Subtract 13RS from both sides
3RS = 39 ( divide both sides by 3 )
RS = 13
However, RS and JK are corresponding sides and congruent, thus
JK = RS = 13
