Option A: y = 1/4x is the right answer
Step-by-step explanation:
The proportional relationship is defined as the increase/decrease in one quantity causes increase/decrease in other quantity.
The general form is:
y = kx
The proportional equations usually do not have any term that is added or subtracted.
comparing the given options with general form we can see that only one option is relatable to the general form of proportion.
Hence,
Option A: y = 1/4x is the right answer

Answer:
The length of pendulum is 55.853cm
Step-by-step explanation:
We are given
the original pendulum completed one swing every 1.5 seconds
so, T=1.5 sec
now, we can use time period formula
l is the length of pendulum
g is acceleration due to gravity
now, we can plug values
and then we can solve for l
In cm
Answer:
9 sleeves for 22.99
Step-by-step explanation
The first pack has a unit rate of $11.49/ 4 balls
=$2.8725
The second pack has a unit rate of $16.79/6balls
=$2.798 per ball
the third pack has a unit rate of $22.99/9balls
=2.554
So, I would definitely go for the third pack since it has the least cost.
Answer:
Step-by-step explanation:
P(A) = 0.70
P(B) = 0.20
P(A n B) = P(A) x P(B)
P(A n B) = 0.70 x 0.20
P(A n B) = 0.14
"Or" means that they are mutually exclusive, which it does not specifically mention, therefore B and C are out.
