Answer:
She is going at the rate of 4.5 feet per second.
Step-by-step explanation:
Given:
The rate of walking is 90 yards per minute.
Now, to find the rate in feet per second.
1 yard = 3 foot.
1 minute = 60 seconds.
So, first we find the rate of walking per second in yard = 
Therefore by dividing we get = 
Now, we find the rate of walking per second in feet = 
So, by multiplying we get = 
Therefore, she is going at the rate of 4.5 feet per second.

Answer:
15/121.
Step-by-step explanation:
Probability of picking a red = number of reds in the bag / total number of marbles in the bag
= 3 / (3 + 3 + 5)
= 3/11.
Probability of picking a blue = 5/11.
These 2 events are independent so we multiply probabilities, therefore the
Probability of (a red then a blue) = 3/11 * 5 /11
= 15/121.
Answer: 12
Step-by-step explanation:
A polynomial is an expression that contains more than one number, letter, etc. so 12 is a monomial, because it only has one number. Hope this helps!!
