Answer:
5 seconds
Step-by-step explanation:
Suppose the front parts of the trains meet at point A. Since both are the same length and traveling the same speed, each will pass point A in time ...
time = distance/speed
time = (1/18 mi)/(40 mi/h) = (1/720 h) × (3600 s)/(1 h) = 5 s
That is, the rear part of each train will be at point A 5 seconds after the front part.
The rear parts will pass each other 5 seconds after the front parts meet.

Answer:
I think that it is zy.
Step-by-step explanation:
I believe this because x angle is 100 degrees while y angle is 50 degrees. Z is still unknown, but since y is the smallest number of the 2 angles we do know, I think that it is safe to asume that zy is the shortest side.

Answer:
A polynomial is an algebraic expression made up of two or more terms subtracted, added, or multiplied. A polynomial can contain coefficients, variables, exponents, constants, and operators such as addition and subtraction.
It is also important to note that, a polynomial can’t have fractional or negative exponents. Examples of polynomials are; 3y2 + 2x + 5, x3 + 2 x 2 − 9 x – 4, 10 x 3 + 5 x + y, 4x2 – 5x + 7) etc. Like number, polynomials can undergo addition, subtraction, multiplication, and division.
We saw addition, subtraction, multiplication, and long division of polynomials previously.

Find the domain and range, and is it a function?
What is the Mean , Median , Mode , Range for
9,6,7,5,3
Answer:
the mean is 6
the median is 6
the mode there is none
the range is 6.
Answer:
There is no mode. (they all appear once)
The lowest number is 3 and the highest is 9, so the range is 6.
The mean is the average, add them all up (30) and divide by the number of data sets (5). The average is 6.
I have to go to dinner so maybe let someone else help with the median? The median is the middle, so you have to order them and find the middle. Hope it helped!

PLS HELP ILL GIVE BRAINLIEST XD
Answer:
No i think
Step-by-step explanation:
Its going by 3, im pretty sure u cant get to 220.
Answer: No
Step-by-step explanation:
1. The pattern is +3 because
-4+3=-1
-1+3=2
2+3=5
5+3=8
2. To see if 220 is in the sequence and the starting point is -4 instead of 0, subtract 220-(-4)=224. Since 224/3 is 74.6666666667, which is not an integer, then 220 does not appear in the sequence.

Nic sells advertising packages for a radio station. The company pays him $ 150 $150 per week and they also pay him $ 75 $75 for every package he sells. His friend Asia works for the same radio station but she receives a salary only, which is $ 1 , 275 $1,275 per week. How many packages does Nic need to sell in a week to earn as much as Asia?
Answer:
15 Packages
Step-by-step explanation:
Let number of packages = x
For Nic
Nic sells advertising packages for a radio station. The company pays him $ 150 per week and they also pay him $ 75 for every package he sells.
Equation =
150 + 75x
His friend Asia works for the same radio station but she receives a salary only, which is $ 1 , 275per week.
We solve by equating
150 + 75x = 1275
75x = 1275 - 150
75x = 1125
x = 1125/75
x = 15 Packages

Jennifer writes the letters M-O-N-T-A-N-A on cards and then places the cards in a hat. What is
the probability of picking an N?
Given:
Jennifer writes the letters M-O-N-T-A-N-A on cards.
To find:
The probability of picking an N.
Solution:
We have,
Total number of cards = 7
Total number of cards with letter N = 2
Now, the probability of picking an N is:
[tex]\text{Probability}=\dfrac{\text{Number of cards with letter N}}{\text{Total number of cards}}[/tex]
[tex]\text{Probability}=\dfrac{2}{7}[/tex]
Therefore, the probability of picking an N is [tex]\dfrac{2}{7}[/tex].
