As we know distance = rate*time
Aircraft carrier:
time is 13 hours, 7 hours before container ship left then the 6 hours container traveled.
Let s be speed of aircraft carrier
--> d = 13s
Container ship:
time is 6 hours
speed is 5 km/h slower, so s-5
--> d = 6(s-5)
Since they are going in opposite directions, add up the distances to find how far apart they are
--> 13s + 6(s-5) = 540
Now solve for s-
--> 13s +6s -30 = 540
--> 19s = 570
--> s = 30
Aircraft carrier was traveling at 30 km/h and container ship 25 km/h

Answer:
35, 100, 1.4
Step-by-step explanation:
Each value of 10 would equal 7. This would mean that 50 would equal 35 since 7x5=35. This would also mean that 100 would equal 70 since 7x10=70. This would also make sense for the last one since 10÷3=1.4

Answer:
y = 4x + 4
Step-by-step explanation:
The equations in the options are all in the slope-intercept form, y = mx + c. In this form, m is the slope while c is the y-intercept.
The slope of a line can be found using the formula below:
[tex]\boxed{\text{Slope}=\frac{y_1-y_2}{x_1-x_2} }[/tex]
In the formula, [tex](x_1, y_1)[/tex] is the first point and [tex](x_2, y_2)[/tex] is the second point on the graph.
Let's identify the two points in the graph which we can use to calculate the slope.
The 2 given points are: (-2 , -4) and (0 , 4)
Substituting the 2 pairs of coordinates into the slope formula:
Slope
[tex]=\displaystyle{\frac{-4-4}{-2-0}}[/tex]
[tex]\displaystyle{=\frac{-8}{-2}}[/tex]
= 4
Substitute the value of the slope into m:
y = 4x + c
The y-intercept, c, is the y value in which the line cuts through the y-axis (vertical axis). It is also the y-coordinate of the point when the x = 0.
In this question, we are given the point (0 , 4) which is also the y-intercept.
Substitute c = 4 into the equation:
y = 4x + 4
Thus, the equation shown in the graph is y = 4x + 4.

Answer: Using the mean concept, it is found that the average score of Adrian’s favorite team relative to its opponent using the observations Adrian made during the game is of -0.3333.
-----------------
The mean of a data-set is given by the sum of all observations divided by the number of observations.
Adrian looked the scores every 10 minutes in 2 hours, thus 12 times, as .
4 times ahead by 3 points, thus
4 times behind by 4 points, thus
At the other moments, the game was tied, thus the observation is 0.
The average score of Adrian’s favorite team relative to its opponent using the observations Adrian made during the game is of -0.3333.

Pamela rode her bike at a constant rate of 0.1 kilometer per minute. Which table represents y, the number of kilometers Pamela rode her bike in x minutes?
Answer:
Table B is correct
Step-by-step explanation:
Pamela is riding with constant speed of 0.1 km per 1 minute
so, by 5 minutes she would have travelled 0.5 km
since its constant speed so she will travel 0.1 km every minute and by 25 minutes she would have travelled 2.5 km

The population of Missoula, MT was 67,358 people in 2010. What was the increase if there were 75,516 people in 2019? What was the average increase per year?
Answer: 906
Step-by-step explanation:
75,516-67,358= 8,158
2019-2010= 9 years
8,158÷9= 906
The increase in the population is 8158 and average increase in the population per year is 906.4.
What is Subtraction?Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Given that,
Population of Missoula in 2010 = 67,358
Population of Missoula in 2019 = 75,516
Increase in the population = 75,516 - 67,358 = 8158
Average increase in the population per year = 8158 / (2019 - 2010)
= 8158 / 9
= 906.4
Hence the increase in the population is 8158 and average increase per year is 906.4.

What is the solution to this equation? 4x + 3 = 35
(PLS ANSWER ASAP)
Answer:
[tex]\boxed{\sf{x=8}}[/tex]
Step-by-step explanation:
It is necessary to isolate one side of this equation in order to find the solution.
4x+3=35
First, subtract by 3 from both sides.
[tex]\sf{4x+3-3=35-3}[/tex]
Solve.
Subtract.
35-3=32
[tex]\sf{4x=32}[/tex]
Then, divide by 4 from both sides.
[tex]\sf{\dfrac{4x}{4}=\dfrac{32}{4}}[/tex]
Solve.
Divide.
32/4=8
[tex]\Rightarrow \boxed{\sf{x=8}}[/tex]
Therefore, the solution is x=8, which is our answer.
I hope this helps, let me know if you have any questions.
Answer: x = 8
