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?
Answers
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.

Answers
Answer: $10
Step-by-step explanation:Let the money spent by each friend = $x
Number of persons including Donovan = 4
Total amount spent by all friends all together = $4x
Since each spent half of their money on rides so amount spent on rides = = $2x
Then they each spent $3 on food so total money spent = $(2x + 12)
Remaining money = $8
Now the equation will be
$4x - $(2x + 12) = $8
4x - 2x - 12 = 8
2x - 12 = 8
2x = 12 + 8
x = $10
Therefore, each friend spent $10.

You are running a fuel economy study. One of the cars you find is blue. It can travel 33 1/2 miles on 1 1/4 gallons of gasoline. Another car is red. It can travel 21 3/5 miles on 4/5 gallons of gasoline. What is the unit rate for miles per gallon for each car? Which car could travel the greater distance on 1 gallon of gasoline?
Answers
Answer:
1) blue car 28.4 miles per gallon
2) miles per gallon
3) Blue car
Step-by-step explanation:
In order to get the unit rate, we must divide the miles by the gallons so
Blue car: 33.5 / 1.25 = 28.4
Red car: 21.6 / 0.8 = 27
The blue car travels a greater distance on 1 gallon since 28.4 > 27

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.

Answers
Answer:
They can never be similar because their sides can never be proportional and their angles can never be congruent.
Step-by-step explanation:
Hope It Helps
I did the k12 test!!
They can never be similar because their angles can never be equal and their sides can never be proportional.
What are Similar Triangles?Two triangles are said to be similar if the triangles are of the same shape but different size. The angles of the triangle will be equal and the sides are proportional.
An equilateral triangle has all the sides and angles equal to each other.
Any similar triangle for an equilateral triangle will have the sides proportional.
Since all the sides are equal, the similar triangle will also have all the sides equal which may be different from the original triangle.
So this can never be similar to a scalene triangle where all the sides are of different length.
Hence the correct reason is that, their angles can never be equal and their sides can never be proportional.
