According to the solving the total and the difference of the numbers:
total = 136 + 64
difference = 64
Difference in Math Definition?Mathematical difference is the outcome of one of the key operations, which is the subtraction of two numbers. It reveals the margin of difference between two numbers.
How do we find the difference?Subtract the largest number from the lowest number to determine the difference between two integers. The difference between these two numbers is the product of this sum. As a result, there are 55 between the numbers 45 and 100.
According to the given data:Let the numbers be x and y
Given,
x+y = 200_____(1)
x-y = 72_____(2)
Add above 2 eq.
2x= 272
x= 136
Substitute the value of x in eq 1,we get
136+y = 200
y = 64

even integers have a difference of 2 since the next even integer is after an odd integer. Hence, x+2 is the next even integer after x.
Suppose a study is completed that finds that the number of cockroaches in chandler decreases by 18% every 12 years. I’m 2020, there were approximately 3.5 million cockroaches in chandler.
The number of cockroaches in Chandler in the year 2025 will be 3237500 or 3.23 million approx
Approx number of cockroaches in the year 2020 in Chandler = 3500000 or 3.5 million
Percentage decrease in cockroaches every 12 years = 18%
Percentage decrease in cockroaches every year = 18/12 = 1.5%
So, in 5 years the percentage decrease in cockroaches will be = Percentage decrease every year*No. of years = 1.5*5 = 7.5%
The number of cockroaches in 2025 will be: 3500000 - 7.5% of 3500000
= 3500000 - 7.5/100*3500000
= 3500000 - 262500
= 3237500
Hence, the number of cockroaches in Chandler in the year 2025 will be 3237500 or 3.23 million approx

Answer:
34%
Step-by-step explanation:
In the sample of 300 voters, 102 said they would vote for brown. The sample statistic is just the percent given by the sample. Find the percent by dividing the voters who said they'd vote for brown by the entire sample group:
[tex]\frac{102}{300}=0.34[/tex]
Convert this to a percentage:
34%
the sample statistic for the percentage of voters surveyed who said they would vote for Brown is 34%.
How do we explain?we start by divide the number of voters who said they will vote for Brown by the total number of voters surveyed and then multiply by 100.
Number of voters surveyed (n) = 300
Number of voters who said they'd vote for Brown = 102
The Sample statistic for the percentage of voters who said they would vote for Brown:
Percentage of voters for Brown = (Number of voters for Brown / Number of voters surveyed) * 100

Keep the Old Car or Buy a Used Car
Manny is an online student who currently owns an older car that is fully paid for. He drives, on average, 110 miles per week to commute to work. With gas prices currently at $ 2.05 per gallon, he is considering buying a more fuel-efficient car, and wants to know if it would be a good financial decision.
The old car Manny owns currently gets 17 miles per gallon for average fuel efficiency. It has been a great vehicle, but with its age, it needs repairs and maintenance that average $ 870 per year (as long as nothing serious goes wrong).
The newer, more fuel-efficient car that he is looking at to purchase will cost a total of $ 8,000 over a three-year loan process. This car gets 32 miles per gallon and would only require an average of $ 10 per month for general maintenance. To help make a decision, Manny wants to calculate the total cost for each scenario over three years. He decides to use the quantitative reasoning process to do this.
The total cost of using the old car is $4,679.29
The total cost of using the newer car is $ 8,896.25.
What are the total costs?The total cost of using the old car: (cost of maintenance x number of years) + ( miles driven to work / miles per gallon x cost per gallon x number of weeks in a year x number of years)
($870 x 3) + (110 / 17 x $2.05 x 52 x 3)
$2,610 + 2069.29 = $4,679.29
The total cost of using the newer car : purchase price + (cost of maintenance per month x number of months in year x number of years) + (miles driven to work in a week / number of miles per gallon x weeks in year x number of year)
$8000 + ($10 x 12 x 3) + (110 / 32 x 52 x 3)
$8000 + 360 + 536.25 = 8,896.25

The second angle of a triangle is five times as large as the first. The measure
of the third angle is 12 degrees greater than that of the first angle. What is
the measurement of the largest angle?
Answer:
120
Step-by-step explanation:
consider
1st angle= a
2nd angle = b
3rd angle = c
now,
b=5a ............. equation 1
c = a+12 ........ equation 2
as we know in a triangle, sum of all angle is 180.
so
a+b+c = 180
=> a +5a + (a+12 ) = 180
=> 7a = 180-12 =168
=> a = 168/7 = 24
so a= 24
b = 5(24) = 120
c = a+12 = 24+12 =36
so b = largest = 120

find the point of intersection y=4x-1 y=-2x+5
The point of intersection of the given two lines y = 4x - 1 and y = -2x + 5 is (1, 3).
According to the given question.
We have two equations
y = 4x - 1 ..(i)
and
y = -2x + 5 ..(ii)
As we know that, the point at which two lines intersect is called point of intersection.
Therefore, the point of intersection for the two lines y = 4x - 1 and y = -2x + 5 is given by
Subtracting equation ii from i
y - y = 4x - 1 + 2x -5
⇒ 0 = 6x - 6
⇒ 6x = 6
⇒ x = 1
Substitute the value of x in (i).
y = 4 - 1 = 3
Hence, the point of intersection of the given two lines y = 4x - 1 and y = -2x + 5 is (1, 3).

Answers:
smallest = 843 milesmedium = 922 mileslargest = 1299 miles=========================================================
Work Shown:
x = smallest side
y = medium side
z = largest side
x = y-79
z = y+377
x+y+z = perimeter
x+y+z = 3064
(y-79) + (y) + (y+377) = 3064
3y + 298 = 3064
3y = 3064-298
3y = 2766
y = 2766/3
y = 922
x = y-79
x = 922-79
x = 843
z = y+377
z = 922+377
