Answer:
I don't think anyone is going to answer ALL of those questions but ill get you started...
Step-by-step explanation:
1: 7.8 billion. Used billions as my unit. Did not use a site, I already knew this information.
2: The population has increased by approximately 12% in the last 10 years. Worldometer.com shows this information.
3: 1950 population: 2.5 billion, 1960 population: 3.039 billion. The population comparison can be achieved by looking at the increase in billions. The increase was almost 0.6 billion.
Hopefully, that can get you started.
One year, the population of a city was 51,000. Several years later it was 44,880. Find the percent decrease.
The percent decrease in the population is 12%
What is a percent?Percentages are essentially fractions where the denominator is 100.
Given that, the population of a city was 51,000. Several years later it was 44,880.
We are asked to find percent decrease,
Percent decrease = Final element - initial element / initial element x 100
Percent decrease = 44880 - 51000 / 51000 x 100
= -6120 / 51000 x 100
= --0.12 x 100
= -12%
Here, - sign is showing the decrease.
Hence, the percent decrease in the population is 12%

Step-by-step explanation:
QUESTION 7:
We are trying to find angles 1 and 2.
Known angle: 107˚.
In this question, we have 2 parallel lines with a transversal. A transversal is a line that passes through 2 parallel lines making it so that the angles on both sides are exactly the same.
Step 1: Find the measures of all the angles using the one we already know.
I will start with the angle adjacent (right next to) the angle that measures 107˚. As you can see, it is a supplementary angle because both of them form a straight line, or 180˚.
Therefore,
107+x= 180
x= 180-107
x= 73˚
Next, I will find the measure of the angle that is vertical to the one that measures 107˚. Note that angles that are vertical to each other are always identical, or in other words they have the same measure. Hence, the angle "vertical", or opposite to the one that measures 107˚ has to measure 107˚ as well. You can also tell this is true because they look the same.
Now I'll find the measure of the angle vertical to the one that measures 73˚. As we know, vertical angles are identical, so the one vertical to it is 73˚.
Here, I'll solve for angles 1 and 2. Like I said earlier, when a transversal crosses through 2 parallel lines, there will be 2 sets of angles that all have the same measurements.
To solve for angle 1, simply know what angle is right below it, and that is the one that measures 107˚. (If you look at the 2 lines, you will see that both angle sets are essentially duplicates of each other.) Likewise, angle 2 has to be 73˚ because the one under it is also 73˚.
Angle 1: 107˚
Angle 2: 73˚
QUESTION 8:
Again, we have a transversal that passes through 2 parallel lines. One angle measures 95˚. When there are 3 seperate angles along a straight line, the one next to the one with the given measurement will be the same as that one.
So angle 3 is 95˚. To find angle 4, find the angle measurement that's vertical to angle 3, which is 95˚. Now, since that angle and angle 4 are supplementary (both form a straight line which is always 180˚), 95+x= 180.
(x stands for angle 4)
x+95= 180
x= 180-95
x= 85
Angle 4= 85˚.
QUESTION 9:
ANGLE 5: 49˚
When there is a transversal, there are 2 identical pairs of angles. Therefore, angle 5 must be 49˚.
ANGLE 6: 131˚
angle 5 and angle 6 form a straight line which means they are supplementary angles. Therefore, both angles must add up to 180˚. So 49+x= 180
x= 180-49= 131
(x stands for angle 6)

The table shows the proportional relationship between the number of tickets required per game at a carnival.
Games 3 9 15
Tickets 12 36 60
Determine the constant of proportionality.
Answer:
4
Step-by-step explanation:
Divide the larger number (tickets) by the smaller number (games):
12 / 3 = 4
36 / 9 = 4
60 / 15 = 4
The required value of the contant of proportionality is given as 1/4.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
Let G be the number of games and T be the number of tickets,
G ∝ T
So,
G = kT
From the table,
3 = 12k
T = 3 / 12
T = 1/4
Thus, the required value of the contant of proportionality is given as 1/4.

2.) There are three nickels, four dimes, and four quarters in your pocket. You randomly pick three coins and place them on a counter. The first coin is a nickel, the second is a dime, and the third is a quarter.
A..3/110,
b.8/165,
c. 1/64,
d.10/273
Answer:
B.
Step-by-step explanation:
Total coins = 11 ( 3 + 4 + 4 = 11).
The probability of picking a nickel first = 3/11 ( 4 nickels out of 11 total).
The probability of picking a dime second = 4/10 = 2/5 ( 3 dimes out of 10 coins left).
The probability of picking the third coin as a quarter = 4/9 ( 3 quarters out of 9 coins left).
The probability of picking all three in that order = 3/11 x 2/5 x 4/9 = 8/165

The required distance between the points (−5, −3) and (−10, −8) is the square root of 50 units. Option C is correct.
What is Distance?Distance is defined as the object traveling at a particular speed in time from one point to another. And also the distance is the measure of length between two points.
Here,
The distance between the points (−5, −3) and (−10, −8) is given by the distance formula is given as,
D = √[[x₂ - x₁]² + [y₂+ - y₁]²]

For an equation with fractions, why is it helpful to multiply both sides of the equation by the LCD?
Answer:
You can just cancel out on both sides and find the value of the variable.
By multiplying the lowest common denominator the denominator from both sides got canceled and we get a variable value.
What is multiplication?Multiplication is the general procedure in mathematics in which we multiply two or more numbers to each other to find a new multiplied number.
Multiplication gives us a resultant number that will be very big as compared to the number which is going to be multiplied if and only if the number which is going to be multiplied is more than one.
Let's consider an equation
x/2 = 1/6
Now lowest common denominator is 2 among 6, 2
So by multiplying 2 on both sides
2(x/2) = 2(1/6)
x = 1/3
Hence multiplication of the lowest common denominator is helpful to simplify the equation to get the variable or remove fraction.

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.

Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.
