The value of x as an int variable is 0
What is a int variable?An int(integer) variable is a variable containing only whole numbers.
Given the expression;
x = - 3 + 4 % 6/ 5
Let's make into proper fraction, we have
x = - 3 + {}4/ 100 × 6/ 5
Multiply through
x = -3 + 6/ 5/ 4/ 100
x = -3 + {6/ 5 ÷ 0. 4}
x = -3 + {3}
expand the bracket
x = -3 + 3
Add like terms
x = 0
Thus, the value of x as an int variable is 0

Which statements have an inverse that is false?
1.If two angles are congruent, then they are vertical angles.
2.If two angles are a linear pair, then they are supplementary.
3.If two angles are acute, then their sum is less than 90.
4.If two angles are complementary, then both angles are acute.
Answers
Statement 1 is a false statement.
What are supplementary angle?
Supplementary angles are two angles whose measures add up to 180° . ex 150° and 30°
What are complementary angles?
When the sum of two angles is equal to 90° degrees, they are called complementary angles. For example, 30° and 60° are complementary angles.
What are vertical angles?
Vertical angles are formed when two lines meet each other at a point. A vertical angle and its adjacent angle are supplementary angles, i.e., they add up to 180°What are congruent angles?
Two or more angles that are identical to each other.
False - All vertical angles are considered congruent but not all congruent angles are considered vertical angles. Any acute or obtuse angle may also be considered congruent. True - If 2 angles whose measures add to 180°, it means they are supplementary. They form a linear pair.True - Let one angle be 30° and the other angle is 40° , both of which are acute angles, then their sum is 70°, which is less than 90° True - Both angles in a complementary pair will always be acute. For ex: 30° and 60° are complementary angles , but are less than 90°, so they both are acuteThus we can conclude that all vertical angles are congruent but not all congruent angles are considered vertical angles

The population of Georgia is growing at a yearly rate of about 1.3%. The current population is
about 9,815,210 people. The population of North Carolina is growing at a yearly rate of about
1.25%. North Carolina's current population is about 9,656,401 people.
a. What is the equation that models Georgia's population growth?
b. What is the equation that models North Carolina's population growth?
c. What do the graphs of the equations look like? Graph the equations on the provided grid.
Answers
The equation for population growth in Georgia is P = 8,815,210 ( 1.013 )ⁿ ( red line on the graph) and the equation for population growth in North Carolina is P = 9,656,401 ( 1.0125)ⁿ ( blue line on the graph).
We are given that:
For Georgia:
Growth rate of population = 1.3 %
Population = 8,815,210
For North Carolina:
Growth rate of population = 1.25 %
Population = 9,656,401
a) The equation that models Georgia's population growth can be found out by using the concept of compound interest as the population will increase in a compounded way.
So, the equation will be:
P = 8,815,210 ( 1 + 1.3 % )ⁿ
P = 8,815,210 ( 1.013 )ⁿ
where P is the population after n years.
b) the equation that models North Carolina's population growth:
P = 9,656,401 ( 1.0125)ⁿ
where P is the population after n years
Therefore, we get that, the equation for population growth in Georgia is P = 8,815,210 ( 1.013 )ⁿ ( red line on the graph) and the equation for population growth in North Carolina is P = 9,656,401 ( 1.0125)ⁿ ( blue line on the graph)

Answers
The statement can be proved by the law of syllogism.
A formal logical framework used to infer a conclusion from a series of premises is referred to as a syllogism, also known as a rule of inference.
The law of syllogism in conditional statement is given as:
if p then r and if r then q , then we can state that if p then q , where p , q, and r are statements.
Now in the given conditional statements we can write it as:
let p = You go camping
r = you will need a flashlight
q = you will need extra batteries.
Now it is given the if p then r and again if r then q , so by using the law of syllogism we can state that if p then q , that is

Let x represent the length of one side of the square patio. Write expressions
for the length and width of the new patio. Then find the area of the new patio
if the original patio measures 8 feet by 8 feet.
Answers
Answer:
Length = x + 3 ft
Width = x - 3 ft
Area of new patio = x² - 9 sq ft
If original side length = 8, new area = 55 sq ft
Step-by-step explanation:
The original patio has side length of x
If one side is reduced by 3 we get (x - 3) as the new side
If the side is increased by 3' we get (x + 3) as the new side
Area of new Patio = (x - 3)(x+3) = x² - 9
Original patio is 8 x 8
New patio width = 8 - 3 = 5
New patio length = 8 + 3 = 11
Area = 5 x 11 =55 sq ft

Suppose x and y vary together such that y = 2 x 8 . suppose x varies from x = 3 to x = 9.5 . over this interval, how much does x change by?
Answers
A function assigns the values. The value of x changes by 6.5, and the value of y changes by 13.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given that x and y vary together such that y = 2x+8. Also, the of x varies from x = 3 to x = 9.5. Therefore, we can write,
x change by = Maximum value of x - Minimum value of x
= 9.5 - 3
= 6.5
Further, the minimum and the maximum value of y will be when the value of x is minimum and maximum, this is because the function is linear. Therefore, we can write,
Minimum value of y, y = 2(3) - 8 = -2
Maximum value of y, y = 2(9.5) - 8 = 11
y change by = Maximum value of y - Minimum value of y
= 11 - (-2)
= 11 + 2
= 13
Hence, the value of x changes by 6.5, and the value of y changes by 13.

The total weight of the two animals is 1.2 x 10^5 lbs
How to determine the total weight of the two animals?The given parameters are
Animal 1 = 5.36 x 104 lbs.
Animal 2 = 6.2 x 104 lbs
Rewrite the parameters properly
Animal 1 = 5.36 x 10^4 lbs.
Animal 2 = 6.2 x 10^4 lbs
The total weight of the two animals is calculated as
Total weight = Animal 1 + Animal 2
This gives
Total weight = 5.36 x 10^4 lbs + 6.2 x 10^4 lbs.
Factor out 10^4 lbs
Total weight = (5.36 + 6.2) x 10^4 lbs.
Evaluate the sum
Total weight = 11.56 x 10^4 lbs.
Rewrite as
Total weight = 1.156 x 10^5 lbs.
Approximate
Total weight = 1.2 x 10^5 lbs.
Hence, the total weight of the two animals is 1.2 x 10^5 lbs
