How many times bigger is Mars than Pluto?
Main Answer:
Mars is bigger than Pluto by 27 times.
Explanation:
Volume is defined as the space occupied within the boundaries of an object in three-dimensional space.It is also termed as the capacity of the object.Given: Volume of Mars = [tex]1.31[/tex] × [tex]10^{21} m^{3}[/tex]
Volume of Pluto = [tex]4.93[/tex] × [tex]10^{19} m^{3}[/tex]
To find: Determine how many times bigger is Mars than Pluto.
No. of times bigger = [tex]\frac{Volume of Mars}{Volume of Pluto}[/tex]
= [tex]\frac{1.31 * 10^{21} m^{3} }{4.93 * 10^{19}m^{3} }[/tex]
= [tex]\frac{131}{493} * 10^{2}[/tex]
=0.2657 × 100
= 26.57
=27
Final Answer:
Therefore, 27 times bigger is Mars than Pluto.

The measure of the angle JL is 33 degrees
Bisection of anglesA bisection is a line that divides an angle into two equal portion. Using the addition postulate below:
<JKM = <JKL + <LKN + <NKM
If the line KN bisects <LKM then <LKN = <NKM = 22 degrees
Substitute the given parameters
<JKM = <JKL + <LKN + <NKM
77 = <JKL + 22 + 22
77 = <JKL + 44
<JKL = 77 - 44
<JKL = 33 degrees
Hence the measure of the angle JL is 33 degrees

(1) LM = MP (2) M is the midpoint of LP (3) LM +MP=180 (4) M bisects LP
The statement that is false about the relationship of L, M, and P that are collinear is: 3. LM + MP = 180.
What are Collinear Points?When two or more points are on a straight line, they are classified as collinear points.
What is the Midpoint of a Segment?The point on a line segment that bisects the segment into two equal parts is referred to as the midpoint of the line segment.
We are given that:
LM = MP, since, points L, M. and P are collinear points, therefore, it implies that point M is the midpoint of segment LP.
It also means that M bisects segment LP since LM = MP, where M is the midpoint of segment LP.
Thus, the statement that is false about the relationship of L, M, and P that are collinear is: 3. LM + MP = 180.

Step-by-step explanation:
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.
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)

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.

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

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}

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?
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.
