Answer:
A. Total area of Alaska is considerable larger than total area of Connecticut.
B. Population of California is considerably larger that population of Alaska.
Step-by-step explanation:
A. What is the difference in total area of Alaska and Connecticut?
According to the US government, total areas of Alaska and Connecticut are 663,268 square miles ([tex]6.633\times 10^{5}[/tex] square miles) and 5,567 square miles ([tex]5.567\times 10^{3}[/tex] square miles), respectively.
The difference between both quantities is:
[tex]x = 6.633\times 10^{5}\,mi^{2}-5.567\times 10^{3}\,mi^{2}[/tex]
[tex]x = 6.577\times 10^{5}\,mi^{2}[/tex]
Which means that total area of Alaska is considerable larger than total area of Connecticut.
B. What is the difference in total population of California and Alaska?
According to the US government, total populations of California and Alaska are 39,512,223 people ([tex]3.951\times 10^{7}[/tex] people) and 710,249 people ([tex]7.103\times 10^{5}[/tex] people), respectively.
The difference between both quantities is:
[tex]x = 3.951\times 10^{7}\,people - 7.103\times 10^{5}\,people[/tex]
[tex]x = 3.880\times 10^{7}\,people[/tex]
Which means that population of California is considerably larger that population of Alaska.
11. Find the measure of
Answer:
kpm is about 110.02 degrees
Step-by-step explanation:
-kpl and npm are vertical angles, so they're congruent
-npm and lpm are supplementary angles, meaning they add to 180 degrees
we r given:
npm = 14x - 22
lpm = 7x + 4
add these and set equal to 180:
14x - 22 + 7x + 4 = 180
then combine like terms:
21x -18 = 180
isolate the variable by adding 18 on both sides:
21x = 198
divide by 21 on both sides:
x = about 9.43
since kpl and npm r congruent, plug in the value of x in npm (14x-22):
14(9.43)-22
= 110.02
Triangle XYZ is rotated to create the image triangle X'Y'Z'.
On a coordinate plane, 2 triangles are shown. The first triangle has points X (negative 2, 2), Y (1, 2), Z (0, 4). The second triangle has points X prime (2, negative 2), Y prime (negative 1, negative 1), Z prime (0, negative 4).
Which rules could describe the rotation? Select two options.
R0, 90°
R0, 180°
R0, 270°
(x, y) → (–y, x)
(x, y) → (–x, –y)
Answer:
The correct option is;
R0, 180°
Step-by-step explanation:
The coordinates of ΔXYZ are given as follows;
X(-2, 2), Y(1, 2), Z(0, 4)
The coordinates of ΔX'Y'Z' are given as follows;
X'(2, -2), Y'(-1, -1), Z'(0, -4)
Whereby, the coordinates of the point Y' is (-1, -2), we have the rule that describe the transformation of ΔXYZ to ΔX'Y'Z', given as follows
Coordinates of the preimage = (x, y)
Coordinates of the image = (-x, -y)
Which is in accordance with the transformation by rotation 180° about the origin.

Step-by-step explanation:
x+4 over x^2-5x+6 ÷ x^2-16 over x+3
Answer:
x =± 4
Step-by-step explanation:
Solve for x:
x^2 - 16 = 0
The left hand side factors into a product with two terms:
(x - 4) (x + 4) = 0
Split into two equations:
x - 4 = 0 or x + 4 = 0
Add 4 to both sides:
x = 4 or x + 4 = 0
Subtract 4 from both sides:
Answer: x =± 4
Answer: (x + 3) / (x - 2)(x - 3)(x - 4)
Step-by-step explanation:
The problem given can be viewed as
a/b over c/d
where a/b is the top fraction and c/d is the bottom fraction.
This can be rearranged to
a × d / b × c
So, you will have:
(x + 4)(x + 3) / (x² - 5x + 6)(x² - 16)
Now, factor the two bottom polynomials so you end up with:
(x + 4)(x + 3) / (x - 2)(x - 3)(x + 4)(x - 4)
Cancel the (x + 4) on the top and bottom so you’re left with the answer:
(x + 3) / (x - 2)(x - 3)(x - 4)
If you need to find the solutions to x, set the denominator equal to zero.
x = 2
x = 3
x = 4
Sydney and Elijah are working on creating a garden. They go to the store and buy 29 flower stems and spent $120.94. Elijah and Sydney only bought lilies and peonies, lilies cost $3.42 per stem and peonies cost $4.78 per stem. How many lily stems did they buy? How many peony stems did they buy?
Given:
Total number of flower they buy = 29 stems
Total cost = $120.94
Lilies cost = $3.42 per stem
Peonies cost = $4.78 per stem
To find:
The number of lily stems and peony stems did they buy.
Solution:
Let number of lily stems = x
Number of lily stems and peony stems = y
According to given information,
[tex]x+y=29[/tex] ...(i)
[tex]3.42x+4.78y=120.94[/tex] ...(ii)
From (i) and (ii), we get
[tex]3.42x+4.78(29-x)=120.94[/tex]
[tex]3.42x+138.62-4.78x=120.94[/tex]
[tex]-1.36x=120.94-138.62[/tex]
[tex]-1.36x=-17.68[/tex]
Divide both sides by -1.36.
[tex]x=\dfrac{-17.68}{-1.36}[/tex]
[tex]x=13[/tex]
Put x=13 in (i).
[tex]13+y=29[/tex]
[tex]y=29-13[/tex]
[tex]y=16[/tex]
Therefore, number of lily stems is 13 and number of lily stems and peony stems is 16.
A set of numbers is given below.
{v/72 9.25, /83, pi 2 8.7}
Which list correctly orders the numbers from least to greatest
Answer:
Option (2)
Step-by-step explanation:
From the given set of numbers we have to arrange them in the increasing order.
{[tex]\sqrt{72},9.25,\sqrt{83},\pi^2,8.7[/tex]}
Since, [tex]\sqrt{72}=8.49[/tex]
[tex]\sqrt{83}=9.11[/tex]
[tex]\pi ^2[/tex] = 9.87
Therefore, set of numbers will be in the form of,
{8.49, 9.25, 9.11, 9.87, 8.7}
Now arranging these numbers in the increasing order,
8.49 < 8.7 < 9.11 < 9.25 < 9.87
Therefore, numbers in the increasing order will be,
{[tex]\sqrt{72},8.7,\sqrt{83},9.25,\pi ^{2}[/tex]}
Option (2) will be the answer.

Jordan has three $100 bills, four $20 bills, one $10 bill, and eight $1 bills. What will Jordan’s total be if Jayla gives him one more $20 bill? Jordan’s total will be Fill in the blank text field 1 . What will his total be if she gives him one more $100 bill instead? Jordan’s total will be Fill in the blank text field 2
Answer:
$418
$498
Step-by-step explanation:
Jordan has - 3 * $100 = $300,
4 * $20 = $80,
1 * $ 10 = $10,
8 * $1 = $8
Total = $398
Jordan’s total will be $418 if Jayla gives him one more $20 bill?
Jordan’s total will be $498 if Jayla gives him one more $100 bill?
Jordan's total will be $438 if Jayla gives him one more $20 bill.
Jordan's total will be $498 if Jayla gives him one more $100 bill.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If Jayla gives Jordan one more $20 bill, then Jordan will have:
3 x $100 = $300
5 x $20 = $100
1 x $10 = $10
8 x $1 = $8
1 x $20 = $20
Adding these up gives:
$300 + $100 + $10 + $8 + $20 = $438
Jordan's total will be $438 if Jayla gives him one more $20 bill.
If Jayla gives Jordan one more $100 bill instead, then Jordan will have:
4 x $100 = $400
4 x $20 = $80
1 x $10 = $10
8 x $1 = $8
Adding these up gives
$400 + $80 + $10 + $8 = $498
Therefore,
Jordan's total will be $438 if Jayla gives him one more $20 bill.
Jordan's total will be $498 if Jayla gives him one more $100 bill.

45% of a number is 180. Find the number
Answer:
400
Step-by-step explanation:
Let the number be known as "x".
Given statement:
45% of a number is 180.
The term "of" defines multiplication between two terms. In this case, the terms are 45% and the number "x". Therefore,
⇒ 45% × x = 180
When we convert a percentage into a fraction, simply divide the percentage by 100 and remove the percentage sign to obtain the result in fraction form.
⇒ 45/100 × x = 180
Multiplying 45/100 and x:
⇒ 45/100 × x = 180
⇒ 45x/100 = 180
Using cross multiplication:
⇒ 45x/100 = 180
⇒ 45x = 180 × 100
Simplifying the right-hand-side:
⇒ 45x = 180 × 100
⇒ 45x = 18000
Dividing 45 to both sides of the equation:
⇒ 45x = 18000
⇒ 45x/45 = 18000/45
⇒ x = 18000/45 = 400
Therefore, the number is 400.
three consecutive even numbers whose sum is -42
Answer:
-12, -14, -16
Step-by-step explanation:
x + (x+2) + (x+4) = -42
3x + 6 = -42
Isolate the variable 3x by subtracting 6 from both sides
3x = -48
Then isolate the variable x by dividing 3 from both sides
x = -16
Then add 2 for the 2nd number
Then add 4 for the third number
