A star patterned quilt has a star with the angels shown. What is the value of x? Explain your answer.
Answer:
81°
Step-by-step explanation:
x° and 24° are interior angles of a triangle that are opposite to an exterior angle of measure 105°. According to the exterior angle theorem of a triangle, thus:
[tex] x + 24 = 105 [/tex]
Subtract 24 from both sides
[tex] x + 24 - 24 = 105 - 24 [/tex]
[tex] x = 81 [/tex]
Value of x = 81°
Write the letters of the expressions that are equivalent to the given expression.
5(2x + 3)
a. 10x + 15
b. 5x + 15x + 5x
c. 10x + 8
Answer: A.) 10x + 15
Step-by-step explanation:
You would distribute (multiply) the 5 to the 2x which would then make it 10x and you would distribute (multiply) the 5 to the 3 which would then make it 15. Because the 5 is a positive number the sign stays the same.
Therefore, 10x + 15 is your answer.

Which of the following could be the perimeters of the three squares below?
A 12ft, 16 ft and 20 ft
B 20 ft, 16 ft and 24 ft
C) 40 ft, 80 ft and 120 ft
D 16 ft, 24 ft and 28 ft
Answer:
Option (A)
Step-by-step explanation:
Option (A).
Since, perimeter of a square = 4×(side)
Perimeters of 3 squares = 12 ft, 16 ft and 20 ft
Side lengths of three squares will be = [tex]\frac{12}{4}, \frac{16}{4},\frac{20}{4}[/tex]
= 3 ft, 4 ft and 5 ft
If these sides are the measures of the sides of the given right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
5² = 4² + 3²
25 = 16 + 9
25 = 25
True.
Therefore, these are the sides of the given right triangle.
Option (B).
Perimeters of three squares are 20 ft, 16 ft and 24 ft.
Sides lengths of three squares = [tex]\frac{20}{4},\frac{16}{4}, \frac{24}{4}[/tex]
= 5 ft, 4 ft and 6 ft
By Pythagoras theorem,
6² = 4² + 5²
36 = 61
False.
Therefore, these sides are not of the given right triangle.
Option (C)
Perimeters of the squares = 40 ft, 80 ft and 120 ft
Side lengths of the squares = 10 ft, 20 ft and 30 ft
If these sides are the sides of the given right triangle, they will follow the Pythagoras theorem.
By Pythagoras theorem,
(30)² = (10)² + (20)²
900 = 500
False.
Option (D)
Perimeters of the given squares are 16 ft, 24 ft and 28 ft.
Side lengths of these squares will be 4 ft, 6 ft and 7 ft.
If these sides form a right triangle they will follow the Pythagoras theorem.
By Pythagoras theorem,
7² = 4² + 6²
49 = 16 + 36
49 = 52
False.
Therefore, these are not the sides of a right triangle.

if R is the midpoint of QS, RS = 2x-4, ST = tx-1, and RT = 8x-43
The question is incomplete. Here is the complete question.
If R is the midpoint of QS, [tex]RS=2x-4[/tex], ST = [tex]4x-1[/tex] and RT = [tex]8x-43[/tex], find QS.
Answer: QS = 68 units
Step-by-step explanation: The figure below shows a line segment QT.
To determine QS, first, determine value of x:
RT = RS + ST
[tex]8x-43=2x-4+4x-1[/tex]
[tex]8x-43=6x-5[/tex]
2x = 38
x = 19
Now, we determine QS:
Midpoint is a point dividing a line segment in two equal parts.
Then, QR = RS.
QS = QR + RS
QS = 2RS
[tex]QS=2(2x-4)[/tex]
[tex]QS=4x-8[/tex]
Substituting x = 19:
[tex]QS=4.19-8[/tex]
QS = 68
The segment QS is 68 units.
Answer: x = 1
Step-by-step explanation:
I have no idea what the actual answer is, as you didn't ask a question. So i'm assuming that you want the value of x.
Step 1: Draw a line containing all the points
R is in between point Q and point S, while T is last, based on alphabetical order.
Illustration:
2x - 4 Tx - 1
Q R S T
8x - 43
Step 2: Find T's value
To find t, create the substitution equation RS + ST = RT
2x - 4 + tx - 1 = 8x - 43
-2x -2x
-4 + tx - 1 = 6x - 43
tx - 5 = 6x - 43
tx = 6x - 38
tx/x = 6x/x - 38
t = 6 - 38
t = -32
This is the value of t
By the way, there is no correlation between point T and the variable t.
Step 3: Find x's value
Now that we know what t is, we can solve for x
2x - 4 -32x - 1 = 8x - 43
-30x - 5 = 8x - 43
+30x +30x
-5 = 38x - 43
+43 +43
38 = 38x
38/38 = 38x/38
1 = x
This is the value of x
The local diner offers a meal combination consisting of an appetizer, a soup, a main course, and a dessert. There are six appetizers, two soups, four main courses, and six desserts. Your diet restricts you to choosing between a dessert and an appetizer. (You cannot have both.) Given this restriction, how many three-course meals are possible?
Answer: 96
Step-by-step explanation:
According to the fundamental principle of counting:
Total number of meals possible = (Choices for appetizers) x (Choices for soups) x (Choices for main courses) x (Choices for desserts)
If there is a restriction to choose between appetizer and dessert.
Then, Total number of meals possible = (Choices for appetizers) x (Choices for soups) x (Choices for main courses) + (Choices for soups) x (Choices for main courses) x (Choices for desserts)
= 6 x 2 x 4 + 2 x 4 X 6
= 48+48
= 96
Hence, the number of three-course meals are possible= 96

96?

The order of letters in triangle's "names" is important, it indicates the corresponding angles and sides.
∠J ≅ ∠X, ∠K ≅ ∠Y, ∠L ≅ ∠Z
segment JK ≅ segment XY,
segment KL ≅ segment YZ,
segment JL ≅ segment XZ
m∠Z = m∠L = 180° - (60° + 55°) = 65°
(4a + 9)° = 65°
4a = 65 - 9 ⇒ a = 14
XY = JK = 24 units
3b - 6 = 24 ⇒ b = 10

You now have an equation to model the finances of the car wash. What is the value of the profit when the baseball team washes 0 cars? What point represents the value? What does the y-value of this point mean in terms of the problem?
Answer:
The equation for the profit made on the car wash is y = 5x – 75. Here, y is the profit made and x is the number of cars washed. So if the team washes 0 cars, x will be 0.
y = 5(0) – 75
y = -75
The point that represents this is (0, -75). Here, the value of the y-coordinate of the point is -75. Since it has a negative sign, it means that instead of making a profit, the team suffers a loss. So, if the baseball team washed no cars, it would lose $75.

Each Christmas elf makes x toys in an hour. n elves work for t hours to produce 1000 toys.
Write an equation that relates x, n, and t.
Answer:
e(X x T)=1000
Step-by-step explanation:
You do the number of toys they make(X) times the hours they work(T). Then multiply all of it by the number of elves(e). All of that equals the 1000 toys they make all together.
Equation relates x, n and t is n × x × t = 1000
What is an equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Each elf makes x toys in an hour
one elf will make x × t toys in t hours
n elf will make 1000 toys in t hours
So n elf will make 1000 toys in t hours
n × x × t = 1000
Hence, the equation relate x, n and t is n × x × t = 1000

The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
Total value = b
Percentage = a/b x 100
The percent modeled is 9%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
Total value = b
Percentage = a/b x 100
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of cells in the box = 100
Number of shaded cells = 9
The percentage of the shaded cells.
= (Number of shaded cells / Total number of cells) x 100
= 9/100 x 100
