(−5/7)^8⋅(−5/7)^9
The expression [tex](-5/7)^8*(-5/7)^9[/tex] simplifies to [tex](-5/7)^{17[/tex] by adding the exponents, as multiplication of powers with the same base results in adding the exponents.
To simplify the expression [tex]\((-5/7)^8 \cdot (-5/7)^9\)[/tex], you can add the exponents since the bases are the same. When you multiply two powers with the same base, you add their exponents. So, [tex]\(8 + 9 = 17\)[/tex]. Therefore, the expression simplifies to [tex]\((-5/7)^{17}\)[/tex]. When multiplying powers with the same base, like [tex]\((-5/7)^8\)[/tex] and [tex]\((-5/7)^9\)[/tex], you add their exponents. So, [tex]\(8 + 9 = 17\)[/tex].
This means that when you multiply these two expressions together, you end up with the base raised to the power of 17, which is [tex]\((-5/7)^{17}\)[/tex]. This is a fundamental property of exponents, where you can combine like terms to simplify expressions. In this case, the final expression represents the product of the two original expressions raised to the power of 17.
So, the simplified expression is [tex]$(-5 / 7)^{17}$[/tex]
To simplify the expression [tex]$(-5 / 7)^8 \cdot(-5 / 7)^9$[/tex] we can combine the bases and add the exponents since they have the same base:
[tex]$\begin{gathered}(-5 / 7)^8 \cdot(-5 / 7)^9=(-5 / 7)^{8+9} \\ =(-5 / 7)^{17}\end{gathered}$[/tex]

Find the missing side length in the following triangle.
A 169
B 10
C 1
D 13
The missing side length in the triangle with a hypotenuse of 85 and perpendicular of 84 is 13.
To find the missing side length a in the right triangle, you can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
So, in this case, we have:
[tex]\[ \text{hypotenuse}^2 = \text{perpendicular}^2 + \text{base}^2 \][/tex]
Given:
- Hypotenuse ( c ) = 85
- Perpendicular ( b ) = 84
- Base ( a ) = ?
Substituting the given values into the Pythagorean theorem equation:
[tex]\[ 85^2 = 84^2 + a^2 \][/tex]
[tex]\[ 7225 = 7056 + a^2 \][/tex]
Now, subtract 7056 from both sides:
[tex]\[ 169 = a^2 \][/tex]
To solve for a, take the square root of both sides:
[tex]\[ a = \sqrt{169} \][/tex]
a = 13
So, the missing side length ( a ) is 13.
Therefore, the correct answer is option D: 13.

A regular hexagon and a regular octagon are joined as shown on the diagram.
Work out the size of angle x.
The interior angle of a regular hexagon is 120°. As two hexagons share a side, [tex]\( x \)[/tex] equals 120°.
In the given diagram, two regular hexagons share a common side, and an interior angle marked as [tex]\( x \)[/tex] is formed by the sum of the interior angles of the two hexagons. The interior angle of a regular hexagon is [tex]\( \frac{{180^\circ \times (n-2)}}{n} \)[/tex], where [tex]\( n \)[/tex] is the number of sides. For a hexagon [tex](\( n = 6 \))[/tex], this angle is [tex]\( \frac{{180^\circ \times (6-2)}}{6} = 120^\circ \)[/tex].
Considering the interior angles of both hexagons and the angle [tex]\( x \)[/tex], the equation [tex]\( 120^\circ + 120^\circ + x = 360^\circ \)[/tex] arises, as the sum of angles around a point is 360°. Solving for [tex]\( x \) yields \( x = 120^\circ \).[/tex] Therefore, the measure of angle [tex]\( x \)[/tex] in the diagram is 120°.
This solution demonstrates the application of the interior angle formula for a regular hexagon and the consideration of the total angle around a point, resulting in the determination that [tex]\( x \) is indeed \( 120^\circ \).[/tex]

Carrie gave her hair stylist a $4.20 tip. The tip was 15% of the cost of the
haircut. What is the total cost of the haircut?
The total cost of her haircut was 28 dollars
step by step:
(percentage) 15 x 6 = 90
4.20 x 6 =25.2
(perscentage) 15 divided by 3 = 5
4.20 divided by 3 = 1.4
1.4 + 1.4 = 2.8
25.2 + 2.8 =28
Final answer:
The total cost of the haircut before adding the tip was $28.00, found by setting up an equation where 15% of the total cost is equal to the $4.20 tip and solving for the total cost.
Explanation:
To calculate the total cost of the haircut that resulted in a $4.20 tip given at the rate of 15%, we need to set up a proportion where 15% of the total cost equals $4.20.
Step 1: Represent the unknown total cost of the haircut by the variable x.
Step 2: Set up the equation representing the tip as 15% of the total cost (0.15x = $4.20).
Step 3: Solve for x by dividing $4.20 by 0.15.
x = $4.20 / 0.15
x = $28.00
Therefore, the total cost of the haircut before adding the tip was $28.00.

The diameter of a semicircle is 2 yards. What is the semicircle's perimeter?
Use 3.14 for pie
The perimeter of a semicircle with a diameter of 2 yards is 5.14 yards when using 3.14 for pi.
Explanation:To calculate the perimeter of a semicircle with a diameter of 2 yards, we first need to find the radius, which is half of the diameter. Therefore, the radius (r) is 1 yard. Using the value of pi (π) as 3.14, the formula for the perimeter (P) of a semicircle is P = πr + 2r, where πr is the length of the semicircle's curved edge and 2r is the length of the diameter.
Plugging the radius into the formula, we get P = 3.14 × 1 yard + 2 × 1 yard. Simplifying this, we find P = 3.14 yards + 2 yards, which equals to 5.14 yards. Therefore, the perimeter of the semicircle is 5.14 yards.
Final answer:
The perimeter of a semicircle with a diameter of 2 yards is 5.14 yards, calculated by taking half the circumference of a full circle and adding the diameter.
Explanation:
To calculate the perimeter of a semicircle with a given diameter of 2 yards, we need to consider both the straight edge of the diameter and the curved edge of the semicircle.
The formula for the perimeter (P) of a full circle is P = πd, where π (pi) is approximately 3.14 and d is the diameter. Since we have a semicircle, we will take half of the circumference of the full circle and then add the diameter. So, the formula for the perimeter of the semicircle (P_semicircle) will be:
P_semicircle = (πd)/2 + d.
Let's plug in the values:
P_semicircle = (3.14 × 2 yards)/2 + 2 yards
P_semicircle = 3.14 yards + 2 yards
P_semicircle = 5.14 yards.
The perimeter of the semicircle is 5.14 yards.

A square pyramid. The square base has side lengths of 6 inches. The 4 triangular sides have a base of 6 inches and height of 9 inches.
Complete the sentences.
The area of the pyramid’s base is in.2.
The pyramid has lateral faces.
The surface area of each lateral face is in.2.
The total surface area is 144 in.2.
Answer:
The area of the pyramid’s base is 36 in².
The pyramid has 4 lateral faces.
The surface area of each lateral face is 27 in².
Step-by-step explanation:
"Lateral" means side, so the lateral faces are triangles.
The base is the bottom, which is a square.
To calculate the area of the base, use the formula for area of a square.
[tex]A_{base} = s^{2}[/tex]
[tex]A_{base} = (6 in)^{2}[/tex]
[tex]A_{base} = 36 in^{2}[/tex]
To calculate the area of a lateral face, find the area of a triangle.
[tex]A_{lateral} = \frac{bh}{2}[/tex]
[tex]A_{lateral} = \frac{(6 in)(9 in)}{2}[/tex]
[tex]A_{lateral} = \frac{54 in^{2}}{2}[/tex]
[tex]A_{lateral} = 27 in^{2}[/tex]
In a pyramid, the number of lateral faces is the same as the number of sides in the base. The square base as 4 sides, so there are 4 lateral faces.
The area of the pyramid's base is 36 square inches. The pyramid has 4 lateral faces, each with a surface area of 27 square inches. The total surface area is 144 square inches.
Area of the Base :
The base of the pyramid is a square with side lengths of 6 inches. To find the area of the square base:Area = side × side = 6 inches × 6 inches = 36 square inchesLateral Faces :
The pyramid has 4 triangular lateral faces.Surface Area of Each Lateral Face :
The base of each triangular face is 6 inches, and the height is 9 inches. To find the area of one triangular face, use the formula:Area = 1/2 × base × height = 1/2 × 6 inches × 9 inches = 27 square inchesTotal Surface Area :
The total surface area of the pyramid is the sum of the area of the base and the areas of the 4 triangular faces:Total Surface Area = Area of the base + 4 × Area of each triangular faceTotal Surface Area = 36 square inches + 4 × 27 square inches = 36 square inches + 108 square inches = 144 square inchesTherefore, area of the pyramid's base is 36 square inches, the pyramid has 4 lateral faces, each with a surface area of 27 square inches and the total surface area is 144 square inches.

10. The dot plot shows how many games
10 members played last month.
True or false?
a) The mode is 5 games
b) The median is 5 games
Answer:
A : False
B : False
Step-by-step explanation:
A : The mode of a data set is whichever number comes up the most.
8 comes up the most times, so 8 is the mode.
B : The median is a number which is in the middle of a data set
This is the data set as a list of numbers :
2, 5, 5, 5, 6, 6, 8, 8, 8, 8
the two sixes are in the middle, if there are 2 numbers in the middle, add them together and divide by two,
6 + 6 = 12
12 / 2 = 6
6 is the median.
Final answer:
The question relates to data analysis in Mathematics, focusing on the mode and median within a data set, which cannot be determined without the provided figures. The median is the middle value in an ordered data set, while the mode is the most frequent value.
Explanation:
The subject of this question is Mathematics, specifically focusing on concepts related to data analysis such as mode, median, and box plots. Without the actual dot plot or box plot figures provided, we cannot verify the true or false nature of the statements provided. However, generally, the mode is the number that occurs most frequently in a data set, and the median is the middle number when the data set is ordered from least to greatest. To construct a box plot for a given data set, you would need to calculate the minimum, first quartile, median, third quartile, and maximum of the data. These five statistics are then used to create the box plot, which provides a visual representation of the data distribution.
When discussing the median in a box plot, it is the value that divides the data set into two equal halves. The mode in contrast, may or may not correspond to any of the box plot’s five statistical summaries; it entirely depends on the frequency of the individual values.

Answer : no solution
Step-by-step explanation:
The system of the equations have infinitely many solutions.
What is the solution of the equation?The solution of the equation means the value of the unknown or variable.
The linear equation of two variable is given below.
6x + 3y = –12
6x + 3y + 12 = 0 ...1
–2x + 4 = y
2x + y – 4 = 0 …2
The standard equations are given as
a₁x + b₁y + c₁ = 0
a₂x + b₂y + c₂ = 0
Compare equation 1 and 2 with the standard equation. Then we have
a₁ = 6, b₁ = 3, c₁ = 12
a₂ = 2, b₂ = 1, c₂ = –4
If the ratio of the coefficient of x and y are different, then unique solution.
If the ratio of the coefficient of x and y are same, but constant term ratio is different, then no solution.
If the ratio of the coefficient of x and y and constant term is same, then infinitely many solutions.
a₁ / a₂ = 6/2 = 3
b₁ / b₂ = 3/1= 3
c₁ / c₂ = 12/(-4) = -3
Then the condition will be
a₁ / a₂ = b₁ / b₂ ≠ c₁ / c₂
