Billy has $80 to spend. He spent $54.50 on Bruno Mars Tickets. If Stickers cost $1.34 each, what is the maximum number of Stickers he can buy? Define a variable then write and solve an inequality. Write your answer using a complete sentence.
Answers
Answer:
Billy can buy 19 or less than 19 stickers.
Step-by-step explanation:
Solving inequality:Let the unknown variable - number of stickers be 'x'.
Cost of one sticker = $1.34
Cost of 'x' stickers = 1.34 * x = 1.34x
Maximum amount that can be spent for buying stickers = 80 - 54.50
= $25.50
Inequality:
1.34x ≤ 25.50
Solving:
Divide both sides by 1.34,
[tex]\sf x \leq \dfrac{25.50}{1.34}[/tex]
x ≤ 19.03
x ≤ 19
Billy can buy 19 or less than 19 stickers.

The expression a⁻¹³/a⁻⁶ can be written as a⁻⁷ in aⁿ form.
We have been given the expression
a⁻¹³/a⁻⁶
We know that whenever there is a minus sign in the power, we need to consider a reciprocal of the number
Hence,
a⁻¹³ will become 1/a¹ and a⁻⁶ will become 1/a⁶
Hence the numerator and denominator will interchange to get
a⁶/a¹³
Now, we know that when a number is broght from denominator to the numerator, there is a minus sign added to the power. Hence we will get
a⁶ X a⁻¹³
Since the two numbers have the same base- a, we can add the powers up as there is multiplication sign in between to get
a⁶ ⁺ ⁽⁻¹³⁾
= a⁶ ⁻ ¹³
= a⁻⁷
Hence, the expression a⁻¹³/a⁻⁶ can be written as a⁻⁷ in aⁿ form.

How can the magnitude of an earthquake be calculated when its intensity is 10,000 times that of the reference earthquake?
The correct equation that calculates the magnitude, M, of an earthquake with an intensity 10,000 times that of the reference earthquake is option B: M = log(10,000/Io).
In the given equation M = log(I/IO), I represents the intensity of the earthquake being measured, and IO represents the intensity of the reference earthquake. Since the intensity of the earthquake in question is 10,000 times that of the reference earthquake, we substitute I with 10,000 times IO.
Therefore, the equation becomes M = log(10,000/Io), which is option B. This equation allows us to calculate the magnitude of the earthquake based on the relative intensity compared to the reference earthquake.

Given cos(θ) = 5/9, you want the six trig functions of θ.
IdentitiesThe relevant identities are ...
sin(θ) = ±√(1 -cos(θ)²)tan(θ) = sin(θ)/cos(θ)csc(θ) = 1/sin(θ)sec(θ) = 1/cos(θ)cot(θ) = 1/tan(θ)SineThe sine of θ is ...
sin(θ) = √(1 -(5/9)²) = √(81 -25)/9 = (√56)/9
sin(θ) = (2/9)√14
Then the cosecant is ...
csc(θ) = 1/sin(θ) = (9/2)/√14
csc(θ) = (9√14)/28
TangentThe tangent of θ is ...
tan(θ) = sin(θ)/cos(θ) = ((2/9)√14)/(5/9)
tan(θ) = (2/5)√14
Then the cotangent is ...
cot(θ) = 1/tan(θ) = (5/2)/√14
cot(θ) = (5√14)/28
SecantThe secant of θ is ...
sec(θ) = 1/cos(θ) = 1/(5/9)

T(0.66) = 2.3244°
T(0.88) = 4.8184°
T(1.1) = -4.1686 °
How did we get the above ?To solve the above, we need to use the formuala that we given which is T(x) = 5.8cos(3.8πx)
Entering the various values of x, can can obtain
T(0) = 5.8 cos (3.8π (0) ) = 5.8cos(0) = 5.800

Answers
The area of the shaded region is 422.8 m², rounded to the nearest tenth.
To find the area of the shaded region, we first need to determine the areas of the two shapes that make up the region. The first shape is a rectangle with dimensions of 18.6 m by 30 m, which has an area of:
Area of rectangle = length x width = 18.6 m x 30 m = 558 m²
The second shape is a semi-circle with a diameter of 18.6 m, which has a radius of 9.3 m. The area of a semi-circle is half the area of a full circle, so we can use the formula for the area of a circle to find the area of the semi-circle:
Area of semi-circle = (1/2) x π x r² = (1/2) x π x 9.3² = 135.2 m²
To find the area of the shaded region, we need to subtract the area of the semi-circle from the area of the rectangle:
Area of shaded region = Area of rectangle - Area of semi-circle
Area of shaded region = 558 m² - 135.2 m²

Square $ABCD$ has side length 7. What is the length of the diagonal $AC?$ (its a square also)
Answers
The length of the diagonal AC in square ABCD is approximately 9.899 units.
To find the length of the diagonal AC, we can use the Pythagorean theorem, which states that in a right-angled 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.
In our case, since ABCD is a square, angle ABC is a right angle. Therefore, triangle ABC is a right-angled triangle with sides AB and BC both equal to 7 units. We can apply the Pythagorean theorem to find the length of diagonal AC (the hypotenuse):
AC² = AB² + BC²
Plugging in the side lengths:
AC² = 7² + 7² = 49 + 49 = 98
Now, we take the square root of both sides to find the length of AC:
AC = √98 ≈ 9.899
So, the length of the diagonal AC in square ABCD is approximately 9.899 units.

Answers
The volume of the large box is 200 cubic inches. The volume of the small box is 150 cubic inches. The difference in the volumes of the two boxes is 50 cubic inches. The units that should be used for each of these answers is cubic inches.
To find the volume of each box, we'll use the formula for the volume of a rectangular prism: Volume = Length × Width × Height.
For the larger box, the dimensions are:
Length = 8 inches
Width = 2.5 inches
Height = 10 inches
Volume of large box = 8 × 2.5 × 10 = 200 cubic inches
For the smaller box, its length is 75% of the larger box's length:
Length = 0.75 × 8 = 6 inches
The width and height remain the same, so the dimensions are:
Length = 6 inches
Width = 2.5 inches
Height = 10 inches
Volume of small box = 6 × 2.5 × 10 = 150 cubic inches
The difference in the volumes of the two boxes is:
200 cubic inches - 150 cubic inches = 50 cubic inches
So, the difference in the volumes of the two boxes is 50 cubic inches. The units used for these answers are cubic inches.

Answers
The pool has approximately 258.2 square feet of plastic material. Rounded to the nearest tenth, the answer is 258.2 square feet.+
To calculate the surface area of the pool that is lined with plastic material, we need to find the area of the curved part and the area of the top and bottom circles.
First, let's find the radius of the pool, which is half of the diameter:
radius = 11 feet / 2 = 5.5 feet
The curved part of the pool is a cylinder with a height of 2 feet and a circumference of [tex]2 * π *radius:[/tex]
curved area = height * circumference
[tex]curved area = 2 feet * 2 * 3.14 * 5.5 feet[/tex]
[tex]curved area = 68.2 square feet[/tex]
The top and bottom of the pool are two circles with a radius of 5.5 feet:
circle area = π * radius²
[tex]circle area = 3.14 * 5.5 square feet[/tex]
[tex]circle area = 95.0 square feet[/tex]
To find the total surface area of the pool that is lined with plastic material, we add the area of the curved part and the area of the top and bottom circles:
Total area = curved area + 2 * circle area
Total area = 68.2 square feet + 2 * 95.0 square feet
Total area = 258.2 square feet

We can use the given point P(3, 4) to find the values of sin(theta) and cos(theta) as follows:
[tex]sin(theta) = opposite/hypotenuse = 4/5[/tex]
[tex]cos(theta) = adjacent/hypotenuse = 3/5[/tex]
Since theta is a first-quadrant angle, we know that tan(theta) = sin(theta)/cos(theta).
Using the half-angle formula for tangent, we have:
[tex]tan(1/2 * theta) = ±√((1 - cos(theta))/2) / (1 + √((1 - cos(theta))/2))[/tex]
We can substitute the values of sin(theta) and cos(theta) that we found earlier:
[tex]tan(1/2 * theta) = ±√((1 - 3/5)/2) / (1 + √((1 - 3/5)/2))[/tex]
[tex]tan(1/2 * theta) = ±√(1/5) / (1 + √(1/5))[/tex]
[tex]tan(1/2 * theta) = ±√5 - 1[/tex]
Since theta is in the first quadrant, tan(1/2 * theta) is positive. Therefore:
[tex]tan(1/2 * theta) = √5 - 1[/tex]
We can simplify this expression by rationalizing the denominator:
[tex]tan(1/2 * theta) = (√5 - 1) / (√5 + 1) * (√5 - 1) / (√5 - 1)[/tex]
[tex]tan(1/2 * theta) = (5 - 2√5)[/tex]

If Susan stands 300 m away from the lighthouse and looks up at it with an angle of elevation of 5 degrees, the height of the lighthouse is approximately 26 meters. This calculation is important for navigation and other purposes.
To determine the height of the lighthouse, we can use trigonometry. We know that the angle of elevation, which is the angle between Susan's line of sight and the ground, is 5'. We also know the distance between Susan and the lighthouse, which is 300 m.
We can use the tangent function to find the height of the lighthouse:
tan(5') = height/300
To solve for height, we can cross-multiply and simplify:
height = 300 x tan(5')

The two numbers are 129 and 62, which satisfy the given conditions: their sum is 191 and their difference is 67 .
You are asked to find two numbers whose sum is 191 and whose difference is 67. Let's use the variables x and y to represent these two numbers.
We can establish the following two equations under the given conditions: 1) x + y = 191 2) x - y = 67
Now we can solve this system of linear equations to find the values of x and y.
We can start by adding both equations:

Alec bought a house. By the end of the first year, the value of Alec's house had increased by 1%. By the end of the second year, its value had decreased by 10% of its value at the end of the first year. Use multipliers to work out the overall percentage decrease in the value of Alec's house for this two-year period
Answers
The overall percentage decrease in the value of Alec's house for the two-year period is 9.9%.
Let's assume the original value of Alec's house as $100. After the first year, the value of the house increased by 1%, which means the new value of the house is $101.
Now, in the second year, the value of the house decreased by 10% of its value at the end of the first year. Therefore, the new value of the house at the end of the second year can be calculated as $101 - (10/100)*$101 = $90.90.
To find the overall percentage decrease in the value of Alec's house for the two-year period, we can use the formula:
Overall percentage decrease = [(Original value - Final value)/Original value] * 100%
Substituting the values, we get,
Overall percentage decrease = [($100 - $90.90)/$100] * 100% = 9.9%
Therefore, the overall percentage decrease in the value of Alec's house for the two-year period is 9.9%.

Josh wants to simplify the expression (-8)(10+(-5)+(-8))
Answers
Therefore, the simplified expression is 24.
To simplify the expression (-8)(10+(-5)+(-8)), you first need to solve the parentheses, following the order of operations, which requires solving the addition and subtraction within the parentheses before multiplying.
So, you have (-8)(10-5-8), which becomes (-8)(-3) after solving the parentheses. Finally, you can solve the multiplication by multiplying -8 by -3, resulting in 24.
It's important to remember the order of operations when simplifying expressions, which is Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

A person stands on level ground 60 m from the nearest point of a cylindrical tank of radius length 20 m. Calculate:
a- the circumference of the tank
b the percentage of the circumference that is visible to the person
Answers
The circumference of the tank is is 125.66m and the percentage of the circumference that is visible to the person is 10.24%.
a) To calculate the circumference of the cylindrical tank, using the formula C = 2πr, where C is the circumference and r is the radius of the tank. In this case, r = 20 m, so:
C = 2π(20 m) ≈ 125.66 m
b) To determine the percentage of the circumference visible to the person, we first need to calculate the angle (in degrees) that subtends the visible arc. This can be done using the inverse tangent function:
angle = atan(opposite/adjacent) = atan(20 m/60 m)
angle ≈ 18.43°
Since the visible arc is symmetrical on both sides, the total angle of the visible arc is twice the calculated angle:
total angle ≈ 36.86°
Now, calculate the percentage of the circumference that is visible by dividing the total angle by 360° and multiplying by 100%:
percentage = (36.86°/360°) × 100% ≈ 10.24%
So, the visible percentage of the circumference to the person is approximately 10.24%.
