The prefix (deci-, centi-, or deca-) tells you to multiply by 0.1. Which one is it?
The cost C (in dollars) for the care and maintenance of a horse and carriage is C=15x+2000 where x is the number of rides.
Rides cost 35$
A: write an equation for the revenue R in terms of the number of rides
B: How many rides are needed to break even.
Need help with both parts
Answer: 100 rides are needed to break even.
Step-by-step explanation:
We have given the cost function
C(x)=15x+2000 where x is the number of rides.
And rides cost 35$
⇒ revenue function would be 35 times x
i.e.R(x)=35 x , where x is the number of rides.
Break even point of a firm occurs when at a certain point x the total cost equals to the total revenue.
i.e. at break even point
total revenue=total cost
⇒35x=15x+2000
⇒35-15x=2000[subtract 15x from both sides]
⇒20x=2000 [simplify]
⇒x=2000/20[dividing both sides with 20]
⇒x=100
∴ 100 rides are needed to break even.
The revenue function will be 35x and the breakeven point will be 100 rides.
From the information given, the revenue function will be calculated by multiplying the price by the quantity. This will be:
= 35 × x
= 35x
The breakeven point will be the point where total revenue equals the total cost. This will be:
35x = 15x + 2000
35x - 15x = 2000
20x = 2000
x = 2000/20
x = 100
Therefore, the revenue function will be 35x and the breakeven point will be 100 rides.

Which statement is not true about similar triangles? Corresponding angles are equal. Each triangle has 3 sides. The lengths of corresponding sides are proportional Corresponding sides are congruent.
Corresponding sides are congruent is not the correct answer here.
What is a similar and congruent triangle ?Similar triangles has same corresponding angles and the corresponding sides are in proportion and for the congruent triangles the corresponding angles and the corresponding sides are same.
Two triangles is similar if their corresponding angles are congruent and their corresponding sides are in equal proportion.
We can can think of a triangle having x°, y°, z° as it's interior angle and for the other triangle to be similar it must also have x°, y°, z° as it's interior angle and the first triangle has length of the 3 sides equal to some values the other triangle to be similar it's side must have values in the same multiples of the previous values of the first triangle.

To evaluate (rs)(4) and (r/s)(3) for the given functions, substitute the value of x into the functions and calculate the product and quotient, respectively.
Explanation:To find (rs)(4), we need to substitute the value of x into the functions r(x) and s(x) and then find their product. r(x) = 2√x, so r(4) = 2√4 = 2√2 = 2(2) = 4. s(x) = √x, so s(4) = √4 = 2. Therefore, (rs)(4) = 4(2) = 8.
To find (r/s)(3), we need to substitute the value of x into the functions r(x) and s(x) and then find their quotient. r(3) = 2√3 and s(3) = √3. Therefore, (r/s)(3) = (2√3) / √3 = 2.

Solve the equation on the interval 0 ≤ θ < 2π.
1 - sin θ = 1/2
Final answer:
To solve the equation 1 - sin θ = 1/2 on the interval 0 ≤ θ < 2π, isolate the sine function and find the values of θ that satisfy the equation by taking the inverse sine of both sides. The solutions are θ = -π/6 and θ = 5π/6.
Explanation:
To solve the equation 1 - sin θ = 1/2 on the interval 0 ≤ θ < 2π, we can start by isolating the sine function. Subtracting 1/2 from both sides of the equation, we get -sin θ = -1/2. Next, we can find the values of θ that satisfy this equation on the given interval by taking the inverse sine (sin⁻¹) of both sides. This gives us θ = sin⁻¹(-1/2).
Using the unit circle or a calculator, we can find the values of θ that satisfy this equation. Let's first find the value of θ in the first quadrant. Here, sin θ = -1/2, so θ = sin⁻¹(-1/2) = -π/6.
Since we are looking for solutions on the interval 0 ≤ θ < 2π, we need to find the other solution that lies in the second quadrant. In the second quadrant, sin θ is also negative, but the angle is measured from the positive x-axis in the clockwise direction. Therefore, θ = -π + π/6 = 5π/6 is the other solution.
Final answer:
To solve the equation 1 - sin θ = 1/2 on the interval 0 ≤ θ < 2π, you can isolate the sine function and apply the inverse sine function to find the solutions.
Explanation:
To solve the equation 1 - sin θ = 1/2 on the interval 0 ≤ θ < 2π, we can start by isolating the sine function. Subtracting 1/2 from both sides of the equation, we get -sin θ = -1/2.
Next, we can apply the inverse sine function to both sides. This will give us two possible values for θ within the given interval: θ = π/6 and θ = 5π/6.
Therefore, the solutions to the equation 1 - sin θ = 1/2 on the interval 0 ≤ θ < 2π are θ = π/6 and θ = 5π/6.
Which word sentence represents the equation?
6(x + 3) = 42
A. The sum of 3 and six times some number is 42.
B. Three plus 3 times some number is 42.
C. Six times some number plus 3 is 42.
D. Six times the sum of a number and 3 is 42.
The word sentence that represents the equation 6(x + 3) = 42 is option A: The sum of 3 and six times some number is 42.
Explanation:The word sentence that represents the equation 6(x + 3) = 42 is option A. The sum of 3 and six times some number is 42.
To understand why, let's break down the equation step-by-step:
We have the expression (x + 3) in parentheses, which means that whatever number the student chooses to replace x with should be added to 3.Next, we multiply the entire expression (x + 3) by 6.The result of that multiplication should equal 42.So, option A correctly expresses the equation by stating that the sum of 3 and six times some number is 42.
