Final answer:
The baker's revenue R can be expressed as R = x * 6.50, and the cost C can be expressed as C = 45 + 25 + (x * 1.75). To find the number of cakes he needs to sell before making a profit, we set the revenue equal to the cost and solve for x. The baker will need to sell at least 15 cakes before making a profit.
Explanation:
To express the revenue R as a function of x, we can use the equation R = x * 6.50. This is because the revenue is the number of cakes sold multiplied by the price per cake. So, every cake sold contributes $6.50 to the revenue.
To express the cost C as a function of x, we can use the equation C = 45 + 25 + (x * 1.75). The initial fixed costs of $45 for reserving a booth and $25 for traveling expenses are added to the variable costs of $1.75 per cake multiplied by the number of cakes sold.
To find the number of cakes he needs to sell before making a profit, we need to set the revenue equal to the cost and solve for x:
R = C => x * 6.50 = 45 + 25 + (x * 1.75)
Combining like terms, we get:
4.75x = 70
x = 70 / 4.75
x ≈ 14.74
Since you cannot sell a fraction of a cake, the baker will need to sell at least 15 cakes before making a profit.

A superhero recently asked his nemesis how many cats she has. She answered with a riddle: "Seven-eighths of my cats plus five." How many cats does the nemesis have?
The question presents a riddle that can be solved by setting up and solving an algebra equation. Based on the provided information, the solution to the problem is that the nemesis has 40 cats.
Explanation:The problem describes a riddle: "Seven-eighths of my cats plus five." This scenario is a typical mathematical representation of an algebra problem where you need to find the total number of cats.
Let us denote the total number of cats as 'C'. According to the riddle, 7/8 of the cats plus 5 equals the total cats. As per this, the equation can be written as 7/8*C + 5 = C. Solving this will lead us to find the number of cats.
Subtract 7/8*C from both sides of the equation: 5 = C - 7/8*C, which simplifies into: 5 = 1/8*C. To solve for 'C', we then multiply both sides of the equation by 8: 5*8 = C. Hence, the nemesis has 40 cats.

The side lengths that model a rectangle with an area of x^2 + 3x – 10 are x + 5 and x – 2, obtained by factoring the quadratic expression.
Explanation:To find the side lengths of a rectangle that model an area of x2 + 3x – 10 square units, we need to factor this quadratic expression. Factoring involves finding two binomials that when multiplied together, give the original quadratic expression. The factors of -10 that add up to 3 (the coefficient of the middle term) are 5 and -2. Therefore, the factored form of x2 + 3x – 10 is (x + 5)(x – 2), meaning the side lengths that can be used to model this rectangle are x + 5 and x – 2.

Which value represents |7.8|?
The value of |7.8| is 7.8 because the absolute value of a number is the non-negative value of that number without regard to its sign.
The student has asked what the value of |7.8| is. The absolute value, denoted by the vertical bars, refers to the distance of a number from zero on the number line without considering direction. Therefore, the absolute value of 7.8 is 7.8 itself, regardless of any negative sign. It's because the absolute value of a positive number is the number itself, and the absolute value of a negative number is the positive version of that number.

A. 1/13 +8/13i
B. -1/13+8/13i
C. 1/13-8/13i
D. -1/13-8/13i
Final answer:
The division of the complex numbers (3 - i) by (1 + 5i) results in the standard form -1/13 - 8/13i, by multiplying both the numerator and denominator by the conjugate of the denominator. The correct answer is option D.
Explanation:
To divide the complex number 3 - i by 1 + 5i, we should multiply numerator and denominator by the conjugate of the denominator to get rid of the imaginary part in the denominator:
Multiply both top and bottom by the conjugate of the denominator, which is 1 - 5i.(3 - i) * (1 - 5i) = 3 - 15i - i + 5i2
Since i2 = -1, it simplifies to:
3 - 16i - 5 = -2 - 16i
(1 + 5i) * (1 - 5i) = 1 - 5i + 5i - 25i2
Similarly, it simplifies to:
1 + 25 = 26
Divide the top result by the bottom result:(-2 - 16i) / 26 = -2/26 - 16i/26
Simplify the fractions:
-1/13 - 8/13i
The standard form of the result is -1/13 - 8/13i, which corresponds to option D.

Suppose the cpi was 110 last year and is 121 this year. instructions: in part a, enter your answer as a whole number. in part b, round your answer to 1 decimal place. if you are entering any negative numbers be sure to include a negative sign (-) in front of those numbers.
a. what is this year’s rate of inflation?
The rate of inflation from last year to this year is calculated by finding the 'change in CPI' which is then divided by the 'old CPI' and multiplied by 100 to convert it into percentage. The change in CPI is the new CPI minus the old CPI. By following the steps, we find that the rate of inflation is 10%.
Explanation:To calculate the rate of inflation, we first need to determine the 'change in CPI', which will then be divided by the 'old CPI'. The formula is:
(New CPI - Old CPI) / Old CPI x 100%
The 'change in CPI' is the new CPI (this year's CPI) minus the old CPI (last year's CPI). This will be:
121 (this year's CPI) - 110 (last year's CPI) = 11
Now, we'll divide 'change in CPI' by old CPI, which is:
11 (change in CPI) / 110 (old CPI) = 0.1
To convert the value into percentage, we should multiply it by 100:
0.1 x 100 = 10
So, this year's rate of inflation is 10%.

The planet Mars has two moons – Phobos and Deimos. Phobos has a mass of 10.8 × 1015 kilograms, and Deimos has a mass of 2.0 × 1015 kilograms. How much greater is the mass of Phobos than the mass of Deimos?
Answer:
mass of Phobos is 8.8 × 10¹⁵ Kilograms greater than mass of Deimos.
Step-by-step explanation:
The planet Mars has two moons Phobos and Deimos.
Mass of Phobos = 10.8 × 10¹⁵ Kilograms
Mass of Deimos = 2 × 10¹⁵ Kilograms
So the difference in the masses of the moons
= 10.8 × 10¹⁵ - 2 × 10¹⁵
= (10.8 - 2) × 10¹⁵
= 8.8 × 10¹⁵ Kilograms
Therefore, mass of Phobos is 8.8 × 10¹⁵ Kilograms greater than mass of Deimos.

The formula d = rt gives the distance traveled in time t at rate r. A bicyclist rides for 1.5 hours and travels 25 miles.
What was her average speed?
Answer:
16 2/3
Step-by-step explanation:
The bicyclist's average speed was 16.67 miles per hour
The student asks about the average speed of a bicyclist who traveled for 1.5 hours and covered 25 miles. The average speed can be found using the formula v = d/t, which suggests speed (v) equals distance (d) divided by time (t). To solve for the bicyclist's average speed, we'll insert the given values into the formula.
Here's the step-by-step calculation:
Identify the given variables: d = 25 miles and t = 1.5 hours.
Substitute the values into the formula: v = 25 miles / 1.5 hours.
Calculate the quotient to find the average speed: v = 16.67 miles per hour (rounded to two decimal places).
Therefore, to find the bicyclist's average speed, divide the distance traveled, 25 miles, by the time spent, 1.5 hours, which yields an average speed of 16.67 miles per hour.
which rate converts to a unit rate of 65 miles per hour

Final answer:
The Long family spent $38.62 for school supplies and $215.78 for new school clothes. To find the total amount spent, add the cost of school supplies and new school clothes. To calculate the sales tax, multiply the total amount spent by the sales tax rate.
Explanation:
To find the total amount spent, we need to add the cost of school supplies and new school clothes. The Long family spent $38.62 on school supplies and $215.78 on new school clothes, so the total amount spent is $38.62 + $215.78 = $254.40. Now, to calculate the sales tax, we need to find the percentage of the total amount spent. Let's assume the sales tax rate is 8%. To find the sales tax amount, we multiply the total amount spent by the sales tax rate as a decimal: $254.40 x 0.08 = $20.35.
