Answer:

She makes $60 per hour

Step-by-step explanation:

There are 5 days in a week and 40 divided by 5 is 8 and 8x10=80 and 80 subtracted by 20 gives you 60.

Final answer:

After deducting childcare expenses, Sally's actual hourly wage is $7.50 per hour.

Explanation:

The original question is about calculating Sally's actual hourly wage after accounting for childcare expenses. Sally works 40 hours a week and earns $10 per hour. However, she incurs a cost of $20 per day for childcare. Assuming she works 5 days a week, her weekly childcare expenses are $20 x 5 = $100. Therefore, her weekly take-home pay after childcare is (40 hours x $10/hour) - $100 = $400 - $100 = $300. Now, to find Sally's actual hourly wage after childcare expenses, divide her take-home pay by the number of hours worked: $300 / 40 hours = $7.50 per hour.

Answer:

Step-by-step explanation:

The salesman's commission for selling a car at Sal's car shop is $901.50.

To calculate the salesman's commission for selling a car at Sal's car shop, we must first determine the sale price's profit margin over the dealership's purchase price. The profit is found by subtracting the purchase price ($16,235) from the selling price ($22,245).

Profit = Selling Price - Purchase Price
Profit = $22,245 - $16,235
Profit = $6,010

Next, we calculate the commission by taking 15% of the profit:

Commission = Profit * Commission Rate
Commission = $6,010 * 0.15
Commission = $901.50

Therefore, the salesman's commission for selling the car is $901.50.

The sale price of the top after the 50% off discount is $8.44.

To calculate the sale price of the top with a 50% discount, follow these steps:

Step 1: Find the discount amount. The discount amount is 50% of the original price. To calculate this, multiply the original price by 0.50 (50% as a decimal):

Discount amount = 16.88 * 0.50 = 8.44

Step 2: Subtract the discount amount from the original price to find the sale price:

Sale price = Original price - Discount amount

Sale price = 16.88 - 8.44 = 8.44

When the customer applies the 50% off discount, they will pay $8.44 for the top, which is half of the original price of $16.88. This means they are getting a 50% discount on the original price.

[tex]\bf \cfrac{cot(A)}{tan(A)}\implies \cfrac{~~\frac{1}{tan(A)}~~}{tan(A)}\implies \cfrac{~~\frac{1}{tan(A)}~~}{\frac{tan(A)}{1}}\implies \cfrac{1}{tan(A)}\cdot \cfrac{1}{tan(A)} \\\\\\ \cfrac{1}{[tan(A)]^2}\implies \cfrac{1}{tan^2(A)}\implies \cfrac{1^2}{tan^2(A)}\implies \left( \cfrac{1}{tan(A)} \right)^2\implies cot^2(A)[/tex]

Final answer:

To simplify cotA/tanA, we recognize that cotA is the reciprocal of tanA. The expression simplifies to cosA^2/sinA^2, which can also be written as cotA^2.

Explanation:

To simplify the expression cotA/tanA, we can use the fundamental trigonometric identities that relate the cotangent and tangent functions. The cotangent function, cotA, is the reciprocal of the tangent function, tanA, which means cotA = 1/tanA. Therefore, when we simplify cotA/tanA, we are effectively dividing the reciprocal of the tangent function by the tangent function itself.

The simplification would thus be:

Answer:

There are 38 vocab. words in both weeks

Step-by-step explanation:

There are a few steps to this problem:

First, we know that there are 15 vocab. words in week 1.

Then, in week 2 there are 8 more words than in week 1. So that means 15+8 which equals 23.

Finally, we know that there were 15 words in the first week, and 23 in the second week. So now how many words were there in both weeks? To answer that, you add the number of words in the first week, to the number of words to the second week.

23 + 15 = 38 words total in both weeks

Answer:

106

Step-by-step explanation:

Given:

Thirteen fewer than three times his thinking number is 305.

Question asked:

What number is Tomás thinking ?

Solution:

Let Toma's thinking number be [tex]x[/tex]

As 13 fewer than 3 times his thinking number is 305.

The equation will be:

[tex](3 times of x) - 13 = 305[/tex]

[tex]3x - 13 = 305[/tex]

Adding both side by 13

[tex]3x = 318\\[/tex]

Dividing both side by 3

[tex]x = 106[/tex]

Thus,  Tomàs was thinking of a number is 106

a. The inequality that models the possible change in the number of feet, r, of the whale's elevation is: 35 - r ≤ 17.

This inequality represents the starting depth of 35 feet below the surface (35), minus the possible change in elevation (r), which should be less than or equal to the maximum height the whale jumps, which is nearly 17 feet above the surface (17).

b. By solving the inequality 35 - r ≤ 17, we can find the range of possible values for r.

First, subtract 35 from both sides of the inequality: -r ≤ 17 - 35. Simplifying further, we have -r ≤ -18. Then, multiply both sides by -1, remembering to reverse the inequality direction: r ≥ 18.

The solution to the inequality is r ≥ 18, meaning that the possible change in the number of feet of the whale's elevation must be equal to or greater than 18. This implies that the whale's jump cannot be less than 18 feet above the surface.

Therefore, the whale's elevation can change by any value equal to or greater than 18 feet, allowing it to jump to a height of nearly 17 feet above the surface.

a) The inequality can be written as 35 - r ≤ 17. b) The solution to the inequality is r ≥ 18, which means that the change in the number of feet, r, of the whale's elevation must be greater than or equal to 18.

a.

Since the whale swims upward and jumps to a height of nearly 17 feet above the surface, we can represent the change in elevation as r.

The inequality can be written as:

35 - r ≤ 17

Here, 35 represents the starting depth below the surface, and 17 represents the height above the surface that the whale reaches.

By subtracting r from the starting depth, we account for the possible decrease in elevation as the whale swims upward.

b. To solve the inequality, we can isolate r on one side of the equation:

35 - r ≤ 17

Adding r to both sides of the inequality:

35 - r + r ≤ 17 + r

35 ≤ 17 + r

Subtracting 17 from both sides:

35 - 17 ≤ 17 + r - 17

Simplifying further:

18 ≤ r

Therefore, the solution to the inequality is r ≥ 18.

In terms of the situation, the inequality r ≥ 18 means that the change in the number of feet, r, of the whale's elevation must be greater than or equal to 18.

This indicates that as the whale swims upward and jumps to a height of nearly 17 feet above the surface, the whale's elevation can increase by at least 18 feet from its starting depth of 35 feet below the surface.

We want to complete the statement:

The _______ represents the number of standard deviations an observation is from the mean.

Whenever we calculate z- scores, we are finding how many standard deviations an observation is from the mean.

A z-score of 3, means an observation is 3 standard deviation above the mean.

Therefore the best complete is:

z-score.

The Z-score represents the number of standard deviations an observation is from the mean. It provides a comparative measure that standardizes data, making it easier to compare data from different sets.

The Z-score represents the number of standard deviations an observation is from the mean. In statistics, it is a way to compare the position of any observation relative to the overall distribution.

Here's an example: if a Z-score of a data point is 2, it means that the data point is 2 standard deviations above the mean. Conversely, if a Z-score of a data point is -1, it means that the data point is 1 standard deviation below the mean.

Z-scores provide a standardized way to interpret data, which makes the comparison of different data sets more straightforward and undistorted by differences in units or scales.

Step-by-step explanation:

Hope this helps you and anyone looking for an answer to their headache.

Final answer:

The reflected coordinates of the rectangle over the y-axis are L'(-1, -1), M'(-1, -9), N'(-8, -9), and O'(-8, -1), matching option 1.

Explanation:

The student is asking about finding the coordinates of a rectangle's vertices after it has been reflected over the y-axis. Reflecting a shape over the y-axis changes the sign of the x-coordinate of each vertex, while the y-coordinate remains the same. So, if we have a point (x, y), the reflected point over the y-axis would be (-x, y). Applying this to the rectangle's vertices we have:

For L(1, -1), the reflection L' would be (-1, -1).

For M(1, -9), the reflection M' would be (-1, -9).

For N(8, -9), the reflection N' would be (-8, -9).

For O(8, -1), the reflection O' would be (-8, -1).

Therefore, the correct reflected coordinates are L'(-1, -1), M'(-1, -9), N'(-8, -9), and O'(-8, -1), which corresponds to option 1.
