you just bought a new iphone for $999.the tax is 9% of the cost. how much did you pay in total with taxes?

Answer: The shirt's price after reduction = $ 84.15

Step-by-step explanation:

Given: Price of shirt= $ 85

Marked up percent = 10%

Reduced percent = 10%

Price after mark up = (Price of shirt) + 10% of (Price of shirt)

= $ (85+10% x 85)

= $ (85+(0.1) x (85))

= $ (85+8.5)

= $ 93.5

Price after 10% reduction = (Price after mark up)- 10% of (Price after mark up)

= $ (93.5-0.1 x 93.5)

= $ (93.5-9.35)

= $ 84.15

Hence, the shirt's price after reduction = $ 84.15

(D) "Your type of employment is dependent on things you can control" is a pro of being a wage earner.

This is a pro of being a wage earner because, although you may not have complete control over your job responsibilities, you do have control over your skills and qualifications that can help you secure and maintain employment.

Additionally, being a wage earner often provides stability and benefits such as health insurance and retirement plans.

However, it is important to note that there are also potential cons to being a wage earner such as limited upward mobility and the potential for layoffs or job insecurity.

Answer:

ok well whats the question?

Step-by-step explanation:

It will cost $312 to replace the glass in the window.

By multiplying the window's area by the tinted glass' price per square foot, we can figure out how much it will cost to replace the window's glass.

Looking at the plan, we can see that the window is in the shape of a rectangle. We need to find the length and width of the window to calculate its area.

Let's assume the length of the window is L feet and the width is W feet.

From the plan, we can see that the length of the window is 4 units and the width is 3 units.

Therefore, L = 4 feet and W = 3 feet.

The area of a rectangle is given by the formula: A = L * W

Substituting the values, we have: A = 4 feet * 3 feet = 12 square feet.

Now, we need to multiply the area of the window (12 square feet) by the cost per square foot of the tinted glass ($26 per square foot) to find the total cost.

Total cost = Area of window * Cost per square foot

Total cost = 12 square feet * $26 per square foot

Total cost = $312

Answer:

f(x) = x² - 10x, g(x) = x + 10

a) (f + g)(-3) = (-3)² - 10(-3) + (-3) + 10

= 9 + 30 - 3 + 10 = 46

b) (f - g)(-3) = (-3)² - 10(-3) - (-3 + 10)

= 9 + 30 - 7 = 32

c) (fg)(-3) = ((-3)² - 10(-3))(-3 + 10)

= (9 + 30)(7) = 39(7) = 273

d) (f/g)(-3) = ((-3)² - 10(-3))/(-3 + 10)

Answer:

13a + 9b + 5c + 2

Step-by-step explanation:

Combine like terms. Like terms are terms that have the same amount of the same variables. Reformat the given expression so that like expressions are next to each other:

16a - 3a + 9b + 5c + 2

Combine the like terms, 16a and -3a:

16a - 3a = 13a

13a + 9b + 5c + 2 would be your answer.

Note that none of the remaining terms share like terms. Note also that when a term does not have (a) variable(s) attached (such as the 2 in the end of the expression), it is known as a constant.

Answer:

13a + 9b + 5c + 2

Step-by-step explanation:

Given expression,

→ 16a - 3a + 2 + 9b + 5c

Main steps included in solving,

→ Rearranging the expression

→ Combining the like terms

Let's simplify the expression,

→ 16a - 3a + 2 + 9b + 5c

→ (16a - 3a) + (9b) + (5c) + 2

→ (13a) + 9b + 5c + 2

→ 13a + 9b + 5c + 2

Hence, this is the answer.

The class expects to raise $122 from selling 110 cupcakes and 150 cookies at the given prices.

It seems like there is some incomplete or unclear information in your statement. However, I can provide you with some interpretation based on the information provided.

If the eighth graders sell cupcakes at $0.70 apiece and cookies at $0.30 apiece, the total amount of money raised can be represented by the expression 0.7p + 0.3k, where p represents the number of cupcakes sold and k represents the number of cookies sold.

The class expects to sell 110 cupcakes and 150 cookies. Plugging these values into the expression, we can calculate the total amount raised:

Total amount raised = (0.7 * 110) + (0.3 * 150)

= 77 + 45

= $122

Therefore, the class expects to raise $122 from selling 110 cupcakes and 150 cookies at the given prices.

a) By strong induction, any amount of postage worth 8 cents or more can be made from 3-cent or 5-cent stamps.

b) By strong induction, any amount of postage worth 24 cents or more can be made from 7-cent or 5-cent stamps.

c) By strong induction, any amount of postage worth 12 cents or more can be made from 3-cent or 7-cent stamps.

a. Prove that any amount of postage worth 8 cents or more can be made from 3-cent or 5-cent stamps.

Base case: For postage worth 8 cents, we can use two 4-cent stamps, which can be made using a combination of one 3-cent stamp and one 5-cent stamp.

Induction hypothesis: Assume that any amount of postage worth k cents or less, where k is greater than or equal to 8, can be made from 3-cent or 5-cent stamps.

Induction step: Consider any amount of postage worth (k+1) cents. Since k is greater than or equal to 8, we can use the induction hypothesis to make k cents using 3-cent or 5-cent stamps. Then, we can add one more stamp to make (k+1) cents. If the last stamp we added was a 3-cent stamp, we can replace it with a 5-cent stamp to get the same value. If the last stamp we added was a 5-cent stamp, we can replace it with two 3-cent stamps to get the same value. Therefore, any amount of postage worth (k+1) cents can be made from 3-cent or 5-cent stamps.

b. Prove that any amount of postage worth 24 cents or more can be made from 7-cent or 5-cent stamps.

Base case: For postage worth 24 cents, we can use three 8-cent stamps, which can be made using a combination of one 7-cent stamp and one 5-cent stamp.

Induction hypothesis: Assume that any amount of postage worth k cents or less, where k is greater than or equal to 24, can be made from 7-cent or 5-cent stamps.

Induction step: Consider any amount of postage worth (k+1) cents. Since k is greater than or equal to 24, we can use the induction hypothesis to make k cents using 7-cent or 5-cent stamps. Then, we can add one more stamp to make (k+1) cents. If the last stamp we added was a 5-cent stamp, we can replace it with two 7-cent stamps to get the same value. If the last stamp we added was a 7-cent stamp, we can replace it with three 5-cent stamps to get the same value. Therefore, any amount of postage worth (k+1) cents can be made from 7-cent or 5-cent stamps.

c. Prove that any amount of postage worth 12 cents or more can be made from 3-cent or 7-cent stamps.

Base case: For postage worth 12 cents, we can use one 3-cent stamp and three 3-cent stamps, which can be made using a combination of two 7-cent stamps.

Induction hypothesis: Assume that any amount of postage worth k cents or less, where k is greater than or equal to 12, can be made from 3-cent or 7-cent stamps.

Induction step: Consider any amount of postage worth (k+1) cents. Since k is greater than or equal to 12, we can use the induction hypothesis to make k cents using 3-cent or 7-cent stamps. Then, we can add one more stamp to make (k+1) cents. If the last stamp we added was a 3-cent stamp, we can replace it with two 7-cent stamps to get the same value. If the last stamp we added was a 7-cent stamp, we can replace it with one 3-cent stamp and two 7-cent stamps to get the same value. Therefore, any amount of postage worth (k+1) cents can be made from 3

Step-by-step explanation:

Now assuming total donation needed to be in the silver category Is P

We can assume also the three additional and equal donations be Q

Then 50 + 3Q = P

So we still don't know P

We can get Q by saying

3Q= P - 50

Q = (P - 50) /3

Answer:

D

Step-by-step explanation:

Let's first write the possible function described.

The roots are:

-5 with a multiplicity of 3.

1 with a multiplicity of 2.

And 3 with a multiplicity of 7.

And the leading coefficient is negative.

Therefore:

\(f(x)=-a(x+5)^3(x-1)^2(x-3)^7\)

Where a is a positive value.

We want to know which statement is true about the graph.

First, since the second root is squared, it will always be positive. And since the leading coefficient is negative, our function is now negative.

So, we will only need to test the first and third root, as only they can alter the sign of our function.

Choice A)

(-∞, -5).

Pick any point within this interval. We can use -6 for simplicity. As stated previously, we only need to test the first and third root. We can ignore the exponents as well, since they do not alter signs. Therefore:

\((-6+5)(-6-3)=(-1)(-9)=9>0\)

Since the result is positive, and our function is already negative, our function is negative for (-∞, -5).

A is not correct.

Choice B)

(-5, 3)

Choosing 0:

\((0+5)(0-3)=-15<0\)

Negative times negative is positive. So, f(x) will be positive for (-5, 3).

B is not correct.

Choice C)

(-∞, 1).

Choosing 0, we can see that:

\((0+5)(0-3)=-3<0\)

Negative times a negative is positive. So, it seems that C is correct.

However, notice that the domain (-∞, 1) contains two roots: x = -5 and x = 1.

In reality, we only tested (-5, 1). We have yet to test (-∞, -5). So, by using -6 again:

\((-6+5)(-6-3)=(-1)(-9)=9\)

Positive times negative is negative.

So, f(x) is both positive and negative for (-∞, 1).

C is not correct.

Note: We did not need to double-check for B since it was already false.

Choice D)

(3, ∞)

This only has one root.

And using 4, we see that:

\((4+5)(4-3)=1>0\)

Positive times a negative will be negative.

Hence, f(x) will be negative for (3, ∞).

Choice D is the correct answer.

Given that the equation of the line in the diagram is `y = 5 - x`. The line cuts the y-axis at P. So, the coordinates of point P are (0,5) and the gradient of the line is `-1`.

The equation of the line can be written as `y = -1x + 5`.Therefore, the y-intercept of the line is 5. Therefore, the coordinates of point P are (0,5).

To find the gradient of the line, we have to write the equation of the line in the form of `y = mx + c`.

We can rewrite `y = -1x + 5` as `y = (-1)x + 5`.From the above form of the equation, we can see that the gradient `m` is `-1`.Therefore, the gradient of line 1 is `-1`.Hence, the required answer is: Coordinates of point P is `(0,5)`.The gradient of the line is `-1`.

It appears that a Type II error was made in the hypothesis test conducted by the user.

A Type II error, also known as a "false negative," is a statistical error that occurs when a null hypothesis is actually true, but a hypothesis test fails to reject the null hypothesis, leading to the incorrect conclusion that there is no significant effect or difference when, in fact, there is.

According to the given information:

Based on the given information, it appears that a Type II error was made in the hypothesis test conducted by the user.

In this case, the user claimed that the mean number of shades the toothpaste whitens teeth is less than four, and conducted a hypothesis test to test this claim. However, the given information states that the true mean number of shades the toothpaste whitens teeth is actually four. If the user failed to reject the null hypothesis, it means that they did not find enough evidence to support their claim that the mean number of shades is less than four, even though it is actually true.

This would be a Type II error because the null hypothesis (which assumes that the mean number of shades is four) is actually true, but the test failed to detect this and erroneously failed to reject the null hypothesis. In other words, the user made an error in concluding that there is no significant effect or difference, when in fact there is.

There are 36 cards in the box.  In this scenario, we are given that the probability of choosing a red card from a box is one-third. We also know that there are 24 blue cards in the box. Our goal is to find the total number of cards in the box.

Let's use the concept of probability to solve this problem. The probability of an event is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes. In this case, the probability of choosing a red card is given as 1/3, and the favorable outcome is selecting a red card. Let R be the number of red cards, and T be the total number of cards in the box. The probability formula can be represented as:

Probability of choosing a red card = R / T

We are given that the probability of choosing a red card is 1/3:

1/3 = R / T

Since there are 24 blue cards in the box, we can represent the total number of cards as the sum of red and blue cards:

T = R + 24

Now, we can solve the system of equations to find the values of R and T:

1. 1/3 = R / T
2. T = R + 24

From equation 1, we can express R as:

R = (1/3) * T

Substitute this expression for R in equation 2:

T = (1/3) * T + 24

Multiplying both sides by 3 to eliminate the fraction, we get:

3T = T + 72

Subtracting T from both sides:

2T = 72

Now, divide by 2 to find the total number of cards, T:

T = 36

So, there are 36 cards in the box.
