An algebraic expression is a combination of terms both constants and variables. For example -

Given is to divide (3x³ - 2x² +4x - 3) by (x² + 3x + 3).

Let us assume that -

f(x) = (3x³ - 2x² + 4x - 3)

g(x) = (x² + 3x + 3)

We can write -

h(x) = f(x)/g(x)

h(x) = (3x³ - 2x² + 4x - 3)/(x² + 3x + 3)

h(x) = 3x + {(- 11x² - 5x - 3)/(x² + 3x + 3)}

h(x) = 3x - 11 + {(28x + 30)/(x² + 3x + 3)}

Therefore, on dividing (3x³ - 2x² + 4x - 3) by (x² + 3x + 3), we get -

h(x) = 3x - 11 + {(28x + 30)/(x² + 3x + 3)}.

Answer:

  $2.21

Step-by-step explanation:

You want to know the savings between using a $10 off coupon and taking a 15% discount, if the tax rate is 10.3%.

The price with the coupon is ...

  $79.99 -10.00 = $69.99

When tax is added, the total becomes ...

  $69.99 × 1.103 ≈ $77.20

The price with the discount is ...

  $79.99 × (1 -0.15) ≈ $67.99

When tax is added, the total becomes ...

  $67.99 × 1.103 ≈ $74.99

The savings by making use of the discount is ...

  $77.20 -74.99 = $2.21

The total savings between the coupon and the discount is $2.21. That is, you save $2.21 more by using the discount instead of the coupon.

__

Additional comment

The question seems a bit ambiguous. The word "or" suggests you cannot use both discounts. If you do, the total amount saved will depend on the order in which they are applied.

You get the best result by taking the $10 off the sale price. Doing that gives you a total savings of about $24.27 off the normal price with tax.

Answer:

y = 11 when x = 2

Step-by-step explanation:

This is indirect proportionality where:

y ∝ [tex]\frac{1}{x^{2}}[/tex]

This means:

[tex]y_{1} x_{1}^{2} = y_{2}x_{2}^{2}[/tex]

Substitute the following values in the above equation to solve for [tex]y_{2}[/tex]

[tex]y_{1} = \frac{11}{4}[/tex]

[tex]y_{2} = ?[/tex]

[tex]x_{1} = 4[/tex]

[tex]x_{2} = 2[/tex]

= [tex](\frac{11}{4})(4^{2}) = y_{2}(2^{2})[/tex]

= [tex](\frac{11}{4})(16) = y_{2}(4)[/tex]

= [tex]44 = 4y_{2}[/tex]

= [tex]y_{2} =\frac{44}{4}[/tex]

A two-dimensional form having four sides, four vertices, and four angles is referred to as a quadrilateral. Examples are: Trapezium, Parallelogram, Rectangle, Rhombus, Square and Kite.

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.

The Latin words quadra, which means four, and latus, which means sides, are combined to form the English term quadrilateral. A quadrilateral does not always have to have equal lengths on each of its four sides. As a result, depending on the sides and angles, we might have several sorts of quadrilaterals. Hence a Quadrilateral is of 4 sides, vertices and angles. It consists of 360 degrees.

4. The probability of drawing 1 pink, 2 yellow and, stripped ball in succession without replacing the ball each time is (7/16) x (1/35) x (1/13) = 1/2540.

5. The probability that we roll a total of five if we are given that the total is less than nine is (1/36) / (4/36) = 1/4.

6. The probability that both cards are 7s is (6/36) x ($5 - $1) + (30/36) x (-$1) = -$0.17.

7. The expected value of the game is a loss of 17 cents per play.

4. The probability of drawing 1 pink ball, 2 yellow balls, and 1 stripped ball in succession is given by the product of the probabilities of drawing each ball without replacement.

The probability of drawing 1 pink ball is 7/16, the probability of drawing 2 yellow balls is (3/15) x (2/14) = 1/35 (because there are 3 yellow balls in the bag out of 15 total balls on the first draw, and 2 yellow balls out of 14 total balls on the second draw), and the probability of drawing 1 stripped ball is 2/13. Therefore, the probability of drawing 1 pink ball, 2 yellow balls, and 1 stripped ball in succession is:

(7/16) x (1/35) x (1/13) = 1/2540

5. If the total is less than nine, then there are only 4 possible outcomes: (1, 4), (2, 3), (3, 2), and (4, 1). The probability of rolling each of these outcomes is 1/36, since each die has 6 equally likely outcomes. The only outcome that adds up to 5 is (1, 4), which has probability 1/36. Therefore, the probability of rolling a total of 5, given that the total is less than nine, is:

(1/36) / (4/36) = 1/4

6. The probability of drawing a 7 on the first card is 4/52, since there are four 7s in a deck of 52 cards. Since the card is replaced, the probability of drawing a 7 on the second card is also 4/52. Therefore, the probability of drawing two 7s in a row is:

(4/52) x (4/52) = 1/169

7. The expected value of the game is the sum of the products of the outcomes and their probabilities. There are 6 x 6 = 36 possible outcomes, each with probability 1/36. Of these outcomes, 6 are winning outcomes (where both dice show the same number), and 30 are losing outcomes. The payout for a winning outcome is $5, and the cost of playing the game is $1. Therefore, the expected value is:

(6/36) x ($5 - $1) + (30/36) x (-$1) = -$0.17

Therefore, the expected value of the game is a loss of 17 cents per play.

Answer: Let's represent the value of car 1 as x. Then, the value of car 2 is 3/4 of x, and the value of car 3 is 4/5 of the value of car 2.

So, we can write the following equations:

x = (3/4) * y

y = (4/5) * z

Where y is the value of car 2, and z is the value of car 3.

Adding all the values, we have:

x + y + z = 1115900

We can substitute the values of y and z in terms of x:

x + (3/4) * x + (4/5) * (3/4) * x = 1115900

Simplifying the expression on the left side, we get:

7/4 * x = 1115900

Finally, dividing both sides by 7/4, we get:

x = 359900

So, the value of car 1 is $359900, the value of car 2 is (3/4) * x = (3/4) * 359900 = 269925, and the value of car 3 is (4/5) * (3/4) * x = (4/5) * (3/4) * 359900 = 213140.

Step-by-step explanation:

Answer: the value of car 1 is $467125, the value of car 2 is $623033.33, and the value of car 3 is $350937.5.

Step-by-step explanation:

Let's call the value of car 1 "x".

From the first ratio, we know that the value of car 2 is 4/3 times greater than the value of car 1, and the value of car 3 is 3/4 times greater than the value of car 1.

So, the value of car 2 is 4/3 * x, and the value of car 3 is 3/4 * x.

From the second ratio, we know that the value of car 2 is 8/5 times greater than the value of car 3.

So, the value of car 2 is 8/5 * (3/4 * x) = 6/5 * x.

The total value of all three cars is $1115900, so we can set up an equation to solve for x:

x + 4/3 * x + 3/4 * x = 1115900

Expanding and simplifying the right side:

x + 4/3 * x + 3/4 * x = 1115900

8/3 * x = 1115900

x = 1115900 * 3 / 8

x = 467125

So, the value of car 1 is $467125, the value of car 2 is $623033.33, and the value of car 3 is $350937.5.

The formula for converting pounds (lb) to kilograms (kg) is 1 lb = 0.45359237 kg. To convert from lb to kg, you simply multiply the value in lb by 0.45359237.

For example, to convert 186 lb to kg, you would need to perform the following calculation: 186 lb × 0.45359237 kg/lb = 83.99 kg. Therefore, the answer to the question is that 186 lb is equivalent to 83.99 kg. This can be written in a short form as 186 lb = 83.99 kg. It is important to note that this conversion is based on the International System of Units (SI) and is the most commonly used method for measuring weight. When converting between measurements, it is also important to consider the accuracy of the conversion. In this case, the conversion is accurate to nine decimal places. This means that the result is accurate to within 0.000000001 kg, which is an extremely small amount. As such, this conversion should be suitable for most practical applications.

Answer:

22.5 minutes

Step-by-step explanation:

Initially, there were 9 students with 30 minutes to clean up the mess. This means they had a total of 9 · 30 = 270 student minutes to clean up the mess.

After the 3 additional students were added, there were a total of 9 + 3 = 12 students on the clean-up crew.

Now, let's assume the time they need to clean up the mess is "t" minutes. Since the number of students and the time are inversely proportional to the amount of work done, we can set up the following equation based on the idea that the amount of work done is the same before and after the addition of the 3 students:

9 · 30 = 12 · t

Solving for "t":

270 = 12t

t = 270 / 12

t = 22.5

So, the principal should give them approximately 22.5 minutes to complete the job with the new crew of 12 students.
