The expression equal to 2x^(2)+8 is:

First option (2x-4i)(x+2i)

Step-by-step explanation:

If we multiply

(2x-4i)(x+2i)=(2x)(x)+(2x)(2i)-(4i)(x)-4i(2i)

(2x-4i)(x+2i)=2x^(1+1)+4xi-4xi-8i^(1+1)

Simplifying:

(2x-4i)(x+2i)=2x^2-8i^2

and i^2=-1, then:

(2x-4i)(x+2i)=2x^2-8(-1)

Multiplying:

(2x-4i)(x+2i)=2x^2+8

To find the expression that is equal to 2x^(2) + 8, simplify each option by expanding the multiplication and then compare it to the original expression.

To find the expression that is equal to 2x^(2) + 8, we need to simplify each option by expanding the multiplication and then compare it to the original expression.

Let's simplify each option:

The expression that is equal to 2x^(2)+8 is (2x-4i)(x-2i).

The graph is missing. So is the set of data point values. However, I can assume that as the temperature goes up, then so does the sale of ice cream. It's not a perfect relationship, but there is a strong positive correlation between the two variables.

A positive correlation means that as one variable increases, so does the other. Also, it means that if one variable decreases, then the other variable decreases as well. The two variables move in the same direction together.

Answer:

two irrational numbers are [tex]\sqrt{0.3},\sqrt{0.4}[/tex]

Step-by-step explanation:

We are given to find irrational number

we know that

irrational numbers are numbers that can not be represented as simple fraction

For example:

[tex]\sqrt{2} ,e,\pi[/tex]

but those irrational numbers should be between 0.3 and 0.7

so, we can take sqrt numbers between 0.3 and 0.7

we know that

[tex]\sqrt{0.3}=0.5477[/tex]

[tex]\sqrt{0.4}=0.632455[/tex]

Both values lies between 0.3 and 0.7

The inequality to represent the situation is 335 + d ≥ 575; Rhonda must collect at least '240 stamps' in order to reach her goal.

If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.

Given that the Stamps Rhonda wants to collect = 575

The Stamps already in collection = 335

Let consider 'd' represents the number of stamps Rhonda needs to achieve her goal.

Thus, the Stamps to collect + Stamps already in collection ≥ 575

d + 335 ≥ 575

d ≥ 575 - 335

d ≥ 240

Answer:

12 and 136

Step-by-step explanation:

12 divided by 2 is 6, and 136 divided by 2 is equal to 68.

For the two numbers the quotient is between 136 divided by 6 will be 22 and 23.

We may examine the division and take into account the closest whole numbers to the quotient in order to get the two numbers that are the product of 136 divided by 6.

(Rounded to four decimal places) 136 divided by 6 equals 22.6667. 22 and 23 are the whole numbers that are most similar to this quotient.

We may then deduce that the value of the quotient of 136 divided by 6 is between 22 and 23. Accordingly, the outcome of the division of 136 by six will be a number more than or equal to 22 but less than 23. To put it another way, the quotient falls between [22, 23].

Final answer:

To cover the entire cost of the trip, each student must sell at least 80 sweatshirts.

Explanation:

To find out how many sweatshirts each student must sell, we need to calculate the total cost of the trip and then divide it by the profit per sweatshirt. The total cost of the trip is the sum of the ticket price for each student and the cost of transportation and meals for everyone:

Total Cost = (Ticket Price * Number of Students) + Transportation and Meals Cost

Substituting the given values, we have:

Total Cost = ($35 * 16) + $960

Total Cost = $560 + $960

Total Cost = $1520

Now, we can calculate the number of sweatshirts each student must sell to cover the total cost of the trip:

Number of Sweatshirts = Total Cost / Profit per Sweatshirt

Substituting the given profit per sweatshirt value, we get:

Number of Sweatshirts = $1520 / $19

Number of Sweatshirts = 80

Therefore, each student must sell at least 80 sweatshirts to cover the entire cost of the trip.

The type of angle that is not formed by two parallel lines cut by a transversal is complementary angles. So option (d) is correct.

The intersection of two parallel lines by a transversal forms several types of angles:

1. Alternate Interior Angles: These are angles on opposite sides of the transversal and inside the parallel lines. They are congruent.

2. Alternate Exterior Angles: These are angles on opposite sides of the transversal and outside the parallel lines. They are also congruent.

3. Corresponding Angles: These are angles in the same position at each intersection. They are congruent when the parallel lines are cut by a transversal.

4. Complementary Angles: These are angles whose measures sum up to 90 degrees. They can be formed when a transversal intersects parallel lines, but they are not a specific type of angle formed by this intersection.

Therefore, the type of angle that is not formed by two parallel lines cut by a transversal is D) complementary angles. The other options, A) alternate interior angles, B) alternate exterior angles, and C) corresponding angles, are all formed by this intersection.

Answer:

3. The mean will increase more than median, but both will increase.

Step-by-step explanation:

We have been given a dot plot. We are asked to find the true statement, if a new data point at 12 is added to our given dot plot.

Since we know that an large valued outlier affects mean more than median, so mean will increase more than median.

Let us check this using our given information. Our data set before adding 12 is:

1, 2, 2, 2, 3, 4, 4, 4, 5.

We can see that our data set has odd number (9) of data points, so median will be the value of 5th term, that is 3.

[tex]\text{Mean}=\frac{1+2+2+2+3+4+4+4+5}{9}[/tex]

[tex]\text{Mean}=\frac{27}{9}=3[/tex]

Therefore, mean of our data set is 3.

Upon adding a data point at 12, our new data set will be:

1, 2, 2, 2, 3, 4, 4, 4, 5, 12.

Now our data set has 10 terms, so median will be the average of 5th and 6th term.

[tex]\text{Median}=\frac{3+4}{2}[/tex]

[tex]\text{Median}=\frac{7}{2}=3.5[/tex]

Therefore, the median of new data set will be 3.5.

[tex]\text{Mean}=\frac{1+2+2+2+3+4+4+4+5+12}{10}[/tex]

[tex]\text{Mean}=\frac{39}{10}[/tex]

[tex]\text{Mean}=3.9[/tex]

Therefore, mean of new data set will be 3.9.

Upon looking at our given statements we can see that 3rd statement is true as mean and median both increased after adding 12 to our data set, but mean increased more that median. Mean and median before adding 12 was 3; but after adding 12 median became 3.5, while mean became 3.9 (which is greater than mean).

Answer:

The mean will increase more than the median, but both will increase.

To find the result of dividing 22.11 by 11, you simply divide 22.11 by 11, yielding an answer of 2.01. This basic division operation demonstrates how to divide a decimal by a whole number.

Explanation:

The question is asking to divide 22.11 by 11. To solve this, you would take the number 22.11 and divide it by 11. Dividing these numbers is straightforward and can be done using long division or a calculator.

Step 1: Place 22.11 under the division bracket and 11 outside of it.

Step 2: Determine how many times 11 fits into 22.11. Since 11 goes into 22 exactly two times, you write 2 above the division bracket, aligned with the last digit of 22.

Step 3: Multiply 2 (the quotient) by 11 (the divisor) to get 22, and subtract this from 22.11, leaving you with a remainder of 0.11.

Step 4: Bring down the next digit (if any), but since we already have no more digits left in 22.11, we look at the remainder. In practical terms for simple school-level math, we can stop here, acknowledging that 11 goes into 22.11 twice without a perfect division due to the decimal.

The actual answer to 22.11 divided by 11 is 2.01.

d=7 and q+0=17

Step-by-step explanation:

I will solve your system by substitution.

(You can also solve this system by elimination.)

d+q=24;0.10d+0.25q=4.95

Step: Solve d+q=24 for d:

d+q+ (−q) =24+(−q) (Add -q to both sides)

d=−q+24

Step: Substitute −q +24 for d in 0.10d+0.25q=4.95:

0.10d+0.25q=4.95

0.10(−q+24)+0.25q=4.95

0.15q+2.4=4.95 (Simplify both sides of the equation)

0.15q+2.4+(−2.4) =4.95+(−2.4) (Add -2.4 to both sides)

0.15q+0=2.55

0.15q+0 /0.15  = 2.55/0.15   (Divide both sides by 0.15)

q+0=17

Step: Substitute 17 for q in d= −q+24:

d= −q+24  

d= −17+24

d=7  (Simplify both sides of the equation)

Answer:

Cost of 11 cans of Dog food is $9.57

Step-by-step explanation:

Cost of 5 cans of dog food = $4.35

So to find out the cost of 11 cans of dog food at the same price, we need to calculate the price of 1 can of dog food.

Calculation for finding out cost of 1 can of dog food

The price $4.35 which is given is the price of 5 cans

So to find the cost of 1 can, we need to divide the given price by 5

5 Cans of dog food = $4.35

1 can of dog food = 4.35 ÷ 5

1 can of dog food = $0.87

Now to find out the price of 11 cans, we will multiply the price of 1 can with 11

Cost of 11 cans = 11 × $0.87

                          = $9.57

Answer:

1 ft³

Step-by-step explanation:

The formula for the volume of a cube is  

Vol. = l³ = l × l × l

If l = 1 ft,

V = 1 ft × 1 ft × 1 ft

V = 1 ft³

The volume of the cube with each side measuring 1 foot is 1 cubic foot, calculated by the formula V = 1 ft × 1 ft × 1 ft or simply V = s³.

The volume of a cube can be determined by multiplying its three dimensions together. In this case, the cube has dimensions of 1 foot in length, 1 foot in width, and 1 foot in height. The formula for the volume of a cube is V = length  imes width  imes height. Therefore, for a cube with all sides of 1 foot each, the volume is straightforwardly calculated as:

V = 1 ft × 1 ft × 1 ft = 1 cubic foot.

The properties of a cube tell us that all sides are equal, and thus, to find the volume, we can also use the expression V = s³, where s is the length of a side of the cube. Since each side is 1 foot, the volume is indeed 1 cubic foot or 1 ft³. This simple calculation is a great example of how to apply geometric principles to find volume.

Answer: 2 solutions.

The given equation breaks down into these two equations

3x+12 = 18 and 3x+12 = -18

Basically 3x+12 equal to plus 18 and minus 18. This is due to the fact that something like |x| = 7 means x = 7 or x = -7, ie those x values are exactly seven units away from zero on the number line.

If you want to solve each equation, then

3x+12 = 18

3x = 18-12

3x = 6

x = 6/3

x = 2 is one solution

and

3x+12 = -18

3x = -18-12

3x = -30

x = -30/3

x = -10 is the other solution

Answer: In a right triangle, the sum of the squares of the two legs equals the square of the hypotenuse. Legs (a and b): the sides of the triangle adjacent to the right angle. They don't need to be the same length in order for this theorem to work.

If the sum of the squares of the legs of a triangle doesn’t equal the square of the hypotenuse, the triangle is not a RIGHT triangle.

We know that in a right angled triangle the Pythagorean Theorem hold true.

According to Pythagorean Theorem:

If the three sides lengths of a triangle are a,b and c respectively such that:

          [tex]c^2=a^2+b^2[/tex]

Then such a triangle is a right triangle with hypotenuse c and other two legs of triangle as a and b.

                            Hence, the answer is:

                       The triangle is not a right triangle.

Final answer:

The school can donate $816 to charity from the adult ticket sales of their comedy show, based on the 204 adult tickets sold at $4.00 per ticket.

Explanation:

To find out how much the school can donate, first, determine the number of adult tickets sold. Since half of the 408 tickets are adult tickets, there are 204 adult tickets sold (408 tickets × 1/2 = 204 adult tickets). Next, calculate the total donation from these adult tickets by multiplying the number of adult tickets by the donation per ticket, which is $4.00.

Total Donation = Number of Adult Tickets × Donation per Adult Ticket = 204 × $4.00 = $816.

Therefore, the school can donate $816 to charity from the comedy show ticket sales.

Answer:

$ 816 is donated to charity.

Step-by-step explanation:

408 tickets were sold. 1/2 were adult tickets so

408 * 1/2 = 204 adult tickets were sold.

4 dollars from each adult ticket is donated to charity

204 * 4 =816

$ 816 is donated to charity.
