Answer: 12.5

Step-by-step explanation: 2times 12.5 is 25

Answer:

5 days

Step-by-step explanation:

To find out this question, we can subtract the amount she wants to get, 25, by the amount she has, 15:

25 - 15 = 10

So, Jomaya wants to save up $10, and because she saves $2 every day, we can divide:

10 / 2 = 5

So, it will take Jomaya 5 days to save $25

The solutions of the given equation are 3.16, 1, and - 1.  

All numbers that make an equation true when the unknowns are eliminated from the equation are considered the solution of the equation.

For the given equation, we can find the solutions by factorizing as shown below.

Here finding the factors of the given polynomial is known as Factorizing. In other words, writing the given equation as a product of its factors.

Here we have

x⁴ - 11x² + 10 = 0

We can solve the above equation as follows

x⁴ - 11x² + 10 = 0

x⁴ - 10x² - x²  + 10 = 0    

Group out the like terms

x²(x² - 10) - (x² - 10) = 0

(x² - 10) (x² - 1) = 0

(x² - 10) (x - 1)(x + 1)  = 0    [ ∵ (x² - 1²) = (x - 1)(x + 1) ]    

x² - 10 = 0 => x = √10 = 3.16  

x - 1 = 0 => x = 1

x + 1 = 0 => x = -1

Therefore,

The solutions of the given equation are 3.16, 1, and - 1.

The measure of angle A in triangle ABC is approximately 53.14 degrees.

To find the measure of angle A in triangle ABC, we can use the Law of Cosines. The Law of Cosines states that in a triangle, the square of one side is equal to the sum of the squares of the other two sides minus twice the product of the two sides multiplied by the cosine of the included angle.

In this case, we have sides a, b, and c with respective lengths of 20m, 14m, and 16m. Let's denote angle A as ∠A.

According to the Law of Cosines, we have the following equation:

c^2 = a^2 + b^2 - 2ab * cos(∠A)

Plugging in the given values, we have:

16^2 = 20^2 + 14^2 - 2 * 20 * 14 * cos(∠A)

Simplifying this equation further:

256 = 400 + 196 - 560 * cos(∠A)

256 = 596 - 560 * cos(∠A)

Rearranging the equation:

560 * cos(∠A) = 596 - 256

560 * cos(∠A) = 340

Now, we can solve for cos(∠A) by dividing both sides by 560:

cos(∠A) = 340 / 560

cos(∠A) ≈ 0.607

To find the measure of angle A, we need to take the inverse cosine (cos^(-1)) of 0.607:

∠A ≈ cos^(-1)(0.607)

Using a calculator, we find:

∠A ≈ 53.14 degrees

Therefore, the measure of angle A in triangle ABC is approximately 53.14 degrees.

The business can anticipate losing roughly $55.20 as a result of subpar inspections.

Probability is a measure of the likelihood or chance of an event occurring. It is usually expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

If the bottles pass inspection with probability 98/100, then they fail inspection with probability 1 - 98/100 = 2/100 = 0.02.

Out of 800 bottles of laundry detergent, we can expect about 0.02*800 = 16 bottles to fail inspection.

The cost to the company for each failed bottle is $3.45, so the total cost to the company is approximately 16*$3.45 = $55.20.

Therefore, the company can expect to lose about $55.20 due to failed inspections.

The area of the right triangle is 24 square yards.

Hence, the correct option is b. 24 yards squared.

To find the area of a right triangle, we can use the formula:

\(Area = (1/2) \times base \times height.\)

In this case, the base is 6 yards and the hypotenuse is 10 yards.

We need to find the height of the triangle.

By using the Pythagorean theorem, we can determine the height:

\(height^2 + base^2 = hypotenuse^2\)

\(height^2 + 6^2 = 10^2\)

\(height^2 + 36 = 100\)

\(height^2 = 100 - 36\)

\(height^2 = 64\)

Taking the square root of both sides:

height = √64

height = 8

Now we can substitute the values into the area formula:

\(Area = (1/2) \times base \times height\)

\(Area = (1/2) \times 6 \times 8\)

Area = 24

The world record for memorizing and reciting the most digits of pi is held by Rajveer Meena from India. He recited 50,000 decimal places of pi in 2020, which is the current recognized world record.

Pi (π) is a mathematical constant that represents the ratio of a circle's circumference to its diameter. It is an irrational number, which means it cannot be expressed as a finite decimal or a fraction. The decimal representation of pi is non-repeating and goes on indefinitely without a pattern. The value of pi is approximately 3.14159, but it is commonly approximated as 3.14 for simplicity in mathematical calculations. However, the exact value of pi has been calculated to trillions of digits using various computational methods. The quest to calculate more digits of pi continues to this day, and the computation of pi serves as a benchmark for testing the performance of supercomputers and computational algorithms. The current record for calculating the most digits of pi is trillions of digits, achieved through the use of powerful computers and advanced algorithms.

A reasonable estimate for the number of green marbles in the bag would be around 250, since the marbles are split evenly between green and yellow. This means that for each student selecting 10 marbles, on average 5 of them should be green.

To estimate the number of green marbles in the bag, we can use the fact that the marbles are split evenly between green and yellow. This means that for each student selecting 10 marbles, on average 5 of them should be green. This means that, with 20 students selecting 10 marbles each, we can expect to have at least 100 green marbles. We can then multiply this number by two to get a reasonable estimate of 200 green marbles. Since this is a slightly conservative estimate, we can round up to 250 green marbles for our reasonable estimate.

Step-by-step explanation:

A triangle with given vertices have (-1,5/2) as circumcenter, (1,40 as orthocenter and [-1/3, 3] as centroid.

A right triangle is one that has an interior angle of 90 degrees. The hypotenuse, which is also the side of the right triangle that faces the right angle, is its longest side. The height and base make up the two arms of the right angle.

The intersection of the perpendicular bisectors of a triangle's sides is known as the circumcenter of that particular triangle. In other terms, the circumcenter is the point at which the bisector of a triangle's sides coincides.

That's a right triangle, essentially half a rectangle. The common midpoint of the diagonals of a rectangle is equidistant from the four corners. So the midpoint of the hypotenuse is the circumcenter of a right triangle.

That's  1/2*(−3+1,4+1)=(−1,5/2)

To calculate centeroid:

ler (a,b)=(1,1)

(c,d)=(1,4)
