well, our origin amount will be 80, so 80 is the 100% or all papers, now, she has graded 60, so what's leftover is 20, what's 20 off of it in percentage?

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 80 & 100\\ 20& x \end{array} \implies \cfrac{80}{20}~~=~~\cfrac{100}{x} \\\\\\ 4 ~~=~~ \cfrac{ 100 }{ x }\implies x=\cfrac{100}{4}\implies x=25[/tex]

Hi there!

[tex]\large\boxed{t = 12.60 \text{ days}}[/tex]

We can solve this by setting the equation equal to 150:

[tex]150 = \frac{230}{1 + 56.5e^-0.37t}[/tex]

Cross-multiply and divide:

[tex]150 (1 + 56.5e^{-0.37t})= 230[/tex]

Divide both sides by 150:

[tex]1 + 56.5e^{-0.37t} = 1.5333[/tex]

Isolate for t by subtracting both sides by 1 and dividing by 56.5:

[tex]56.5e^{-0.37t} = 0.5333[/tex]

[tex]e^{-0.37t} = 0.0094395[/tex]

Take the natural log to solve for t:

[tex]ln (0.0094395) = -0.37t[/tex]

[tex]-4.6628522 = -0.37t[/tex]

Divide both sides by -0.37:

t = 12.60 days.

The expression determines the quantity of water leaving the tank per hour is (18 1/2 gallons)/(4 1/4 hours)

Rate is the ratio of a certain number of units of one quantity to units of another quantity. Mathematically, rate is one quantity divided by the other quantity.

If a total of 18 and one-half gallons flowed out of the tank in 4 and one-fourth hours. We can write that the rate as follows:

rate = (18 1/2 gallons)/(4 1/4 hours)

rate = 4 6/17 gallons per hour

Thus, the expression determines the quantity of water leaving the tank is (18 1/2 gallons)/(4 1/4 hours)

The difference between their ages is obtained as 35/12.

Let us recall that the term fraction has to do with a part of a whole. In this case, we have been told that Marcelle and Megan realized that they could express their ages more specifically if they used fractions.

Age of Marcelle  = 15 1/2 or 31/2 years

Age of Megan  = 12 7/12 or 151/12 years

The difference between their ages is;

31/2 - 151/12

=186 - 151/12

=35/12

There ages would have a difference of 35/12.

In the computation that has gone on above, we can clearly see that the difference in the ages is 35/12.

Starting out with the fraction of 5/9, Jess would be thinking of the fraction 144/125 at the end of the game if the ten coin flips turn out to be {THTTHTHTTT}.

Since both outcomes are equally likely, the probability of getting heads is 0.5 and the probability of getting tails is also 0.5. Alternatively, the probability of getting H or T in a coin flip is 1.

Probability is an important method for comprehending and making judgments regarding uncertain occurrences in many disciplines, including statistics, finance, and science. It aids in quantifying and forecasting the probability of specific events, enabling us to make better educated choices and comprehend the degree of risk involved with various activities. In summary, probability is a key idea in decision-making and risk management because it is a potent instrument for comprehending and managing uncertainty.

Taking the sequence of coin flips in ten tires, i.e THTTHTHTTT , and starting from the fraction 5/9, the fraction that jess would be thinking at the end of the game can be calculated as,

5/9 * (6/5)^7 *(5/6)^3 , since there are 7 Tails and 3 Heads during the whole game. Which is equal to the fraction 144/125.

The measure of angle E if The measure of angles is 2x + 13, 11x - 6 and 89°, is 37°.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles.

Given:

The measure of angles is 2x + 13, 11x - 6 and 89°,

Use the exterior angle theorem and find the value of x as shown below,

2x + 13 + 89 =  11x - 6

2x + 102 = 11x - 6

9x = 108

x = 12

Thus, the measure of ∠ E = 2 × 12 + 13

∠ E = 24 + 13

∠ E = 37°

By adding a duplicate of the identity matrix to the augmented matrix, which was formed, it is possible to find the inverse of a square matrix using row reduction.

If the matrix is capable of being reduced to the identity, the identity matrix will simultaneously change into the inverse matrix. A rectangular array of numbers, arranged in rows and columns, is referred to as a matrix. The dimension, or order, of a matrix, indicates how many rows and columns there are in the array. For example, if a matrix has m rows and n columns, its order is expressed as mxn.

Answer:

  It isn't.

  The correct relation is 4r·Area = abc.

Step-by-step explanation:

You want to show the relation between the product of triangle side lengths and the product of the triangle area and the radius of the circumcircle.

The area of the triangle in the attached diagram can be found by ...

  Area = 1/2(bc)sin(α)

The inscribed angle theorem tells you the measure of the arc subtended by an inscribed angle is twice the measure of the inscribed angle. That means the opposite chord will be twice the length of the product of the radius and the inscribed angle value:

  a = 2r·sin(α)

The product of the circumradius and the area of the triangle is ...

  r·Area = r·(1/2)(bc)sin(α) = 1/4(bc)(2r·sin(α)) = 1/4abc

Without the fractions, the relation is ...

  4r·Area = abc

__

Additional comment

As a simple example, consider a 3-4-5 right triangle. The area of the triangle is ...

  A = 1/2(3)(4) = 6

The circumradius is half the length of the hypotenuse, r = 5/2.

The relation of interest is ...

  4r·Area = abc

  4(5/2)(6) = 3·4·5

  60 = 60 . . . . . . . . . . as expected

This could be a very simple way to find the circumradius of a triangle.
