For this case we must find a reasonable estimate, in scientific notation, for a wavelength given by:

0.000000492 meters

If we roll the decimal seven spaces to the right we have:

4.92 * 10 ^ {- 7}\ m

The exponent is negative.

The expression can be written as:

5 * 10 ^ {- 7}\ m

Answer:

Option C

a studernt has pased 60 percent of 20 quizzes he has written so far successfully. if the student 50 quizzes during the year, and
faust18 [17]

Answer:

72%

Step-by-step explanation:

There are a total of 50 quizzes in the year

From the first 20, the student passes 60%. This makes a total of

\frac{60}{100} (20) = 12

12 passes

Out of the remaining 30 quizzes the student passes in 80% of them. This makes a total of

\frac{80}{100} (30) = 12

24 passes

Adding the two values

12 + 24 = 36

The student passes 36 quizzes out of 50.

We convert this to a percentage

\frac{36}{50} (100) = 72%

Which of the following equations is non-linear?
lakkis [162]

2x + 6y = 14y - 19x^2 + 12 is a non-linear equation

Step-by-step explanation:

Lets define a linear equation first.

A linear equation is an equation in which there is no variable with exponent greater than 1 or the degree of the equation is 1.

So,

<u>x + 12 = -8x + 10 - 2y</u>

The equation is a linear equation because the degree of the equation is 1.

<u>x = 8x + 19 - 10y</u>

The equation is a linear equation because the degree of the equation is 1.

<u>2x + 6y = 14y - 19x^2 + 12</u>

The equation involve a term with exponent 2 which makes the degree of the equation 2 making it a quadratic equation

<u>2x + 13y + 14x - 7 = 16y - 3</u>

The equation is a linear equation because the degree of the equation is 1.

Hence,

2x + 6y = 14y - 19x^2 + 12 is a non-linear equation

Keywords: Linear, quadratic

goblinko [34]

Answer:

Percentage of total I have = 80%    

Step-by-step explanation:

Given:

Price of Box = $60

I Have = $48

To Find:

Percentage I have = ?

Solution:

In this question we are just supposed to find out the percentage of the Value we have so

Percentage can be found by the formula

Percentage =\frac{Given Value}{Total}*100%

Now we have the values of all

So putting in the values

Percentage =\frac{48}{60}*100%

                    =\frac{4800}{60}%

                            = 80%

So the Percentage of total cost I have is 80%

Percentage of total = 80%
