Answer:

<h3>C. Scientific Notation</h3>

Step-by-step explanation:

Since the number in question is greater than or equal to 1 but less than

10, we can choose any number between 1 and 10, lets take 3 for example.

If we take the product of 3 and an integer power of 10 number without regard to its sign, this can be expressed mathematically as shown;

$3 * 10^{-5}$ where the power of 10 is -5. Note that any real number can be used as the power since we are not regarding the sign (Here we used -5). The expression formed according to the expression in question is a SCIENTIFIC NOTATION i.e $3 * 10^{-5}$ gives us a scientific notation.

<em>Scientific notation is a means by which we represent very large or small numbers that are difficult to represent using a decimal notation</em>

Find the value of angle marked x

lyudmila [28]

Based on the given diagram we see that all the exterior angle is in a straight line with the interior angle.

Using the known angle measure, we know that the shape has angles of measure, 123 degrees, 94 degrees, 79 degrees, and '180 - x' degrees

Also, the sum of all the angles in a quadrilateral, any four-sided shape, is 360 degrees.

Now using the knowledge gained lets set up the equation

$123 + 94 + 79 + 180 - x = 360\\476 - x = 360\\-x = -116\\x = 116$

Therefore x is 116 degrees.

Hope that helps!

448 = -5v + 8(-5 - 7v)<br> What is v?

lapo4ka [179]

Answer:

v = -8

Step-by-step explanation:

First we would have to distribute the 8(-5 - 7v). To do this we would multiply 8 by -5 and 8 by -7v to get $448=-5v-40-56v$ . After this, we would have to simplify like terms by subtracting 56v from -5v to get $448=-61v-40$ . We now have to get the variable on one side and to do that, we can add 40 to both sides to get $488=-61v$ . Finally to get the variable alone, we would have to divide both sides by -61 to get $v=-8$ .
