Model 25% on a 4x3 grid
Nostrana [21]
1.) Start by figuring out what the 4x3 grid would look like. In this grid, we have 12 boxes (4 x 3 = 12).

2.) Now let's calculate 25% of 12. When changing a percent to a decimal, simply move the decimal point over to the left two places. So then 25% = .25 when written as a decimal. Multiply 25 x 12. 25% of 12 equals 3. 

3.) Now your grid would have 3 boxes shaded in. I put two examples of this in the attached image. However, your boxes can be shaded in anywhere in the grid, as long as only 3 of them are shaded in!

What’s the distance between polar coordinates (3,−60°)and(−5,105°) ?
Ilya [14]

Answer:

2 Units

Step-by-step explanation:

THere may be easier ways to do it, but I would just convert them to rectangular and find the distance between those.

(3, -60) becomes (3cos(-60), 3sin(-60)) = (3/2, -3*sqrt(3)/2)

(-5, 105) becomes (-5cos(105), -5sin(105)) = (5/2, -5sqrt(3)/2)

Now just use the distance formula, or in other words think of the two points as being connected by a horizontal and vertical line to form a right triangle.  The idea is to find the hypotenuse of that right triangle.

sqrt((3/2 - 5/2)^2 + (-3sqrt(3)/2 + 5sqrt(3)/2)^2)

sqrt((-2/2)^2 + (2*sqrt(3)/2)^2)

sqrt(1 + 3)

sqrt(4)

(3, 2) and 3-2)<br> Find the slope of the line through each pair
goldenfox [79]

Answer:

<em>m</em> = undef

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Slope Formula: m=\frac{y_2-y_1}{x_2-x_1}

Step-by-step explanation:

<u>Step 1: Define</u>

Point (3, 2)

Point (3, -2)

<u>Step 2: Find slope </u><em><u>m</u></em>

  1. Substitute:                    m=\frac{-2-2}{3-3}
  2. Subtract:                       m=\frac{-4}{0}
  3. Simplify:                        <em>m</em> = undef
