-3/8 divide 7/12 is equal to -3/8 times 12/7 so you than multiply which would give you -9/12. The way to solve this is you Keep -3/8 the same than Change you division sign to Multiplication than Flip 7/12 to 12/7.

Your answer is -9/12.

Answer:

-9/14

Step-by-step explanation:

This is my simplest-

Do the keep-change-flip method for this problem (and also any problem involving this)

KEEP -3/8

CHANGE the division sign to multiplication

FLIP the last fraction. 7/12 to 12/7

Now solve the problem by multiplying the fractions

-3/8 × 12/7 =

-3 × 12 = -36

8 × 7 = 56

-36 / 56 =

Simplify it by dividing the numerator (up of the line) and denominator (below the line) to get -9/14

Answer:

$\large\boxed{B.\ \cos(37^o)=\dfrac{x}{14}}$

Step-by-step explanation:

$sine=\dfrac{opposite}{hypotenuse}\\\\cosine=\dfrac{adjacent}{hypotenuse}\\\\tangent=\dfrac{opposite}{adjacent}\\\\\text{We have}\ adjacent=x\ \text{and}\ hypotenuse=14.\\\text{Therefore it's a cosine.}$

You are given an n×n board, where n is an even integer and 2≤n≤30. For how many such boards is it possible to cover the board wi

faltersainse [42]

Answer:

Step-by-step explanation:

The number of cells in a tile is 4. If colored alternately, there are 3 of one color and 1 of the alternate color. To balance the coloring, an even number of tiles is needed. Hence the board dimensions must be multiples of 4.

In the given range, there are 7 such boards:

4×4, 8×8, 12×12, 16×16, 20×20, 24×24, and 28×28

35 women's shoes are formal.

52 women's shoes are casual.

The total number of women's shoes is 107. So the probability that a randomly selected one is casual is:

P = 52/107

P ≈ 48.6%

Find the angle [OA] makes with the positive x-axis if the x-coordinate of the point A on the unit circle is 0.222

EastWind [94]

By using the concepts of unit circle and trigonometric functions, we find that the angle OA, whose x-coordinate is 0.222, has a measure of approximately 77.173°.

<h3>How to find an angle in an unit circle</h3>

Unit circles are circles with radius of 1 and centered at the origin of a Cartesian plane, which are used to determine angles and trigonometric functions related to them. If we use rectangular coordinate system and the definition of the tangent function, we find that the angle OA is equal to:

$\tan \theta = \frac{\sqrt{1 - x^{2}}}{x}$

$\tan \theta = \frac{\sqrt{1-0.222^{2}}}{0.222}$

tan θ ≈ 77.173°

By using the concepts of unit circle and trigonometric functions, we find that the angle OA, whose x-coordinate is 0.222, has a measure of approximately 77.173°.

ch4aika [34]

Answer:

-4/3

Step-by-step explanation:

If the lines are parallel, they have the same slope.

Since the red line has a slope of -4/3, the green line will have a slope of -4/3
