Remark
Average in this case does not mean you take (s1 + s2)/2. What average speed means is Total Distance / Total Time.

Formula
Average speed(s) = Total Distance / Total Time

Givens
Total Distance = 252 + 30 = 282 miles
Total Time = 5 hours.

Substitute and Solve
Average speed = 282 / 5
Average speed = 56.4 miles / hour <<<<< Answer.

The other facts are not used.

Convert the equation to y=mxtb <br><br> 2x-3y=-6 please show the steps .

stellarik [79]

You subtract the x from both sides of the equation so it will then be -3y = -2x - 6. You then divide each number by -3, -3y divided by -3, -2x divided by -3, and the - 6 divided by negative 3. It would equal y = 2/3x + 2

What are the ratios for sin A and cos A? The triangle is not drawn to scale.

dalvyx [7]

Answer:

$SinA = \frac{84}{85}$ and $CosA=\frac{13}{85}$

Step-by-step explanation:

The ratios of sine and cos are defined as follows:

$Sin A = \frac{Opposite}{Hypotenuse}$ , and

$CosA = \frac{Adjacent}{Hypotenuse}$

The hypotenuse is always the side opposite of the 90 degree angle (for the given triangle, the hypotenuse is 85)

Since we are looking at the angle A, the opposite side with respect to A would be the side length of 84. That leaves the side 13 as the adjacent side.

Thus, we can now write:

$Sin A = \frac{Opposite}{Hypotenuse}\\SinA = \frac{84}{85}$

$CosA = \frac{Adjacent}{Hypotenuse}\\CosA=\frac{13}{85}$

The correct answer is the first answer choice.
