Answer: 12 miles per hour.

Step-by-step explanation:

Given: Distance travelled = $\dfarc16\ mile$

Time taken = $\dfrac1{72}$ hour

Unite rate = speed

The formula for speed is given by:-

$speed =\dfrac{Distance}{Time}$

So, unit rate = $\dfrac{\dfrac{1}{6}}{\dfrac{1}{72}}\ mile/ hour$

$=\dfrac{72}{6}\ mile /hour\\\\=12\ miles /hour$

Hence, unit rate = 12 miles per hour.

Janelle wrote the matrix addition below. Which statement is true?

Sonja [21]

Option A is correct.

Step-by-step explanation:

We need to identify which statement is true in matrix addition.

In matrix addition we just add the corresponding elements.

In the options given only Option A is correct i.e, (n+4)-7 = 18

All other options have error in them.

In Option B there should be -12 instead of +12

In Option C there should be -11 instead of 11

In Option D we are not adding corresponding entries.

So, Option A is correct.

Solve for y: x + 2y = -8 y=-1/2x+4 y=-1/2x-4 y=-2x - 4 y=1/2x-4

adelina 88 [10]

Answer:

x + 2y = -8 = y = -4 - 1/2x

y= -1/2x + 4 = y = 4

y= -1/2x - 4 = y = -4

y=-2x - 4 = y = -4

y=1/2x-4 = y = -4

Step-by-step explanation:

(x + 2y = -8 = y = -4 - 1/2x)

$x+2y=-8\\2y=-8-x\\y=-4-\frac{1}{2}x\\$

Find the value of tanθ, if cosθ = 4/5 ; 0° ≤ θ< 90°

Montano1993 [528]

Answer:

Step-by-step explanation:

Given

cosθ = 4/5
0° ≤ θ < 90°

In the first quadrant both sine and cosine are positive, so as tangent.

tanθ = sinθ / cosθ =
$\sqrt{1 - cos^2}$ θ / cosθ =
$\sqrt{1 - (4/5)^2}$ / 4/5 =
$\sqrt{9/25}$ / 4/5 =
3/5*5/4 =
3/4
