Answer:

4 times as fast

Step-by-step explanation:

To determine how many time as fast, take the rate up and divide by the rate down

63 minutes

--------------------

15 minute 45 seconds

But we need to be all in the same units so change second to minutes by dividing by 60

63 minutes

--------------------

15 minute 45/60 minutes

63 minutes

--------------------

15.75 minute

4 times

Answer:

4 times as fast

Step-by-step explanation:

We need to first convert everything to the same units. Let's change it to seconds. There are 60 seconds in a minute, so 63 minutes is 63 * 60 = 3780 seconds and 15 minutes, 45 seconds is 15 * 60 + 45 = 945 seconds.

Now, in order to find how many times as fast the rate going up was than the rate going down was, we divide the ascending rate by the descending rate:

3780 / 945 = 4

The answer is thus 4 times as fast.

If a 45 degree 45 degree 90 degree triangle has a hypotenuse length of 12 find the leg length

AURORKA [14]

Answer:

<h2>Leg length = 8.5</h2><h2 />

Step-by-step explanation:

let x represent the leg length

if we use the Pythagorean theorem we get:

x² + x² = 12²

then

2x² = 12²

Then

x² = 144/2 = 72

then

x = √(72)

Which linear inequality is represented by the graph?

Tamiku [17]

Answer:

Option (4)

Step-by-step explanation:

From the graph attached,

A dotted line passes through two points (3, 1) and (-3, -3)

Let the equation of the given line is,

y = mx + b

where 'm' = slope of the line

b = y-intercept

Slope of a line passing through $(x_1, y_1)$ and $(x_2,y_2)$ is,

m = $\frac{y_2-y_1}{x_2-x_1}$

For the given points,

m = $\frac{1+3}{3+3}$

m = $\frac{2}{3}$

y-intercept 'b' = -1

Therefore, equation of the given line will be,

$y=\frac{2}{3}x-1$

Since graphed line is a dotted line so it's representing an inequality(having < or > sign)

And the shaded part is below the dotted line,

Inequality will be,

y < $\frac{2}{3}x-1$

Therefore, Option (4) will be the answer.
