earnstyle [38]

Answer:

36 miles.

Step-by-step explanation:

We have been given that Karina rode her bike up a mountain trail at an average of 4 mph. Then she rode it back down the trail at an average of 20 mph. The entire trip took 3 hours.

$\text{Distance}=\text{Speed}\times \text{Time}$

Substitute the given values:

$\text{Distance}=(\frac{4\text{ miles}}{\text{Hour}}+\frac{20\text{ miles}}{\text{Hour}})\times 3\text{ Hours}$

$\text{Distance}=(\frac{24\text{ miles}}{\text{Hour}})\times 3\text{ Hours}$

$\text{Distance}=24\text{ miles}\times 3$

$\text{Distance}=72\text{ miles}$

The total distance is 72 miles, so the distance going up would be half of 72.

$\frac{72}{2}=36$

Therefore, Karina went 36 miles up the mountain.

The length of a rectangle is 3 times the width. The difference between the length and the width is 8 feet. Determine the rectang

Fynjy0 [20]

Answer:

Width = 4 feet

Step-by-step explanation:

Let l = length

Let w = width

l = 3w

l - w = 8

3w - w = 8

2w = 8

w = 4

Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point E (9,0)

Point F (0, -10)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute [DF]: $d = \sqrt{(0-9)^2+(-10-0)^2}$
Subtract: $d = \sqrt{(-9)^2+(-10)^2}$
Exponents: $d = \sqrt{81+100}$
Add: $d = \sqrt{181}$
Evaluate: $d = 13.4536$
Round: $d \approx 13.5$

Pls help im stuck on this

Law Incorporation [45]

<h3>Answer: Choice C</h3>

The -2/5 means we go to the left 2/5 of a full unit. So we take 2 small little steps (going over 2 little tickmarks), then we move 4 small steps to the right due to the +4/5 portion. Ultimately, we end up at 2/5 as the answer

So -2/5 + 4/5 = 2/5

This can be thought of as -2+4 = 2, then you just stick 5 in the denominator for each term.
