Answer:

All four are linear
Slopes: 2, 1/2, - 2/3, 3/4

Step-by-step explanation:

<u>Rate of change is same for each step:</u>

10 per each 5

<u>Slope is:</u>

(25 - 15)/(5 - 0) = 10/5 = 2

<h3>Top right</h3>

<u>Rate of change is same for each step:</u>

1 per each 2

<u>Slope is:</u>

(6 - 5)/(3 - 1) = 1/2

<h3>Bottom left</h3>

<u>Rate of change is same for each step:</u>

-2 per each 3

<u>Slope is:</u>

(30 - 32)/(5 - 2) = -2/3

<h3>Bottom right</h3>

<u>Rate of change is same for each step:</u>

3 per each 4

<u>Slope is:</u>

(20 - 17)/(5 - 1) = 3/4

Use the fact that 2 1/2 divide 1/8 =20 to find 2 1/2 divide 5/8

Tasya [4]

Answer:

Step-by-step explanation:

Given that $2\frac 1 2 \div \frac 1 8 =20$

$\Rightarrow \frac 5 2 \div \frac 1 8 =20$

$\Rightarrow \frac 5 2 \times 8 1 =20 \cdots(i)$

Now, $2\frac 1 2 \div \frac 5 8$ $= \frac 5 2 \div \frac 5 8$ $=\frac 5 2 \times \frac 8 5$

This can be written as

$\frac 5 2 \times \frac 8 5=\frac 5 2 \times \left( \frac 8 1 \times \frac 1 5\right)$ [as $\frac 8 5=\frac 8 1 \times \frac 1 5$ ]

$=\left(\frac 5 2 \times \frac 8 1 \right)\times \frac 1 5$

$=20 \times \frac 1 5$ [ by using equation (i)]

Hence, $2\frac 1 2 \div \frac 5 8=4$

Answer:

16 miles

Step-by-step explanation:

The problem can be modeled by a right triangle with one angle of 7° and the side opposite being 10,000 ft. The distance needed is the hypotenuse of the triangle, so the relevant trig relation is ...

Sin = Opposite/Hypotenuse

Hypotenuse = Opposite/Sin

air distance = (10,000 ft)/sin(7°) ≈ 82,055 ft

At 5,280 ft per mile, that is ...

(82,055 ft)/(5,280 ft/mi) ≈ 15.54 mi

The plane's air distance to the airport is about 16 miles.
