Andru [333]

Answer:

The tree is 28 feet tall.

Step-by-step explanation:

It is given that:

Height of flag pole = 8 feet

Shadow of flag pole = 6 feet

Ratio of height to shadow = 8 : 6

Shadow of nearby tree = 21 feet

Height of nearby tree = x

Ratio of height to shadow = x : 21

8 : 6 :: x : 21

Product of means = Product of extremes

6x = 8*21

6x = 168

Dividing both sides by 6

$\frac{6x}{6}=\frac{168}{6}\\x=28$

Therefore,

The tree is 28 feet tall.

On a river you must release any fish that you catch ifvit measures less than 12 inches. Define a variable and then write an alge

malfutka [58]

Let f = fish

If f < 12, let the fish go.

We cannot catch a fish measuring 11.99 inches.

If f = fish, then f < 11.99. It must be released.
