a flag pole that is 8 feet tall casts a shadow that is 6 ft long a nearby tree casts a shadow that is 21 ft long. How tall is th

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.

here are five rods a-1 a a a a+3 all measurements are in cm the total length of the five rods is l cm find a formula for l in te

Elenna [48]

Answer:

$I=5a+2$ (simplified form)

Step-by-step explanation:

I is the total length of all the 5 rods.

Each of the 5 parts lengths are $(a-1), a, a, a, (a+3)$ , respectively.

We add all of them and equate it to I:

$I=(a-1)+a+a+a+(a+3)$

Simplifying this, we take like terms and add:

$I=(a-1)+a+a+a+(a+3)\\I=5a-1+3\\I=5a+2$
