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.

What is another way to write 7/8x+3/4=-6
Bess [88]

Answer:

7x + 6 =  - 48

Step-by-step explanation:

The given expresion is

\frac{7}{8}x +  \frac{3}{4}  =  - 6

We multiply through by 8 to get:

8 \times \frac{7}{8}x +  8 \times \frac{3}{4}  =  - 6 \times 8

We cancel out to obtain:

7x +  2 \times 3 =  - 6 \times 8

We simplify to obtain:

7x +  6 =  - 48
