If a 42.9 ft tall flagpole casts a 253.1 ft long shadow then how long is the shadow that a 6.2 ft tall woman casts?
blsea [12.9K]
We will have to use proportions:
\frac{42.9}{253.1}  =  \frac{6.2}{x}
Cross multiplying we get
42.9x = 6.2 \times 253.1
Now divide:
x =  \frac{6.2 \times 253.1}{42.9}
Solve to tenths place we get
x = 36.6
The woman casts a 36.6 ft long shadow.

dem82 [27]

Answer:

D

Step-by-step explanation:

The answer is point D(-2,1).

1. If the point D was moved down 2 units, then its coordinates became (-2,-1).

2. If point (-2,-1) was reflected over the x-axis, then its coordinates became (-2,1).

3. If the point (-2,1) was moved 4 units to the right, then its coordinates became (2,1).

4. If point (2,1) was reflected over y-axis, its coordinates became (-2,1).
