Answer:

approximate speed would be 19 revolutions per minute.

Step-by-step explanation:

For model 5, blade length = 148 feet

Maximum blade tip speed = 200 miles per hour

tip of the blade travels per revolution = 0.18 mile

Number of revolutions per hour = \frac{200}{0.18} = 1,111

To get speed per minute, divide by 1 minute ( 60 seconds ).

\frac{1,111}{60} = 18.51 ≈ 19 revolutions per minute.

This question is incomplete

Complete Question

A scientist poured 1.6 x 10³ milliliters of water into a container that already had 2.8 x 10⁴ milliliters of salt water and 9.4 x 10³ milliliters of sugar water. How many milliliters of liquid were in the container?

A.1.7 x 10⁴ milliliters

B.3.58 x 10⁴ milliliters

C.3.74 x 10⁴ milliliters

D.3.9 x 10⁴ milliliters

Answer:

C. 3.74 x 10⁴ milliliters

Step-by-step explanation:

The milliliters of liquid that WERE in the container = The milliliters of liquid that were in the container before adding 1.6 x 10³ milliliters of water

This equals to:

2.8 x 10⁴ milliliters of salt water and 9.4 x 10³ milliliters of sugar water.

Hence:

2.8 x 10⁴ milliliters of salt water + 9.4 x 10³ milliliters of sugar water

= (2.8 × 10⁴) + (9.4 × 10³)

= 37400

= 3.74 x 10⁴ milliliters

Therefore, option C is correct
