erik [133]3 years ago
5 0

Answer:

Step-by-step explanation:

1. 10² + 7² = x²

 149 = x²

 x = √149

2. x² + 19² = 21²

 x² = 21² -  19² = 80

 x = √80 = 4√5

3. x² + 16² = 27²

 x² = 27² - 16² = 473

 x = √473

4. 5.3² + 12.8² = x²

 191.93 = x²

 x = √191.93

5. 9² + 20² = x²

 481 = x²

 x = √481

6. 31 = x + 2√(19²-17²) = x + 2·6√2 = x + 12√2

 x = 31 - 12√2

inysia [295]

Answer:

9.1 gallons of water.

Step-by-step explanation:

A standard showerhead dispenses 21 gallons of water in 30 mins. At this rate, how many gallons of water will a standard showerhead dispenses in 13 minutes?

30 minutes = 21 gallons

13 minutes = x gallons

Cross Multiply

30 minutes × x = 13 minutes × 21 gallons

x = 13 minutes × 21 gallons/30 minutes

x = 9.1 gallons of water

Therefore, a standard showerhead dispenses 9.1 gallons of water in 13 minutes.

On a 4 1 2 hour trip, Leslie drove 2 3 of the time. For how many hours did Leslie drive?
valentina_108 [34]

Answer:

She drove 3 hours

Step-by-step explanation:

Leslie drove 2/3 of the 4 1/2 hours trip.  To determine how long she drove, multiply these numbers together.

2/3 * 4 1/2

We need to change the second number to an improper fraction

4 1/2 = (2*4 +1)/2 = 9/2


2/3 * 9/2 = 9/3 = 3


She drove 3 hours
