Answers

$-3(1)/(3):9=-(10)/(3):9=-(10)/(3)\cdot(1)/(9)=-(10\cdot1)/(3\cdot9)=-(10)/(27)\n\nAnswer:A$

-3 1/3 divide 9

9 can be written as 9/1

use the method keep change flip

-10/3 * 1/9 = -10/27

remember negative times positive equals negative.

Answer: A.-10/27

A boat traveled 504 miles downstream and back. The trip downstream took 14 hours. The trip back took 21 hours. What is the speed of the boat in still water? What is the speed of the current?

Answers

The speed of the boat in still water will be 30 miles per hour and the speed of the current will be 6 miles per hour.

What is the solution to the equation?

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

Let the speed of the boat in still water be x and the speed of water be y.

A boat traveled 504 miles downstream and back. The trip downstream took 14 hours. Then the equation will be

x + y = 504 / 14

x + y = 36 ...1

The trip back took 21 hours. Then the equation will be

x - y = 504 / 21

x - y = 24 ...2

Add equations 1 and 2, then the value of x will be

2x = 36 + 24

2x = 60

x = 30 miles per hour

Then the value of y will be

30 - y = 24

y = 6 miles per hour

The speed of the boat in still water will be 30 miles per hour and the speed of the current will be 6 miles per hour.

Answer:

The speed of the boat in still water is 30 mph, and the speed of the current is 6 mph.

Step-by-step explanation:

Let's say b is the speed of the boat in still water, and c is the speed of the current.

Distance = rate × time

Going downstream:

504 = (b + c) × 14

36 = b + c

Going upstream:

504 = (b − c) × 21

24 = b − c

Two equations, two variables. Solve with substitution or elimination. To use elimination, add the equations together.

60 = 2b

b = 30

Plug into any equation to find c.

36 = b + c

36 = 30 + c

c = 6

The speed of the boat in still water is 30 mph, and the speed of the current is 6 mph.
