A man (M) is standing on the bank of a river that is 0.9 miles wide. He wants to reach a house (B) on the opposite shore that is

0.9 miles downstream. The man can row the boat 3 mph and can walk 4.5mph. Find the distance between the house and the point (P) where he should dock his boat in order to minimize the total time he would need to reach the house. Enter the exact answer or round to the nearest hundredth.

Answer:

The distance between the hose and the point (P) is 0.9 miles

Step-by-step explanation:

Here we have

Speed of rowing the boat = 3 mph

Speed of waling = 4.5 mph

Since the speed of walking is more than that of to row the  boat, the location of where he should dock his boat in order to minimize the total time he would need to reach the house is the shortest distance across the river to the house

Therefore the location of the point (P) should be directly opposite the house across the water and the distance id 0.9 miles.

Help with this please
valkas [14]

Answer:

  a) cannot be determined

  b) a triangle can be drawn, but its dimensions cannot be determined

Step-by-step explanation:

<h3>a)</h3>

The vertical axis is labeled in units of kilometers. The horizontal axis is labeled as distance, with no units given. The line shown appears to descend from 12 units above ground level over a distance of 34 units along ground level. One could argue the slope is 12/34 = 6/17, but there is no indication the horizontal units are the same as the vertical units.

The slope of the graph cannot be determined, because we don't know the horizontal units.

__

<h3>b)</h3>

You can draw the triangle, but you cannot determine its dimensions.

Find the length of a picture frame whose width is 3 inches and whose proportions are the same as a 9-inch wide by 12-inch long p
barxatty [35]

Answer:

4 inches

Step-by-step explanation:

We can set up a proportion to find out the length value (assuming x is the length of the frame)

\frac{3}{x} = \frac{9}{12}

We multiply 12 and 3...

12\cdot3=36

And divide by 9...

36\div9=4

So, the length of the frame is 4 inches.

Hope this helped!

Sixty miles per hour is how many feet per second
dybincka [34]
5280 feet = 1 mile

5280 × 60 = 316800

316800 feet per hour

3600 seconds = 1 hour

316800 feet per 3600 seconds

316800 ÷ 3600 = 88

88 feet per second
