You would do 20 • 3=60 and the you would add 20 • 1/5=4 so, your total is 64in.

Tinh can row at a rate of 6 mph in still water. It takes her 2 hours to row upstream from a dock to a park. She then rows back t

scZoUnD [109]

Answer:

Option A is correct, i.e. 3 mph.

Step-by-step explanation:

Tinh can row at a rate of 6 mph in still water.

Suppose the speed of the river current is X mph.

Then Upstream speed = (6-X) mph.

And Downstream speed = (6+X) mph.

It takes her 2 hours to row upstream from a dock to a park. She then rows back to the dock, and it only takes 40 minutes.

It means Distance upstream = Distance downstream.

Speed upstream x Time upstream = Speed downstream x Time downstream.

(6-x) * 2 = (6+x) * 40/60

12 - 2x = 4 + 2x/3

12 - 4 = 2x/3 + 2x

8 = 2x/3 + 6x/3 = 8x/3

x = 3 mph.

Hence, option A is correct, i.e. 3 mph.

6 tenths or 6/10

it doesn't matter how many zeros you have after the .6 it's still 6 tenths. It can have a hundred zeros it will still be just .6 = 6/10 = 6 tenths

Hope that helps you. :-)

The men s clothing buyer had a group of 50 jackets priced at $250 each that was selling very slowly. To stimulate sales of these

erastovalidia [21]

Answer:

The answer is $3000.

Step-by-step explanation:

The men's clothing buyer had a group of 50 jackets priced at $250 each.

Total price of jackets = $50\times250=12500$ dollars

The buyer reduced the price of the jackets in that group to $200 and 40 jackets were sold.

So, the price for selling 40 jackets is = $40\times200=8000$ dollars

Remaining jackets = $50-40=10$

These were sold at $150 each, totaling to = $10\times150=1500$ dollars

So, overall money earned by reducing prices both time = $8000+1500=9500$ dollars

And the markdown in dollars = (original price before reducing) minus (educed total price)

= $12500-9500=3000$ dollars

So, the answer is $3000.

The three missing lengths are the left hypotenuse, x, the middle altitude, y, and the right hypotenuse, z.

9/y = y/16

y^2 = 9 * 16

y^2 = 144

y = 12

9^2 + 12^2 = x^2

x^2 = 225

x = 15

12^2 + 16^2 = z^2

z^2 = 400

z = 20

From left to right, the sides measure 15, 12, and 20 units.
