180 degrees is half of a circle, and clockwise means turning in the direction a clock does - right.

So a point would be turned right halfway around.

A shop sells newspapers for a profit of 0.5%. His sales for the month of January were $8341.50. How much of this is profit?

Doss [256]

Amount of sales of newspapers for the month of January = $8341.50
Percentage of profit for which the newspaper is sold = 0.5%
Then
Amount of profit made in the month of January = 0.5% * 8341.50 dollars
   = (0.5/100) * 8341.50 dollars
   = 4170.75/100 dollars
   = 41.707 dollars
   = 41.71 dollars
So the shop makes a profit of $41.71 in the month of January by selling newspapers worth $8341.50. I hope the procedure is perfectly clear for you to understand.

A 20-foot ladder leans up against the side of a building so that the foot of the ladder is 10 feet from the base of the building

harina [27]

Answer:

17.3

Step-by-step explanation:

To solve this equation, you need to use the pythagorean theorem which is:

$a^{2} +b^{2}= c^{2}$

a= length

b= height

c= hypotenuse

First, substitute in your values for the equation:

$10^2+b^{2} =20^{2}$

Then, use the squares in the equation:

$100+b^{2} =400$

Then, subtract 100 from both sides to isolate b:

$b^{2} =300$

Finally, square root both sides to get your answer:

$b=17.3205080757$

Then round to the nearest tenth which gives you 17.3.
