     The area of the circular shaped rug would be 451.931, let me explain to you how I got this calculation.
     
     First thing you have to do is know the formula to find the area of a circle. The formula is A=pie x Rsquared, but when you look at the information provided, you dont have the radius, so you have to find it yourself. 
 
    You probably noticed that since diameter is twice the radius, the proportion between circumference and diameter is equal to π: <span>C/D = 2πR / 2R = π is the formula for the convertion of circumfrence to diameter.
</span> 
     Once you find the diameter, which should be rounded to 23.98, you will need to divide it by 2 for the radius which should give you approximatly 11.99. 
 
     Finally, you do the regular formula to find area which is A=pie x Rsquared. so you do 3.14 x (11.99 x 11.99)=451.931in.

The sum of two numbers is 15. Twice one number equals 3 times the other. Find both numbers
Dmitrij [34]

Answer:

9 & 6

Step-by-step explanation:

First, check if, by adding them (sum), they equal 15:

9 + 6 = 15

Next, check the greater number, by multiplying it by 2:

9 x 2 = 18

Check the lesser number, by multiplying it by 3:

6 x 3 = 18

Note that they both have 18 as an answer.

9 & 6 are your answers.

I’m stuck please help ? Due tomorrow

Here are two ways of doing it.

************************************************************

1) The current price is 100% of the price. The price went down by 6%, so since 100% - 6% = 94%, the new price is 94% of the original price.

94% * 175 = 0.94 * 175 = 164.50

The new price is 164.50

*******************************************************

2) The discount is 6% of 175, so first, we find the discount.

6% of 175 = 0.06 * 175 = 10.5

Now we subtract the amount of the discount from the original price.

175 - 10.50 = 164.50

The new price is 164.50

**********************************************************

As you can see, both methods give you the same answer, 164.50

Anybody know the answer?
expeople1 [14]
Y=x-2+3
I put x-2 because when graphing it's the opposite so it would technically be x+2
Then the +3 for the y chords which go up by 3 ! if this is wrong then try Y= (x-2)+3
