Answer:
(B) The inequality that represents this relationship is 
Step-by-step explanation:
Let us assume the given number = x
⇒ 3 times the given number = 3 (x) = 3x
Square of the given number = 
Now, According to the question:
The difference of (3 x) and 15 is no less than 
⇒ 
or, 
Hence, the given inequality is represented as 
The answer is $24.41
Step 1. Calculate the area of the <span>circular piece of fabric.
Step 2. Multiply the area of the piece by the price of </span><span>$5.40 per ft² to get the total cost.
Step 1.
The area (A) of the circle with radius r is:
A = </span>π r²
π = 3.14
r = 1.2 ft
A = 3.14 * (1.2 ft)²
A = 3.14 * 1.44 ft²
A = 4.52 ft²
Step 2.
Make a proportion
1 ft² costs $5.40
4.52 ft² cost x
1 ft² : $5.40 = 4.52 ft² : x
x = 4.52 ft² * $5.40 / 1 ft²
x = $24.41
You would take the square root of x^2 and of 121 so x =11
Answer:
25.9
Step-by-step explanation:
25.9
pi-pi+pi/pi is 0+(1*25.9) which is 25.9
