My late response (haha): First, you would write a proportion.
Step 1: 2496 over 48 = x over 31
(x represents the area of the land that is not fenced).
Step 2: Cross multiply
2496 times 31 and x times 48
Step 3: Calculate
77376 = 48x
Step 4: Divide both sides by 48
77376/48 = 1612
48x/48 = x
Step 5: Write it as a sentence
The area of the land that is not fenced is 1612 squared meters.
Hope that helped! Good luck! :]
Answer:
x= -9......................
The perimeter of a semicircle consists of two parts. (the curve and bottom)
That curve is half the distance around the circle, since it's been split in half.
The distance around a circle, the circumfrence, is equal to 2πr, where r is the radius of that circle. In this case, the circumfrence of the entire circle would be 16π. and so that curve would have a length of just 8π.
Using 3.14 for π, 8π = 8×3.14 = 25.12.
As for the flat part, that is the diameter (distance across) our circle.
The radius is the distance from the center of a circle to its edge, and always has half the length of the diameter. (you can break the diameter down into two radii)
If our radius is 8 meters, our diameter (the flat part of that semicircle) must be 16.
Now we add up the two parts of the perimeter...25.12 + 16 = 41.12.
Answer:
A
Step-by-step explanation:
0.732
0.750
If you have trouble with decimals, then multiply both numbers by a constant number to get rid of the decimals. In this case, we would multiply by 1000.
0.732 x 1000 = 732
0.750 x 1000 = 750
Obviously, 750 is bigger than 732. Therefore, 0.75 is bigger than 7.32.
By the way, this is a property:
If
