Answer:
78 is 7 divided by 8, which equals 0.875. So an equivalent fraction is another fraction that also equals 0.875.
Basically, every zero a number has to the end, the higher the scientific notation will be. Because 1000 has three zeroes, 10^5 will go to 10^8. So, you will travel 7.5 x 10^8 miles.
The top half is called the numerator.
The bottom is called the denominator.
The answer is 17
4x3=12
3x2=6
12+6=18
18-1=17
The greatest area he can fence is 64 ft².
In order to maximize area and minimize perimeter, we use dimensions that are as close to equivalent as possible. 32 feet of fence for 4 sides gives us 8 feet of fence per side. We would have a square whose side length is 8; the area would be 8*8 = 64.
