Answer:
Meanings of the numbers:
Most numbers represent an amount. Positive numbers represent above zero. Zero is the only number that does not represent an amount. It means nothing. When you go lower than nothing, you are in the negative numbers. Negative numbers represent absent values pretty much.
How I would use them in every day life:
I would use positive numbers to represent... maybe something I'm trying to get at a store. Ex: 4 bananas
I would use negative numbers to... maybe look at the temperature. Ex: -16 degrees Fahrenheit. Negative numbers are in temperature all the time.
Hope this helps! (^-^)
Answer:
distance covered in 2 hours = 80 km
distance covered in 1 hour = 80÷2 = 40 km
distance covered in 7/2 hours = 40 × 7/2
= 140 km
(3 1/2hours = 7/2 hours)

Answer:
1) b⁵⁴
2) 7⁷
Step-by-step explanation:
When you have an exponent raised to an exponent, like in #1, you simply multiply the exponents.
When you are dividing two numbers with exponents and they have the same base, like in #2, you subtract the denominator exponent from the numerator exponent.
The perimeter without the diagonal is 4*120 = 480
That covers the outside of the field
The diagonal is 120 *
= 169.7 yd
480 + 169.7 = 649.7 yd total of fencing
