Answer:
1/36
Step-by-step explanation:
(-6) ^-2
The negative in the exponent means in goes from the numerator to the denominator
(-6) ^-2 = 1/ (-6)^2
We know that
(-6)^2 = -6*-6 = 36
(-6) ^-2 = 1/ 36
X = 7
8(7) = 5(7) + 21
56 = 35 + 21
56 = 56
A fraction is just a short way to WRITE a division problem. It means "the top number divided by the bottom number". Take the two numbers from the fraction, DO the division, and you get the decimal.
To isolate b, add a and subtract c to the entire equation:
D - a + c = -b
Muliply b by -1 to eliminate the negative:
-D + a - c = b
Answer:
51 meters
Step-by-step explanation:
Steve is turning half his backyard into a chicken fan. His backyard is a 24 m x 45 m rectangle. He wants to put a chicken wire fence that stretches diagonally from one corner to the opposite corner. How many meters of fencing will Steve need?
We are to find the meters of fencing for the diagonal.
We solve the question using Pythagoras Theorem
= c² = a² + b²
Where
c = Diagonal
a = Width
b =Length
Diagonal² = Width² + Length ²
Hence:
Diagonal ² = 45² + 24²
Diagonal = √45² + 24²
Diagonal = √(2601)
Diagonal = 51 m
Therefore, the meters of fencing for the diagonal that Steve would be needing = 51 meters
