Answer:
Each board is (4/25) meters long = 0.16 meters long
Step-by-step explanation:
The board is 4/5 meters long, and he needs to cut 5 equal pieces, so we need to divide 4/5 of a meter in 5 parts.
This mathematically becomes: 4/5 divided by 5 which by the definition of division of rational numbers, is the same as :
4/5 times the reciprocal of 5 = (4/5) * (1/5) = (4/25) = 0.16 meters each board
Answer:
-10
Step-by-step explanation:
Pascal’s triangle: It represents the binomial coefficients. If a binomial expression is (a+b)^n, then (n+1)th row of Pascal’s triangle represents the binomial coefficients or that binomial expression.
The given binomial expression is
The elements of 6th row are 1, 5, 10, 10, 5 and 1.
Therefore, the coefficient of x²y³ is -10.
Answer:
