Answer:
He did 9 times 10 instead of 9 times 100.
Answer: The answer is 43.
Step-by-step explanation: Given that there is a quart, in which there are 946 millilitres and 22 pints. We are to find how many millilitres are there in a pint.
For that, we just need to divide number of milliliters by the number of pints in the quart.
Let us start as follows -
In 22 pints of the quart = 946 millilitres.
Therefore, in 1 pint of the quart = 946/22 = 43 millilitres.
First, let x be the number of hours it will take for Hector to finish the same job alone. This means that every hour, Hector can do 1/x of the job. The amount of work done by Shawn and Hector in 6 hours should be equal to 1 complete work. This can be expressed as,
(1/9 + 1/x)(6) = 1
The value of x is 18. Thus, Hector can to 1/18 of the job in one hour.
In polynomials, when a term contains both a number and a variable part, the number is called the co-efficient.
In this problem the co-efficient of x =
(8+y)+(3x+y2)
3y+3x+8
Therefore the co efficient of x and y is 3
parallel: g(x) = -5/3x + 1
perpendicular: h(x) = 3/5x - 5
neither: j(x) = 2x + 3
