The first thing we must do for this case is find the factors of each of the numbers.
We have then:
60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Therefore the GCF is given by:
So, by rewriting the sum we have:
The error is not having written the GCF multiplying.
Answer:
Xiao did not write the sum as the product of GCF and the sum of two numbers.
The correct expression is:
Answer:
40 ft × 75 ft
Step-by-step explanation:
Let x be the one side ( in feet ) of the rectangular parcel,
So, the diagonal between opposite corners = ( x + 10 ) feet,
Let y be the other side of the rectangle ( adjacent to side x ),
The area of the rectangle,
A = x × y,
According to the question,
A = 3000 square ft,
∵ In a rectangle,
Where, a and b are the adjacent side of the rectangle and D is the diagonal,
By graphing the equation,
We found that,
The only real zeros of the equation is at x = 75,
Hence, the one side of the rectangle = 75 ft,
And, second side = = 40 ft
Hence, the dimension of the land is 40 ft × 75 ft
Answer:
model:
profit in year 2017:
Step-by-step explanation:
The sales increased from 2 billion dollars to 146 billion dollars in five years, so to find the increase in billion dollars per year, we just need to divide the increase by the amount of time:
To construct a model for these sales, we can use the year 2003 as the initial point of a linear equation:
the variable y will represent the profit in billion dollars, the variable x will represent our time, so we can use (t - 2003) in its place to represent the number of years since 2003 (t is the year we want to calculate), the constant 'a' will be our rate of 28.8, and the constant 'b' is the inicial value for the year 2003, that is, 2 (billions). So we have:
In the year 2017, we would have:
