Answer:40 bushels of seed would be required to plant 30 acres of wheat.
Step-by-step explanation:
On the average, 1 1/3 bushels of seed are needed to plant 1 acre of wheat. Converting 1 1/3 bushels of seed to improper fraction, it becomes 4/3 bushels of seed.
Let x represent the bushels of seed that would be required to plant 30 acres. Therefore
4/3 bushels of seed = 1 acre
x = 30 acres
Cross multiplying
x × 1 = 4/3 × 30
x = 40 bushels of seed
Answer:
15 ways.
Step-by-step explanation:
There are 5 ways to have 1 topping.
There are 5C2 = 5*4 / 2*1 = 10 ways of having 2 toppings.
A secured credit is secured by something else. An example is that a home mortgage is secured by the home.
Answer:
First, two lines are perpendicular if one has slope m, and the other has slope -1/m (Not 1m as Alan says)
That is the first error of Alan.
Now, there is another error.
If m = 0, then -1/m tends to minus infinity (in this case we would have a vertical line).
But we can not really divide by zero, so we should state that:
m can not be zero, if a line is horizontal, the perpendicular line must be vertical.
