If 3 of the pennies are Canadian, then the other 12-3=9 pennies are not Canadian.  Therefore, the desired probability is 9/12, which is equal to 3/4.  B is the correct answer.

All of Ralph’s ranch land was divided equally among his six children whose daughter land portion of the ranch land was divided a
Nitella [24]

Answer: 1/24 of Ralph's land

Step-by-step explanation:

Ralph gave each of his children a 6th of his land.

= 1/6

Lynn being his daughter got 1/6 of his land. She then shared it to her 4 children.

Children got 1/4 of Lynn's land which is 1/6 of Ralph's land.

Lynn's children therefore got;

= 1/4 * 1/6

= 1/24 of the land

How are percents greater than 100% used in real world contexts
docker41 [41]

Answer:

Think of investments. If you were to invest $100 into a company and receive $200 dollars, then you would have made $100 in profit, which is 100% of your initial amount. So, if you were to invest $100 and receive $250 dollars in profit, then you would have made an extra $150, which is even more than your initial amount of $100. In this case, you would have made a 150% increase on your money.

Find all real solutions of the equation by factoring. x2 = 5(x + 210)
anzhelika [568]

The real solution of the given equation by factoring x² = 5(x + 210) will be -30 and 35.

<h3>What are the roots of an equation?</h3>

The roots of an equation are the solution of that equation since an equation consists of hidden values of the variable to determine them by different processes and then the resultant is called roots.

As per the given equation,

x² = 5(x + 210)

x² = 5x + 1050

x² - 5x - 1050 = 0

x² - 35x + 30x - 1050 = 0

x(x - 35) + 30(x - 35) = 0

(x + 30)(x - 35) = 0

x = -30 and x = 35

Hence "The real solution of the given equation by factoring x² = 5(x + 210) will be -30 and 35".
