1 cup makes 12
2.5 cups make (12x2.5) = 30 muffins

30 muffins.

12 muffins for every 1 cup. 6 muffins for every 1/2 cup. So, 2 cups= 24 muffins and 24+6=30.

What is the quotient of the following division problem (x+ 1)÷(x^2 + 3x +2)
seraphim [82]

Note: Actually, the division problem should be in reverse order. It should be given as (x^{2} +3x+2) / (x+1) ---------(i)

But according to the given problem (x + 1) / (x² + 3 x + 2).

Here, (x² + 3 x + 2) > (x + 1)

or, (x + 2) > 1

Concept: By using the property of division, if the numerator is less than the denominator then the quotient will always be 0 (zero)

Therefore the option (d) 0 will be the correct option.

In a certain state, there are currently 5,902,060 acres of farmland. This area is decreasing at a rate of 4.3% every year. Selec
Luba_88 [7]

Answer:

y=5,902,060*(.957)^t

Step-by-step explanation:

Since the original amount would be decreasing and it's an exponential one, hence the "every year", we can determine that it's an exponential decay equation.

The exponential delay equation is y=A*(1-r)^t. The y is the remaining amount, A is the original amount, r is the rate in decimal form, and t is for years. "1-r" is for decreasing rates and "1+r" is for increasing rates.

First thing we need to do is turn the rate, 4.3%, from a percentage to a decimal. You can do this by moving the decimal two places to the right, which gives you 0.043.

Now plug the numbers into the equation.

y=5,902,060*(1-0.043)^t

Simplify what's inside the parenthesis and get your final equation.

y=5,902,060*(.957)^t
