7 pancakes = 1.5 cups
35/7= 5
1.5 x 5 = 7.5

Answer:

7 1/2 cups of mix

Step-by-step explanation:

This looks like a question involving <em>proportions</em>, so I'm going to set up some proportions to help us find the correct answer:

$\frac{1\frac{1}{2} }{7} =\frac{x}{35}$

What I immediately notice is that I can multiply the 7 on the denominator of the first proportion by 5 to get to the denominator of the second proportion, which is 35.

So, I can multiply 1 1/2 (or 3/2) by 5 to find the value of x:

$\frac{3}{2} *\frac{5}{1} =\frac{15}{2} =7\frac{1}{2}$

So, the answer is 7 1/2 cups of mix. Hopefully that's helpful! :)

Answer:

The value of the account in the year 2009 will be $682.

Step-by-step explanation:

The acount's balance, in t years after 1999, can be modeled by the following equation.

$A(t) = Pe^{rt}$

In which A(t) is the amount after t years, P is the initial money deposited, and r is the rate of interest.

$330 in an account in the year 1999

This means that $P = 330$

$590 in the year 2007

2007 is 8 years after 1999, so P(8) = 590.

We use this to find r.

$A(t) = Pe^{rt}$

$590 = 330e^{8r}$

$e^{8r} = \frac{590}{330}$

$e^{8r} = 1.79$

Applying ln to both sides:

$\ln{e^{8r}} = \ln{1.79}$

$8r = \ln{1.79}$

$r = \frac{\ln{1.79}}{8}$

$r = 0.0726$

Determine the value of the account, to the nearest dollar, in the year 2009.

2009 is 10 years after 1999, so this is A(10).

$A(t) = 330e^{0.0726t}$

$A(10) = 330e^{0.0726*10} = 682$

The value of the account in the year 2009 will be $682.
