Answer:

I got 43

Step-by-step explanation:

The first step I took was to make a proportion. I did 9/21 equals x/100. The whole is 21 because it says "Hint: How many players did Clayton play/" so I am guessing it means adding 9 and 12. Then I divided 900 by 21 after using what you would call the butterfly method. I rounded 42.85... to 43.

I hope this helps. This is how I remember it and I got the correct answer. Good luck!

Value of p in equation 3/5p(1+5/3)=3 1/2

Lady_Fox [76]

3/5p(1+5/3)=3 1/2
3/5p(1) + 3/5p*5/3 = 3 1/2
3/5p + p = 3 1/2
3/5p + 5/5*p = 3 1/2
8/5p = 3 1/2
now multiply both sides by 5/8 (to get p by itself) which gives:
p = 5/8 * 3 1/2 = 5/8 * 7/2 = 35/16

The ratio of white flour to whole wheat flour in a bread recipe is 2:3. The recipe uses 60 cups of flour. How much white flour i

luda_lava [24]

So white flour to whole wheat is 2:3, and wheat flour is 60 cups.

Lets put it this way, 2 white flour = 3 wheat flour
If we have 60 cups of wheat flour, we are multiplying the above equation by 20 to get 3 x 20 - 60 cups of wheat flour.

2 white flour = 3 wheat flour (times 20 is 60, which is what they're asking)

Now we need to multiply 20 on both sides, because what you do on one side must be done to the other.

2 white flour = 3 wheat flour
x 20 x 20

40 white flour = 60 wheat flour

The final answer should be 40 cups of white flour is needed when the recipe uses 60 cups of wheat flour.

Hope this helps! :)

If interest is compounded every 3 months, how often is it compounded?

Mamont248 [21]

Answer:

c. quarterly

Step-by-step explanation:

To start with 1 year is equal to twelve months

3months out of 12 months will be;

3/12= 1/4

Here it is compounded quarterly and n=4 where n is the number of compoundings a year.

Lets study the compound interest formula;

$A=P(1+\frac{r}{n} )^{nt}$

where;

A=The ending amount

P=Starting amount

r=rate of interest expressed as a decimal

n=number of compoundings a year

t=total number of years

The number of compoundings in any one year can be an interest compounded yearly where n=1, semi-annually with n=2, quarterly where n=4, monthly where n=12, weekly and n=52 and finaly daily with n=365.
