Answer:

<h2>11.125</h2>

Step-by-step explanation:

10  +  {(2 \times 3)}^{2}   \div 4 \times  {( \frac{1}{2}) }^{3}

To raise a product to a power, raise each factor to that power

= 10 + 4 \times 9 \div 4 \times  {( \frac{1}{2} )}^{3}

To raise a fraction to a power, raise the numerator and denominator to that power

= 10 + 4 \times 9 \div 4 \times  \frac{1}{8}

Any expression divided by itself equals 1

= 10 + 1 \times 9 \times \frac{1}{8}

Any expression multiplied by 1 remains the same

= 10 + 9 \times  \frac{1}{8}

Calculate the product

= 10 +  \frac{9}{8}

Write all numerators above the common denominator

=  \frac{80 + 9}{8}

Add the numbers

=  \frac{89}{8}

Divide

= 11.125

Hope this helps..

Best regards!!

Khianna wants to make a batch of her Grandma chocolate chip cookies from a friend. The recipe is shown on the recipe card below
Mademuasel [1]
She has 9/8 cups of brown sugar as a fraction.  As a decimal, which is easier to work with here, it is 1.125.  She needs 1.5 cups.  If we set this up as a proportion, we can figure out how many cookies she can make meeting the restriction of brown sugar, and then scale the other ingredients down accordingly.  To figure the number of cookies, our proportion will have brown sugar on top and number of cookies on bottom.  What we are looking for is the number of cookies she can make with 1.125 cups of brown sugar when she can make 24 with 1.5 cups of brown sugar.  \frac{1.5}{24}= \frac{1.125}{x}.  Cross multiply to get 1.5x = 27 and x = 18.  She can make 18 cookies.  Now let's backtrack to the ingredients based on the number of cookies we can make.  Set each ingredient up in a proportion with the ingredient on top and the number of cookies on the bottom.  First ingredient you want is flour.  2.25 cups of flour make 24 cookies and we need to find out how much flour will we need to make 18 cookies.  \frac{2.25}{24}= \frac{x}{18}.  Cross multiply to get 24x = 40.5 which simplifies to x = 27/16 or 1 11/16 cups of flour.  Do all the ingredients in the same way and you'll be fine!

Jacki plans to pay for the down payment of a new car with her credit card. The annual interest rate for her credit card is 17%.

very interesting

the equation we are given is for when the units of t are in years

I do know that you want to have the variable as time, but I'm not sure if you want it in years or months

I will solve for in months because that makes more sense

in that case, it will be 2250(1+r)^m where r=monthly interest rate and m=time in months

to compare, we can do

when 1 year has elapsed, t=1 and m=12

and the amount earned should be the same

so therfor we can say

2250(1.17)^1=2250(1+r)^{12}

divide both sides by 2250 to make it easier

1.17^1=(1+r)^{12}

1.17=(1+r)^{12}

take 12th root of both sides

\sqrt[12]{1.17}=1+r

minus 1 both sides

-1+\sqrt[12]{1.17}=r

using a calculator

-1+1.01316961=r

<span>0.01316961=r</span>

<span>not sure if yu want percent to thousandth or decimal to thousandth</span>

<span>if decimal then 0.013 is interest rate</span>

<span>if percent then it is 1.317% interest rate</span>
