6 0

Answer:

AC=15.9976

Step-by-step explanation:

Law of Sines: \frac{sin(A)}{a} =\frac{sin(B)}{b} =\frac{sin(C)}{c}

Step 1: Define

a = 8 ft

A = 30°

b = ?

B = 89°

Step 2: Substitute and Evaluate

\frac{sin(30)}{8} =\frac{sin(89)}{b}

bsin(30)=8sin(89)

b=\frac{8sin(89)}{sin(30)}

b=16cos(1)

b=15.9976

AC=15.9976

grade 5 math. How would I write a ratio for a project when asked to compare prices from two stores, IE 32 slices of texas toast
REY [17]
To compare, think of the ratios as a fraction. so it is 32 slices per $7.99.
You can also say $7.99 per 32 slices.
so it can be  ̲7̲.̲9̲9̲ ̲   or the other way around.
                       32
To find the unit price, or the price of 1 item, you have to divide the price by the amount.
So 7.99 divided by 32 is <span>0.249687, but we don't have thousandths of a cent, so we round to the hundredth.
$0.25 is the unit price, or the price of 1 toast, rounded to the nearest cent.

So let's try another one, this time we have 2 different rates, and we will compare them.

So let's say we are buying cheese. Store A sells 12 blocks of cheese for $14.99, and Store B sells 20 blocks for $23.99.
So first we have to find the unit rate for each.

             Store A                                 Store B
         14.99 per 12                        23.99 per 20
                                         
             </span> ̲1̲4̲.̲9̲9̲ ̲                                  ̲2̲3̲.̲9̲9̲ ̲<span>
                 12                                         20

14.99 / 12 is </span>1.24916                    23.99 / 20 is <span>1.1995</span>
<span>$1.25, if rounded to the cent.    $1.20, if rounded to the cent
</span>1 block is $1.25 in Store A.         1 block is $1.20 in Store B

Store B sells for cheaper.

Hope that helps.
