Answer:
p=59.19°
Step-by-step explanation:
We first find the length BD
BD=√(6²+5²)=√61
Using Pythagorean theorem,we find p by:
cos(p°)=4/√61
p=cos^-1(4/√61)
p=59.19°
Cost per ounce means you take the cost and divide it by the cost:
<span>3.36 / (21/2) </span>
<span>division of fractions changes to the multiplication of the reciprocal: </span>
<span>3.36 * (2 / 21) </span>
<span>3.36 and has 21 as a factor, so let's cancel it: </span>
<span>0.16 * 2 </span>
<span>$0.32 per ounce</span>
Answer:
Look at the number line.
Step-by-step explanation:
Step 1: Draw a number line.
Step 2: Mark -4 on the number line.
Step 3: Here we have to subtract 8, therefore, from -4 move 8 units left, we end up at -12.
That is the answer. Here is the picture.
