Answer:
<h3>1/1024=0.0009765625</h3>
Step-by-step explanation:
To solve this problem, first, you have to use the order of operations stands for (Parenthesis, Exponents, Multiply, Divide, Add, and Subtract) left to right. Please Excuse My Dear Aunt Sally!
4⁻⁵
4⁻⁵ (First, do exponent.)
4⁻⁵= 4⁵
1/4⁵
4⁵ (Solve.)
4⁵=4*4*4*4*4=1024
1/1024=0.0009765625
1/1024=0.0009765625
As a result, the correct answer is 1/1024=0.0009765625.

Answer:
$7.09
Step-by-step explanation:
Let wheat shipment be x bushels
Per bushel cost = 5.35
So x bushels cost = 5.35x
Achieving markup of 6% means 1.06 * 5.35x =5.671x
20% spoiled means 80% of x stays, so 0.8x will need to be sold at 5.671x
Selling price should be 5.671x/0.8x = $7.09
So that's 7 dollars and 9 cents
You calculate it by taking the change in y's over the change in x's. So (y1-y2)/(x1-x2). You get the equation (-5 - 3)/(5 - 7) which equals 4. 4 is the slope.
