Step-by-step explanation:
7 x 40 = 280 + C = 380
C = Commision

C = 100
The directrix of the parabola is 
<h3>How to determine the equation of the directrix?</h3>
The parabola equation is given as:
A parabola is represented as:
By comparing both equations, we have:
4p = 1/4 ==> p = 1/16
-k= 3 ==> k = -3
The directrix is represented as:
y = k - p
So, we have:
Take the LCM
Evaluate
Hence, the directrix of the parabola is

First we need to make both fractions equal to each other, and that means having to have the denominators the same.
What both 3 and 12 easily go into is 12.
So we need to make both fractions have a denominator of 12, so we multiply.
2/3 * 4/4 = 8 / 12
1/4 * 3/3 = 3 / 12
Now, we know that she has 8 / 12 pounds, and she uses 3 / 12 of it, so now we subtract to find how much she has left.
8 - 3 = 5
Out of the 12 pounds of roast beef, she now has 5 / 12 left.
Answer:
Step-by-step explanation:
y ÷ 3(4 - 2) + 5.5
= y ÷ 3(2) + 5.5
= y ÷ 6 + 5.5
= y/6 + 5.5
= (y + 33)/6
You have to multiple b× w×h. the answer would be 342
