Answer:
9/10
Step-by-step explanation:
In ratio units, the relative lengths of the first, second, and third towels are ...
... 1 : 3/5 : (5/12)·(1 +3/5)
... = 1 : 3/5 : 2/3
Then the fraction the second towel is of the third towel is ...
... (3/5)/(2/3) = (3/5)·(3/2) = 9/10
To find the rule that represents the area of this triangle, you will need to know the rule for finding area of a triangle.
A = 1/2bh
The base of this triangle is the left vertical line, so to find the distance of this line you will subtract y2 and y1. The height of this triangle starts at (x3, y3), and moves directly to the left until it hits the base at a perpendicular intersection (90 degress).
This distance would be found by subtracting x3 and x1.
The correct answer is the 4th choice in the list.
Answer:
B. 2 + (3^2 * 5) - 3
Step-by-step explanation:
Hey! Sorry for the long wait, I'm still in school and can't really be here 24/7 but I'm proud to announce that I have your answer!
So we have 4 expressions and we need to get our answer to 44. This question already includes the notion that parenthesis placements make a huge difference, so let's review them.
<h2>A.</h2>
2 + 3^2 * (5 - 3)
Use PEMDAS
2 + 3^2 * 2
2 + 9 * 2
2 + 18
20
<h2>B.</h2>
2 + (3^2 * 5) - 3
2 + (9 * 5) - 3
2 + 45 - 3
47 - 3
44
<h2>C.</h2>
(2 + 3^2) * 5 - 3
(2 + 9) * 5 - 3
11 * 5 - 3
55 - 3
52
<h2>D.</h2>
(2 + 3)^2 * 5 - 3
(5)^2 * 5 - 3
25 * 5 - 3
125 - 3
122
As we can see, B. is our answer due to its equivlance to 44.
