The additive inverse of something is whats added to the original to get 0
So in this case n - n = 0, which is B :)
Answer:
C) 18 cents
Step-by-step explanation:
Given,
This weeks deal -
Quantity of Flour Price ($) Price per pound ($)
3 pounds 5.25 (5.25/3) = 1.75
5 pounds 9.75 (9.75/3) = 1.95
7 pounds 12.60 (12.60/3) = 1.80
10 pounds 14.20 (14.20/3) = 1.42
12 pounds 18.24 (18.24/3) = 1.52
The lowest price per pound is $1.42. Therefore, this is the current week's best deal.
The last week's best deal was = $`1.60/pound
The difference between the unit price for previous week's best deal and this week's best deal = $1.60 - $1.42 = $0.18
Therefore, 18 cents.
1. The dimensions of the rectangle are 3 units by 4 units.
2. 0.3 x 0.4 = 0.12
They paid $218.75 every year as an interest rate.
This exercise is about creating two-dimensional shapes. The resulting shape is a quadrilateral - Square. See the attached for the lines drawn.
What was noticed about the two lines drawn?
- The two lines are drawn each had parallel pairs; and
- They were perpendicular to one another.
<h3>What is the meaning of perpendicularity?</h3>
When two lines intersect with one another such that they create a right angle, perpendicularity has occurred and both lines are said to be perpendicular to one another.
Hence:
- AB ⊥ BC
- BC ⊥ CD
- CD ⊥ DA; and
- DA ⊥ AB.
