Answer:
The inequality that models the situation is 
Step-by-step explanation:
Let
x ----> represent the number of small candles
y ----> represent the number of large candles
we know that
The inequality that represent this situation is equal to
using a graphing tool
The solution is the shaded triangular area, because the number of candles cannot be a negative number
see the attached figure
Notice that the 2 graphs intersect when x = 12 minutes. That's your answer.
The unit cost decreases the more you buy at once. 1.10/1 = $1.10 you're paying $1.10 per 1. 1.98/2 = $ .99 you're paying $.99 per 1 2.89/3 = $.96 you're paying $.96 per 1. When you buy 9 you're paying less per 1 than you are when you buy 1
Answer:
Step-by-step explanation:
a) area of the rectangle = length × breadth
Therefore area should be = 12cm × 6cm
Which should give you the answer 72centimetre squared.
b) area of triangle A = 1/2 × b × h
So that is 1/2 × 3 × 6
Which is 18 centimetres × 1/2
Which is 9 centimetres squared
c) area of triangle B = 1/2 × b × h
So 1/2×3×6=18
Now 1/2×18 should give you 9 centimetres squared
d) therefore the area of the parallelogram = 72+9+9=90 centimetres squared
Therefore the area of the parallelogram is 90 centimetres squared
Answer:
I think the way they are telling is that the triangle will move to the third quadrant,
If so, then the coordinates of P'Q'R' will just be the negative of PQR.
