Step-by-step explanation:
One pound = $0.65
Total cost = c
Number of pounds to ship = p
Part a:
c = 0.65p
When p = 2
c= 0.65(2)
c = $1.30
Part b:
One pound = $0.65 - $0.05 = $0.60
c= 0.6p
Answer: (a) $1.30 (b) c= 0.6p
Answer:
219.1
Step-by-step explanation:
Mean: Add all numbers together and divide by the amount of numbers
Numbers added together = 2,191
2,191/10 = 219.1
Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
Here b = 13 and h = 4 , thus
A =
× 13 × 4 =
× 52 = 26 units² → A
SA= bh+2ls+lw
SA= 26*10 +40*26(2)+40*10
SA=260+1040(2)+400
SA=260+2080+400
SA=2740
