Answer:
$24
Step-by-step explanation:
First, find the cost to cover one pair of shoes.
Cost to cover one pair of shoes = surface area of the shoe box × cost per square inch
= 2(LW + LH + HW) × 0.02
L = 14 in.
W = 8 in.
H = 4 in.
Plug in the values
Cost to cover one pair of shoes = 2(14*8 + 14*4 + 4*8) × 0.02
= 2(112 + 56 + 32) × 0.02
= 2(200) × 0.02
= 400 × 0.02 = 8
Cost to cover one pair of shoes = $8
Cost to cover 3 pairs of shoes = 3*8 = $24
Answer:
41.472 m²
8.449m²
Step-by-step explanation:
c) scale facot is 7.2/5 = 1.44
the square scale factor is 1.44^2 = 2.0736
times 20 by this to get the area
2.0737x 20 = 41.472 m²
d) 2.8/6 = SF = 0.467
0.2178 x 38.8 = 8.449m²
Answer:
x = 0
Step-by-step explanation:
Expanding the left hand side we get
Taking 6 from left hand side to right hand side
Dividing both sides by 2
So, x = 0
First you should find the discount so you can say:
10/100 = ?/82
so ? is your discount and ? is equal to:
? = 82*10/100 = 8.2
so your discount is $8.2 and your sale price will be:
$82 - $8.2 = $73.8 :)))
I hope this is helpful
have a nice day

Step-by-step explanation:
7*3x= 7- 3x - 9
21x = -2-3x
24x =-2
x=-1/12
