Final price of the Shoes
= sticker price - 30%(sticker price) - 10 - 4
= 60 - 30%(60) - 10 - 4
= 60 - 30/100(60) - 10 - 4
= 60 - 18 - 10 - 4
= (60) + (-18 -10 -4)
= 60 - 32
= 28
Therefore the pair of shoes costs $28.00.
9x10^7
10x10=100x10=1,000
1,000x10=10,000
10,000x10=100,000
100,000x10=1,000,000
1,000,000x10=10,000,000
10,000,000x9=90,000,000
3x10^3
10x10=100x10=1,000
1,000x3=3,000
90,000,000/3,000=30,000
So 9x10^7 is 30,000x larger than 3x10^3
hope it helps!
Answer:
length = 8m
width = 4m
Step-by-step explanation:
The perimeter of a rectangle is the formula: P = 2w + 2l, where 'w' is equal to the width and 'l' is equal to the length. In this case, the width can be expressed as 'w' and the length, which is '4 meters longer than its width' would be 'w +4'. So, when you put these expressions into the equation:
P = 2w + 2(w +4)
P = 2w + 2w + 8 or 4w + 8
Since perimeter = 24m, plug it in and solve for 'w':
24 = 4w + 8
Subtract 8 from both sides: 24 - 8 = 4w + 8 - 8 or 16 = 4w
Solve for w: w = 4m
Solve for l: l = w + 4 or 4+4, so l = 8m
