3 3/4 inches = (3 3/4 / 12) feet = 0.3125 feet
120 feet requires ------- x number of board.
120 feet/0.3125 feet / board = 384 boards.
1 board costs 1.40
384 boards cost x
1.4 * 384.00= x*1 = x
537.60 dollars.
Note if you need to do this by dimensional analysis, it will look like this.
120 feet/fence [ 1 board / 3.75 inches] [ 12 inches/foot] [1.40 dollars / board]
All units that can be cancelled should be.
The result is 537.6 dollars / fence which is the answer you got.

Laptop's sale tax
=6/100 x 650
=39
Power adapter's sale tax
=6/100 x 59
=3.54
Total Sales tax=
39+3.54
=42.54
Answer:
3 5/7
subtract the 3/7
4 3/7 - 3/7 = 4
4 = 28/7
28/7 - 2/7 = 26/7
26 /7 = 3 remainder 5 so 3 5/7
the whole number is the answer and the remainder is the numerator
3 5/7 is the answer
Hope this helps
Step-by-step explanation:
Answer: We have c = 3 and d = -2
Step-by-step explanation:
We want to solve the equation:
6200.07 = 6.2x10^c + 7x10^d
First, we can separate the left number into two pieces:
6200.07 = 6200 + 0.07 = 6.2x10^c + 7x10^d
Now we can solve it as:
6200 = 6.2x10^c
6200/6.2 = 10^c
1000 = 10^c
now we can use that if y = a^x, then ln(y)/ln(a) = x
here we have:
c = ln(1000)/ln(10) = 3
and
0.07 = 7x10^d
0.07/7 = 10^d
0.01 = 10^d
d = ln(0.01)/ln(10) = -2
