Answer:
1/2 inch
Step-by-step explanation:
The area of a rectangle is the product of its length and width. So, the length and width of the photo will give a product of 24 when they are multiplied together.
One set of factors of 24 is 4 and 6, each of which is 1 unit less than the 5 and 7 dimensions of the paper on which the photo is printed. Hence a 1/2-inch border all around will result in a printed photo that is 4x6 on a 5x7 piece of paper.
___
If you want to write and solve equations, you can let b represent the border width. Then the photo area is ...
(5 -2b)(7 -2b) = 24
35 -24b +4b^2 = 24
4b^2 -24b +11 = 0
(2b -1)(2b -11) = 0
Solutions to this quadratic are b = 1/2, b = 11/2. The only viable solution is b = 1/2.
The border is 1/2 inch wide.
There are 60 ( ' ) minutes in 1 degree, and 60 ( " ) seconds in 1 minute.
now, on a Latitude of 42.54°, there are 42° clearly, how much is the 0.54 anyway?
well, we know there are 60 minutes in 1 degree, therefore 0.54 * 60 is how many minutes in 0.54, or 32.4'. So a whole 32' and 0.4 of a minute.
how many seconds in 0.4 minutes? well, there are 60 seconds in 1 minute, thus 0.4* 60, or 24.
L42.54 is then 42° 32' 24".
Convert 10% into a decimal
(0.1)^{2} - (5%)^{2}
Remove parentheses around 0.1
0.1^{2}-(5%)^{2}
Raise 0.1 to the power 2 to get 0.1
0.01-(5%)^{2}
Convert 5% to a decimal
0.01-(0.05)^{2}
Remove parentheses around 0.05
0.01-0.05^{2}
Raise 0.05 to the power of 2 to get 0.0025
0.01-1*0.0025
Multiply -1 by 0.0025 to get -0.0025
0.01-0.0025
Subtract 0.0025 from 0.01 to get 0.0075
You Answer is: 0.0075
Y=kx+b
(0,2),(5,8)
2=0k+b
8=5k+b
y=1.2x+2
