Answer: 998400 square inches or 6933 1/3 square feet or
770.37 square yards.
Step-by-step explanation:
Multiply 1280×780 for square inches. Divide that amount by 144 to get square feet. Then divide that by 9 to get square yards.
You can solve <span>9/x-4/y=8 for x or for y but NOT at the same time.
Solving for x: </span><span>9/x-4/y=8 Mult all 3 terms by xy to eliminate the fractions.
9(xy)/x - 4xy/y = 8xy => 9y - 4x = 8xy, or 9y = 4x + 8xy = 4x(1+2y)
then 9y = x [ 4(1+2y) ]
9y
therefore x = ------------
4(1+2y)
Solve for y using a similar approach.

It depends on the precision you want.
Considering the data you've given, if you want the result in cm, the numbers should be rounded to 9 and 3, thus giving a total of 12, with two significant numbers.
But taking into account the precision you've reported, looks like the decimals do matter, and in that case, the numbers should be rounded to 9.0 and 2.8, giving a total of 11.8, thus, three significative figures.
Answer:Height to width is 3:4
Width to height is 4:3
Step-by-step explanation:
A TV screen is 15 inches high and 20 inches wide.
Height of TV screen is 15 inches
Width of TV screen is 20 inches
To find ratio of Height to width
we replace the numbers in the ratio Height : width
15: 20
Divide both numbers by 5, so ratio becomes
3: 4
Height to width is 3:4
To find ratio of Width to height
we replace the numbers in the ratio Width : height
20:15
Divide both numbers by 5, so ratio becomes
4:3
Width to height is 4:3
