the length of the line is 2 1/16
Answer:
We can set up a system of equations.
x + y = 111
0.25x + 0.10y = 18.30
x + y = 111
Subtract 'y' to both sides:
x = -y + 111
Plug in '-y + 111' for 'x' in the 2nd equation:
0.25(-y + 111) + 0.10y = 18.30
Distribute 0.25 into the parenthesis:
-0.25y + 27.75 + 0.10y = 18.30
Combine like terms:
-0.15y + 27.75 = 18.30
Subtract 27.75 to both sides:
-0.15y = -9.45
Divide -0.15 to both sides:
y = 63
Plug this back into any of the two equations to find the 'x' value.
x + y = 111
x + 63 = 111
Subtract 63 to both sides:
x = 48
So there are 48 quarters and 63 dimes.

Using distributive property,
f * n = fn
f * 5 = 5f
= fn + 5f
Given:
The ratio of the area between a small square of land and a large square
of land is 3: 7.
Total area of the two squares of land (in sq. meter) is 4000.
Required:
The area of each square of land.
Answer:
We have the ratio of the area between a small square of land and a large square of land is 3: 7.
Let

be the area of the square of land.
Then their ratio is given by,

Also given that the total area of the two squares of land (in sq.meter) is
4,000.
The area of
Therefore,

Therefore,the area of small square (in sq. meter) is,

and the area of large square (in sq. meter) is,

Final Answer:
The area of small and large square respectively (in sq. meter) is,1200 and 2800.
