Answer 1

Plots of land between two roads are laid out according to the boundaries shown. The boundaries between the two roads are parallel. What is the length of Plot 3 along Cheshire Road?
a.46 2/3
b.67 1/5
c.66
d.37 1/3

Answer 2

fan + medal

Answer 3

To find the length of Chesire Road you would do a porportion....

\(\LARGE{\frac{ 40 }{ 48 }=\frac{ x }{ 56 }}\) You would cross multiply....

\(\LARGE\color{green}{2,240 = 48x}\) in which we divide 48 from both sides....what would be the answer?

Answer 4

thanks can you help wit more i kinda suck at this math thing

Answer 5

sure ^^

Answer 6

thanks

Answer 7

and i need to calculate the geometric mean of 275 and 11 can you explain how to do it

Answer 8

im good at math its just this geometry thing is kinda confusing

Answer 9

This one is easy ^^ you would set this up as a porportion....

\(\LARGE{\frac{275}{x}=\frac{x}{11}}\) next you cross multiply in which it would equal...

\(\LARGE\color{purple}{3,025=x^2}\) Now we need to find the square root of 3,025....

\(\LARGE\color{red}{x=\sqrt{3025}}\)....when you get your answer the geometric mean would be the positive and the negative of the number....

Answer 10

ok so it would be 55 right

Answer 11

Correct ^^ sorry my internet is bad right now....so i might get on and off

Answer 12

So the geometric mean is 55 and -55

Answer 13

do you understand?
