Y is inversely proportional to x^2. Given that y = 2.5 when x = 24,

1) find an expression for y in terms of x

2) find the value of y when x = 20

3) Find a value of x when y = 1.6​

step-by-step explanation:

9 x 8 divided by (5-3)=36

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
