A tree cast a 32.5-foot-long shadow at the same time a 24 foot flagpole cast a 15 foot-long shadow. Find the height of the tree

Solution:

Given that,

Let, Height of tree = x

shadow of tree = 32.5 feet

height of flagpole = 24 foot

shadow of flagpole = 15 foot

Set up a proportion comparing the height of each object to the length of the shadow

Therefore,

Substituting the values we get,

Thus height of tree is 52 feet

i just took the test, the correct answer is .. 31.5 in.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
