Answer:
172.5
Step-by-step explanation:
Use similar triangles and a proportion.
(tree height)/(tree shadow length) = (your height)/(your shadow length)
x/(270 ft)= (5 ft 9 in.)/(9 ft)
x/(270 ft)= (5 ft + 9/12 ft)/(9 ft)
x/(270 ft)= (5.75 ft)/(9 ft)
9x = 270 * 5.75 ft
x = 30 * 5.75 ft
x = 172.5 ft

Make d the subject
The first one 5 lb is the answer
Sin60=DF/FE
Root 3/2= DF/ 18 Root 3
DF= 18*3/2
DF= 27 units
cos60=DE/FE
1/2=DE/18 Root 3
DE= 18 Root 3/2
DE= 9 Root 3 units
So what we gotta do is isolate the variable by
writing it out like this
4 1/4 25 those are the numbers where those go are like this
4x - 1/4 < 25 then move on to the next line on here we write out
4x + 1/4 - 1/4 < 25 + 1/4 (The reason why i put + 1/4 is because you have to isolate the variable by doing addition as well And i always find it easier to convert the fractions to decimals then after you make that line you make the next one like this you have to add 1/4 to 4x then take it away (which is 4x) then put that to the side like this 4x ? ? then we need to find those two ?s by adding 25 and 1/4 (or o.25) which is 25.25 then we need to add that to the second answer 4x ? 25.25 when you have this you need to find out which one is bigger so it is 4x<25.25 (or 25 1/4) then we need to divide 4 and 25.25 to get 6.25 so
the answer is x < 6.25 so c is your awnser
