Answer:
Height of the tree is 50 ft.
Step-by-step explanation:
AB/DE =BC/EC
ratio is x/5 = 120/12
x/5 = 10
x=50
25=.75x or 25 divided by .75= x
7 + 4= x so 7+4 = 11
Best way to tell is to convert them all to either decimals, fractions, or percentages. I usually convert to decimals. So, 75% is 0.75. 0.9 is already a decimal. And 4/5 is 0.8.
So 0.75, or 75%, is now clearly the smallest. In order from least to greatest, they go 75%, 4/5, and 0.9.
Answer:
(First step for obtaining a common denominator for the two fraction)

Step-by-step explanation:

where,
a is acceleration of an object.(Need to calculate)





Now we will simplify above expression for a
First we make common denominator.
Common denominator is 7. So, we make both denominator 7. We multiply by 7 at top and bottom with 3. We get
(First step for obtaining a common denominator for the two fraction)
Now we combine the numerator
