Answer:
20/155
Step-by-step explanation:
If the original angle is x degrees then its supplement is 180 - x degrees.
we have the equation:-
180 - x = 3x + 20
160 = 4x
x = 40
The original angle is 40 degrees and its supplement is 140 degrees

Answer:
31.5%
Step-by-step explanation:
If 70% of customers get an oil change, and 45% of those get their tires rotated, then this is a method I use to find the answers to these types of problems.
70% of customers, 45% of 70
One method that will help you so much is this simple equation: x% of y= y% of x. For example, if you need to find 3% of 50, the same value is given for 50% of 3, which would be 1.5. Using our given digits,45% of 70 is the same as 70% of 45.
A method that can add on to this is one I've come up with myself. If you divide your original number by 100, then multiply it by your given percentage, it will give you your wanted value, so if you plug in your values, 70/100, multiplied by 45, will equal 31.5%.
Answer:
5 times
Step-by-step explanation:
Assume the height of the streetlamp to be x
If you make a diagram from the details given by the question you should find two pairs of similar sides, from which you can form the equation
Solving this gives the height of the streetlamp as 30 feet. Divide this length by the height of the man to get the number of times the streetlamp is taller.
