Show how to write out 6/25- 4/5
not sure just what you're after, but
6/25 - 4/5 = 6/25 - 20/25 = -14/25
I need help for this question,
From the top of an 8m house, the angle of elevation to the top of the school’s flagpole across the street is 9 degrees. The angle of depression is 42 degrees to the bottom of the pole. How tall is the flagpole?
you should post your own question, not piggyback on someone else's where it might get lost.
Draw the diagram and review your basic trig functions. It should be clear that if the pole's height is h, then
8 cot42° = (h-8) cot9°
Now just solve for h
To write out the subtraction of fractions 6/25 - 4/5, follow these steps:
Step 1: Find a common denominator for the two fractions. The common denominator is the least common multiple (LCM) of the denominators, which is 25 and 5 in this case. The LCM of 25 and 5 is 25.
Step 2: Adjust the fractions to have the common denominator of 25.
To adjust the first fraction (6/25), we need to multiply both the numerator and denominator by the same number to get a denominator of 25. In this case, we don't need to do anything as the first fraction already has the desired denominator of 25.
To adjust the second fraction (4/5), we need to multiply both the numerator and denominator by the same number to get a denominator of 25. To do this, we multiply the numerator (4) by 5, which gives us 20. Therefore, the adjusted second fraction is 20/25.
Step 3: Subtract the two adjusted fractions.
Subtracting the adjusted fractions: 6/25 - 20/25 = (6 - 20)/25 = -14/25.
Therefore, 6/25 - 4/5 is equal to -14/25.
