Find the value of tan(210°).
\(\frac{1}{\sqrt{3}}\)
\(-\frac{1}{\sqrt{3}}\)
-1
1
To find the value of \(\tan(210^\circ)\), we can use the concept of reference angles and the periodicity of trigonometric functions. We will determine the quadrant in which \(210^\circ\) lies and then relate it to an angle in the first quadrant.
A) \(\frac{1}{\sqrt{3}}\) is the correct value for \(\tan(210^\circ)\).
This problem can be solved using the concept of work and time, specifically by calculating the total work units and then determining the remaining work and the time taken by the increased number of workers.
Calculate the total work: If 15 men can do a work in 330 days, the total work can be expressed in "man-days".
\[ \text{Total Work} = \text{Number of Men} \times \text{Number of Days} \] \[ \text{Total Work} = 15 \text{ men} \times 330 \text{ days} = 4950 \text{ man-days} \]Calculate work done in the first 220 days: For the first 220 days, 15 men worked.
\[ \text{Work Done} = 15 \text{ men} \times 220 \text{ days} = 3300 \text{ man-days} \]Calculate the remaining work: Subtract the work done from the total work.
\[ \text{Remaining Work} = \text{Total Work} - \text{Work Done} \] \[ \text{Remaining Work} = 4950 \text{ man-days} - 3300 \text{ man-days} = 1650 \text{ man-days} \]Calculate the new number of men: After 220 days, 15 more people are recruited.
\[ \text{New Number of Men} = 15 + 15 = 30 \text{ men} \]Calculate the number of additional days to complete the remaining work: Divide the remaining work by the new number of men.
\[ \text{Additional Days} = \frac{\text{Remaining Work}}{\text{New Number of Men}} \] \[ \text{Additional Days} = \frac{1650 \text{ man-days}}{30 \text{ men}} = 55 \text{ days} \]Correct Option: C) 55 days

Arrange the following fractions in ascending order:-
\( \frac{11}{17} \) < \( \frac{41}{63} \) < \( \frac{3}{7} \) < \( \frac{21}{29} \)
\( \frac{41}{63} \) < \( \frac{3}{7} \)< \( \frac{21}{29} \) < \( \frac{11}{17} \)
\( \frac{3}{7} \) < \( \frac{11}{17} \) < \( \frac{41}{63} \) < \( \frac{21}{29} \)
\( \frac{3}{7} \) < \( \frac{11}{17} \) < \( \frac{21}{29} \) < \( \frac{41}{63} \)
To arrange fractions in ascending order, we need to compare their values. One effective method is to convert each fraction into its decimal equivalent. This allows for straightforward comparison.
Convert each fraction to a decimal:
List the decimal values:
Arrange the decimal values in ascending order:
\[ 0.428 < 0.647 < 0.650 < 0.724 \]Replace the decimal values with their original fractions:
\[ \frac{3}{7} < \frac{11}{17} < \frac{41}{63} < \frac{21}{29} \]C) \( \frac{3}{7} \) < \( \frac{11}{17} \) < \( \frac{41}{63} \) < \( \frac{21}{29} \)
This order matches the ascending order derived from the decimal conversions.
