Answer:

\sin \frac{11 \pi}{6} \text { is equivalent to } \sin \frac{7 \pi}{6}

Option: D

Step-by-step explanation:

\text { Given that, } \sin \frac{7 \pi}{6}

To find the equivalent option,

\text { We know that } \pi=180^{\circ}

\text { Take, sin } \frac{7 \pi}{6} \text { substitute the value of } \pi=180^{\circ} \text { then, }

\sin \frac{7 \times 180}{6}

=\sin \frac{1260}{6}

= sin 210

= -0.5

\sin \frac{7 \pi}{6}=-0.5

Now, check for all the options, select the option which is equal to -0.5.

Check for option: D  

\sin \frac{11 \pi}{6}\left(\pi=180^{\circ}\right)

=\sin \frac{11 \times 180}{6}

=\sin \frac{1980}{6}

= sin 330

= -0.5

\sin \frac{11 \pi}{6}=-0.5

\text { Therefore, } \sin \frac{11 \pi}{6}=\sin \frac{7 \pi}{6}

Two consecutive even whole numbers are selected. The difference between the reciprocals of the two numbers is 1/40. determine th
nevsk [136]

Answer:

2 numbers could be 10 and 12 

or - 12 and - 10 

Step-by-step explanation:

let the 2 numbers be x and x + 2

since they are 2 consecutive even numbers, the difference between them is 2

the difference between the reciprocals is 1/60 


we have to mulitply the 2 denominators x and (x+2) to get a common denominator for the 2 fractions 

= 

we can then remove the brackets from the numerator and denominator 


and then cross multiply

60 * 2 = x² + 2x

120 = x² + 2x

x² + 2x - 120 = 0

we have a quadratic equation which needs to be solved 

x² + 12x - 10x - 120 = 0

x (x + 12) - 10(x + 12) = 0

(x - 10) (x + 12) = 0

x - 10 = 0     or   x + 12 = 0

x = 10                x = -12

I Need The Answer Plz Geometry Is Hard!!
tensa zangetsu [6.8K]

Answer:

6.0.

Step-by-step explanation:

The line marked 20 is  2 times the line marked 3x - 8 (because the last line cuts the 2 sides of the large triangle in 2).

2(3x - 8) = 20

6x - 16 = 20

6x = 36

x = 6.0.

When converting from inches to feet, the measurement in inches, m, of an object varies directly with its measurement in feet, f,
djyliett [7]
12f=m
It can also be m/12=f, but since it is asking for inches to feet the first one is better
