Answer:

-(√105)/11

Step-by-step explanation:

Tangent is the ratio of sine to cosine. When tangent is positive, sine and cosine have the same sign. This means the appropriate choice will be either the first one or the last one.

cos(θ) = -√(1 - sin(θ)²) . . . . in the 3rd quadrant

... = -√(1 - (-4/11)²)

... = -(1/11)√(121 -16)

... = -(√105)/11 . . . . . . matches the first selection

Ronch [10]

<h2>Complete Question: </h2>

Learning Task 1: Identify similar and dissimilar fractions. On your note- book write S if the fractions are similar and D if dissimilar.

1. $\frac{2}{3} $ and $ \frac{1}{3}$

2. $\frac{3}{4} $ and $ \frac{1}4}$

3. $\frac{4}{7} $ and $ \frac{7}{8}$

4. $\frac{2}{5} $ and $ \frac{5}{11}$

5. $\frac{7}{13} $ and $ \frac{7}{9}$

<h2>The answers:</h2>

1. $\frac{2}{3} $ and $ \frac{1}{3}$ - Similar (S)

2. $\frac{3}{4} $ and $ \frac{1}4}$ - Similar (S)

3. $\frac{4}{7} $ and $ \frac{7}{8}$ - Dissimilar (D)

4. $\frac{2}{5} $ and $ \frac{5}{11}$ - Dissimilar (D)

5. $\frac{7}{13} $ and $ \frac{7}{9}$ - Dissimilar (D)

Note:

Similar fractions have the same denominator. i.e. the bottom value of both fractions are the same.
Dissimilar fractions have different value as denominator, i.e. the bottom value of both fractions are not the same.

Thus:

1. $\frac{2}{3} $ and $ \frac{1}{3}$ - They have equal denominator. Both fractions are similar (S).

2. $\frac{3}{4} $ and $ \frac{1}4}$ - They have equal denominator. Both fractions are similar (S).

3. $\frac{4}{7} $ and $ \frac{7}{8}$ - They have equal denominator. Both fractions are dissimilar (D).

4. $\frac{2}{5} $ and $ \frac{5}{11}$ - They have equal denominator. Both fractions are dissimilar (D).

5. $\frac{7}{13} $ and $ \frac{7}{9}$ - They have equal denominator. Both fractions are dissimilar (D).

Therefore, the fractions in 1 and 2 are similar (S) while those in 3, 4, and 5 are dissimilar (D).

coldgirl [10]

Answer: $186^{\circ}F$

Step-by-step explanation:

Given : In the Sahara Desert one day it was 136°F.

In the Gobi Desert a temperature of -50°F was recorded.

Clearly , 136°F> -50°F

Then, the difference between these two temperatures will be :-

$136^{\circ}F-(-50)^{\circ}F\\\\=(136+50)^{\circ}F\ \ [\because \text{Product two neagtive sign is positive]}\\\\=186^{\circ}F$

Hence, the difference between these two temperatures = $186^{\circ}F$
