Answer:

c = 30.56 to the nearest hundredth

Step-by-step explanation:

87 = 9/5 c + 32

87 - 32 = 9/5 c

9/5 c = 55

multiply both sides by 5/9:

c = 55*5 / 9

c = 30.56.

How to find the θ in this equation: tan(θ+16°)=1/tan(θ+60°) by using the trigonometric identities?thanks
DedPeter [7]

Answer:

\huge \theta  =7°

Step-by-step explanation:

tan( \theta + 16 \degree) =  \frac{1}{tan( \theta + 60 \degree) }  \\ tan( \theta + 16 \degree) =cot( \theta + 60 \degree) \\ tan( \theta + 16 \degree) = tan \{90 \degree - (\theta + 60\degree) \} \\ \theta + 16 \degree = 90 \degree - \theta  -  60\degree \\ \theta +\theta  = 30 \degree - 16\degree \\2 \theta  = 14 \degree  \\ \theta  =  \frac{14 \degree}{2}   \\   \huge \red{ \boxed{\theta  =7 \degree}}

Pls help me solve this thank u
zaharov [31]

Answer:

1. 12

2. 32

3. 8

4. 1

5. 14

Step-by-step explanation:

The above numbers represent the empty boxes from top to bottom.

1. (.4 +1.6) = 2 x 6 = 12

2. (24 ÷ 3 x 4) = 8 x 4 = 32

3. 8 ÷ (9-5) + 3 x 2. You have to remember Order of Operations on this one.

8 ÷ 4 + 3 x 2

2 + 6 = 8

4. 28 ÷ 7 x 1/4

4 x 1/4 = 1

5. (6 x 5) - (4 x 4)

30 - 16 = 14

hope this helps, brainliest is always appreciated.

tankabanditka [31]

Answer:

The inequality sign is not correct because the > symbol means greater than. However, up to and including $90 can be spent so the inequality sign should be ≥ (greater than or equal to).
