What angle is angle b

vodka [1.7K]3 years ago

4 0

Answer:

angle v = 46 degrees

Step-by-step explanation:

tan-1 = $\frac{opposite}{adjacent}$

tan-1 V = $\frac{21}{20}$

$\frac{21}{20}$ = 1.05

tan-1 V = 1.05

V = 46.397

round to the nearest whole number:

46.397 = 46

9+3.5g=11-0.5g brainliest to whoever gives steps

kow [346]

Answer:

The answer is g = 0.5

Step-by-step explanation:

1. Your equation is :

9+3.5g=11-0.5g

2. First, multiply both sides by ten

9 * 10 + 3.5 * 10 = 11 * 10 - 0.5 * 10

3. Next we refine the equation

90 + 35g = 110 - 5g

4. Now, lets subtract 90 from both sides

90 + 35g - 90 = 110 - 5g - 90

5. Simplify

35g + 5g = -5g + 20 + 5g

6. We then add 5g to both sides

35g + 5g = -5g + 20 + 5g

7. Simplify again

40g = 20

8. Now, divide both sides by 40

40g/40 = 20/40

9. And finally, simplify once again to get your final answer.

g = 1/2 or 0.5

I hope this helped :)

Mr Patel is planning to drive 325 miles. He will stop one hour for lunch and take a 15 min rest break.

mr_godi [17]

Option D

The trip lasts for $6\frac{1}{4}\ hours$

Solution:

Mr Patel is planning to drive 325 miles

Average speed is 65 mph

He will stop one hour for lunch and take a 15 min rest break

Let us first find the time taken

$Time = \frac{distance}{speed}$

$Time = \frac{325}{65}\\\\Time = 5$

Thus he covers 325 miles in 5 hours

Also, given that, he will stop one hour for lunch and take a 15 min rest break

Therefore, total time taken for trip is:

Total time = 5 hours + 1 hour + 15 minutes

Total time = 6 hours 15 minutes

We know that,

1 hour = 60 minutes

Therefore,

$6\ hours\ 15\ minutes\ = 6 + \frac{15}{60}\ hours = 6 + \frac{1}{4} = 6\frac{1}{4}\ hours$

Thus the trip lasts for $6\frac{1}{4}\ hours$
