Answer:

x > 3

Step-by-step explanation:

Step 1: Write inequality

3x + 6 > 30

Step 2: Solve for <em>x</em>

  1. Subtract 6 on both sides: 3x > 24
  2. Divide both sides by 3: x > 3

A plane flew for 2 hours at 467 mph (miles per hour) and 5 hours at 536. How far did the plane fly in miles
Archy [21]

Answer:

3614 miles

Step-by-step explanation:

Given data

A plane flew for 2 hours at 467 mph

Let us find the distance covered

Speed= distance/time

Distance= speed*time

Distance= 467*2

Distance=934 miles

5 hours at 536

Let us find the distance covered

Speed= distance/time

Distance= speed*time

Distance= 536*5

Distance=2680 miles

Total distance

=2680+934

=3614 miles

Solve the equation sin2∅=2sin∅, domain 0°≤B≤360°
Ann [662]

Answer:

∅ = 90°

Step-by-step explanation:

Given;

sin2∅=2sin∅

sin2∅ = 2sin∅Cos∅

but, Sin²∅ + Cos²∅ = 1

       Cos²∅ = 1 - Sin²∅

       Cos ∅ = √(1 - Sin²∅)

sin2∅=2sin∅ ↓

2sin∅Cos∅ = 2sin∅

2sin∅(√(1 - Sin²∅)) = 2sin∅

Let Sin∅ = P

2P( √(1 - P²)) = 2P

Divide both sides by 2P

√(1 - P²) = 1

Square both sides

1 - P² = 1

P² = 1 - 1

P² = 0

P = 0

Recall, Sin∅ = P

Sin∅ = 0

∅ = Sin ⁻¹(0)

∅ = 90°

The time in new York is 16.45 (EDT).what is the time in brisbane(AEST)which is 14 hours ahead?
elena-s [515]
Answer: 06.45

Explanation: For this problem, it is essential to know that there are 24 hours in a day. With that said, we take our starting time of 16.45 and since we want to know what time it is 14 ahead (addition), we add the two numbers together.

16.45 + 14 = 30.45

Since there are only 24 hours in a day, and we have exceeded that value, we subtract 24.

30.45 - 24 = 06.45

And that is the time in Brisbane.

Alternatively, you can count time in 12-hour format and convert 16.45 to 4.45 pm by subtracting 12.

Knowing your start time is 4.45pm simply add 14 to that (or change the pm to an and add 2 since 14-12=2).

You will again get 6.45am.

Cheers.
