Given: 2/3 every 30 seconds
If we cut 2/3 in half, we get 1/3. This would also mean we cut the time in half 30 / 2 = 15 seconds
Therefore, 1/3 of the length every 15 seconds.
15 + 15 + 15 = 45 seconds to go the full length of the path
The statement, "the lateral surface area of cone A is exactly half of that of cylinder B" is: A. True.
<h3>What is the Lateral Surface Area of a Cone and a Cylinder?</h3>
Lateral surface area of cone = πrl
Lateral surface area of cylinder = 2πrh
Lateral surface area of cone A = πrl = πrh
Lateral surface area of cylinder B = 2πrh
This means the lateral surface area of cylinder B is twice that of cone A. Thus, lateral surface area of cone A is exactly half of that of cylinder B.
The answer is: A. True.

Given the previous length of the bedroom and the current scale factor, the length of the bedroom in the current scale drawing is 1008ft.
<h3>What is the length of the bedroom in the scale drawing?</h3>
Scale factor is simply a measure for similar figures, who look the same but have different scales or measures.
To get new dimension;
New dimension = scale factor × current dimension
Given that;
- Current length of the bedroom = 9ft
- Current width of the bedroom = 11ft
- Scale factor = 112
- New length of the bedroom = ?
New dimension = scale factor × current dimension
New length of the bedroom = 112 × 9ft
New length of the bedroom = 1008ft
Therefore, given the previous length of the bedroom and the current scale factor, the length of the bedroom in the current scale drawing is 1008ft.

The three inside angles of a triangle need to equal 180 degrees.
Add the 3 equations together and set to equal 180:
7x+4 + 5x+3 + 2x+5 = 180
Simplify by combining the like terms:
14x + 12 = 180
Subtract 12 from each side:
14x = 168
Divide both sides by 14:
x = 168/14
x = 12
