Answers
1) 3
2)9
3) 27
4) 81
So writing his score after four turns is simple. 3 tripled four times is 3 to the fourth power, wich as you can see from above is 81.

Step-by-step explanation: The sum of the interior angles of a regular polygon is calculated as follows;
(n-2) × 180° {where n represents the number of sides of the polygon}
A pentagon is a polygon with five equal sides. Therefore the sum of it's interior angles is calculated as;
(5-2) × 180°
=3×180°
=540°
A hexagon is a polygon with six equal sides. Therefore the sum of it's interior angles is calculated as;
(6-2) × 180°
=4×180°
=720°
Therefore, the ratio of the number of degrees in the interior angles of a regular pentagon, to the number of degrees in the interior angles of a regular hexagon is given as
540:720
If you divide both sides by their prime factors (2×2×3×3×5) the ratio becomes
3:4 in it's simplest form.
As a common fraction, it can be expressed as
3/4.

If cold water pipe is turned on and hot water pipe is turned on 3 hours later then it will take 36 minutes (or 0.6 hr) to them to fill the pool together.
Step-by-step explanation:
Given :
Cold water pipe can fill a swimming pool in 4 hours, and a hot water pipe in 6 hours.
Solution :
Let's say the swimming pool is x gallons.
The flow rate of the cold water pipe is,
The flow rate of the hot water pipe is,
If the cold water pipe is turned on for three hours, the volume of water is:
The time to fill the rest of the pool with both the cold and hot water pipes is,
= 0.6 hr
If cold water pipe is turned on and hot water pipe is turned on 3 hours later then it will take 36 minutes (or 0.6 hr) to them to fill the pool together.

Answer:
0.6 hours
Step-by-step explanation:
Let's say the swimming pool is 12,000 gallons.
The flow rate of the cold water pipe is:
12000 gal / 4 hr = 3000 gal/hr
The flow rate of the hot water pipe is:
12000 gal / 6 hr = 2000 gal/hr
If the cold water pipe is turned on for three hours, the volume of water is:
3000 gal/hr × 3 hr = 9000 gal
That leaves 3000 gallons. The time to fill the rest of the pool with both the cold and hot water pipes is:
3000 gal / (3000 gal/hr + 2000 gal/hr) = 0.6 hr
It takes 0.6 hours (36 minutes).

x=5
Answer:
x = 5.
Step-by-step explanation:
2x + 1 = 11
Subtract 1 from both sides:
2x = 11 - 1 =10
Divide both sides by 2:-
x = 10/2
x = 5.

6 km = 6 * 1,000,000 millimeters = 6,000,000 mm
6,000,000 mm is greater than 54.000 mm
Therefore, 6 km is greater than 54,000 mm,
6km= 6000000mm
6000000mm > 54000mm
so 6km is greater than 54000mm
