Answer:

Helium is basically a chemical element in the noble gas group found especially in natural gases and used chiefly for inflating airships and balloons, as a coolant for superconductors, and as a component of inert atmospheres (as in welding). It's colorless, odorless inert gaseous element It is used as a component of artificial atmospheres and laser media, as a refrigerant, as a lifting gas for balloons, and as a superfluid in cryogenic research. On the  periodic table It is on the Atomic number 2

Answer: Helium is a chemical element in the group known as noble gases. It is used to inflate things like balloons, balls, and air balloons. These are some uses of the element. Helium is a very known element. Hope this helps you!

The boiling point of water is lower on the mountaintop because the air pressure is lower.

Boiling point is defined as the temperature at which the pressure that a liquid is subjected to from its environment equals the pressure that the liquid's vapor is subjected to: In this case, adding heat causes the liquid to evaporate without raising the surrounding air's temperature. The effects of temperature, pressure in the atmosphere, and vapor pressure on a liquid's boiling point are discussed.

On a mountaintop, there is less air pressure pressing down on the molecules, causing the water to boil at a lower temperature. Pressure causes a rise in the boiling point of water. At low pressure, water's boiling point drops.

Thus, the boiling point of water is lower on the mountaintop because the air pressure is lower.

Answer:

i think B

Explanation:

Answer: D

Explanation:

The expression for the statement that is given is (m² + n²) - 2mn

The expression given is that twice the product of m and n is decreased by the square of the sum of m and n. This will be written as:

= [2 × (m × n)] - (m + n)²

= 2mn - (m² + n²)

= (m² + n²) - 2mn

In conclusion, the correct option is D.

To write an inequality that illustrates the weight limit for a group of adults and children on the fishing boat, let's assume that the letter a corresponds to the number of adults and the letter c corresponds to the number of children.

So, let's calculate:

[tex]150a + 10a = 160a\\ 75c + 10c = 85c[/tex]

The total weight on the boat by people corresponds to:

[tex]160a + 85c [/tex]

Now, let's add 200 pounds of equipment to this amount, and remembering that the total weight cannot exceed 1200 pounds, so we will find the following inequality:

[tex]160a + 85c + 200 \leq 1200[/tex]

Or else:

[tex]160a + 85c\leq 1000[/tex]

The next step is to calculate the inequality for the passenger limit, remembering that this number cannot exceed 8:

[tex]a + c \leq 8[/tex]

Thus, we find a system of linear inequalities:

[tex]160a + 85c\leq 1000[/tex]

[tex]a + c \leq 8[/tex]

In order to be able to answer which of the groups can safely rent a boat, we will make the following calculations substituting the values in the inequalities found.

[tex]160(4) + 85 (2) + 200 = 1010\leq 1200[/tex]

[tex]160(3) + 85 (5) + 200 = 1105\leq 1200[/tex]

[tex]160(8) + 200 = 1480\leq 1200[/tex]

Therefore, through the calculations it can be stated that group 1 and group 2 can safely rent a boat, but group 3 exceeds the weight limit.

There are other possible combinations that can be found graphically.

Explanation:

Since 1 inches per 5 miles.

therefore for 60miles it would be 60/5=12

12 inches added to the value of 3inches starting form the start

the answer would then be 12+3= 15 minutes

Hope it helps

If the distance from the start to the destination is 3 inches on the map, it will take 15 minutes take the car to make the trip. The correct option is B.

Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.

In navigation, it is utilized. The distance formula is used by a pilot to determine how far apart their plane is from the other plane. They locate the plane's coordinates before using the distance formula to calculate the distance.

Since 1 inch per 5 miles.

Therefore, for 60 miles it would be 60 / 5 = 12

12 inches added to the value of 3 inches starting from the start

Therefore, the correct option is B: 15 minutes.
