The number of hydrogen atoms is not a function of the number of oxygen atoms. This is because the number of hydrogen atoms in a molecule of water is always twice the number of oxygen atoms. This relationship is defined by the chemical formula of water, which is H2O. Therefore, the number of hydrogen atoms is a fixed value and it doesn't change based on the number of oxygen atoms.

Beth's class took a field trip to the art museum. It took them 55 minutes to drive to the museum. They stayed at the museum for 1 hour and 33 minutes. When the class left the museum, it was 9:41 A.M. What time did Beth's class leave for the field trip?
PLS HELPPPP I give 50.
Answers
Answer:
Beth's class left for the field trip at 7:13 A.M..
Step-by-step explanation:
To find out what time Beth's class left for the field trip, we need to subtract the time elapsed at the museum and the time it took them to drive there from 9:41 A.M.
The time elapsed at the museum was 1 hour and 33 minutes which is equivalent to 93 minutes.
To find out what time they left for the field trip, we need to subtract 55 minutes (the time it took them to drive there) and 93 minutes (the time they spent at the museum) from 9:41 A.M.
9:41 A.M. minus 55 minutes is 8:46 A.M..
8:46 A.M. minus 93 minutes is 7:13 A.M..
Therefore, Beth's class left for the field trip at 7:13 A.M..
I hope that helps!
Answer:
6:59am
Step-by-step explanation:
1 hour and 33 minutes = 93 minutes
55 minute ride to museum
93+55=148
60 minutes in 1 hour
148 divided by 60 = 2 hours 46 minutes
Time Left: 9:41
9.41-2.46
6.59
They left at 6:59am
There are 5 kids who want to start a game of Red Rover. Then 12 more kids come to play. If there are 2 teams in Red Rover, which of the following best describes how many kids will be on each team?
Answers
Answer: The answer is one will have 8 and one will have 9 so roughly 8
Step-by-step explanation
So to start we need to add all the kids together that are playing
5+12= 17
Now we need to divide the number of kids by the number of teams that there are
17 divided by 2=8.5
So each team will have 8 but one will have nine
Hope this helps :D
Answer:
see explanation.
Step-by-step explanation:
5 + 12 = 17.
There are 2 teams.
17 / 2 = 8 R1.
The remaining child has to wait for the game to end.
8 kids will be on each team.
The remaining one will wait.

Answer:
Area of rectangle : 16 square units
Area of triangle : 6 square units
Area of figure : 22 square units
Step-by-step explanation:
The area of a rectangle = length x width
Here, the length of the rectangle is 4 units as well as the width
This means the area of the rectangle is 4 x 4 = 16 units²
The area of a triangle = ( length of base x height ) / 2
Here, the length of the base is 4 units and the height is 3 units
So the area of the triangle = (4x3)/2 = 12/2 = 6 units²
The area of the figure = sum of the two areas
So the area of the figure is 6 + 16 = 22 units²
Answer:
16 + 6 = 22 units²
Step-by-step explanation:
A square is a special kind of closed figure with four straight sides and four right angles that also has sides that all have equal length. Therefore, we can conclude that: A Square is a special kind of rectangle. Every Square is a rectangle, but not every rectangle is a square
Square Area = W x L or l²
Square Area = 4 x 4 = 16 units²
Triangle Area = 1/2 b x h
Triangle Area = 1/2 4 x 3
Triangle Area = 6 units²
Total Area = just sum
16 + 6 = 22 units²
A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Use the diagram of the equilateral triangle shown below to answer the following questions. Show the work that leads to your answers. a. What is the perimeter of the triangle? b. What is the height, ℎ mm, of the equilateral triangle? Write an exact answer using a square root and an approximate answer rounded to the tenths place.
Answers
Answer:
Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.
Step-by-step explanation:
The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.
For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.
I've enclosed an attachment for that.
