b. If some amount of water contains 1400 oxygen atoms, how many hydrogen atoms does it contain?
hydrogen atoms
Preview
c. If some amount of water contains 3380 oxygen atoms, how many hydrogen atoms does it contain?
hydrogen atoms
Preview
d. Write a formula that expresses the number of hydrogen atoms (y) in any time amount of water in terms of the number of oxygen atoms
that amount of water.
Answer:
B: 2800 hydrogen atoms
C: 6760 hydrogen atoms
D: y=amount of oxygen atoms*2
Step-by-step explanation:
B: We know the formula for water is H2O. SO that means that there is 2 hydrogen atoms and 1 oxygen atom. So there is 2 times the amount of hydrogen atoms so we can do 1400*2=2800, So there is 2800 hydrogen atoms in the water.
C: Same thing as B. 3380*2=6760
D: y=amount of oxygen atoms*2. Because there is one oxygen atom and two hydrogen atoms so 1*2=2.
The table below shows the amount of money Sarah spends for a craft demonstration. Number of People Attending Cost 5 $15 8 $18 10 $20 15 $25 Sarah spends a total of $60. Based on the information in the table, how many people attended the craft demonstration? 20 30 50 70
Answer:
Nobody who paid $18 attended, because that can't be part of $60.
Step-by-step explanation:
4 at $15
10 at $20
15 at $25
=
29 people.
There are 30 people was attended the craft demonstration.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have been given that number of people attending at respective costs as 5 at $15, 8 at $18, 10 at $20, 15 at $25
Since Sarah spends a total of $60.
As per the condition,
So the number of people who attended the craft demonstration attending at respective costs would be 5 at $15, 10 at $20, and 15 at $25
⇒ 5 + 10 + 15 = 30
Thus, the required number of people would be 30 because $18 can't be included in $60, anyone who paid that amount attended.
Therefore, there are 30 people was attended the craft demonstration.

What is the measure of angle SRW
Answer:95
Step-by-step explanation:
In right triangle ABC, A = 42°. Find the measure of B which is the other non
right angle.
A=42
C=90
B=48
We can reason that C will be equal to 90 since it is the right angle. So to find B we have to subtract 90 from 180 to get 90 then subtract 42 to get 48
B=48 degrees

The sum of two numbers is 97. The larger number is three less than four times the smaller number. Find the numbers.
Answer:
20 and 77
Step-by-step explanation:
4x-3+x=97
5x-3=97
5x=97+3
5x=100
x=20
Have a NICE day
The larger number is 77 and the smaller number is 20.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, The sum of two numbers is 97.
Assuming the numbers to be a and b.
∴ a + b = 97...(i)
Also given, The larger number is three less than four times the smaller number,
Assuming the larger number to be a, therefore a = 4b - 3...(ii)
Substituting the value of a in eqn(i) we get,
4b - 3 + b = 97.
5b = 100.
b = 20, hence a = 77.

Point O is on line segment NP. Given OP = 10, NP = 2x, and NO = x +7,
determine the numerical length of NO.
Answer: NO =
Answer:
Given : NP is a line segment
and O is the mid point
therefore, we can write
NP = NO + OP
now put the values
under NP write 2x , NO = x+7 , OP = 10
Therefore the equation that comes to us after putting values is
2x = x+7 + 10
now solving
2x - x = 7+10
x = 17
therefore
numerical length of NO = x+7
i.e. , 17 + 7 = 24

what is the21st term of -3,2,7
Answer:
102
Step-by-step explanation:
The first step is to find out how to find the next number in the term.
In this we can see that to get to the next number in the term we need to add 5.
The easiest way to figure out the 21st term of this, would be to multiply 5×21. This is equal to 105.
But since we started at three less than 5, we need to subtract 3 from 105. 105-3=102.
The 21st term is 102.
A satellite's speed is
10,000 m/s. After 1
minute, it is 5,000 m/s.
What is the satellite's
acceleration?
Answer:
-83.33 [tex]m/s^2[/tex]
Step-by-step explanation:
Given that:
Initial speed of satellite = 10,000 m/s
Final speed of satellite = 5,000 m/s
Time taken = 1 minute
Let us convert it into seconds.
Time taken = 1 minute = 60 seconds
Let us have a look at the formula:
[tex]v=u+at[/tex]
where [tex]v[/tex] is the final speed
[tex]u[/tex] is the initial speed,
[tex]t[/tex] is the time taken and
[tex]a[/tex] is the acceleration
[tex]5000=10000+a\times 60\\\Rightarrow 60a = 5000-10000\\\Rightarrow 60a = -5000\\\Rightarrow a = -\dfrac{5000}{60}\\\Rightarrow \bold{a = -83.33\ m/s^2}[/tex]
Negative sign indicates that the satellite is in slowing down motion i.e. its speed is decreasing.
So, the answer is:
-83.33 [tex]m/s^2[/tex]

Can you me do the work
Answer:
-2 =y
Step-by-step explanation:
-12 = 2 + 5y + 2y
Combine like terms
-12 =2+7y
