A satellite's speed is
10,000 m/s. After 1
minute, it is 5,000 m/s.
What is the satellite's
acceleration?
Answers
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]

The sum of two numbers is 97. The larger number is three less than four times the smaller number. Find the numbers.
Answers
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.

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.
Answers
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
Answers
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.

Is my answer right? I think it’s A, but I don’t want to get it wrong.
Answers
In right triangle ABC, A = 42°. Find the measure of B which is the other non
right angle.
Answers
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

What is the slope of a line perpendicular to the line whose equation is
x+ 2y = –16. Fully reduce your answer.
Answers
Answer:
slope = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
x + 2y = - 16 ( subtract x from both sides )
2y = - x - 16 ( divide all terms by 2 )
y = - [tex]\frac{1}{2}[/tex] x - 8 ← in slope- intercept form
with slope m = - [tex]\frac{1}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2
