Determine the mass of an object, if it requires a force of 6,000 kg: m/s2 to accelerate at the rate of 2 m/s^2
Answer:
The answer is 3000 kgStep-by-step explanation:
The mass of an object can be found by using the formula
[tex]m = \frac{f}{a} \\ [/tex]
f is the force
a is the acceleration
From the question we have
[tex]m = \frac{6000}{2} \\ [/tex]
We have the final answer as
3000 kgHope this helps you
[tex] \boxed{ \red{AnswEr:-}}[/tex]
Mass = 3000 kg★ GivEn :-
Force = 6000 kg • m/s^2Acceleration = 2 m/s^2★ To Find :-
The value of mass★ Solution :-
From Newton's 2nd law of motion we get the equation,
[tex]{ \boxed{ \red{ \sf{F =
m \times a}}}}[/tex]
where,
F = Force m = mass of the objecta = acceleration[tex] \implies \sf \: m = \dfrac{F}{a} [/tex]
Putting the values,
[tex] \implies \sf \: m = \dfrac{6000}{2} [/tex]
[tex] \implies \red{\sf \: m = 3000}[/tex]
Therefore, mass of the object = 3000 kg
At a dairy farm the ratio of adult milking cows to young calves was 9:2. If there were 234 adult milking cows at the farm, how many young calves were there?
Answer:
52 young calves
Step-by-step explanation:
At a dairy farm the ratio of adult milking cows to young calves was 9:2. If there were 234 adult milking cows at the farm, how many young calves were there?
The ration is given as:
adult milking cows to young calves
= 9 : 2
= 234 : x
= 9/2 = 234/x
x = Number of young calves
Cross Multiply
9 × x = 2 × 234
= x = 2 × 234/9
x = 468/9
x = 52
Hence, the number of young calves on the farm is 52.

Answer:
it should be b but if i'm wrong im really sorry :(
Step-by-step explanation:
Use the equation p= 8.31/v where p = pressure and V = volume.
What happens to the pressure as the volume approaches 0? Explain your reasoning.
Answer: pressure increases
Step-by-step explanation:
because Boyle's law states that pressure and volume have an inverse relationship, if we decrease volume the pressure will increase.
Another explanation: since volume approaches 0, we're dividing by a smaller number, and doing this gives us a larger value for pressure
Answer:
The pressure approaches infinity.
The function is undefined for V = 0.
There is an asymptote at V = 0.

Which statement is true about 1?
A. It is a prime number.
B. It is a composite number.
C. It is a whole number that is neither prime nor composite.
D. It is not a whole number.
Please dont be greedy and answer the question saying something like "i have no idea" Thanks
Answer:
C. It is a whole number that is neither prime nor composite.
Step-by-step explanation:
A prime number is a number that has two factors: one and another number. Thus, since 1 only has one factor (itself), it cannot be a prime number.
However, a composite number must have more than two factors, which 1 doesn't have either.
Since 1 is a whole number (not a decimal or fraction), and it is neither prime nor composite, the answer would be C.
Have a nice day!

In a survey of 2,200 people who owned a certain type of car, 880 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
*blank*% of the people surveyed were satisfied with the car.
Answer:
40%
Step-by-step explanation:
Given parameters:
Number of people surveyed = 2200
Number of people who said they would buy the car again = 880
Unknown:
The percentage of people satisfied with the car = ?
Solution:
The percentage of people satisfied with the car purchase can be determined using the expression below:
Percentage of people satisfied = [tex]\frac{Number of people who said they would buy the car again}{Number of people surveyed} x 100[/tex]
Percentage of people satisfied = [tex]\frac{880}{2200}[/tex] x 100 = 40%

Anthony read
pages per minute.
Answer: Anthony read 2 pages per minute.
Step-by-step explanation:
Answer: 2 pages/ 1 minute or (2 pages per minute)
Step-by-step explanation: To find the unit rate for how many pages of a book Anthony finds in 23 minutes, you’ll have to divide 46 by 23, which gives you a final result of 2 pages/ 1 minute or (2 pages per minute).
8x+2 factored using the GCF.
My friend is wondering this, I have seen responses but like all are different. Please help!
7th grade math.
Explanation:
For now, ignore the x.
The GCF of 8 and 2 is 2 since 2 is a factor of both
2 = 2*1
8 = 2*4
So if we had 8+2 we can factor 2 out like so to get 2*(4+1)
Notice that I divided each term by 2 when going from 8+2 to 4+1. Then I stuck a 2 outside. You can use the distributive property to check the result.
Similarly,
8x+2 = 2(4x+1)
which you can also check using the distributive property.

The order pairs (1, 2), (2, 5), (3, 10), (4, 17), and (5, 26) represent a function. What is a rule that could represent this function?
A. y = x2 + 1
B. y = x2 − 1
C. y = x2
D. y = x + 1
Answer:
The answer is A
Step-by-step explanation:
1 to the second power is 1 + 1 = 2
2 to the second power is 4 + 1 = 5
3 to the second power is 9 + 1 = 10
4 to the second power is 16 + 1 = 17
5 to the second power is 25 + 1 = 26
y = x² + 1 is a rule that could represent the given function.
Given that,
The order pairs (1, 2), (2, 5), (3, 10), (4, 17), and (5, 26) represent a function, what is a rule that could represent this function is to be determined.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
While observing the pattern of pair it is found that every ordinate is 1 more the square of its abscissa, so the general equation for the function is given as,
y = x² + 1
Thus, y = x² + 1 is a rule that could represent the given function.
