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?

Answers

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.

3. (1,-2) and (3,-2)

4. (2,3) and (2,1)

5. none of the above

Answers

Answer:

1. (-3,2) and (-1,2)

Step-by-step explanation:

Reflection over x-axis results in coordinate change as follows:

(x, y) → (x, -y), x-coordinate stays as is and y-coordinate changes its sign to opposite

Given points:

A(-3, -2) and B(-1, -2)

The image of AB will have coordinates:

A'(-3, 2) and B'(-1, 2)

Correct choice is 1.

subtract 103 degrees from 180 to get 77, then add 77 and 37 together and subtract by 180
First you have to subtract 180 to 103 and you get 77 because a straight line always add up to 180, then you have to add that 77 to the 37 that is inside of the triangle and you get 114 and then you subtract 180 to 114 and you get 66 because the sum of the angles inside of the triangle is 180 degrees
The final answer is x= 66

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

Answers

Answer:

The answer is 3000 kg

Step-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 kg

Hope 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

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.

Answers

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.
