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.

Answers

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%

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

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.

Answers

Answer:   2(4x+1)

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.

Please dont be greedy and answer the question saying something like "i have no idea" Thanks

Answers

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.

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

Answers

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.

What are functions?

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.

The perimeter of a triangle is 59 cm. The first side is 7 cm shorter than the second side. The third side is 4 cm less than twice the length of the first side. Find length of each side

Answers

Given:

The perimeter of a triangle is 59 cm.

The first side is 7 cm shorter than the second side.

The third side is 4 cm less than twice the length of the first side.

To find:

The length of each side.

Solution:

Let x be the second side.

Then, according to the question,

First side = x-7

Third side = 2(x-7)-4

Perimeter of a triangle is the sum of all of its sides.

[tex](x-7)+x+(2(x-7)-4)=59[/tex]

[tex]x-7+x+2x-14-4=59[/tex]

[tex]4x-25=59[/tex]

Add 25 on both sides.

[tex]4x=59+25[/tex]

[tex]4x=84[/tex]

Divide both sides by 4.

[tex]x=21[/tex]

Now,

First sides =21 - 7=14 cm

Second side = 21 cm

Third side = 2(14)-4 = 24 cm

Therefore, the three sides of triangle are 14 cm, 21 cm and 24 cm respectively.

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.

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.
