Cars are made in a factory for 24 hours every day.
In the factory a car is made every 209 seconds.

Work out an estimate for the number of cars made in the factory in one year.

Answers

Answer:

6,591,024,000

Step-by-step explanation:

Minutes in 24 hours=1,440

number of seconds in 24 hours=60*1440

=86,400..

number of cars made in each second=209

number of cars made in 86,400 seconds= 18,057,600

24 hours =one day

1 year =365 days

cars made in one year =365*18,057,600

=6,591,024,000

therefore, the number of cars made in one year =

6,591,024,000

The number of cars made in the factory in one year where cars are made for 24 hours every day is 150891.

What is the relation between work and time?

The total time taken is inversely proportional to the rate of work. If a unit of work is done in total n number of days, then the total work done W in a day can is,

[tex]W=\dfrac{1}{n}[/tex]

In a factory, cars are made, where Cars are made for 24 hours every day. As, there is total 60 seconds in one minute and 60 minutes in one hour. Thus, the number of second in 24 hours is,

[tex]24\times60\times60=86400[/tex]

In the factory, a car is made every 209 seconds. Thus, the number of cars made in 86400 seconds (24 hours),

[tex]\dfrac{86400}{209}=431.4[/tex]

There is total 365 days (24 hours) in one year. Thus, the number of cars made in the factory in one year is,

[tex]431.4\times365=150891[/tex]

Thus, the number of cars made in the factory in one year where cars are made for 24 hours every day is 150891.

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*y+3-(4*y+2)=0

olve  :    -2y+1 = 0

Step-by-step explanation:

if a polynomial is divided by x-5, the quotient is 2x^2 +8x-9 and the remainder is 3 what is the original polynomial?

Answers

Answer:

[tex]P(x)=2x^3-2x^2-49x+48[/tex]

Step-by-step explanation:

Let the original polynomial be [tex]P(x)[/tex].

We know that when it is divided by [tex](x-5)[/tex], the quotient is [tex]2x^2+8x-9[/tex] and we get a remainder of 3.

Therefore, this means that:

[tex]\frac{P(x)}{x-5}=2x^2+8x-9+\frac{3}{x-5}[/tex]

Remember what it means when we have a remainder. Say we have 13 divided by 3. Our quotient will be 4 R1, or 4 1 over 3. We put the remainder over the divisor. This is the same thing for polynomials.

So, to find our original polynomial, multiply both sides by [tex](x-5)[/tex]:

[tex](x-5)\frac{P(x)}{x-5}=(x-5)(2x^2+8x-9+\frac{3}{x-5})[/tex]

The left side will cancel. Distribute the right:

[tex]P(x)=2x^2(x-5)+8x(x-5)-9(x-5)+\frac{3}{(x-5)}(x-5)[/tex]

Distribute:

[tex]P(x)=(2x^3-10x^2)+(8x^2-40x)+(-9x+45)+(3)[/tex]

Combine like terms:

[tex]P(x)=(2x^3)+(-10x^2+8x^2)+(-40x-9x)+(45+3)[/tex]

Evaluate:

[tex]P(x)=2x^3-2x^2-49x+48[/tex]

And we're done!

Answer: 2x^3 - 2x^2 - 49x + 48

Explanation:

Let a be the original polynomial

Where a/(x-5) = 2x^2 + 8x - 9 (remainder 3)

a = (2x^2 + 8x - 9)(x-5) + 3
a = 2x^3 - 10x^2 + 8x^2 - 40x - 9x + 45+3
a = 2x^3 - 2x^2 - 49x + 48

The area of the circle is 144π m2

What is the diameter of the circle?

Answers

Answer:

Step-by-step explanation:

Remember that

Area of Circle = [tex]\pi r^2[/tex]

[tex]\pi = pi \\r = radius[/tex]

They told us that for this circle, the area is [tex]144\pi m^2[/tex]

If you put it back into the formula for area of a circle we get:

Area of Circle = [tex]\pi r^2[/tex]

[tex]144\pi = \pi r^2[/tex]

Divide both sides by [tex]\pi[/tex].

144 = [tex]r^2[/tex]

Now we want to solve for r (r = radius).

You need to square root each side

[tex]\sqrt{144} = \sqrt{r^2}[/tex]

[tex]12 = r[/tex]

So now we know the radius, [tex]r = 12[/tex] metres

Also remember that

Diameter = [tex]2r[/tex]

So,

Diameter = 2 times 12 = 24 metres

The required diameter of the given circle is 24 meters.

What is an area circle?

The area of the circle is given by the pie times square of the radius.

Area of circle = πr^2

Here,
The given area of the circle is 144π m²
And we know that,
Area = πr²

substitute the value of the area in the above expression,

144π = πr²
r² = 144
r = √144
r = 12 meters

Since,
Diameter = 2 × radius
Diameter = 2 × 12 = 24 meter

Thus, the required diameter of the given circle is 24 meters.

In the diagram shown below PS is perpendicular to RT and the two lines intercept at W. Ray WQ is drawn. Which of the following statements about angle pairs in incorrect?

Answers

Answer:

D. angle SWT and angle QWT are complementary

Step-by-step explanation:

The angles formed at W when the two lines, PS and RT, which are perpendicular to each other intercept at W are right angles.

Thus, let's analyse each given statements to see which is true or not true about the angle pairs formed:

Statement 1: "angle PWQ and angle QWT are complementary".

m<PWT = 90°.

m<PWQ + m<QWT = m<PWT (angle addition postulate)

m<PWQ + m<QWT = 90° (definition of complementary angles)

Therefore, statement 1 is CORRECT.

Statement 2: "angle PWR and angle TWP are supplementary".

m<PWR = 90°

m<TWP = 90°

m<PWR + m<TWP = 180° (definition of supplementary angles)

Therefore, statement 2 is CORRECT.

Statement 3: "angle RWQ and angle TWQ are supplementary".

<RWQ and <TWQ are angles on a straight line and are a linear pair.

m<RWQ + m<TWQ = 180° (definition of supplementary angles)

Therefore, statement 3 is CORRECT.

Statement 4: "angle SWT and angle QWT are complementary".

m<SWT = 90°

Therefore, m<SWT + m<QWT ≠ 90°

The sum of both angles does not give 90°. Therefore, statement 4 is INCORRECT.

3/4 / 2/3 is 9/8 which is 1 1/8. When you did ode fractions you use “KFC” Keep the first fraction the same you Flip the sign from divide to multiply and you change the last fraction by flipping the numerators and denominators around

The value of his hiking speed in miles per hour will be;

⇒ Speed = 9/16 miles per hour

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Jerome hiked 3/4 of a mile in 2/3 of an hour.

Now,

Since, Jerome hiked 3/4 of a mile in 2/3 of an hour.

Hence, We can formulate;

⇒ Speed = Distance / Time

⇒ Speed = 3/4 / 2/3

⇒ Speed = 3×3 / 4×4

⇒ Speed = 9/16 miles per hour

Thus, The value of his hiking speed in miles per hour will be;

⇒ Speed = 9/16 miles per hour

Choice​ 1: 15​-year fixed rate at 6​% with closing costs of ​$1200 and no points. Choice​ 2: 15​-year fixed rate at 5.5​% with closing costs of ​$1200 and 4 points.


What is the monthly payment for choice​ 1? ​$


​(Do not round until the final answer. Then round to the nearest cent as​ needed.)

Answers

Answer:

Monthly payment for choice​ 1 is $6,600

Step-by-step explanation:

We will use following formula in order to calculate the monthly payment of choice 1

Value of Loan = Monthly payment x ( 1 - ( 1 + Interest rate )^-numbers of payments / interest rate

Where

Value of Loan = $110,000

Interest rate = 6%

Numbers of Payment = 15 years x 12 payments / year = 180 payments

Placing values in the formula

$110,000 = Monthly payment x ( 1 - ( 1 + 6% )^-180 ) / 6%

$110,000 = Monthly payment x 16.6662

Monthly Payment = $110,000 / 16.6662

Monthly Payment = $6,600.18

Monthly Payment = $6,600 (Rounded to whole number)

. During a volleyball training session, Idalie drank twice as much water as Adamaris, and Jonathan
Arank 100 mL more water than Idalie. Between them they drank 3 liters of water. How much water
did Adamaris drink?

Answers

Answer:

Step-by-step explanation:

Let's say I = amount of water Idalie drank,

A = amount of water Adamaris drank

J = amount of water Jonathan drank.

We are told Idalie drank twice as much water as Adamaris. You can write it as:

Idalie = 2 times Adamaris

I = 2A

Then we are told Jonathan drank 100ml more than Idalie. So

Jonathan = 100 + Idalie

J = 100 + I  (and we know I = 2A)

J = 100 + 2A

Between them they drank 3 liters (3L = 3000ml) of water.

Idalie + Adalie + Jonathan = 3000

I + A + J = 300

So since we know I = 2A and J = 100 + 2A, we can put it into the equation above:

2A + A + 100 + 2A = 3000

Gather the like terms and you get:

5A + 100 = 3000

Subtract 100 from both sides.

5A = 3000 - 100 = 2900

To find A, divide both sides by 5

A = 2900/5 = 580

This means Adamaris drank 580ml of water
