The Value of 20/4+8/3

Firstly ,we need to find out the LCM of the denominators

12

Now,

We've to Multiply the numerator with the number which is divisible by the resulting LCM from the respective denominator

just like ,here ,12/4 = 3 so we'll Multiply 3 by the numerator of 4 i.e 20 => 20*3 = 60

We'll apply the same thing with the other one

12/3=4 => 4*8 = 32

Now ,we will add the resulting numerators and will keep it in a fraction with the denominator = LCM of 4&3=12

60+32/12

Answer:

$8460

Step-by-step explanation:

So for this problem we will use the base price of $8000 and add the additional cost of the 5.75% to find the total cost for the car.

So, to find the 5.75%, we simply multiply 8000 by .0575 to get 460.

So 8000 + 460 = 8460.

Thus, the total price of the car would be $8460.

Cheers.

Answer: $8,460

Step-by-step explanation: If you multiply the cost of the car by the sales tax you get your answer. Hope this helps!

The perimeter of a rectangle is equal to 30.

The rectangle is a quadrilateral.  The classification for quadrilaterals is given by the length of sides and angles. For a rectangle,  the opposite sides are equal and parallel and their interior angles are equal to 90°.

A rectangle is a geometric figure that has 4 sides called: length and width (W). Due to its characteristics, the rectangle presents two length (L) and two widths (W).

The perimeter is the sum of all sides of a geometric figures. For a rectangle, the perimeter is 2L+2W.

The area for a rectangle is given by A=L*W.

The question gives:

From the area, you can find the width, see below.

A=L*W

A=2W*W

50=2W²

25=W²

5=W

If W=5, from condition length = 2*W, you can find the length. See

L=2*W

L=2*5

L=10

Therefore, the perimeter will be:

P=2L+2W

P=2*10+2*5

P=20+10

P=30

Answer:

11x = 19

Step-by-step explanation

5x + 2y = 5  and 3x - y = 14

5x + 2(3x -14) =5 and y = 3x -14

5x + 6x -  28 = 5 and  y = 3x -14

11x = 33  and y = 3x -14

x = 3 and y = 3 x 3 -14 = -5

11x =19 <=> x = 11/19 (F)

11x = 33 <=> x= 3 (T)

11y = -55 <=> x= -5 (T)

a) The regular expression "+" represents the language of one or more occurrences of the symbol "+". To construct a grammar that represents the same language but is not regular, we can use the following production rule:

S -> "+" S | "+".

This grammar generates strings with one or more "+" symbols.

b) The regular expression "+c" represents the language of one or more occurrences of the symbol "+" followed by the symbol "c". To construct a non-regular grammar for this language, we can use the following production rules:

S -> "+" S | "c".

This grammar generates strings with one or more "+" symbols followed by a "c". Since the language represented by the regular expression is regular, it can be recognized by a finite automaton. However, the grammar we constructed is not regular because it uses a recursive production rule.

Answer:

33 degrees

Step-by-step explanation:

This is a right angle, meaning that there is a 90 degree angle. If you know that there is a 57 degree part, then you just have to subtract now.

Since there are 90 degrees, you will subtract 57 from 90. As you subtract, you find that 33 is the difference. Now to check your work, add 33 to 57 to see if it is 90, your full angle.

-------------------------------------------------------------------------------------------------------------

90: Full angle

The value of 'a1' is 0.

Let's denote the first term of the geometric series as 'a' and the common ratio as 'r'. The sum of an infinite geometric series can be calculated using the formula:

Sum = a / (1 - r)

We are given that the sum of the infinite geometric series a1, a2, a3, ... is 7. Therefore, we have:

7 = a / (1 - r) ---- (Equation 1)

Now, let's consider the sum of the infinite geometric series a2, a4, a6, ....

The first term of this series is a2 = ar, the second term is a4 = ar^3, the third term is a6 = ar^5, and so on.

The sum of this series can be calculated as:

Sum = (ar) / (1 - r^2)

We are given that the sum of this series is 3. Therefore, we have:

3 = (ar) / (1 - r^2) ---- (Equation 2)

Now, we can solve these two equations simultaneously to find the values of 'a' and 'r'.

From Equation 2, we can rewrite it as:

3(1 - r^2) = ar

Expanding and rearranging:

3 - 3r^2 = ar

3 = ar + 3r^2 ---- (Equation 3)

Now, substitute the value of 'ar' from Equation 3 into Equation 1:

7 = (ar) / (1 - r)

Multiplying both sides by (1 - r):

7(1 - r) = ar

Expanding:

7 - 7r = ar

7 = ar + 7r ---- (Equation 4)

Now, we have two equations (Equation 3 and Equation 4) with two variables ('a' and 'r'). We can solve these equations simultaneously.

Subtract Equation 4 from Equation 3:

3 = ar + 3r^2 - (ar + 7r)

3 = ar - ar + 3r^2 - 7r

3 = 3r^2 - 7r

Rearranging:

3r^2 - 7r - 3 = 0

This is a quadratic equation. We can solve it by factoring, completing the square, or using the quadratic formula. After solving the quadratic equation, we find two possible values for 'r': r = 1 or r = -3/2.

Now, we can substitute these values of 'r' back into Equation 4 to find the corresponding values of 'a'.

For r = 1:

7 = a(1) + 7(1)

7 = a + 7

a = 0

For r = -3/2:

7 = a(-3/2) + 7(-3/2)

7 = -3a/2 - 21/2

42 = -3a - 21

3a = -63

a = -21

Therefore, the two possible values for 'a' are 0 and -21.

However, since we are looking for the value of 'a1' (the first term of the geometric series), the value of 'a' should be positive. Thus, the value of 'a1' is 0.

The slope of the tangent line to a curve is given by f'(x) = 4x² + 3x – 9The equation of the curve is f(x) = (4/3)x³ + (3/2)x² - 9x + 4.

To find the equation of the curve, we need to integrate the given expression for f'(x). Integrating f'(x) will give us the original function f(x).
So, let's integrate f'(x) = 4x² + 3x – 9:
f(x) = ∫(4x² + 3x – 9) dx
f(x) = (4/3)x³ + (3/2)x² - 9x + C
where C is the constant of integration.
Now, we need to use the fact that the point (0,4) is on the curve to find the value of C.
Since (0,4) is on the curve, we can substitute x = 0 and f(x) = 4 into the equation we just found:
4 = (4/3)(0)³ + (3/2)(0)² - 9(0) + C
4 = C
So, the equation of the curve is:
f(x) = (4/3)x³ + (3/2)x² - 9x + 4
Answer:
The equation of the curve is f(x) = (4/3)x³ + (3/2)x² - 9x + 4.

Step-by-step explanation:

The work done in pulling the rope up 20 ft is 101.43 ft-lbs.

To find the work done in pulling the rope up 20 ft, we need to first determine the initial potential energy of the rope before it is lifted up. We can do this using the formula:

Potential Energy = weight * height

where weight is the weight of the rope and height is the distance the rope is hanging from.

Given:

Length of the rope (L) = 70 ft

Weight of the rope (Wt) = 49 lbs

Height of the building (H) = 100 ft

Height to which the rope is lifted (h) = 20 ft

Using the Pythagorean theorem, we can find the distance (d) the rope is hanging from the building:

d^2 = H^2 + L^2

d^2 = 100^2 + 70^2

d^2 = 10000 + 4900

d^2 = 14900

d = \(\sqrt{14900}\)

d = 122.07 ft

Now we can find the initial potential energy of the rope:

Potential Energy = Wt * d

Potential Energy = 49 * 122.02

Potential Energy = 5981.43 ft-lbs

Next, we need to find the final potential energy of the rope after it is lifted up 20 ft. The height to which the rope is lifted is (H + h) = 100 + 20 = 120 ft. Using the same formula as before, we get:

Final Potential Energy = Wt * (H + h)

Final Potential Energy = 49 * 120

Final Potential Energy = 5880 ft-lbs

Finally, we can find the work done in lifting the rope up 20 ft:

Work Done = Initial Potential Energy - Final Potential Energy

Work Done = 5981.43 - 5880

Work Done = 101.43 ft-lbs

Therefore, the work done in pulling the rope up 20 ft is 101.43 ft-lbs.

The volume of the Vehicle Assembly Building (VAB) at the Kennedy Space Center is 3,666,500 liters.

To convert the volume from cubic meters to liters, we can utilize the conversion factor that 1 liter is equal to 1 cubic decimeter (dm^3). Additionally, we know that 1 dm is equal to 0.1 meter.

Given that the VAB volume is 3,666,500 m^3, we can convert it to liters as follows:

3,666,500 m^3 × (1 dm^3 / 1 m^3) × (1 L / 1 dm^3) = 3,666,500 × 1 × 1 = 3,666,500 liters.
