600 kcal, when converted, is equivalent to 2380 BTU, 2.51 x 10^6 joules, and 0.70 kwh.

In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume, etc. to another.

A conversion factor is a number used to change one set of units to another, either by multiplying or dividing.

kcal, BTU, joules, and kwh are all units of energy. To convert kcal to these units, we can use the following conversions:

1 kcal = 3.96567 BTU

1 kcal = 4184 joules

1 kcal = 0.00116222 kwh

Converting 600 kcal to BTU, joules and kwh:

1 kcal = 3.96567 BTU

600 kcal = 600(3.96567 BTU)

600 kcal = 2379.4 BTU ≅ 2380 BTU

1 kcal = 4184 joules

600 kcal = 600(4184 joules)

600 kcal = 2.51 x 10^6 joules

1 kcal = 0.00116222 kwh

600 kcal = 600(0.00116222 kwh)

600 kcal = 0.697333 kwh ≅ 0.70 kwh

The distance an object falls in 3 seconds is 380.16 ft.

According to the question we have been given an equation of the distance that an object falls in t seconds, which is

                       d = [tex]\frac{1}{2} g t^{2}[/tex]

where,    d = distance

               g = 84.48 ft/sec²

                t = time.

We need to find the distance an object falls in 3 seconds. That is we have to find d when t = 3 seconds

Putting the required values  in the above formula we get

      d = [tex]\frac{1}{2} (84.48) (3)^{2}[/tex]

      d = 760.32/2

      d = 380.16 ft

hence the distance an object falls in 3 seconds is 380.16 ft.

The equation to find the number of flyers is 10 x + 30 = 250 and the flyers he will hand over each day is 22.

Number of flyers handed out = 30

Total number of flyers = 250

The equation will be:

30 + 10 x = 250

Solving the equation, we get that:

Subtract 30 from both the sides:

10 x = 250 - 30

10 x = 220

Divide both sides by 10:

x = 220 / 10

x = 22

Therefore, the equation to find the number of flyers is 10 x + 30 = 250 and the flyers he will hand over each day is 22.

The coordinates of the vertices of the image after a reflection

in the x-axis is K(4, 2) , L(6, 1) and M(5, 5).

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

Given:

A KLM has coordinates K(4, -2), L(6, -1), and M(5, 5).

According to given question we have

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).

So,

K(4, -2) can changed to K(4, 2) .

L(6, -1) can changed to L(6, 1).

M(5, 5) can changed to M(5, 5).

Therefore, the coordinates of the vertices of the image after a reflection

in the x-axis is K(4, 2) , L(6, 1) and M(5, 5).

Answer:

=========================

Let the amount of money be x, then, considering she buys more than zero pounds of candy, the total she spends is:

Jane will spend between zero and $30.

Answer:

$0 < x < $30

Step-by-step explanation:

To find:-

Answer:-

We are here given that , Jane buys candies which are $6 per pound . She buys less than 5 pounds on candies .

Now since she purchased some candies therefore, the amount she spent will be greater than " 0 " .

Now she buys less than 5 pounds of candies . Cost of that would be $6*5 = $30 .

Hence she purchased somewhere between them that is between $0 and $30 .

If we denote the amount spent by Jane on candies by "x" , then ; we can represent this situation as ;

[tex]:\implies \sf \pink{ \$ 0 < x < \$30} \\[/tex]

Hence the required answer is " $0 < x < $30 .

Applying the definition of supplementary angles, x = 18; m<PNO = 70°.

If two angles lie on a straight line adjacent to each other, both angles are supplementary, thus, their sum is equal to 180 degrees.

Angle MNO and angle PNO are supplementary angles, therefore:

m<MNO + m<PNO = 180 degrees.

m<MNO = 110°

m<PNO = (3x + 16)°

Substitute

110 + 3x + 16 = 180

126 + 3x = 180

126 + 3x - 126 = 180 - 126

3x = 54

x = 18

m<PNO = 3x + 16 = 3(18) + 16

m<PNO = 70°

Therefore, applying the definition of supplementary angles, x = 18; m<PNO = 70°.

Oil change = $59.99

Brake pads = $40

Radiator flush = $10

Part a:

The price of an oil change is $59.99

The cost of brake pads replacement is $40

The price of a radiator flush is $10

Part b:

Brake pads replacement costs $40

Radiator flush costs $10

Answer:

The correct answer is 64 marbles.

Step-by-step explanation:

Let's analyze the information we have:

Jill has 4 bags of marbles.

In each bag she has 16 marbles (in each one she has 3red, 5green, 2 yellow, and 6black)

If each bag has 16 marbles, and she has 4 bags, then we must multiply the contents of each bag by 4.

And we do it as follows:

16 x 4 = 64

Therefore, we can say that Jill has 64 marbles.

Answer:

There is 16 in each bag so there is 64 marbles in total.

Step-by-step explanation:

3 + 2 = 5

5 + 5 = 10

10 + 6 = 16

16 x 4 (16 + 16+ 16+ 16) = 64

The solution of the quadratic equation is (ii) 0 and 6. (iii) Imran's father was 30 years old when Imran was born.

Quadratic equation in one variable is generally of the form of ax²+bx+c=0 where x is the variable and a, b and c are constants.

The degree of a quadratic polynomial is 2 and there are 2 solutions for a quadratic equations.

The graph of a quadratic equation is parabolic in shape.

Imran's father is x² years  when Imran is x years. So after 4x years:

Imran's father's age=x²+4x

Imran's age=x+4x=5x

Now Imran's father is twice as old as Imran

∴2×(5x)=x²+4x

or, 10x=x²+4x

or, x²-6x=0

Hence the equation reduces to a quadratic equation of the form x²-6x=0.

ii) Solving the quadratic equation:x²-6x=0

Breaking into factors we get:

or, x(x-6)=0

either x=0 or x-6=0 or, x=6

Therefore the solution of the equation is 0,6 .

iii) When x=6 i.e, Imran is 6 years old,

age of his father = x²=6²=36 years.

So when Imran was born 6 years ago age of his father=36-6=30 years old.

The simplified expression of 3/x+1 - 1/x-1 - 2x/x^2+1 is [-2x^3 - 4x^2 + 2x - 2]/[x^4 -  1]

The expression is given as

3/x+1 - 1/x-1 - 2x/x^2+1

Take the LCM of the first two terms

So, we have

(3x - 3 - x - 1)/(x^2 - 1) -  2x/x^2+1

This gives

2x - 4/(x^2 - 1) -  2x/x^2+1

Take the LCM

[(2x - 4)(x^2 + 1) -2x(2x^2 - 1)]/(x^4 - 1)

Expand

[2x^3 - 4x^2 + 2x - 4 - 4x^3 + 2]/[x^4 -  1]

Evaluate the like terms

[-2x^3 - 4x^2 + 2x - 2]/[x^4 -  1]

Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value. By dividing both numbers by the same number, one can convert a division problem into an analogous problem while keeping the ratio between the two numbers constant. The equivalent is defined as something that is almost identical to or equal to another object. Two numbers that are equivalent are (2+2) and 4.
