The division of 463 by 60 yields a quotient of 7 with a remainder of 43.

When we divide 463 by 60, we find:

              60  |   463  |  7

                         420

                      - ______

                            43

So, 463 ÷ 60 = 7 with a remainder of 43

The remainder is 43, which indicates that after dividing 463 by 60 as much as possible, there are 43 units left over.

So, the division of 463 by 60 yields a quotient of 7 with a remainder of 43.

Answer:

Step-by-step explanation:

x^2 + 6x + 8 = 0

(x + 4)(x + 2) = 0

x + 4 = 0

x = -4

x + 2 = 0

x = -2

The solution of quadratic equation by factoring is -4.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

We are given that;

x^2+8=-6x

Now,

To solve the quadratic by factoring, we need to first write it in the standard form: x2+6x+8=0

Then we need to find two numbers that multiply to 8 and add to 6. These are 2 and 4. So we can write the quadratic as: (x+2)(x+4)=0

To find the solutions, we need to set each factor equal to zero and solve for x: x+2=0⟹x=−2

x+4=0⟹x=−4

So the solutions are x=−2

and x=−4

Therefore, by quadratic equations the answer will be -4.

Answer:

y - 4 = 0

Step-by-step explanation:

They give you the y coordinate, 4, and the x coordinate as 0.

Put 4 in as y.

4 - 4 = 0. That means x = 0 and that is right.

To make sure it has a slope of zero, subtract 4 on both sides.

You get : y = 4. This means that the line will be straight and it will have a slope of zero.

Answer:

Mean costing =  $3,768

Step-by-step explanation:

Given:

Mean A(x) = 260

Rate = $10 per feet

Fixed charge = $1,168

Computation:

Assume;

depth = x ft

So,

Cost of company B = 10x + 1,168

So,

Mean costing = 10A(x) + 1,168

Mean costing =  10(260) + 1,168

Mean costing =  2,600 + 1,168

Mean costing =  $3,768

Using the normal probability distribution concept, the probability that Company B would charge more than Company A to drill a well is 0.4146

Company A :

Company B :

Equating the cost ;

3681 = 1168 + 10x

3681 - 1168 = 10x

2513 = 10x

x = 251.3

Company B will charge more than Company A when depth exceeds 251.3 feets

Using the Z - score relation :

P(X > 251.3) = (251.3 - 260) / 40

P(X > 251.3) = -0.2175

Using the normal distribution table :

P(Z > -0.2157) = 1 - P(Z < -0.2157)

P(Z > 0.2157) = 1 - 0.58539

P(Z > 0.2157) = 0.4146

Hence, the probability that Company B would charge more than Company A to drill a well is 0.4146

Step-by-step explanation:

The length of the expert trail is 800 meters. We can find our answer by using given tape diagram and simple mathematical calculations.

What is tape diagram?

A tape diagram is a visual model resembling a piece of tape, that is used to assist with the calculations of ratios and addition, subtraction and commonly multiplication.

Here,

Length of the Beginner trail is 200 meters

And also expert trail is 4 times to Beginner trail.

So, Expert trail = 4 * Length of beginner trail.

     Expert trail = 4* 200

                        = 800 meters.

Hence, we get the answer.

Answer:

89-6^2 = 53 so the third side is

[tex] \sqrt{53} [/tex]

Answer:

[tex]\sqrt{53}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the third side, then

x² + 6² = ([tex]\sqrt{89}[/tex] )² , that is

x² + 36 = 89 ( subtract 36 from both sides )

x² = 53 ( take the square root of both sides )

x = [tex]\sqrt{53}[/tex] ← length of third side

Answer:

Step-by-step explanation: Simplifying

2(3y + -5) + -2 = 3(y + -3)

Reorder the terms:

2(-5 + 3y) + -2 = 3(y + -3)

(-5 * 2 + 3y * 2) + -2 = 3(y + -3)

(-10 + 6y) + -2 = 3(y + -3)

Reorder the terms:

-10 + -2 + 6y = 3(y + -3)

Combine like terms: -10 + -2 = -12

-12 + 6y = 3(y + -3)

Reorder the terms:

-12 + 6y = 3(-3 + y)

-12 + 6y = (-3 * 3 + y * 3)

-12 + 6y = (-9 + 3y)

Solving

-12 + 6y = -9 + 3y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-3y' to each side of the equation.

-12 + 6y + -3y = -9 + 3y + -3y

Combine like terms: 6y + -3y = 3y

-12 + 3y = -9 + 3y + -3y

Combine like terms: 3y + -3y = 0

-12 + 3y = -9 + 0

-12 + 3y = -9

Add '12' to each side of the equation.

-12 + 12 + 3y = -9 + 12

Combine like terms: -12 + 12 = 0

0 + 3y = -9 + 12

3y = -9 + 12

Combine like terms: -9 + 12 = 3

3y = 3

Divide each side by '3'.

y = 1

Answer:

Dasher spent $120, Prancer spent $240, and Cupid spent $360

Step-by-step explanation:

Divide 720 by 2 and you get 360, which was cupids total. There is 360 left. Subtract 360 by 240 because Dasher spent half as much as prancer did. You get 120, which is Dasher's total. The 240 you subtracted is Prancer's total.

Dasher spent is $120, Prancer spent is $240 and Cupid spent is $360.

Given that,

According to the situation, calculation of the given data are as follows,

Let Dasher spent amount be x.

So, Prancer amount is 2x and Cupid amount is 3x.

Now, x + 2x + 3x = $720

6x = $720

x = $120

So, Dasher amount (x) = $120

Prancer amount (2x) = $240

Cupid amount (3x) = $360

Answer:

(x² + 7x + 6) ÷ (x² + 2x + 1)

This should be in the form of a fraction, I just don't know how to format it that way on here.

Step-by-step explanation:

Since your denominators are equal on both fractions, you just need to subtract your numerators.

3x² + 9x + 12 - (2x² + 2x + 6)

When there is a - in front of an expression in parenthesis, you should change the sign of each term in the expression of the numerator being subtracted.

So this:

2x² + 2x + 6

Will become this:

2x² - 2x - 6

This is how it will look:

3x² + 9x + 12 - 2x² - 2x - 6

Now all you have to do is collect the like terms.

3x² and -2x² are like terms so you will add them together: 3x² + (-2x²) = 3x² - 2x² = x²

This is how your numerator should look so far:

x² + 9x + 12 - 2x - 6

Now we move on to the next like terms.

9x and -2x are like terms so we add them together: 9x + (-2x) = 9x - 2x = 7x

This is how your numerator should look so far:

x² + 7x + 12 - 6

Now we move on to the last set of like terms.

12 and -6 are like terms so we add them together: 12 + (-6) = 12 - 6 = 6

This is how your numerator should be now:

x² + 7x + 6

Now all you have to do is put your numerator on top of your denominator which is the same as in the start of your equation (x² + 2x + 1).

You are done! I hope this was clear and you understand :)
