Answer:

a). 14 hours a week

b). 10.5 hours a week

Step-by-step explanation:

His time = 42 hours a week

Quarter of his time = one fourth of his time.

Third of his time = one third of his time

So, for dealing with complaints:

42h * 1/3 = 42h / 3 = 14h

On the phone:

42h * 1/4 = 42h / 4 = 10.5h

Answer:

a) 14 hours

b) 10.5 hours

Step-by-step explanation:

42 hours = 1 week

a) 1/3 hours a week dealing with complaints

[tex]\frac{1}{3} *\frac{42}{1} = \frac{42}{3} = 14[/tex]

He spends 14 hours a week dealing with complaints.

b) 1/4 hours a week on the phone

[tex]\frac{1}{4} * \frac{42}{1} = \frac{42}{4} = \frac{21}{2} = 10.5[/tex]

He spends 10.5 hours a week on the phone.

The equation of the axis of symmetry is x = 6

The equation of the parabola is given as:

y = 2x^2 - 24x + 86

Differentiate the equation of the parabola

So, we have

y' = 4x - 24

Set the differentiated equation of the parabola to 0

So, we have

4x - 24 = 0

Add 24 to both sides of the differentiated equation of the parabola

4x = 24

Divide both sides of the differentiated equation of the parabola by 4

x = 6

This represents the the axis of symmetry

Hence, the equation of the axis of symmetry is x = 6

Step-by-step explanation:

Using substitution method, the solution of the given system of equations is (2,3)

A system of equation can be solved using:

The given system of equations:

5m - n = 7  ............   (1)

3 + 3n = 6m  .............. (2)

In equation (1), subtract 5m from both sides:

5m - n - 5m = 7 - 5m

-n = 7 - 5m

Multiply by (-1)

n = 5m - 7  ...... (3)

Substitute  n = 5m - 7 into equation (2)

3 + 3n = 6m

3 + 3(5m - 7) = 6m

15m -18 = 6m

9m = 18

m = 2

Substitute back m = 2 into equation (3)

n = 5m - 7

n = 5.(2) - 7 = 3

Hence, the solution is (2, 3)

Evaluating the expression b(2b - a) for a = 3 and b = -5 is equal to 65.

An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".

To evaluate an expression or an equation means to substitute a value to the variable and perform the arithmetic operations included.

Given the expression b(2b - a), substitute the value of the variable a and the value of variable b.

b(2b - a)

-5[2(-5) - (3)]

Performing the arithmetic operations, we can have the value of the expression.

-5[2(-5) - (3)]

= -5(-10 - 3)

= -5(-13)

A percentage in mathematics is a number or ratio that can be expressed as a fraction of 100.

The percent of the given number 65 % of 360 is 234.

A percentage in mathematics is a number or ratio that can be expressed as a fraction of 100. The term percent comes from the Latin "per centum" which means per hundred. The symbol percentage is used to represent percentage.

Let the equation be 65 % of 360

Percentage = (value/total value) × 100 %.

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have

65 % of 360 = 65/100 of 360

65/100 × 360 = 234

Therefore, the percent of the given number 65 % of 360 is 234.

The distance between them when the force is 36 pounds is 5.06 feet.

According to the statement

We have to find that the distance between two bodies.

So, For this purpose, we know that the

A force is a push or pull upon an object resulting from the object's interaction with another object.

From the given information:

If the force of attraction is 64 pounds when the distance between the bodies is 9 feet

Then

F1 =64 pounds, r1 = 9 ft

F2 = 36 , r2 = ?

The gravitational force of attraction is inversely proportional to the square of distance between the two bodies.

So, F2 / F1 = r1^2 / r2^2

36 / 64 = 9 / r2

r2 = 0.56*9

r2 = 5.06.

y-3=4 x is in point-slope form, it is neither in slope-intercept form nor standard form.

A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane allows one to anticipate whether a line is parallel, perpendicular, or not.

The change in a line's y coordinate relative to its change in x coordinate is referred to as the line's slope. Δy is the net change in the y coordinate, while Δx is the net change in the x coordinate.  

Therefore,

m =  y₂-y₁/x₂-x₁ (where m denotes the slope) can be used to express how the y coordinate changes in relation to the x coordinate.

Be aware that tan ∅ = y/x

We also refer to this tan as the line's slope

We know that  point-slope form = y₂ - y₁ = m(x₂ - x₁)

the equation looks like this in point-slope form ⇒ y-2= 4(x-0)

Here, the points are (x, y) and the points the line is passing through is

(0, 2)

y-2= 4(x-0) is in point-slope form, it is neither in slope-intercept form nor  standard form.

Three angles fit around a point, two of the angles are 115° and 53° , then the size of third angle would be 192° and it would be a reflex angle.

The sum of the angles around a point is 360 °

If the two angles are 115° and 53° , the sum of the two angles would be 168°

If we reduce the sum of the two angles from the total 360° , we get the size of third angle as 192°

As the size of third angle is more than 180° , so the name of the third angle is reflex angle because right angle is measured 90° , obtuse angle is measured more than 90° but less than 180° , reflex angle is measured more than 180° but less than 360° and acute angle is measured less than 90 °
