  (b)  Subtract the total deductions from the gross pay

Step-by-step explanation:

The term "net pay" is applied to the pay after deductions are subtracted. It is also called "take-home pay."

The pay computed based on earnings, commissions, credits, and bonuses, before any deductions, is called the "gross pay."

  net pay = gross pay - deductions

Net pay is calculated by subtracting total deductions from gross pay.

Answer:

15%

Step-by-step explanation:

Percent increase in the original price of jacket = 15%

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given,

Original price of jacket = $110

Increased price of jacket = $126.5

Increased amount = $126.5 - $110

                               = $16.5

Increased amount in percentage = ($16.5/$110) × 100

                                                       = 0.15 × 100

                                                       = 15%

Hence, 15% is increase in the original price of jacket.

Answer:

b = 4.4 feet

Step-by-step explanation:

To find the value of "b", all you need to do is plug the values for "a" and "c" into the pythagorean Theorem and isolate "b".

a² + b² = c²            <------ Phythagorean Theorem

9² + b² = 10²         <------- Plug in a = 9 and c = 10

81 + b² = 100        <-------- Square both values

b² = 19                  <-------- Subtract 81 from both sides

[tex]\sqrt{b^{2} } = \sqrt{19}[/tex]            <-------- Square root both sides to remove exponent

b = 4.358...

b:

XVR = WVS = 125°

RVS = 55°

RST = VSU = 110°

RSV = UST= 70°

Step-by-step explanation:

a:

According this is a Right Triangle ( BCA = 90°) and the sum angles of a triangle is 180° :

90+5x+9x+6=180

14x=84

x=6

Then we have : ABC = 9(6)+6 =60

CBA = 5(6)=30

Answer:

  406.3 cm²

Step-by-step explanation:

The total surface area is the sum of the base area and the lateral area. The lateral area is the sum of the areas of the 6 congruent triangular faces.

__

Each triangular face has a base of 8 cm and a slant height of 10 cm. Its area is ...

  A = 1/2bh

  A = 1/2(8 cm)(10 cm) = 40 cm²

Then the area of 6 faces is 6×40 cm² = 240 cm².

The base area is given.

The total area is the sum of the lateral area and the base area:

  total area = 240 cm² +166.3 cm² = 406.3 cm²

The surface area is about 406.3 cm².

The speed when the power is 2000watts is 22.5m/s

If the power, P (watts), of a car engine is proportional to the square of its

speed, s(m/s), this is expressed as:

P = k/s

When s=25, P=1800 then;

1800 = k/25
k = 25 * 1800
k = 4500

In order to calculate the speed when the power is 2000;

s = k/p
s= 4500/2000
s = 22.5m/s

Hence the speed when the power is 2000watts is 22.5 m/s

Step-by-step explanation:

7km/hr and 13km/hr

Because in this case we divide the total time taken will be 10km/hr but according to the question we have to subtract 3km/hr and also have to add 3km/hr. There for there for there average speed of friends with wind was 7km/hr and friends without wind will be 13km/hr.

Answer:

10.8 km/h to the nearest tenth.

Step-by-step explanation:

Let x be the average with no wind.

Speed = distance / time

With the wind:

x + 3 = 15 / t           A        where t = time in hours for the first half of journey

Against the wind:

x - 3 = 15/(3 - t)       B

Subtract A - B:

6 = 15/t - 15(3 - t)

6t(3 - t) = 15(3 - t) - 15t

18t - 6t^2 = 45  - 30t

6t^2 - 48t + 45 = 0

2t^2 - 16t + 15 = 0

t = - 1.085

So average speed (from equation B)

x = 15/ (3 - 1.085) + 3

  = 10.8 km/h to the nearest tenth.

To graph this on a number line, we'll have open holes at -7 and -1. Then shade between those open holes to complete the graph. The open holes tell the reader "do not include the endpoint". The x values span from -7 to -1, excluding both endpoints. Use of filled in holes, or closed endpoints, will signal that we include the endpoint.  

The answer in interval notation is (-7, -1) which unfortunately looks identical to ordered pair notation. The parenthesis tell the reader to exclude the endpoints. If you wanted to include the endpoint, then use a square bracket instead.

Answer:

3y = -2x + 1

Step-by-step explanation:

Equation of given line is 2y = 3x + 2

==> y = (2/2)x + 1

Slope = 3/2

Slope of perpendicular line is negative of reciprocal of given line ie slope = -2/3

So equation of perpendicular line is of the form

y = (-2/3)x + c where c is a constant

Given that this passes thru x= -1, y =1 we can substitute these values in the above to get

1  =  (-2/3)(-1) + c
This yields 1 = (2/3) + c or c = 1-2/3 = 1/3

So the equation of the perpendicular line is

y = (-2/3)x + 1/3

3y = -2x + 1
