Step-by-step answer:

Given:

Initial monthly salary = $5000

New salary = 10% less

Salary a year after = 15% more

Solution:

New salary

= 5000 * (100-10)%

= 5000 * 90%

= 5000 * 90/100

= 4500

Salary a year after

= 4500 * (100+15%)

= 4500 * 115%

= 4500 * 115/100

= 45*115

= 5175

Answer:

110.5 yd²

Step-by-step explanation:

Separate the figure into 1 triangle and 3 rectangles.

(see attached image)

<u>Area 1</u>

Area of a triangle = 1/2 × base × height

                             = 1/2 × (7 + 2 + 2) × 7

                             = 1/2 × 11 × 7

                             = 38.5 yd²

<u>Area 2</u>

Area of a rectangle = width × length

                                 = 3 × (5 + 2 + 2)

                                 = 3 × 9

                                 = 27  yd²

<u>Area 3</u>

Area of a rectangle = width × length

                                 = 5 × (5 + 2)

                                 = 5 × 7

                                 = 35  yd²

<u>Area 4</u>

Area of a rectangle = width × length

                                 = 2 × 5

                                 = 10  yd²

<u>Total Area</u>

Area 1 + Area 2 + Area 3 + Area 2 = 38.5 + 27 + 35 + 10

                                                        = 110.5 yd²

HELP PLSSS ASAP!!!!!!!!
neonofarm [45]

Answer:

x = 5.5

Step-by-step explanation:

PM = MR

4x - 12 = -2x + 21         {add 2x to both the sides}

4x - 12 + 2x = -2x + 2x + 21

6x - 12 = 21         {Add 12 to both sides}

6x - 12 + 12 = 21 + 12

            6x  = 33

              x = 33/6

x = 5.5

What is the momentum of each hockey player? Hockey player 1 has a mass of 65 kg and a velocity of 3.8 m/s
DaniilM [7]

Answer:

Momentum of  hocking player 1: 247\ kg\ m/s

Hockey player 2: =249.4\ kg\ m/s

Step-by-step explanation:

For first hockey player :

Given that

mass (m) =65\ kg

Velocity (v) =3.8\ m/s

p=mv\................(1)

where p is momentum

put the value in equation (1)

p=65\times3.8\\\\p=247kg\times m/s

For second hockey player :

Given that

mass (m) =58\ kg

velocity (v) =4.3\ m/s

p=mv\ ...............(2)

Where p is momentum

put the value in equation (2)

p=58\times4.3\\p=249.4\ kg\times m/s
