Answer:

y = 2

 5.34

y = -2

- 2.66

Step-by-step explanation:

0.67y + 4

y = 2

.67(2)+2

 1.34+4 = 5.34

y = -2

-.67(2)+2

 -1.34+4 = 2.66

Answer:

2.66 and 4.34

Step-by-step explanation:

To evaluate, substitute the values of y and solve.

So, when y =-2

0.67y + 4 = -1.34 + 4 = 2.66

And when y = 2

0.67y + 4 = 1.34 + 4 = 4.34

Hope this helps.

Robert makes $951 gross income per week and keeps $762 of it after tax withholding. How many allowances has Robert claimed? For
MAXImum [283]

Answer:

Option D,four is correct

Step-by-step explanation:

The tax withholding from the gross income of $951 is the gross income itself minus the income after tax withholding i.e $189  ($951-$762)

The percentage of the withholding =189/951=20% approximately

Going by the multiple  choices provided,option with 4,189 dollars seems to the correct option as that is the exact of the tax withholding on Robert's gross income and his earnings fall in between $950 and $960

El interior de un tanque que contiene agua, tiene una presión manométrica de 300 kPa. ¿Qué profundidad tiene el tanque de agua?
zmey [24]

Respuesta:

30,6 metros

Explicación paso a paso:

Dado :

Presión = 300 Kpa

Usando la fórmula que relaciona la presión y la profundidad:

Presión = profundidad * aceleración debida a la gravedad * densidad del agua

Densidad del agua = 1000 kg / m³

Presión = 300Kpa = 300 * 10 ^ 3 Pa

300 * 10 ^ 3 Pa = profundidad * 9,8 * 1000

300000 = profundidad * 9800

Profundidad = 300000/9800

Profundidad = 30,612

Profundidad = 30,6 m

A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly. When first noticed, t
7nadin3 [17]

To solve this problem, we can use the tan function to find for the distances covered.

tan θ = o / a

Where,

θ = angle = 90° - angle of depression

o = side opposite to the angle = distance of boat from lighthouse

a = side adjacent to the angle = height of lighthouse = 200 ft

When the angle of depression is 16°18', the initial distance from the lighthouse is:

o = 200 tan (90° - 16°18')

o = 683.95 ft

When the angle of depression is 48°51', the final distance from the lighthouse is:

o = 200 tan (90° - 48°51')

o = 174.78 ft

 

Therefore the total distance the boat travelled is:

d = 683.95 ft - 174.78 ft

<span>d = 509.17 ft</span>
