5 0

Answer:

El estudiante obtuvo una calificación de 3.5 en su última evaluación.

Step-by-step explanation:

Dado que un estudiante obtuvo calificaciones de 5,7, 6,2 y 4,6 obteniendo un promedio total de 5 en sus calificaciones, para determinar qué nota obtuvo en la ultima prueba para lograr ese promedio, se debe realizar el siguiente cálculo:

(5.7 + 6.2 + 4.6 + X) / 4 = 5

(16.5 + X) / 4 = 5

16.5 + X = 4 x 5

16.5 + X = 20

X = 20 - 16.5

X = 3.5

Gain finds a skirt that she likes at the store for $45.99. If the tax rate is 5.8%, how much will the shirt cost in all
Aleks04 [339]

Answer:

$48.66

Step-by-step explanation:

The price of a good is the base cost plus tax. We are given the cost of the skirt, so all we need is the amount of tax. To find it, we multiple the cost of the  skirt by the tax rate:

45.99 * 0.058 = 2.67

We now add the tax to the cost of the skirt:

45.99 + 2.67 = 48.66

As you can see, we are adding the price of the skirt to 5.8% of the skirt's price, so we can also solve the problem by simply multiplying the cost by 1.058 as shown below:

45.99 * 1.058 = 48.66

Costs of Attendance
erastovalidia [21]

Answer:

y = 3,224x + 750

Step-by-step explanation:

Assuming the scholarship and grants are applied using the slope intercept form y=mx+b where m is the slope in this case the cost per year attending x the number of years attended and b the y intercept which in this case is the one time fee subtracting 13,774 by 10,550 gives us 3,224.

Since the one time fee is only in place once that would make it the y intercept therefore y=3,224x+750 is the correct answer
