Mario bought a new car for $25,000. The value of the car is decreasing at a rate of 12.5% every year. After 3
maxonik [38]

Answer:

$16,748

Step-by-step explanation:

we know that

The equation of a exponential decay function is equal to

y=a(1-r)^x

where

y is the value of the car

x is the number of years

a is the initial value

r is the rate of change

In this problem we have

a=\$25,000\\r=12.5\%=12.5/100=0.125

substitute

y=25,000(1-0.125)^x

y=25,000(0.875)^x

For x=3 years

substitute

y=25,000(0.875)^3=\$16,748

Overtime pay definition
Marizza181 [45]

In your work field, depending on the comapny, there are a certain amount of hours you can work before going into overtime. Overtime pay is when you work over the minimum corperate set hour base line. Which if you pass that certain number, you get pay and a half. Which basically means your regular hour pay, but another half of it. So say you're making $9 and hour. If you go into overtime, you'd be making $13 an hour. But only in thos overtime hours. So if you worked say 7 hours overtime, you'd make $91 just in those 7 hours.

La pregunta está incompleta:

Observa los puntajes de las respuestas de una evaluación que tuvo de 100 preguntas. Si Alfredo contestó correctamente 57 preguntas, 16 incorrectas y el resto las dejó en blanco, ¿qué puntuación obtuvo en la evaluación?

Puntos por respuesta:

Correctas: 4

En blanco: -1

Incorrectas: -3

Answer:

Alfredo obtuvo una puntuación de 153.

Step-by-step explanation:

De acuerdo a la información proporcionada, conoces el número de preguntas en la evaluación y el número de preguntas que Alfredo contestó de forma correcta e incorrecta y tienes que restar estas del total de preguntas para encontrar el número de preguntas que dejó en blanco:

100-57-16=27

Ahora, debes multiplicar el número de respuestas correctas, incorrectas y en blanco por su respectivo puntaje:

Correctas: 57*4=228

En blanco: 27*(-1)=-27

Incorrectas: 16*(-3)=-48

Finalmente, debes sumar los resultados obtenidos por cada tipo de respuesta:

228+(-27)+(-48)= 228-27-48=153

De acuerdo a esto, la respuesta es que Alfredo obtuvo una puntuación de 153.

The perimeter of a rectangle is 59 59 feet. If the length is 14 14 feet, find the width. Step 3 of 3 : Solve the problem by subs
Alenkasestr [34]
Perimeter = 2L + 2W  where L = length and W = width.

So we have

2*14.14 + 2W = 59.59
2W = 59.59 - 2*14.14
2W = 59.59 - 28.28 = 31.31
W = 31.31 / 2 =  15.66  to 2 decimal places
