Alex accepted a job as a veterinarian that pays a salary of $78,500 in the first year. After the first year, his salary increased by 1.5% per year.

Alex works for the vet clinic for 10 years. What is the total of his earnings over the 10 years?

Round your answer to the nearest hundredth

$ = _______

Answers

Answer:

795.597,5

Step-by-step explanation:

let's consider the fact that Alex worked for the vet for 10 years. First year is off with $78,500 since that was his first payment, now there are nine years left. With some math operations we find that 1,5% in this problem is equal to 1.177,5$. So if we take that number and put it together with Alexs' first payment we get from now and on his yearly pay, which is $79.677,5. At last we take that number multiply it by 9 and add all the numbers together (78,500+79.677,5(×9)= 795.597,5)

The total of his earnings over the 10 years is $236677.5.

What is interest rate?

The percentage increase formula is used to compare the growth in a quantity from the initial value to its final value, over a period of time.

Given

P = $78,500

Interest rate = 1.5 %

Time t = 10 years

Total earning = P[tex](1+\frac{r}{100} )^{t}[/tex]

A = 78500[tex](1+\frac{1.5}{100} )^{t}[/tex]

A = 78500[tex](\frac{1015}{100} )^{10}[/tex]

A = 78500[tex](\frac{230}{200} )^{10}[/tex]

A = $236677.5

Hence, the total of his earnings over the 10 years is $236677.5.

find the difference between 4/11 of 2½ and 3/4​

Answers

Answer:

4/11 of 2 1/2 = 4/11 * 5/2 = 20 / 22 = 10/11

a common denominator of 11 and 4 is 44

So 40 / 44 - 33 / 44 = 7/44

Check 4/11 * 2.5 = .909

3/4 = .75    

difference = .909 - .750 = .159

7/44 = .159

A is the point (-2, 0) and B is the point (0, 4).Find the equation of the straight line joining A and B.

Answers

Answer:

y = 2*x + 4

Step-by-step explanation:

We know that a linear function can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

We know that if this line passes through the points (x₁, y₁) and (x₂, y₂) the slope can be written as:

a = (y₂ - y₁)/(x₂ - x₁)

So, here we know that our line must pass through the points (-2,0) and (0, 4)

Then the slope of this line is:

a = (4 - 0)/(0 - (-2))

a = 4/2 = 2

Then our line is something like:

y = 2*x + b

Now, to find the value of b we can use one of these two points, for example if we use the point (-2, 0), we know that, when x = -2, we must have y = 0.

0 = 2*(-2) + b

0 = -4 + b

4 = b

Then the equation for our line is:

y = 2*x + 4

L Por el alquiler de un coche cobran 100
pesos diarios mas 0.30 centavo por
kilometro. Encuentra la ecuacion de la recta
que relacoma el costo diarlo con el número
de kilometros
y representala.Si en un dia
se ha hecho un total de 300 km, que
importe debemos abonar?

Answers

Answer:

Sabemos que el costo del alquiler es 100 pesos diarios, más 0.30 pesos por kilómetro.

Entonces, solo por alquilar el coche por un día, hay que pagar 100 pesos.

Si además lo conduces x kilómetros, tendrás que pagar x veces 0.30 pesos.

Entonces el costo diario, en pesos, será:

C(x) = 100 + 0.30*x

Para graficar esta ecuación simplemente se deben encontrar dos pares:

(x, C(x)) en un eje de coordenadas, y luego conectarlos con una línea.

Por ejemplo, si tomamos:

x = 0

C(0) = 100 + 0.30*0 = 100

entonces tenemos el par (0, 100)

si x = 10

c(10) = 100 + 0.30*10 = 100 + 3 = 103

entonces tenemos el par (10, 103)

Ahora podemos graficar esos dos puntos y conectarlos con una línea, como en el ejemplo de abajo.

b)  

También queremos conocer el costo diario si se han hecho un total de 300km.

Entonces simplemente reemplazamos x por 300 en la ecuación del costo:

C(300) = 100 + 0.30*300 = 100 + 90 = 190

El costo será de 190 pesos.

El dinero total a pagar por 300 Km es de 190 pesos.

La ecuación de una recta viene dada por y = mx + c

m = pendiente

c = intersección

Así, dado que cobran 100 pesos por día más 0,30 centavos por kilómetro, podemos escribir;

y = 100 + 0,30 x

Dado también que hay un total de 300 km, ahora tenemos;

y = 100 + 0.3(300) = 190 pesos

[tex]y-9=17(x+7)[/tex]

Step-by-step explanation:

Hi there!

What we know:

The line goes through the points (-8,-8) and (-7,9)We need to write the equation of the line in point-slope form

What we need to know:

Point-slope form: [tex]y-y_1=m(x-x_1)[/tex] where m is the slope of the line and [tex](x_1,y_1)[/tex] is a point that the line passes throughWe're given "[tex]y-9=[/tex]", which is the "[tex]y-y_1[/tex]" part of the point-slope form equation. This means that [tex](x_1,y_1)[/tex] is [tex](-7,9)[/tex] and we only need to solve for m.

Our equation so far (plugging in the point (-7,9):

[tex]y-9=m(x-(-7))[/tex]

[tex]y-9=m(x+7)[/tex]

Determine the slope (m)

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the given points (-8,-8) and (-7,9)

[tex]=\frac{-8-9}{-8-(-7)}\\=\frac{-8-9}{-8+7}\\=\frac{-17}{-1}\\= 17[/tex]

Therefore, the slope of the line is 17. Plug this into [tex]y-9=m(x+7)[/tex]:

[tex]y-9=17(x+7)[/tex]

Shelly purchased 6 25'-tape

$78. Sean purchased one 25'-tape
measure and 3 chalk line reels from
the same store for $29. What was
the price of each 25'-tape measure
and each chalk line reel?

Answers

Answer:

Price of one 25'-tape measure = $11

Price of one chalk line reels = $6

Step-by-step explanation:

Let t = price of one 25'-tape measure, and

let c = price of one chalk line reel

"Shelly purchased 6 25'-tape measures and 2 chalk line reels for $78."

6t + 2c = 78

"Sean purchased one 25'-tape measure and 3 chalk line reels ... for $29."

t + 3c = 29

We have a system of two equations in two variables. We will solve it with teh substitution method.

Solve the second equation for t.

t = 29 - 3c

Substitute 29 - 3c for t in the first equation.

6(29 - 3c) + 2c = 78

174 - 18c + 2c = 78

-16c = -96

c = 6

Substitute 6 for c in the second original equation.

t + 3(6) = 29

t + 18 = 29

t = 11

Answer:

Price of one 25'-tape measure = $11

Price of one chalk line reel = $6

Which expression is equivalent to  4 7/8 ÷ 4 1/4​

Answers

Answer:

Improper fraction: 39/34

Proper fraction: 1 5/34

Decimal: 1.147 (rounded to the nearest thousandths).

Step-by-step explanation:

Solve each expression given, if it has the same result, then the expressions is equivalent. Solve the given expression:

4 7/8 ÷ 4 1/4

First, change all fractions into improper fractions:

4 7/8 = (4 * 8)/8 + 7/8 = 32/8 + 7/8 = 39/8

4 1/4 = (4 * 4)/4  + 1/4 = 16/4 + 1/4 = 17/4

Next, find common denominators. Note that what you do to the denominator, you must do the numerator:

(17/4) * (2/2) = (34/8)

39/8 ÷ 17/4

Solve. First, change the division sign into multiplication, and then flip the second fraction:

39/8 ÷ 17/4 = 39/8 x 4/17

Multiply straight across:

39/8 x 4/17 = (39 x 4)/(8 x 17) = 156/136 = 39/34 (simplified), or 1 5/34.
