The currency in Argentina is the Peso. The exchange rate is approximately $3 = 1 Peso. At this rate, how many Pesos would you get if you exchanged $121.10?

Answers

3dollars/1=121.10dollars/x
3x=121.10
x=40.67

The answer is 40.67 dollars

Hope this helps
Final answer:

The Pesos you would get if you exchanged $121.10 using an exchange rate of $3 = 1 Peso, you can set up a proportion and solve for x.

Explanation:

To calculate how many Pesos you would get if you exchanged $121.10 at an exchange rate of $3 = 1 Peso, you can set up a proportion:

$3 / 1 Peso = $121.10 / x Pesos

Cross multiply to solve for x:

$3 * x = $121.10 * 1

x = $363.30

Therefore, you would get 363.30 Pesos if you exchanged $121.10 at the given exchange rate.

Find the take-home percent of the gross pay: net pay $453.10, gross pay$734

50%

16%

162%

62%

Answers

453.10/734 = .617% * 100 = 61.7% --> 62%

D. 62%

Answer:

Option D. 62%

Step-by-step explanation:

Net pay = $453.10

Gross pay = $734.00

We have to find the take-home percent of the gross pay.

We will divide net pay by gross pay and multiply by 100.

Percent of the gross pay =  [tex]\frac{453.10}{734}\times 100[/tex]

                                         = 0.617302452 × 100

                                         = 61.73 ≈ 62%

The take-home percent of the gross pay would be 62%.

Me. Driscoll has 9 reports to grade. There are 6 page for each report. He grades 12 pages. How many pages does he still have to grade?

Answers

so easy

so driscoll has 9 reports to grade and each page has 6 pages.

just multiply 9 and 6 which gives you your answer 54.

so out of 54, he has graded only 12 pages which means that you need to subtract.

[tex]54-12=42[/tex]

driscoll has 42 pages left to grade.

you can recheck your answer by adding 42 ans 12 which gives your answer as 54. so yup our answer is right. 
Woops, new to this. As I was trying to say, it is actually really simple if you try to figure it out. The answer is 42.

Which ordered pairs lie on the graph of the exponential function f(x)=4(5)^2x

select each correct answer:

(-1,4/25)

(0,0)

(1,4)

(2,2500)

Answers

The ordered pairs [tex]\left(-1, \frac{4}{25}\right)[/tex] and [tex](2,2500)[/tex] lie on the graph of the exponential function.

The quickest approach consists in evaluating the function at each value of [tex]x[/tex] to determine if the resulting value of [tex]y[/tex] coincide with the value given in statement.

x = -1

[tex]f(-1) = 4\cdot 5^{2\cdot (-1)}[/tex]

[tex]f(-1) = \frac{4}{25}[/tex]

The resulting value coincides with the value given in statement.

x = 0

[tex]f(0) = 4\cdot 5^{2\cdot (0)}[/tex]

[tex]f(0) = 4[/tex]

The resulting value does not coincide with the value given in statement.

x = 1

[tex]f(1) = 4\cdot 5^{2\cdot (1)}[/tex]

[tex]f(1) = 100[/tex]

The resulting value does not coincide with the value given in statement.

x = 2

[tex]f(2) = 4\cdot 5^{2\cdot (2)}[/tex]

[tex]f(2) = 2500[/tex]

The resulting value coincides with the value given in statement.

The ordered pairs (-1, 4/25) and (2, 2500) lie on the graph of the exponential function f(x) = 4 × (5)^(2x), while (0, 0) and (1, 4) do not.

To determine which ordered pairs lie on the graph of the exponential function f(x) = 4 × (5)^(2x), we can substitute the given x-values into the function and check if the resulting y-values match the given coordinates.

For the point (-1, 4/25):

f(-1) = 4 × (5)^(2(-1)) = 4 × 1/25 = 4/25

This matches the given coordinate, so (-1, 4/25) is on the graph.

For the point (0, 0):

f(0) = 4 × (5)^(2 × 0) = 4 × 1 = 4

This doesn't match the given coordinate, so (0, 0) is not on the graph.

For the point (1, 4):

f(1) = 4 × (5)^(2 × 1) = 4 × 25 = 100

This doesn't match the given coordinate, so (1, 4) is not on the graph.

For the point (2, 2500):

f(2) = 4 × (5)^(2 × 2) = 4 × 625 = 2500

This matches the given coordinate, so (2, 2500) is on the graph.
