Answer:

Step-by-step explanation:

Let the exponential function for the given table is,

f(x) = a(b)ˣ

Here, f(x) = Price of the item after 'x' years

a = Initial price of the item

b = Growth factor

x = Duration(years) from year 1913

By exponential regression calculator,

Exponential function represented by the table will be,

f(x) = 7.822(1.034)ˣ

Now we have to calculate the price of the item in year 2025.

Difference in time = 2025 - 1913

= 112 years

Price of the item after 112 years,

f(112) = 7.822(1.034)¹¹²

= $330.840

You want to find the width, AB, of a river. You walk along the edge of the river 100 ft and mark point C. Then
you walk 22 ft further and mark point D. You turn 90° left and walk until your location, point A, and point C are
collinear. You mark point E at this location, as shown.

(a) Suppose DE = 42 ft. What can you conclude about the width of the river? Explain. Your explanation
should include the approximate width and how you got this answer.
(b) Can you conclude that △ and △ are similar? Why or why not?

Answers

Answer:

It would be triangle A'B'C' with points (2, -1); (0, -3); and (2, -3).

Step-by-step explanation:

If you were to translate triangle ABC down by two, then the y-value of each point would decrease by two. Hence, (2, 1) would become (2, -1); (0, -1) would become (0, -3); and (2, -1) would become (2, -3).

Terry goes to the store to buy a shirt. The original price is $32. The shirt is
marked down 20%. When he gets to the check-out stand, he learns that
everything in the store is another 10% off of the marked down price. Which
dollar amount below is closest to the amount Terry paid for the shirt?

Answers

Answer:

The closest amount paid is $23

Step-by-step explanation:

Given

[tex]Price = \$32[/tex]

[tex]Mark\ down = 20\%[/tex]

Amount = 10% of Marked down price

Required

Determine the amount paid

First, we calculate the marked down price P2:

[tex]P_2 = Price(1 - Mark\ down)[/tex]

Substitute values for Price and Mark down

[tex]P_2 = \$32 * (1 - 20\%)[/tex]

Express percentage as decimal

[tex]P_2 = \$32 * (1 - 0.20)[/tex]

[tex]P_2 = \$32 * (0.80)[/tex]

Remove bracket

[tex]P_2 = \$32 * 0.80[/tex]

[tex]P_2 = \$25.6[/tex]

The payable amount is 10% off the marked down price,

This is calculated as:

[tex]Amount = P_2 - P_2 * 10\%[/tex]

Substitute $25.6 for P2

[tex]Amount = \$25.6 - \$25.6* 10\%[/tex]

Express percentage as decimal

[tex]Amount = \$25.6 - \$25.6* 0.10[/tex]

[tex]Amount = \$25.6 - \$2.56[/tex]

[tex]Amount = \$23.04[/tex]

The closest amount paid is $23

In a class with 28 students, there are 19 boys. What is the ratio of girls to boys? 9:19 19:28 19:9 28:9

Answers

Answer:

9:19

Step-by-step explanation:

Total number of students = 28

Number of boys = 19

Number of girls = Total number of students - Number of boys = 28-19 = 9

Therefore, ratio of girls to boys = Number of girls/Number of boys = 9/19 = 9:19

Answer: 9:19

Step-by-step explanation: The total number of students is 28.

Subtract the number of boys, 19

28 - 19 = 9 girls

Use those numbers for the ratio.

girls:boys

9:19

Net pay is the difference between a worker’s gross income and his or her deductions. A person’s gross income for the year was $65,000 and their total deductions were $12,860. What was their net pay for the year? Use the formula P = I - d, where P is the net pay, I is the gross income and d is the deductions.
a. $53,140 is the net pay
b. $77,860 is the net pay
c. $72,860 is the net pay
d. $52,140 is the net pay

Answers

We are given that I = $65,000 and d = $12,860. Using the formula, we get:

P = 65000 - 12860 = 52140

So, the person's net pay is $52,140, and the answer is D.

Hope this helps.

Gross pay is the amount of money your employees receive before any taxes and deductions are taken out. For example, when you tell an employee, “I’ll pay you $50,000 a year,” it means you will pay them $50,000 in gross wages.
Net pay is the amount of money your employees take home after all deductions have been taken out. This is the money they actually get on payday.
