Lan Is Preparing For His Trip To South Korea. He Has A Total Budget Of 2,192,896 Won For His Entire Trip. (2024)

Solution :

Given :

The height of the person is 5 foot.

The height of the lamppost is 12 foot.

Speed of the person away from the lamppost = 4 ft/s

Let the distance of the tip of the shadow of the perosn to the pole at t seconds after the person started walking away from the pole be d(t).

By similarity of the triangles, we see that

[tex]$\frac{12}{d}=\frac{5}{x}$[/tex] .................(i)

Here x is the distance from the person to the tip of the shadow. As it is given the speed of the person is 4 ft/s, then the distance of the person from the pole 4t. So we have,

x = d - 4t .............(ii)

Putting (ii) in (i) and solving for d is

d(t) = 6.85 t

So now if we derive d(t), we will get the wanted rate of the tip of the shadow.

∴ d'(t) = 6.85 ft/s

Answer:

Answer:

The answer is 60 hours.

Step-by-step explanation:

We could use proportions to solve.

[tex] \frac{1 \: hour \: on \: earth}{4hours \: on \: planet \: s} = \frac{x}{240hours \: on \: planet \: s} [/tex]

[tex]4 \times x = 4x \\ 1 \times 240 = 240[/tex]

[tex] \frac{4x}{4} = \frac{240}{4} \\ x = 60[/tex]

Answer:B

Step-by-step explanation:first subtract 2x from

3x+2=2x+4 Both sides .subtract 2 from

-2 -2 Both sides.after divide 1x from 1x

1x+2=4 To cancel 1.divide 2 and 1.then

-2 -2 You will get 2.

1x=2

1 1

X=2

Answer:

Step-by-step explanation:

Answer:

-2 and 3

Step-by-step explanation:

The x-intercepts or where the graph cuts the x-axis represents the zeros of y = x² - x - 6.

Thus, the zeros are -2 and 3. This is where the graph cuts the x-axis.

Therefore, the solutions of the graph are -2 and 3.

Answer:

$15.12

Step-by-step explanation:

1. Find the total amount of sales tax. This can be done by multiplying the before tax price by the sales tax percentage.

14 x 8% = 1.12

2. Add the sales tax amount back to the price.

14 + 1.12 = $15.12

Answer:

The answer would be 4.02% or simply 4%

Step-by-step explanation:

When you have a decimal like 0.0402 for example you move the decimal point to the right twice to get the percentage. Another example would be if you had the decimal 0.08 you would have the percentage 8%. Hope this helped!! If you have the time please mark brainlest?

Answer:

y=3sin(x)

Step-by-step explanation:

The best way to check if it's right is to use a graphing calculator. The negative trigonometric functions are going upwards from 1pi to 2pi and the positive ones are going downwards from 1pi to 2pi. Since the cos sign is shifted two units left, we can assure that 3sin(x) gives the most accurate answer.

Answer:

A. (2,4)

Step-by-step explanation:

use the substitution method.

for the second equation, subtract x on both sides to get y = 6-x

substitute that into the first equation

6 - x = 3x - 2

add x on both sides: 6 = 4x-2

add 2 on both sides: 4x = 8

divide by 4: x = 2

y = 6-2 = 4

Step-by-step explanation:

Step 1: Define systems

y = 3x - 2

x + y = 6

Step 2: Solve for x

Substitution

Substitute in y: x + 3x - 2 = 6Combine like terms: 4x - 2 = 6Add 2 to both sides: 4x = 8Divide 4 on both sides: x = 2

Step 3: Solve for y

Define original equation: x + y = 6Substitute in x: 2 + y = 6Subtract 2 on both sides: y = 4

Step 4: Graph systems

Step-by-step explanation:

Answer:

x = 1[tex]\frac{12}{17}[/tex], y = -2[tex]\frac{15}{17}[/tex]

Step-by-step explanation:

2x + 5y + 11 = 0 --- Equation 1

3x - y - 8 = 0

15x - 5y - 40 = 0 --- Equation 2

Equations 1+2: 2x + 5y + 11 + 15x - 5y - 40 = 0 + 0

17x - 29 = 0

17x = 29

x = 29 ÷ 17

x = 1[tex]\frac{12}{17}[/tex]

Substitute x = 1[tex]\frac{12}{17}[/tex] into Equation 1:

2x + 5y + 11 = 0

2(1[tex]\frac{12}{17}[/tex]) + 5y + 11 = 0

3[tex]\frac{7}{17}[/tex] + 5y = -11

5y = -11 - 3[tex]\frac{7}{17}[/tex]

= -14[tex]\frac{7}{17}[/tex]

y = -14[tex]\frac{7}{17}[/tex] ÷ 5

y = -2[tex]\frac{15}{17}[/tex]

Answer: x-intercept = (3,0); y-intercept = (0,7)

Step-by-step explanation:

-3y = 7x - 21

y = -7/3 x + 7 (divide both sides by -3)

y-intercept = (0,7) (y = mx + b; b is always y-intercept)

0= -7/3 x + 7 (plug in 0 for y to get x-intercept)

-7/3x = -7 (subtract 7 from both sides)

x = 3 (divide both sides by -7/3)

x-intercept = (3,0)

Answer:

(3)3 - 21/3 + 6 --> 9 - 27/3 --> -18/3

Answer:

If you take any number in the sequence then subtract it by the previous one, and the result is always the same or constant then it is an arithmetic sequence. The constant difference in all pairs of consecutive or successive numbers in a sequence is called the common difference, denoted by the letter d.

Step-by-step explanation:

Answer:

Amount = $14,024 (Approx)

Step-by-step explanation:

Given:

Amount received P = $13,500

Rate r = 7% = 0.07

Time t = 15 month = 15/12 = 1.25 = year

Discount rate = 6% = 0.06

Computation:

Maturity value = P[1+rt]

Maturity value = 13,500[1+(0.07)(1.25)]

Maturity value = $14,685.61

Time = 15 month - 6 month

Time = 9 month = 9/12 = 0.75 year

Amount = MV[1-dt]

Amount = 14,685.61[1-(0.75)(0.06)]

Amount = $14,024 (Approx)

Answer:

it's easy hope I could help

Step-by-step explanation:

the -3 goes on the y line

4/3 goes on the positive side so on the y and x

Answer:

If you know what the formula y = mx +b is, then you know that mx is the slope and b is the y-intercept.

Let`s suppose the equation is y = 2x + 1. The line should be intersecting with the coordinate (0, 1) on it`s way across.

The y axis will ALWAYS be the vertical line. Whatever coordinate the line crosses on the y-axis is the y-intercept.

The y-intercept can also be a negative number.
