Mr. Pickle bought an iPod from his friend who claims that the iPod was worth $250.00
when he bought it. The iPod's value decreases exponentially at the same rate each
year, and one year later the iPod's value is $187.50. By what percentage is the iPod's
value depreciating each year?

Step-by-step explanation:

−4x+5−13x+39=180

Step 1: Simplify both sides of the equation.

−4x+5−13x+39=180

−4x+5+−13x+39=180

(−4x+−13x)+(5+39)=180(Combine Like Terms)

−17x+44=180

−17x+44=180

Step 2: Subtract 44 from both sides.

−17x+44−44=180−44

−17x=136

Step 3: Divide both sides by -17.−17x

−17

Answer:

Area = 113.01 m²

Step-by-step explanation:

From the picture attached,

Area of the quadrilateral ABCD = Area of triangle ABC+ Area of triangle ACD

Construction to be done → Draw a perpendicular from a point A to the opposite side CD

Area of Δ ABC = [tex]\frac{1}{2}(AB)(BC)[/tex]

                         = [tex]\frac{1}{2}(12)(10)[/tex]

                         = 60 m²

Area of triangle ACD = [tex]\frac{1}{2}(AE)(CD)[/tex]

From ΔAEC,

sin(29°) = [tex]\frac{AE}{AC}[/tex]

AC = [tex]\sqrt{(12)^2+(10)^2}[/tex] [By Pythagoras theorem]

AC = [tex]\sqrt{244}[/tex]

AC = 15.62 m

Therefore, AE = 15.62sin(29)

                        = 7.57 m

Area of ΔACD = [tex]\frac{1}{2}(7.57)(14)[/tex]

                        = 53.01 m²                                

Area of ABCD = 60 + 53.01

                        = 113.01 m²            

Answer:

You are given a right triangle. The sum of the two acute angles should add up to 90 degrees. Set up an equation using the expressions given and solve for x. Once you know the value of x plug it back into each expression to find the measure for each angle.

Step-by-step explanation:

Angle 1 + angle 2 = 90

solve for x = ____

Plug the value into each expression to find the measure of each angle.

Answer:

D

Step-by-step explanation:

(2x+6)+(5x+14)=90

7x+20=90

7x=70

x=10

(2x+6)=26°

(5x+14)=64°

Answer

Input= 5

Output= 120

Step-by-step explanation:

The input goes up by 1, so m=5

The output shows how many hours there are in that many days so blank=120

Answer

output for m is 5

Step-by-step explanation

- multiply the input by a number to get the output

- to get the number to multiply it by you can divide a given out put by the input

( 24/2) = 12

- notice patterns

Answer:

If you were solving the right triangle, it would be:

m∠A = 46°

m∠B = 44°

m∠C = 90°

AB = 32

BC ≈ 23

AC ≈ 24

Step-by-step explanation:

To solve this right triangle, you can use trigonometric ratios to solve for the sides. To find the angle measures:

m∠A = 46° (given)

m∠B = x

m∠C = 90° (given)

180 - (46 + 90) = x

180 - 136 = x

44 = x

m∠B = 44°

To find the side measures, you can use tangent, sine, cosine, and the Pythagorean Theorem.

Recall that:

tangent = opposite side/adjacent side

sine = opposite side/hypotenuse

cosine = adjacent side/hypotenuse

So:

sin46 = BC/32

BC = 32 (sin46)

BC ≈ 23

tan46 = BC/AC

AC = BC/tan46

AC = (23.01887361...) (tan46)

AC ≈ 24

The first important details are given at the start, where the beginning amount of snow is 12 inches. This is a positive number.

Then, the next sentences tell us that the snow melts at a pace of 2 inches for an x number of days.

This can be represented by -2x because the word "melts" indicates a negative value.

From this, the equation can be made :)

Answer:

1009

Step-by-step explanation:

0,25 x 2018 = 504,5

20,18 x 25 = 504,5

504,5 + 504,5 = 1009

Answer:

1,009

Step-by-step explanation:

[tex] \frac{25}{100} \times 2018 = 504.5[/tex]

[tex] \frac{2018}{100} \times 25 = 504.5[/tex]

[tex]504.5 + 504.5 = 1009[/tex]

Answer:

1. 4x + 10

2. 3x + 22

Answer:

7 hours

Step-by-step explanation:

We are given that

At sunset, the temperature=-5 degrees Fahrenheit

Each hour, temperature falling=2degrees Fahrenheit

We have to find time taken to reach the temperature -19° F.

Let x be the time time taken to reach the temperature -19° F

According to question

[tex]-5+x(-2)=-19[/tex]

Where we taking 2 negative because temperature decreases.

[tex]-5-2x=-19[/tex]

[tex]-5+19=2x[/tex]

[tex]14=2x[/tex]

[tex]x=\frac{14}{2}[/tex]

[tex]x=7[/tex]

Hence, it will take 7 hours for the  temperature to reach -19° F.
