Equation that can find the value of the car on December 31, 2017 is:

A= 25000*(1-0.15)^7 and the value of car after 7 years is $8014.427.

Step-by-step explanation:

Price of car = $ 25,000

Rate of depreciation = 15 %

Formula used:

A= P(1-r)^n

where p= price of car

A= new price of car after depreciation

r = rate of depreciation i.e. 15/100 = 0.15

n= time in years 2017 - 2010 = 7 years

Putting values in formula:

A= 25000*(1-0.15)^7

A= 25000*(0.85)^7

A= $8014.427

So, Equation that can find the value of the car on December 31, 2017 is:

The length is 8.hope this helps.if it does

Please mark brainliest

Given a rectangle with a perimeter of 24 ft where the length is 4 ft longer than the width, we find that the length is 8 ft and the width is 4 ft by setting up and solving an equation based on the formula for the perimeter of a rectangle.

The subject of this question is about finding the length and width of a rectangle given the perimeter and a relationship between the length and width. The formula for the perimeter of a rectangle is 2 * (length + width). If a rectangle has a perimeter of 24 ft, and the length is 4 ft longer than the width, we can add the length and width together and multiply by 2 to calculate the perimeter.

Let's call the width 'w'. Then the length will be 'w + 4'. From the information given, we have:

Therefore, the width of the rectangle is 4 ft. This means that the length, which is 4 ft longer than the width, is 4 + 4 = 8 ft. So the length of the rectangle is 8 ft.

Answer:

7. 46.39 miles

8. 109 cm

9. 18 cm

Step-by-step explanation:

7. Look at the attached picture so you can picture the scenario.

The distance from City A to City B is 85 miles North. Notice that the plane only got to travel 20 miles North because of a cloudbank and redirected 108 degrees NORTH OF EAST, 20 miles towards that direction.

The new path makes a triangle, as shown in the picture.

The angle of the triangle was solved this way.

108° - 90° = 18°

The length of a was solved by getting how many miles the plane didn't travel in its original path.

85 miles - 20 miles = 65 miles.

So now we have our new given:

a = 65 miles

b = 20 miles  

c = ?

C = 18°

Using the cosine law we can solve for the c, which is the distance of the plane from City B.

[tex]c^{2}=a^{2}+b^{2}-2abCosC\\\\c^{2}=65^{2}+20^{2}-2(65)(20)Cos18\\\\c^{2}=4225+400-2600(Cos18)\\\\c^{2}=4625-2472.75\\\\\sqrt{c^{2}}=\sqrt{2152.25}\\\\c=46.39miles[/tex]

8. Again look at the attached. So as you can see we make another triangle. We can solve this with the cosine law once again. Just remember that the longer diagonal is opposite the biggest angle.

Given that:

a = 54cm

b = 78 cm

C = 110°

[tex]c^{2}=a^{2}+b^{2}-2abCosC\\\\c^{2}=54^{2}+78^{2}-2(54)(78)Cos110\\\\c^{2}=2916+6084-8424(Cos110)\\\\c^{2}=9000-(-2281.18)\\\\\sqrt{c^{2}}=\sqrt{11881.18}\\\\c=109cm[/tex]

9. Again, the shorter diagonal is facing the smaller angle. But we use the same cosine law to find it, but we use the formula of a, since a is what we are missing.

Given that:

a=?

A = 58°

b = 21cm

c= 15cm

[tex]a^{2}=b^{2}+c^{2}-2bc(CosA)\\\\a^{2}=21^{2}+15^{2}-2(21)(15)(Cos58)\\\\a^{2}=441+225-630(Cos58)\\\\a^{2}=666-333.85\\\\\sqrt{a^{2}}=\sqrt{332.15}\\\\a = 18cm[/tex]

Answer:

n = 28

Step-by-step explanation:

3/4n - 18 = 1/4n - 4 (eliminate fractions by multiplying each value by 4)

(3/4n * 4) - (18 * 4) = (1/4n * 4) - (4 * 4)

3n - 72 = 1n - 16 (move values with variable to same side)

3n - 1n - 72 = 1n - 1n -16

2n - 72 = -16 (move numeric values to same side)

2n - 72 + 72 = -16 + 72

2n = 56  (isolate n by dividing out the 2)

2n/2 = 56/2

n = 28

Answer:

x=9

Step-by-step explanation:

We have been given the following proportion;

x/6 = 6/4

In order to solve for x, we simply make x the subject on the left hand side;

To do this we multiply both sides by 6,

(x/6)*6 = (6/4)*6

x = 36/4

x = 9

The value of x is thus 9

if you simplify the answer you get its x=9

Answer:

The correct answer option is 20.3.

Step-by-step explanation:

We are given a right angled triangle with one known angle and one known side length and we are to find the value of x.

To find the value of x, we will use the appropriate trigonometric ratio.

[tex] sin 5 2 = \frac { x } { 2 5 . 8 } [/tex]

[tex] x = sin 52 \times 2 5 . 8 [/tex]

x = 20.3

Answer:

Step-by-step explanation:

Use the sine:

[tex]sine=\dfrac{opposite}{hypotenuse}[/tex]

We have

[tex]opposite=x,\ hypotenuse=25.8,\ \sin52^o\approx0.788[/tex]

Substitute:

Answer:

346 square inches

Step-by-step explanation:

Let's say you have a piece of paper that measures 2.3 inches by 2 inches.the area is 4.6 square inches. The closest whole number is 5, so rounded to the nearest square inch is 5 square inches. Fractions equal to half or greater get rounded up to the next whole number. Fractions less than half get rounded down. SO that means that 346.49 should be rounded down to just 346 although it may be almost 50.

I think that 2/4 would be bigger because 2/4 is the same as 1/2 and 1/2 is bigger than 1/8. Imagine a pizza, if i have 1/2 of a whole pizza i would have more pizza than a friend who had 1/8 of the whole pizza.

I hope this helps :)

If you simplify 2/4, you will get 1/2. 1/2 is bigger than 1/8.

Proof:

Draw 2 mental circles in your head. then draw lines that will make the circles out of 2 and out of 8. Now color in 1/2 of the first circle and 1/8 of the second circle. You can see that the 1/2 is bigger than the 1/8.

Hope I helped, sorry if I'm wrong ouo.

Simplif 1/2t to t/2

t/2 + 8 = 5/2t - 10

Simplify 5/2t to 5t/2

t/2 + 8 = 5t/2 - 10

Multiply both sides by 2

t + 16 = 5t - 20

Subtract t from both sides

16 = 5t - 20 - t

Simplify 5t - 20 - t to 4t - 20

16 = 4t - 20

Add 20 to both sides

16 + 20 = 4t

Simplify 16 + 20 to 36

36 = 4t

Divide both sides by 4

36/4 = t

Simplify 36/4 to 9

9 = t

Switch sides

t = 9

Answer:

t = 9.

Step-by-step explanation:

1/2 t + 8 = 5/2 t - 10

         - 8      -5/2 t

1/2 t - 5/2 t   =   -10 - 8

-2t = -18

t = 9.

6 inches separate the cities on the map

Explanation

We know that our scale factor is 1/4 inch = 1 mile, so we can create a conversion factor to convert 24 miles to inches. Since we need to convert from miles to inches, the denominator of our conversion factor must be 1 mile so we can cancel miles out. Notice that we can also express 1/4 inch as 0.25 inch to simplify our calculations:

We can conclude that if the conversion factor is 1/4 inch = 1 mile, 6 inches separate the cities on the map.
