A car sells for $20,930. If the rate of depreciation is 6%, what is the value of the car after 8 years? Round to the nearest tho
Verizon [17]

Answer: 10,883.6

Step-by-step explanation: So first we have to find out what the depreciation is and to find that we have to take the 20,930 and times it by 0.06 (6%) which is 1,255.8,

So, we then times 1,255.8 by 8 because 8 years of depreciation, which is 10,046.4,

Finally we take 20,930 (the cars total value) and subtract the depreciation from it (10,046.4) so in 8 years the car is worth 10,883.6

A parking space shaped like a parallelogram has a base of 17 feet and a height of 9 feet if a mini car 6 feet long and five feet
lesantik [10]

Answer:

123 cm²

Step-by-step explanation:

First of all, we need to know how exactly to find the area of a parallelogram.

<u>Area</u><u> </u><u>of</u><u> </u><u>parallelogram</u><u>=</u><u> </u><u>Base</u><u>*</u><u>Height</u>

PARALLELOGRAM-

BASE= 17 ft

HEIGHT= 9ft

AREA= 17*9= 153 cm²

The area of parallelogram, will be considered as WHOLE AREA.

Now,

AREA OF MINI CAR-

length= 6 ft

Width= 5 ft

Area= 6*5= 30 ft ²

Square feet uncovere-

153 ft²- 30 ft²= 123 ft²

Can someone help me with this math homework please!
Anna71 [15]

Answer:

1.33 & n - 6 = 0.75(t - 8)

Explanation:

Speed can be calculated as miles ÷ minutes

4 ÷ 3 = 1.33 and 8 ÷ 6 = 1.33 as well

Since we know the n and t, we can substitute one into the equation to find the other (substitute t = 8 into all four equations and see do we get n = 6)

You can do this with t = 4 and n = 3 as well

C=-a/b what does a equal
Nutka1998 [239]

Answer:

a = -bc

Step-by-step explanation:

We are given the equation:

c = -a/b

Because multiplication and division are inverse operations, if we move b over to the other side, since it was dividing on the right side, it would be multiplied on the other side (I don't know how to explain that well)

so you can make it look like this:

b*c = -a

Or:

-a = b*c

Then, do isolate a, we will have to divide by -1 on both sides

a = -b*c

To check this, we can plug in numbers

-8 = -16/2

-16 = -8*2

16 = 8 * 2

Let me know if you have any questions
