Look at this parallelogram. Find the value of c. c 17 m Perimeter=66 meters

sergiy2304 [10]

The value of c is 16.

Step-by-step explanation:

The perimeter of the parallelogram is given by,

Perimeter = 2( base + height )

The one of the dimension is given as 17 m.

Let us assume it has base of the parallelogram.

Therefore,

The base of the parallelogram = 17 m.
The perimeter of the parallelogram = 66 m.

Let, c be the height of the parallelogram.

To find the value of c :

Substitute the given data in the Perimeter of the parallelogram formula,

Put, height = c, base = 17 and perimeter = 66

⇒ Perimeter = 2 ( base + c )

⇒ 66 = 2 (17 + c)

Multiply 2 with each term inside the bracket,

⇒ 66 = 34 + 2c

⇒ 66 - 34 = 2c

⇒ 32 = 2c

Divide by 2 on both sides,

⇒ c = 32 ÷ 2

⇒ c = 16

Therefore, the value of c is 16.

Lucas bought a used car for x dollars. one year later the value of the car was 0.80 x. which expression is another way to descri

Mariana [72]

Knowing that a year later, the car is only worth 0.80 x, you can simplify that by stating that one year after purchase, the car is only worth 80% of its original purchase price.
Another way of stating that is that the car lost 20% of its value of the course of one year.

I am Lyosha [343]

Complete question :

Tim used the expression below, n³ where n represents side length, to determine the volume of a cube. Using this

expression, what is the volume of a cube with side length 3.5 inches? Show your work.

Answer:

42.875 cubic inches

Step-by-step explanation:

Given that :

The formula to obtain the volume of a cube is n³ ; where n = side length of the cube.

The side length of a certain cube is given as = 3.5 inches.

The volume of the cube is calculated thus :

Volume = n³ = 3.5³

Volume = (3.5 * 3.5 * 3.5) inch³

Volume = 42.875 in³

What is the value of f(4) + f(7)

tatyana61 [14]

Is there more to this problem? By saying f(4), you'd be inputting a 4 for every variable x. There is not enough info here to answer the question.
