rectangle with a perimeter of 1110 meters, this rectangular shape is 30 meters longer than 6 times its width. find its dimension

Alecsey [184]

Answer:

The width of the rectangle is 75 meters and length is 480 meters.

Step-by-step explanation:

The perimeter of the rectangle = 1110 meters

Let the width of the rectangle = k meters

So,the length of the rectangle = 6k + 30

Now, PERIMETER OF A RECTANGLE = 2(LENGTH + WIDTH)

⇒ 1110 = 2( k + (6k + 30))

or, 1110 = 14 k + 60

or, 14 k = 1110 - 60 = 1050

⇒ k = 1050/14 = 75

Hence, the width of the rectangle is k = 75 meters

and the Length of the rectangle is 6k + 30 = 6(75) +30

= 480 meters

Saige's spaceship traveled 588588588 kilometers (\text{km})(km)left parenthesis, start text, k, m, end text, right parenthesis i

Answer:

A is proportional

B and C are NOT proportional

Step-by-step explanation:

First, simplify 588 and 60:

588 divided by 6

60 divided by 6

= 98

Simplify them again by dividing them both by 2

= 49

Let's look at A:

441 and 45

Simplify by dividing by 9

= 49

It's pretty obvious that A is proportional because the simplified values are exactly the same.

Next, let's check B:

215 and 25

Simplify by dividing by 5

= 43

Now that its simplified you can compare

43 is smaller than 49

5 5

B is not proportional

Finally, let's check C:

649 and 110

Simplify by dividing by 11

= 51

Make 51 and 49 have the same denominator so we can compare them

10 5

51 can stay the same because 5 times 2 equals 10

49 times 2

5 times 2

= 98

Now that the denominators are the same we can compare

51 is much smaller than 98

10 10

Therefore, C is also not proportional.

Hope that helps :D
