Answers

Answer 1
Answer:

Answer:  Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Length of a fence on a scale drawing = 6 cm

Scale = 1 cm : 4 m

Let the actual length of the fence be x

Since there is direct variation between the scale and actual.

According to ratio, we will have,

(1)/(4)=(6)/(x)\n\nx=6* 4\n\nx=24\ m

Hence, Option 'C' is correct.
Answer 2
Answer:  the answer is C if the scale is 1cm:4m 4x6 is 24

I have 1/3 of a brownie. If 5/6 of a brownie fills one plate, how many plates can I fill?

Answers


1/3 of a brownie is only 2/6.  If it takes 5/6 to fill one plate,
then your 2/6 can fill only 2/5 = 40% of one plate.
You can fill two playes because 1/3=2/6 and 2/6 goes into 5/6 twice with 1/6 left over.

How do you find the perimeter of a rectangle

Answers

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

Answer:

By adding up all the sides.

Step-by-step explanation:

An example of this is if you had a rectangle with the sides of 2, 5, 2, and 5 you would add all of those numbers up 2 + 5 + 2 + 5 = 14. The perimeter of the rectangle would be 14.
