fredd [130]

Answer:

5cm by 1.95cm

Step-by-step explanation:

Let the length of the rectangle be x

Let the width be y

Perimeter of a rectangle = 2x + 2y

If the initial perimeter of a rectangle is about 13.9 cm, then;

13.9 = 2x + 2y ..... 1

If when the width is double the perimeter is 17.8cm, then;

17.8 = 2x + 4y ..... 2

Subtract 1 from 2;

13.9 - 17.8 = 2y - 4y

- 3.9 = -2y

y = 3.9/2

y = 1.95 cm

Substitute y = 1.95 into 1 to get x;

From 1;

13.9 = 2x + 2y

13.9 = 2x + 2(1.95)

13.9 = 2x + 3.9

2x = 13.9-3.9

2x = 10

x = 5 cm

Hence the dimension of the smaller triangle is 5cm by 1.95cm

What is the circumference of area=64pi mi^2
azamat

Answer:

  16pi mi

Step-by-step explanation:

The smallest circumference for a given area is that of a circle with that area. The area is given by ...

  A = πr²

so we can find r as ...

  64π = πr²

  r = √64 = 8 . . . . miles

The circumference of this circle is ...

  C = 2πr = 2π·(8 mi) = 16π mi

The circumference of the area is at least 16π miles.

_____

If the shape is not constrained to a circle, the circumference can be anything you like.

Find x in each triangle.<br> PLZ HELP!!!
jonny [76]

Answer:

<u><em>x=3.4</em></u>

Step-by-step explanation:

Use the Pythagorean theorem:

a^2+b^2=c^2

a and b are the legs and c is the hypotenuse (x)*

Insert the values:

3^2+1.6^2=x^2

Simplify exponents

9+2.56=x^2

Simplify addition:

11.56=x^2

Find the square root:

\sqrt{11.56}=\sqrt{x^2}

3.4=x\\x=3.4

Finito.

*The hypotenuse is the side opposite the 90° angle and the longest side of a triangle, always.
