Answer:

0.7

Step-by-step explanation:

Let the number to be decreased be x. To decrease x by 30 %, the result will be

= x - 30% * x

= x - 0.3x

= 0.7x

From above, the result is 0.7 multiplied by the number to be reduced. Hence the multiplier is 0.7

What’s the circumference of this shape?xx

VikaD [51]

The hypotenuse of the triangle would be the diameter of the semi circle.

Using the Pythagorean theorem you can find that.

8^2 + 6^2 = x^2

64 +36 = x^2

100 = x^2

x = √100

x = 10

The diameter is 10, now find the circumference.

Circumference = diameter x PI = 10 x 3.14 = 31.4

Since it is a semi circle, the circumference would be 1/2 of that.

31.4 / 2 = 15.7

The perimeter would be 8 + 6 + 15.7 = 29.7
