(1/2) ^5 = 1/32 nd of the original will be left
1/32 * 200g = 6.25 gm left
Answer:
The circumference of a circle is equal to π , which is a number ≈3.14 , multiplied by the diameter of the circle. Therefore ... We also know that the diameter has twice the length of the radius. In equation form: 2r=d. 2r=16. r=8. Note that since 2r=d , the equation C=2πr holds and can be used in place of C=πd .

-4 + -10 = -14
Negative 4 plus negative 10 = negative 14 (thats what I think the answers gonna be, but im not that sure though)
Answer:
C.) Triangle TUV ~ Triangle WXY
Step-by-step explanation:
Find the angles that are equal in each triangle, and put them in the same position in the statement.
T and W are equal; therefore, they are first in each.
U and X are equal; therefore, they are second in each.
V and Y are equal; therfore, they are last in each.
