I strongly believe your answer is correct
let a be aluminum and g be gold and k how many times:
2*10⁻¹mg a+ 6*10¹mg g= 154 lb
so a=kg
k=a/g
k=2*10⁻¹/6*10=1/300
a=1/300g
so Aluminum is 1/300 of gold.
In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.
Examples of line segments include the sides of a triangle or square.
More generally, when both of the segment's end points are vertices of a polygon or polyhedron, the line segment is either an edge (of that polygon or polyhedron) if they are adjacent vertices, or otherwise a diagonal. When the end points both lie on a curve such as a circle, a line segment is called a chord (of that curve).
So I think it would be 2
Answer:
NOT PROPORTIONAL
Step-by-step explanation:
The given two fractions are: 
and 
.
Proportional fractions are those which have the same value when to reduced to the simplest form.
Consider two fractions 
and 
.
We say they are proportional if 
.
Or, if 
then we can say the fractions are proportional.
Here the fractions are: and .
LHS: 5 X 10 = 50.
RHS: 8 X 8 = 64.
Clearly they are not equal. So, we can say these two fractions are not proportional.
Answer: 1/10
Step-by-step explanation:
1: Let’s take out the “DO NOT REPLACE IT.” It can make the whole thing seem harder. Rather, here is this. “There are five marbles in a bag, 3/5 are green and 2/5 are yellow. You DRAW TWO MARBLES. What is the chance of you drawing two yellow marbles?”
2 : Now let’s look at some important information.
100% of marbles= 5 marbles.
60% of marbles= the three green marbles.
40% of marbles= the two yellow ones.
Picking 2 of the 5 marbles will mean taking 40% of the marbles out of the bag.
Simplify: Now, to make it easier, the question is this. what is the chances of the 40% being the same color, Specifically yellow.
3: Let me explain. There are two yellow marbles, you pick out two. That is a one out of five chance of you getting ONE yellow marble the first time. That is 1/5. picking two at the same time results in a 2/5 chance.
4: if you pick twice it would be 1/10 chance.
