Answer:
Sharon bought a necklace with 90% blue beads.
Step-by-step explanation:
We are given that Sharon's necklace has 80 beads. We are also given that of those 80 beads, 72 of them are blue.
Therefore, we can set up a ratio of blue beads to total beads in order to find out the relationship.

Then, using the fraction we receive as a result, we can convert this to a decimal.

After we complete this calculation, we can multiply our decimal by 100 in order to obtain the relationship in percentage form.

Of the 80 beads, 90% were blue beads.
I think 1/4 is a good answer?

Answer:
They are equalivalent. 4 is half of 4 which makes is equal to 1/2
Step-by-step explanation:
6,824 rounded to the nearest ten is 6,820.
That is because 6,824 is closer to 6,820 than it is to 6,830.
Graph it like you would a normal equation except if it's not "equal to" it's a dashed line instead of solid line. Then shade the appropriate area on the graph,
for example..
y > 2x +1
is graphed as a dashed line y = 2x +1 since it doesn't actually equal y.
y is greater than the line/equation so the area above is shaded where y is bigger
