S=51000(100-15)/100
s=51000(85/100)
s=51000(0.85)
s=$60000
3,000 ÷ 10 = 300
the way to check if it's correct is to multiply your answer and the number you divided 3,000 by.
The answer is 300
Answer:
0.5
Step-by-step explanation:
Remember what the equation states, mass divided by volume equals the density.
Divide -> 4/8
0.5
D=0.5
You have to sit calmly and quietly and look over this one for a few minutes,
until you see what's going on.
When the top triangle got flopped over to make the bottom one,
the 12-cm side on top made another 12-cm side on the bottom.
Also, the short 6-cm piece made another 6-cm piece hooked onto it,
and when those are put together, they make 12-cm all together.
So now, look at the whole outside triangle that you have, after the two
inside ones are put together. The top slanty side is 12-cm, the bottom
slanty side is 12-cm, and the straight up-and-down side is also 12-cm.
The new big triangle is an equilateral triangle !
What do you know about an equilateral triangle ?
-- All three sides are the same length.
-- All three angles are the same size.
If all three angles are the same size, how big is each one ?
Hint: The three angles of <em>every</em> triangle add up to 180 degrees.
So angle-y must be 1/3 of 180 = 60 degrees.

1) (x − 5)² = (x − 5) (x − 5) = x² − 5x − 5x + 25 = x² − 10x + 25 .
2) (x + 5)² = (x + 5) (x + 5) = x² + 5x + 5x + 25 = x² + 10x + 25 .
