Answer:
Polygon Y's area is one ninth (1/9) of Polygon X's area
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
In this problem
Let
z-----> the scale factor
a-----> Polygon Y's area
b----> Polygon X's area
we have
substitute
therefore
Polygon Y's area is one ninth (1/9) of Polygon X's area
The answer is that the assumed margin of error is 5%.
Here is how we calculate this;
<span>presidential approval rating is between 47% and 57%
</span>(57% - 47% ) / 2 = 10/2 = 5%
40% is the same as 40/100 so just multiply that with 60
60 x 40/100 = 24
thats how much is taken OFF so
60 is the original price and you get 40% discount off which is $24 on this specific item. how much is the price now?
Answer:
k = 5
Step-by-step explanation:
-2k = k - 7 - 8
Combine like terms
-2k = k - 15
add 15 to both sides
-2k + 15 = k
Add 2k to both sides
15 = 3k
Divide both sides by 3
k=5
Hope this helps!
