We have:
c - the total number of cars,
d - the number of days;
c = f ( d ) = 100 d
Answer: C )
Answer:
n=-1
Step-by-step explanation:
-13+n+5+6=5+4n-4
n-2=4n+1
-2=3n+1
-3=3n
-1=n
Answer:
5' 6" = 66 inches
6 feet = 72 inches
shadow to actual height ratio = 72 / 66 = 1.0909...
If the tree casts a 20 foot shadow then its height equals
20 / 1.09090909 = 18.33 feet = 18 feet 4 inches
Step-by-step explanation:
Answer:
<em>No, I believe not</em>
Step-by-step explanation:
If these fractions were to form a proportion among one another, it would be that 13 / 14 should simplify to 1 / 2, but;
13 / 14 ( simplified ) ⇒ 13 / 14
Now there is another way to check if these fractions do form a proportion, by forming the proportion itself, applying cross multiplication to identify if either side is equivalent to one another;
13 / 14 = 1 / 2,
13 * 2 = 14 * 1,
26 ≠ 14,
<em>Answer; Thus these ratios really don't form a proportion among one another</em>
