Given:
a. 
b. 
To find:
The correct order for each set of cards from least to greatest.
Solution:
a.
Convert all numbers in decimal form.
It is clear that,
Therefore, the required order is 
.
b.
Convert all numbers in decimal form.
already in decimal form.
It is clear that,
Therefore, the required order is 
.
Need to see the questions to be able to answer
D must be perpendicular to a because d is parallel to c. c is perpendicular to b. b is parallel to a.
Remark
The easiest way to do this is to set up a proportion. But be careful how you do it.
Call the distance d
1/2 d / 3/5 hour = x * d / 1 hour
Divide both sides by d
1/2 // 3/5 = x / 1 Cross multiply
1/2 * 1 = 3/5 x divide by 3/5
Invert the bottom fraction and multiply.
The answer is 5/6 of the distance will be covered in 1 hour.
Answer:
f(n) = 8 - 3f(n-1)
d : { 8 >= x }
Step-by-step explanation:
Basically we know 8 is the first term, so we subtract 3 to get 5 which is the second term. Then we know d = -3. Now we that we established the formula, let's make a domain. We know x can never be greater than 8 so x is always less than or equal to 8.
