Step-by-step explanation:
90/2 is proportional to 45
Answer:
k = 4/5
Step-by-step explanation:
First, rewrite 5/6k as (5/6)k; this is "five sixths of the variable k."
Next, identify the LCD. It is 6. Then the given equation becomes
5k + 4 = 8
Consolidate the constant terms:
5k = 4
Solve for k: k = 4/5
first you put 12 over 100 and that is 12/100 and then simplify
Answer:
55.5
Step-by-step explanation:
find the median - in this case it's 60
then group the upper and lower halves of the data:
(11, 19, 35, 42) 60 (72, 80, 85, 88)
now we find the medians of those sets:
35 + 19/2 = 54/2 =27
80 + 85/2 = 165/2 = 82.5
then subtract those two medians to find the interquartile:
82.5 - 27 = 55.5
Answer:
Step-by-step explanation:
1/9 of the camp means it has 9 parts the whole thing (each 1/9)
1/3 of an hour for 1 part and
for 9 parts we have
1/3 *9 = 9/3= 3 hours
