Answer:
Spinner: 50%
Die: 50%
Step-by-step explanation:
Well for the spinner it depends on the amount of numbers it has,
in this case we’ll use 6.
So The probability of landing on the even numbers in a 6 numbered spinner.
2, 4, 6
3/6
50%
Your average die has 6 sides so the odd numbers are,
1, 3, 5
3/6
50%
Answer:
56-7m
Step-by-step explanation:
l7m–56l m<8
so lets replace m with something smalller then 8, how about 7
so then it would be...
l 7 * 7 - 56 l=
l 49-56 l = l -7 l
but the absulute value of -7 is 7, so how does this help us? well lets see
56-49= 7 this proves that all we have to do is switch the order giving us the solution 56-7m
hope this helped :)
108 miles 3 hours = 36 mph upstream
108 miles 2 hours = 54 mph downstream
bv = boat velocity in still water
cv = current velocity
bv -cv = 36
bv +cv = 54 Adding both equations
2*bv = 90
boat velocity in still water = 45 mph
since bv + cv = 54
then we know the current velocity = 9 mph
