Think of how many there are. im not sure if you put these into ratios or not...
like for number 3 think of how many numbers 1-9 are multiples of three
1 2 3 4 5 6 7 8 9
and once you get that number you make it out of 9 because there were 9 numbers
Example
3:9 3/9
for questions one and two its out of 52 and if you don't know how many clubs and hearts are in a deck you can look it up and put it in a ratio with 52
Answer:
its hidden!!!!!!! :D thanks for points ;)
854 it’s the only one I can think of
Given that,
Speed of first bicycle = 9 mph
Speed of second bicycle = 5 mph
Suppose the length of the circle 24 miles.
We need to find the relative velocity
Using formula of relative velocity
Put the value into the formula
We need to calculate the time
Using formula of time
We need to calculate the distance of the points where the two bicycles meet
Using formula of distance
For first bicycles,
For second bicycles,
Hence, The points where the two bicycles meet after every 6hr at 30 miles and 54 miles.
Answer:
C.) 21
Step-by-step explanation:
d = 22.5n + 27.5
Where d is the total amount of money earned and n is the number of items sold
Substitute:
500 = 22.5n + 27.5
We can substitute 500 for d because 500 is the total amount of money Kathryn wants to earn
Solve:
500 = 22.5n + 27.5
Subtract 27.5 on both sides:
500 = 22.5n + 27.5
-27.5 -27.5
472.5 = 22.5n
Divide by 22.5 on both sides:
472.5 = 22.5n
/22.5 /22.5
21 = n
Therefore, Kathryn must sell 21 items to make $500.
