Since the intersection is - by definition - common to both sets, we can work out the number of people that use only the fitness suite or the swimming pool.
We know that 57 people use the fitness suite, but 36 of those are already counted in the intersection. So, 57-36=21 people use only the fitness suite.
The same goes for the swimming pool: 49-36=13 people use only the swimming pool.
So, we have:
- 21 people using fitness suite only
- 13 people using swimmng pool only
- 36 people using both
This sums to 21+13+36=70 people. We deduce that 30 people don't use any of the features.
Answer:
1/3
Step-by-step explanation:
We can find the slope using the slope formula
m = (y2-y1)/(x2-x1)
= ( 8-7)/(9-6)
= 1/3
Answer:
s=33.3333
Step-by-step explanation:
200=5s -(100+2s)
200= 5s -100 -2
100= 3s
s= 33.333
Answer:
1/2 gallon=2 quarts plus 3 quarts so 5 quarts then 11/4 would be 11 quarts so 11+2+3=16 quarts
Step-by-step explanation:
If the 11/4 part is confusing you on how many quarts it actually is it simply means that for every 4 quarts you get a gallon and you have 11 quarts so you can also look at it as 2 3/4 gallons if that somehow clarifies it.
Annual interest ----- 7,5%
halfyear interest ---- x%
----------------------------------
x = 0,5 *7,5/1 = 3,75%
7,5% +3,5% = 11%
$1500 ---------- 100%
x ----------------- 11%
-----------------------------
X = 11*1500/100 = 165
so this mean that $165 is the simple interest what Kara owes on in a 1,5 year
