1. Stock Market:
If a stock price decreased $2 per day for four days, then the total change in value of the stock is $8. (2 x 4)
Answer: $8.
2. Evaporation:
With the given information, we can infer that if 3 inches of water in a tank decreases each week, then 15 inches of water would decrease over the course of 5 weeks. (3 x 5)
Answer: 15 inches.
3. Football:
If a football team lost 9 yards on 3 consecutive plays, then the team's total change in position is 27 yards. (9 x 3)
Answer: 27 yards.
Hope this helps! Good luck.
Answer:
B. 95º
Step-by-step explanation:
Supplementary angles are ones that add up to 180º.
So if angle 1 is 85º, then the equation would be:
(x-the measure of angle 2)
X + 85 = 180
Solve for x:
X + (85-85) = 180-85
X = 95.
Hope this helps! Have a great day!
Answer:
0.45 = 45% probability that the member uses the golf course but not the tennis courts
Step-by-step explanation:
I am going to solve this question using the events as Venn sets.
I am going to say that:
Event A: Uses the golf courses.
Event B: Uses the tennis courts.
5% use neither of these facilities.
This means that 
75% use the golf course, 50% use the tennis courts
This means, respectively, by:
Probability that a member uses both:
This is 
. We have that:
So
What is the probability that the member uses the golf course but not the tennis courts?
This is 
, which is given by:
So
0.45 = 45% probability that the member uses the golf course but not the tennis courts
Answer:
16 days
Step-by-step explanation:
Given that:
Number of paramecium Aurelia doubles every 1.25days
5 days ago ; number of paramecium Aurelia = 1
How many are there now?
Using the relation :
Multiplier^(total number of days / time it takes to multiply)
Multiplier = doubles = 2
Total number rof days =. 5
Time it takes to. Multiply = 1.25
The formula becomes :
Number(n) of ptotozoan in 5days is given by 2^(5/1.25)
n = 2^(5/1.25)
n = 2^4
n = 2 * 2 * 2 * 2 =. 16
