Hello!
We must use a certain formula to find the circumference of anything circular.
The formula is:
C = 2 × pi × r
We know that pi = 3.14 approximately and the radius is 3 feet.
Substitute:
C = 2 × 3.14 × 3
C = 6.28 × 3
C = 18.84 ft
ANSWER:
The circumference of the circular rug is 18.84 ft. (Last option)
Answer:
Step-by-step explanation:
We would apply the formula for exponential decay which is expressed as
A = P(1 - r)^t
Where
A represents the value of the car after t years.
t represents the number of years.
P represents the initial value of the car.
r represents rate of decay.
From the information given,
A = $2700
P = $20300
n = 2004 - 1997 = 7 years
Therefore,
20300 = 2700(1 - r)^7
20300/2700 = (1 - r)^7
7.519 = (1 - r)^7
Taking log of both sides, it becomes
Log 7.519 = 7 log(1 - r)
0.876 = 7 log(1 - r)
Log (1 - r) = 0.876/7 = 0.125
Taking inverse log of both sides, it becomes
10^log1 - r = 10^0.125
1 - r = 1.33
r = 1.33 - 1 = 0.33
The expression would be
A = 20300(1 - 0.33)^t
A = 20300(0.67)^t
Therefore, in 2007,
t = 2007 - 1997 = 10 years
The value would be
A = 20300(0.67)^10
A = $370
Answer:
can you post a question that actually has the right graphics
Step-by-step explanation:
P(volleyball and baseball) = 4/200 x 100 = 2%
P(either volleyball or baseball) = P(volleyball ∪ baseball) = P(volleyball) + P(baseball) - P(volleyball and baseball) = 12% + 15% - 2% = 25%.
25% play either volleyball or baseball.
You need to figure the mph for each person.
Maren drove 60 mph. No calculating needed there.
S drove 120/3 or 40 mph
T drove 84/1.2 mph or 70 mph
C drove 75/1/5 or 50 mph
The fastest was? (highest number is 70 as in Tomas)
