We know that the diameter of the wheel is 80cm. Thus we can find the circumference of the wheel by the equation C=2(pi)r or, knowing that the Diameter is 2r, C=D(pi).
Now, we know that the circumference of the wheel is 80(pi)cm.
If the wheel rotates 170 times, that means we multiply the circumference of the wheel by 170 to receive the answer.
80 x 170 x pi = about 42725.66cm
we then can divide our answer by 100 to convert to meters -->
(42725.66cm)(1m/100cm) = 427.2566 which we round to 427m
Hope this helped!
Answer: The probability is 0.64
Step-by-step explanation: There are 39 counters in a bag. 14 of them are red and the remaining 25 are blue. Every time a counter is taken from the bag at random, there are altogether 39 possibilities regardless of the color of the counter drawn.
Also if we want to pick a blue counter from the whole lot, there are 25 possible chances.
Therefore the probability of picking a blue counter is shown as follows;
P(Blue) = Number of required outcomes ÷ Number of total possible outcomes
P(Blue) = 25/39
P(Blue) = 0.64
Therefore, the probability of taking a blue counter is 0.64 (or 64%)
Answer:
Multiplicación de polinomios cumple la propiedad distributiva.
Esta ley acostumbra a enunciarse diciendo que los factores se pueden agrupar de cualquier manera. Asimismo, el producto de polinomios también cumplía la propiedad conmutativa.
Step-by-step explanation:
The answer is to your math problem is -33.2
I will assume monthly compound interest.
Then:
yearly interest: 12%
monthly interest = (3/12) %
invested money: C
Final money: 2C
n: number of months
Compund interest formula:
Final money = Invested money * (1 + 0.03/12)^n
2C = C * (1.0025)^n
2C/C = (1.0025)^n
2 = (1.0025)^n
n = log(2) / log (1.0025)
n = 277.6 months
Time = 278 months = 23.1 years
