Answer:
B 2 2/3
Step-by-step explanation:
Triangles ADB and CDB are similar. Therefore similar parts can form a proportion.
AD/DB = DB/DC
AD = ?
DB = 4
DC = 6
x/4 = 4/6 Cross multiply
6x = 16
6x/6 = 16/6
x = 2 4/6 or x = 2 2/3
It's B
12/2= 6 miles/hour
*(miles/hour) & (miles per hour) mean the same thing, by the way
Put the 12 miles in the numerator and the 2 hours in the denominator, divide the 2 hours by 2 (which will be 1) since we want to know the distance travelled in "one" hour. Then divide the 12 by 2 because what you do with the denominator must also be done with the numerator and vice versa.
The probability that Boris will win the contest is:
P = 0.286
<h3>
How to get the probability?</h3>
For some given odds a:b, the probability is just computed as the quotient between a and b, which gives:
P = a/b
In this case, the odds are 2:7, so the probability that Boris will win the contest is:
P = 2/7 = 0.286
Written in percentage form, we get:
P = 28.6%

-248.66 + x = 544.12
544.12 - (-248.66) = 792.78
-248.66 + 792.78 = 544.12
Answer:
S(10)=3*(1-(5/3)^10)/(1-5/3)
Step-by-step explanation:
It is Geometric series with r:
r=5/3=(25/3)/5=5/3
a=3
Sum of G.S. in formula:
S(n)=a(1-r^n)/(1-r)
S(10)=3*(1-(5/3)^10)/(1-5/3)
