Answer:
We will use the thales's theorem to solve for x
Let ? be x
then, the other segment on the same line as x will be 20 - x since the line is 20 units long
According to thales's theorem:
"If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points, the other two sides are divided in the same ratio"
Hence, we can write that,
9 / 3 = 20-x / x
3x = 20 - x
4x = 20
x = 5 units
Hence, the length of the line segment marked as '?' is 5 units
Answer is A... 0.25
2 1/2 = 2.5
2.5/10 = 0.25
hope it helps
B-I hole this helps like if I’m right
Answer:
The probability that Randy ride shares or drives his own car to work is 0.64
Step-by-step explanation:
Given;
- Randy wants to either ride share to work or drive his own car to work
- but it is impossible for Randy to ride share and drive his own car in one trip
let the probability that Randy ride shares be A
let the probability that Randy drives his own car be B
P(A) = 0.22
P(B) = 0.42
The probability that Randy ride shares or drives his own car to work;
P = P(A) + P(B)
P = 0.22 + 0.42
P = 0.64
Therefore, the probability that Randy ride shares or drives his own car to work is 0.64
