Answer:

x = 31

Step-by-step explanation:

∠ A and ∠ B are vertical angles and are congruent, then

6x - 25 = 5x + 6 ( subtract 5x from both sides )

x - 25 = 6 ( add 25 to both sides )

x = 31

A signal light is green for 4 minutes, yellow for 10 seconds, and red for 3 minutes. If you drive up to this light, what is the

posledela

Answer:

0.56 is the required probability.

Step-by-step explanation:

Time for which signal shows green light = 4 minutes

Time for which signal shows yellow light = 10 seconds

Time for which signal shows red light = 3 minutes

To find:

Probability that the signal will show green light when you reach the destination = ?

Solution:

First of all, let us convert each time to same unit before doing any calculations.

Time for which signal shows green light = 4 minutes = 4 $\times$ 60 seconds = 240 seconds

Time for which signal shows yellow light = 10 seconds

Time for which signal shows red light = 3 minutes = 3 $\times$ 60 seconds = 180 seconds

Now, let us have a look at the formula for probability of an event E:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

Here, E is the event that green light is shown by the signal.

Number of favorable cases mean the time for which green light is shown and Total number of cases is the total time <em>(Time for which green light is shown + Time for which Yellow light is shown + Time for which red light is shown)</em>

So, the required probability is:

$P(E) = \dfrac{240}{240+10+180}\\\Rightarrow P(E) = \dfrac{240}{430}\\\Rightarrow \bold{P(E) \approx 0.56 }$

A taxi charges $1.75 plus a fee of $0.75 for each mile traveled.the total coast of a ride without a trip is $4.75 how many miles

Alisiya [41]

y = .75x + 1.75

4.75 = .75x + 1.75

4.75 - 1.75 = 3

3 = .75x

3/.75 = 4

The trip is 4 miles.

m = 4
