Answer: at 11:54
Step-by-step explanation:
Let's define the 10:30 as our t = 0 min.
We know that Train A stops every 12 mins, and Train B stops every 14 mins, they will stop at the same time in the least common multiple of 12 and 14.
To find the least common multiple of two numbers, we must do:
LCM(a,b) = a*b/GCD(a,b)
Where GCD(a, b) is the greatest common divisor of a and b.
In this case the only common divisior of 12 and 14 is 2.
So we have:
LCM(12, 14) = 12*14/2 = 84.
Then the both trains will stop 84 minutes after 10:30
one hour has 60 mins, so we can write 84 minutes as:
1 hour and 24 minutes = 1:24
Then they will stop at the same time at 10:30 + 1:24 = 11:54
If b is the midpoint of line AC, and AC = 8x-20, find BC.
The Definition Of a Midpoint says that is B is the
midpoint of segment AC, then segment AB ≅ AC.
Since segment AB ≅ segment BC, we can setup
the equation 2(3x - 1) = 8x - 20 and we can solve from here.
Start by distributing the 3 through the parenthses on the left side.
So we get 6x - 2 = 8x - 20.
Now subtract 8x from both sides to get -2x - 2 = -20.
Now add 2 to both sides and we have -2x = -18.
Finally, dividing both sides by -2, we find that x = 9.
If x = 9, segment BC must be 3(9) - 1 or 27 - 1 which is 26.

fish tacos?
Step-by-step explanation:
4x-2.50=14.30
14.30-2.50=11.80
11.80/4= $2.95
each taco is 2.95
check your answer
$2.95*4= $11.80

If a line contains the point (0,-1) and has a slope of 2 what point is on the line A.(2,1) B.(1,1) C.(0,1)
Answer: B. (1,1)
Step-by-step explanation: If you find slope with the points (0,-1) and (1,1) you will get a slope of 2.
the formula you can use is y2-y1/x2-x1
substitute the values with the 2 points i mentioned
1-(-1)=2
1-0=1
divide 2/1
and you get 2
So B, (1,1) would be your answer.

Describe a sequence of transformations that shows that Polygon A is congruent to Polygon B.
Answer:
The sequence of transformations that shows that Polygon A is congruent to Polygon B is given as follows;
1) A translation of 8 blocks to the right followed by 2) a translation of 2 blocks down and 3) a rotation of 90 degrees anticlockwise
Step-by-step explanation:
Given that the dimensions and shape of Polygon A and Polygon B are equal, the sequence of transformations that will show their congruency should include a number of rigid transformations, mainly translations and rotations.

When a snack bar opens, the cash register contains at least 50 dollars in $1 and $5 bills. Which of these inequalities represents this situation, where x is the number of $1 bills and y is the number of $5 bills?
Answer:x + 5y is greater than or equal too $50
Step-by-step explanation:
If x is equal to the amount of $1 then there is no need for a coefficient. Being that y is represented as $5 there needs to be a coefficient of because it’s five dollars times however many you have. Then it is greater than or equal to $50 because the problem states there is at least $50 in the register.

We have been given that the physical therapist earns $49,830 a year and is single with no dependents.
To determine the amount withheld from his biweekly pay for state income tax.
Since the state income tax rate is 5% of taxable income.
So the amount withheld from his biweekly pay for state income tax as:
⇒ 5 % of 49,830
⇒ (5/100)49,830
⇒ (0.05)49,830
⇒ 2491.50

ITS BEEN AN HOUR LS ILL GIVE BRAINLITST
Answer:
38.81%
Step-by-step explanation:
Circle area = п r ²
п = 3.14
r = 4 cm
Circle area = 3.14 * (4cm)²
Circle area = 3.14* 16cm²
Circle area = 50.24cm²
Triangle area = (heigth*width)/2
heigth = 2.5 + 4 = 6.5cm
width = 3 + 3 = 6cm
triangle area = (6.5cm*6cm)/2
triangle area = 39cm²/2
triangle area = 19.5cm²
then:
the probability that a randonly select point whitin the circle falls in the shaded area is:
19.5/50.24 = 0.3881 (aprox)
0.3881*100 = 38.81%
