Answer:
70.42 kilometers.
Step-by-step explanation:
43 minutes/60 minutes (1 hour is 60 minutes) = 0.71 hours.
Now we set up a problem here.
50 kilometers/0.71 hours = x kilometers/1 hour
We multiply out 1 hour and cancel out from both sides.
50/0.71 kilometers = 70.42 kilometers.
Therefore, the train was traveling at 70.42 kilometers per hour.

la suma de los primeros n enteros positivos es un numero de tres digitos iguales. cual es la suma de los digitos de n?
The sum of n natural numbers is three digits number and all digits are the same. The same digits is 6 and the sum is 666.
A three-digit number with the same digits is the sum of n natural numbers.
Let's say the sum of n natural numbers is bbb.
Then,
n( n + 1) / 2 = bbb
n( n + 1) / 2 = b( 111 )
n( n + 1) / 2 = b ( 3 × 37 )
n( n + 1) = 6b × 37
Now, the left-hand side of the equation is the product of two consecutive natural numbers.
Therefore, the right-hand side of the equation is also the product of two consecutive natural numbers.
Hence, 6b = 36
b = 36/ 6
b = 6 and n = 36
As a result, 36 numbers have been added together, and their total is 666.

slope -1/2, passes through (0, 5)
Our standard linear slope equation is:

We're told our slope is 1/2, so that's our m value.
When x = 0 our value is 5. If you need this visualized, then:
1/2 * 0 +b = 5
0 + b = 5
b = 5
So our equation looks like:

ZA and ZB are vertical angles. If mA = (5x +24)° and m/B= (6x - 5)°,
then find the measure of ZB.
The measure of ∠B = 189°
Here it is given that
∠A = (5x + 24)° and ∠B = (6x - 5)°
∠A and ∠B are vertical angles
Since vertical angles are always equal so
∠A = ∠B
5x + 24 = 6x - 5
add +5 on both sides, we get
5x + 24 + 5 = 6x - 5 + 5
5x + 29 = 6x
add -5x on both side, we get
5x - 5x + 29 = 6x - 5x
x = 29
Now put the value of x in 6x - 5
6 × 29 - 5 = 189
The measure of ∠B = 189°

A man drove 14 mi directly east from his home, made a left turn at an intersection, and then traveled 9 mi north to his place of work. if a road was made directly from his home to his place of work, what would its distance be to the nearest tenth of a mile?
If a road was made directly from his home to his place of work, its distance will be 16.6 mi.
If a man drives east from his home, makes a left turn at an intersection, and then travels north to his place of work, then the path he travels resembles the sides of a right triangle (see attached photo).
if a road was made directly from his home to his place of work, then this path will be the hypotenuse of the triangular path.
Using Pythagorean theorem, we can solve for the distance of the road.
c^2 = a^2 + b^2
where c is the distance of the road
a is the distance he travels to the east
b is the distance he travels up north
c^2 = a^2 + b^2
c^2 = (14 mi)^2 + (9 mi)^2
c^2 = (196 + 81) mi^2
c^2 = 277 mi^2
c = 16.64331698 mi
distance of the road = c = 16.64331698 mi
Rounding off to the nearest tenth of a mile:
distance of the road = 16.6 mi
