A Blue Line train and a Yellow Line train just left the station at the same time. Blue Line trains run every 10 minutes, and Yellow Line trains run every 12 minutes. How long will it be until a Blue Line train and a Yellow Line train are at the station at the same time?
It takes 60 minutes (1 hour) for the Blue Line train and the Yellow Line train to be at the station at the same time, using their running time LCM.
How is the meeting time determined?The time that it will take the Blue Line train and the Yellow Line train to meet again at the station is determined using the Least Common Multiple or Factor.
The LCM is the smallest positive integer that is evenly divisible by both numbers, 10 and 12.
For instance, the LCM of 10 and 12 include 60 and 120 with 60 as the least.
Data and Calculations:The time the Blue Line runs is every 10 minutes.
The time the Yellow Line runs is every 12 minutes.
The LCM of 10 and 12 is 60 because 10 and 12 can divide 60 without a remainder.
Thus, it will take 60 minutes for the two trains to meet again at the station.

Arabella sells cars at a local dealership and gets paided by commission. she has already made $750 and will continue to earn $200 per car that's she sells. If her goal is to make $2750 by the end of the month, write + solve the equation below that models this months goal.
Answer:
$2,750 = $200x + $750
10 cars to meet the goal
Step-by-step explanation:
We will pull details we need to solve out of the question:
If her goal is to make 2,750 dollars, the money earned must equal at least $2,750.
If she's already made $750, then we can subtract that from what is needed left to make (or add it to what needs to be made).
Finally, she makes $200 per car. Let x equal the number of cars she sells.
Next, we will write an equation:
$2,750 = $200x + $750
Lastly, we will solve this equation.
$2,750 = $200x + $750
$2,000 = $200x
10 = x
She needs to sell 10 cars to meet her goal.
The sum of three consecutive integers is -51. Find the value of the greatest of the three.
Answer:
The value of the greatest of the three is -16
How to find the value of the greatest of the three?Let the smallest of the integers be x - 2
So, the other integers are x - 1 and x
The sum of the integers is given as
Sum = -51
So, we have the following equation
x - 2 + x - 1 + x = -51
Evaluate the like terms in the above equation
So, we have the following equation
3x = -48
Divide both sides of the equation by 3
So, we have the following equation
x = -16
Hence, the value of the greatest of the three is -16

Nicole and Daniel are splitting a pizza. Nicole eats 1/4 of the pizza and Daniel eats 2/3 of it. How much pizza is left? Write an equation to represent this situation.
Answer:
1 - 1/4 - 2/3 = r
Step-by-step explanation:
N=1/4, D=2/3
whole pizza=1
r=remainder pizza
1 - 1/4 - 2/3 =r
(1 - 1/4 - 2/3 =r)*12 ==> multiply by 12 to get rid of denominators
12 - 12/4 - 12*2/3=12r
12-3-24/3=12r
9-8=12r
12r=1
r=1/12 of a pizza left
Answer:
1/12
Step-by-step explanation:
the common number of 3 and 4 is 12. You multiply 1/4 by three and you get 3/12, and you multiply 2/3 by 4 and you get 8/12. You add 8 and 3 and you get 11, that's the number that indicates the part of the eaten pizza. 12-11=1. 1/12 left from the pizza.

A) 8
B) 9.4
C) 16.3
D) 36
Answer:
A
Step-by-step explanation:
∠ A and ∠ B are alternate exterior angles and are congruent , then
∠ B = ∠ A , that is
8x - 28 = 5x - 4 ( subtract 5x from both sides )
3x - 28 = - 4 ( add 28 to both sides )
3x = 24 ( divide both sides by 3 )
x = 8

Vertical Angle Theorem: two angles that are formed by two intersecting lines and are opposite each other are equal
The value of x is 23 because Angle FGI and Angle HGC are vertically opposite angles, the answer is 23.
What are vertically opposite angles?It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.
It is given that:
The triangle and two parallel lines are shown in the picture.
As we know, from the definition of the vertically opposite angle, two lines intersect each other at the intersecting point.
Angle FGI = Angle HGC = 14 degrees
4x = 78 + Angle HGC
4x = 78 + 14
4x = 92
x = 92/4
x = 23
Thus, the value of x is 23 because Angle FGI and Angle HGC are vertically opposite angles, the answer is 23.

Step-by-step explanation:
Define the variables:
Let the two numbers be x and y, where x > y.
Given information:
The larger of two numbers is one more than four times the smaller number.The sum of the number is 106.Create two equations from the given information and defined variables:
[tex]\begin{cases}x = 4y + 1\\x + y = 106\end{cases}[/tex]
Substitute Equation 1 into Equation 2 and solve for y:

[tex]\implies y=21[/tex]
Substitute the found value of y into the second equation and solve for x:
[tex]\implies x+21=106[/tex]

We are given different right angled triangles.
We need to find AB, CD and EF
We will do this by using the Pythagoras theorem.
Pythagoras theorem states that:
Hypotenuse² = Base² + Perpendicular²
For AB,
Hypotenuse = AB
Base = 2 units
Perpendicular = 4 units
So, we get that:
AB² = 2² + 4²
AB² = 4 + 16
AB² = 20
AB = √ 20
AB = 2√5 units
AB = 4.47 units.
For CD:
Hypotenuse = CD
Base = 2 units
Perpendicular = 2 units
So, we get that:
CD² = 2² + 2²
CD² = 4 + 4
CD² = 8
CD = √ 8
CD = 2√2
CD = 2.83 units
For EF:
Hypotenuse = EF
Base = 4 units
Perpendicular = 3 units
So, we get that:
EF² = 4² + 3²
EF² = 16 + 9
EF² = 25
EF = 5 units.
Therefore, we get that, the length of AB is 4.47 units, the length of CD is 2.83 units and the length of EF is 5 units.

You have 150 pieces of fabric to make a quilt. Each piece of fabric is a square with a side length of 4 inches. You use as many pieces of fabric as possible to create a square quilt.
The most pieces of fabric that can be used is 144 pieces, making a quilt with 12 pieces on each side.
What is a square?The square is a term to refer to a geometric figure that is characterized by being a type of parallelogram with four sides of equal length. A square is a regular polygon that has all its sides equal, and its interior angles measure 90º.
How to calculate what is the maximum number of pieces I can use to make a square quilt?To identify the number of square pieces that I can use to make a square quilt, I must keep in mind that to create a square quilt I must put the same number of pieces on each side of the quilt so that it forms a perfect square.
To identify the maximum number of pieces needed, we can try taking the square root of 150, 149, 148, 147... until the result is a integer number (no decimals). In this case the first integer that appears is 12 by taking the square root of 144 as shown below.
[tex]\sqrt[2]{144} = 12[/tex]
This means that to make a square quilt we must use 144 pieces in total and place 12 pieces on each side of the square. Additionally we can state that the side length of this quilt is 48 inches because each piece measured 4 inches on a side.
4 inches × 12 = 48 inches.
