Answer:
112 chocolate bars
Step-by-step explanation:
Given that the chocolatier made 16 batches of salted caramel chocolate bars, each batch consisted of 42 bars and he sent an equal number of bars to each of its 6 stores,
What is asked: To determine how many bars did each store receive.
Method of solving: Using elementary operations as multiplication and division.
Start considering each batch as the following box:
So it suggests that to find the total number of chocolates produced is equal to the product
Before multiplying, now see that the chocolatier is equally dividing them to its 6 stores, which means that he will take this quantity and divide equally into 6 boxes.
Therefore, this process is the same as dividing by 6, therefore
Is the expression that gives the result desired.
Simplifying the fraction and multiplying the terms gives
112 chocolate barsThis is the amount of chocolate bars each store received.
The histogram shows the ages of all the workers in a London office. Given that 27 people are in the 40-55 age range, work out the total number of people in the office.
Using the same method, determine the histogram's total area: divide it into rectangles and use the calculation for a rectangle's area to arrive at a total area of 100.The answer 40.
Determine the histogram's total area:
The area below the 40 to 55 line in the histogram must first be located.By using the area of a rectangle, one can determine the area: side side.
This will reveal a 60-square-foot space.
Then, using the same method, determine the histogram's total area: divide it into rectangles and use the calculation for a rectangle's area to arrive at a total area of 100.
You must now apply the rule of three:
The number of people between the ages of 40 and 55 is 25, and that age range corresponds to 60, as indicated by the question's sentence, so:
60 ———- 24
100 ———- x
60•x = 24•100
60x = 2400
x = 2400/60

Can you help me decribe how the placement of the decimal point change when you multiply a number I am a power of 10. How i thi the ame and different for diviion?
Multiplication: Decimal point moves right for every 10^n.
Division: Decimal point moves left for every 10^n.
When you multiply a number by a power of 10, the placement of the decimal point shifts to the right by the number of zeroes in the power of 10. For example, if you multiply 2.34 by 100 (102), the result would be 234.0, with the decimal point shifting two places to the right.

If ∠1 and ∠2 form a linear pair and m∠1 is eighteen less than twice m∠2, find the difference in the measures of the two angles.
Difference in the measures of two angles is 48°.
What are Linear Pair of Angles?Linear pair of angles are the pair of angles formed when two lines are intersected at a point.
Sum of the measures of angles of linear pair is supplementary or 180°.
Given that ∠1 and ∠2 form a linear pair.
m∠1 + m∠2 = 180°
Also, m∠1 is eighteen less than twice m∠2.
m∠1 = (2 × m∠2) - 18
Substituting second equation in first equation,
(2 × m∠2) - 18 + m∠2 = 180°
3 × m∠2 - 18 = 180
3 × m∠2 = 198
m∠2 = 198 / 3
m∠2 = 66°
m∠1 = (2 × 66) - 18 = 114°
Difference of the angles = m∠1 - m∠2 = 114° - 66° = 48°

After a certain number of people entered an empty room, 2/3 of the people who’d entered the room leave. After 2 more people leave, 1/4 of the original number of people who entered the room remain. What was the original number of people who entered the empty room?
Answer:
24
Step-by-step explanation:
Let x be the original number of people who entered the room
Since 2/3 of the people leave, 1/3 of the people remain = (1/3)x
If 2 more people leave, number of people remaining in the room = (1/3)x - 2
We know this to be 1/4 of the original number = (1/4)x
[tex]\rm{So\;\dfrac{1}{3}x - 2 = \dfrac{1}{4}x\\\\[/tex]
Multiply throughout by 12 to get rid of the denominator

Are parallel lines undefined or no solution?.
If the lines are parallel, then the pair of equations representing parallel lines have no solution.
Parallel lines are straight lines which, existing in the same plane and being produced indefinitely in both directions, do not meet one another in either direction. Another term involved is the "plane". We keep the Plane as an undefined term. The only thing is that we can represent it intuitively or explain it with the help of a physical model.
As the parallel lines never intersect at any point, hence the pair of equations of parallel lines will not have any solution, i.e. they have no solution.

Is Y =- 2x 5 in standard form?.
The equation y = -2x + 5 is already in the standard slope intercept form.
The slope-intercept form is a way of expressing the equation of a straight line in algebraic terms. The equation of a line in slope-intercept form is typically written as:
y = mx + b
Where m represents the slope of the line and b represents the y-intercept, which is the point at which the line crosses the y-axis. The slope-intercept form is useful because it allows you to quickly identify the slope and y-intercept of a line, given its equation. The slope represents the rate of change of y with respect to x, and the y-intercept represents the initial value of y when x is equal to 0. By using slope-intercept form we can easily graph the line and also can find the equation of the line from the graph.

Find the equation of the straight the line which passes through the point (3, 2) and cuts off equal intercepts on the axes.
Answer: The equation of a line can be written in the slope-intercept form y = mx + b, where m is the slope of the line and b is the y-intercept.
To find the equation of a line that passes through the point (3, 2) and cuts off equal intercepts on the x and y axes, we can use the following steps:
First, we need to find the slope of the line using the point (3, 2) and the fact that the line cuts off equal intercepts on the x and y axes. Since the line cuts off equal intercepts on the x and y axes, it means that it is a line of symmetry, which means that the slope of the line is zero.
Now we can use the point-slope form of a linear equation which is y-y1 = m(x-x1) and substitute the point (3,2) and the slope (0)
The equation of the line will be y = b where b is the y-intercept.
So the equation of the line which passes through the point (3, 2) and cuts off equal intercepts on the axes is y = 2
The line is a horizontal line passing through the point (3,2) and it cuts the x-axis at y = 2.

To solve the equation 6 - square root of x-2 = x + 4, you can follow these steps:
Start by isolating the square root term on one side of the equation. Subtract x + 4 from both sides to get:
6 - x - 4 - square root of x-2 = 0
Next, combine like terms:
2 - square root of x-2 = 0
Add square root of x-2 to both sides to get:
2 = square root of x-2
Now square both sides of the equation:
4 = x - 2
Finally, add 2 to both sides:
x = 6
So the solution is x = 6
