A box of chocolates contains bars of milk chocolate and dark chocolate. The weight of each bar of milk chocolate and dark chocolate is 150 ounces and 100 ounces respectively. If the number of bars of dark chocolate is 12 more than the number of bars of milk chocolate, and the total weight of the chocolates in the box is 2950 ounces, find the number of bars of milk and dark chocolate.
Answers
Answer:
7 milk chocolate
19 dark chocolate
Step-by-step explanation:
It is 2950 ounces in total, and dark chocolate is 100 ounces per bar and milk chocolate is 150 ounces per bar. There are 12 more dark chocolate bars so I multiplied 12 by 100 and that was 1,200. Then I took 2,950-1200=1,750. From there I subtracted 150 and 100 till I got to 0.
Number of bars of milk chocolate: 17
Number of bars of dark chocolate: 29
Let's use algebraic equations to solve the problem. Let's denote the number of bars of milk chocolate as "x" and the number of bars of dark chocolate as "y."
1. Weight equation: The total weight of the chocolates in the box is 2950 ounces.
We can express this as an equation:
150x + 100y = 2950
2. Quantity equation: The number of bars of dark chocolate is 12 more than the number of bars of milk chocolate.
We can express this relationship as:
y = x + 12
Now, we have a system of two equations with two variables:
Equation 1 : 150x + 100y = 2950
Equation 2 : y = x + 12
To find the values of x and y, we can use substitution or elimination. Let's use substitution in this case.
From Equation 2, we can substitute the value of "y" in terms of "x" into Equation 1:
150x + 100(x + 12) = 2950
Now, we can solve for "x":
250x + 1200 = 2950
250x = 1750
x = 7
Now that we have the value of "x," we can find the value of "y" using Equation 2:
y = x + 12
y = 7 + 12
y = 19
So, the number of bars of milk chocolate (x) is 7, and the number of bars of dark chocolate (y) is 19.

4. Identify the graph of the solution set of 9 > 3 + 2x.
Answers
Answer:
A
Step-by-step explanation:
9 > 3 + 2x
6 > 2x
3 > x
or
x < 3
and that means 3 is NOT included (otherwise there must be a smaller or equal sign). hence A is the right answer.
The graph of the solution set [tex]9 > 3 + 2x[/tex] is represented by the inequality relation x < 3.
The correct answer is Option A.
Given data:
The inequality is represented as 9 > 3 + 2x
The solution set of the inequality 9 > 3 + 2x can be found by isolating x on one side of the inequality:
Subtract 3 from both sides: 9 - 3 > 2x
Simplify: 6 > 2x
Divide both sides by 2: 3 > x
So, the solution set is x < 3.
Graphically, this represents all the values of x that are to the left of (less than) 3 on the number line. It forms an open interval to the left of 3. The graph consists of all real numbers less than 3, not including 3 itself. In interval notation, this can be written as (-∞, 3).
Hence, the inequality is x < 3.

PLEASE HELP WITH PART B!!
can you also explain y and x, I dont understand part B >
Answers
A. I would suggest including all units in your answer. Both answers are correct but the unit is also important.
average rate of change:
($750 - $350) / (2014 - 2010) = $400 / (4 years) = $100 per year
initial value:
$350
B. Take 2010 to be year 0. Then for year x = 0, the fee is y = $350.
If the fee increases at a rate of $100 per year, this means that when x = 1, y = $350 + $100 = $450. So the graph of the function that models the dog-walking fee is a line that passes through the points (0, 350) and (1, 450), adn the slope of this line is
(450 - 350) / (1 - 0) = 100/1 = 100
which is the same as the average rate of change.
Using the point-slope formula for a line, the equation you want is then
y - 350 = 100 (x - 0)
y - 350 = 100x
y = 100x + 350

Answers
The perpendicular bisector of a line divides the line into two equal segments and is perpendicular to the line
The perpendicular distance of point P from the line l is equal to the distance of the lost point s from the line l and points P and s are on opposite sides of the line l
The point s can be marked by constructing the perpendicular to line l passing through P
The steps to construct a perpendicular line from a point to a line and mark point s are given as follows;
Place the compass at the point P, and draw an arc intersecting line l at two points, A and BPlace the compass at point A and draw an arc with a radius, r, larger than half the length of segment AB above and below line lPlace the compass point at point B, and with the same radius r draw arcs intersecting the the arcs drawn from point A above and below the lineMark the point of intersection of the two arcs above and below the line l as the points D and EJoin points D and E with the a line to form the line DE drawn with a straightedge and extend DE line such that it passes through point PMark the point of intersection of the line DE and line l as the point F on the line lPlace the compass at the point F, and with a radius FP, draw an arc to intersect the line DE on the other side of the line lMark the point of intersection of the line DE by the arc of radius FP as the point sThe constructed point s above is the required point and points P and s are located on opposite sides of the line l

whats 186,282 rounded to the nearest thousand ?
Answers
Answer: 186,000
Step-by-step explanation:
You round the 282 down so that it is an even thousand. <3
186,282 rounded to the nearest thousand is 186,000.
To round 186,282 to the nearest thousand, we look at the digit in the thousands place, which is '6'.
If the digit in the hundreds place is 5 or greater, we round up. If it is less than 5, we round down.
In this case, since the digit in the hundreds place is '8', which is greater than 5, we round up.
To round up, we increase the digit in the thousands place by 1 and replace all the digits to the right with zeros.
Therefore, rounding 186,282 to the nearest thousand gives us 187,000.
