Answer:
They are saying that they have this conference room mapped out on a poster board kinda like a road map. But if you put something that big on a board it wont fit. So they had to make it small enough to fit it. When they say that 1/2 on the board is equal to 12 feet in the real room, They are tell you the scale you have to go by. So then they give you 3 1/2 inches on the board. You would see how many 1/2 inches there are in 3 1/2, which is 7, and multiply 7 by 12. The answer would be 84 feet. So they are say that 3 1/2 inches on the poster board, represents 84 feet in the real room.

Step-by-step explanation:
The minimum/maximum value of the function y = a(x − 2)(x − 1) occurs at x = d, what is the value of d?
Answer:
[tex]d=\frac{3}{2}=1.5[/tex]
Step-by-step explanation:
We have the function:
[tex]y=a(x-2)(x-1)[/tex]
And we want to find x=d for which the minimum/maximum value will occur.
Notice that our function is a quadratic in factored form.
Remember that the minimum/maximum value always occurs at the vertex point.
And remember that the x-coordinate of the vertex is the axis of symmetry.
Since a quadratic is always symmetrical on both sides of its axis of symmetry, a quadratic’s axis of symmetry is the average of the two roots/zeros of the quadratic.
Therefore, the value x=d such that it produces the minimum/maximum value is the average of the two roots.
Our factors are (x-2) and (x-1).
Therefore, our roots/zeros are x=1, 2.
So, the average of them are:
[tex]d=\frac{1+2}{2}=3/2=1.5[/tex]
Therefore, regardless of the value of a, the minimum/maximum value will occur at x=d=1.5.
Alternative Method:
Of course, we can also expand to confirm our answer. So:
[tex]y=a(x^2-2x-x+2)\\y=a(x^2-3x+2)\\y=ax^2-3ax+2a[/tex]
The x-coordinate of the vertex is still going to be the place where the minimum/maximum is going to occur.
And the formula for the vertex is:
[tex]x=-\frac{b}{2a}[/tex]
So, we will substitute -3a for b and a for a. This yields:
[tex]x=-\frac{-3a}{2a}=\frac{3}{2}=1.5[/tex]
Confirming our answer.

Terri buys five and seven eighths ounces of chocolate chips. She uses four and four sixths ounces in a recipe. How many ounces of chocolate chips does she have left?
a one and ten forty eighths ounces
b one and three fourteenths ounces
c two and ten forty eighths ounces
d two and three fourteenths ounces
Answer:
(A) [tex]1\frac{10}{48}[/tex]
Step-by-step explanation:
To find how many chocolate chips are left, you have to subtract the amount used for the recipe from the original amount which is:
[tex]5\frac{7}{8} -4\frac{4}{6}[/tex]
To subtract the two mixed numbers, first you have to convert them to improper fractions which would make the expression:
[tex]\frac{47}{8}-\frac{28}{6}[/tex]
Then, in order to subtract the two improper fractions, since they have different denominators, you have to make them have the same denominator. The LCM (Least Common Multiple) of 8 and 6 is 24, so to subtract the two fractions, you need both of them to have a denominator of 24. That would make the expression:
[tex]\frac{141}{24}-\frac{112}{24}[/tex]
To subtract these two fractions, since they have the same denominators, you can subtract the numerators and keep the denominators. That would make the answer:
[tex]\frac{29}{24}[/tex] which is, as a mixed number, [tex]1\frac{5}{24}[/tex], which is [tex]1\frac{10}{48}[/tex].

The set of values {29, 43, 59} contain possible solutions for g option (B) {29, 43, 59} is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that:
The inequality is:
0.08g + 0.2 < 5
Plug g = 29
0.08(29) + 0.2 < 5
2.52 < 5 (True)
Plug g = 43
0.08(43) + 0.2 < 5
3.64 < 5 (True)
Plug g = 59
0.08(59) + 0.2 < 5
4.92 < 5 (True)
Thus, the set of values {29, 43, 59} contain possible solutions for g option (B) {29, 43, 59} is correct.

A measuring scoop holds 10 cm3 of flour. Brandon's bag of flour contains 90 scoops. How many cakes can Brandon bake with his flour if his recipe calls for 180 grams of flour per cake? 1 cm3 of flour weighs 0.6 grams.
The number of cakes that Brandon can bake with his flour given the recipe is 8.
How many cakes can he bake?The first step is to determine the total cm³ of flour that is the bag of flour: 10cm³ x 90 = 900 cm³
Now, convert the answer gotten above to grams:
900 / 0.6 = 1500
The last step is to divide 1500 by 180
1500 / 180 = 8 cakes

You may determine the slope of the line by determining the rise and the run using two of the line's points.
What is Slope of the line?A line's slope is the change in y coordinate in relation to the change in x coordinate. The net change in y-coordinate is denoted by y, while the net change in x-coordinate is denoted by x. Where "m" represents the slope of a line. As a result, tan represents the slope of a line. Calculate the difference in y-coordinates between these two points (rise). Determine the x-coordinate difference between these two points (run). Divide the y-coordinate difference by the x-coordinate difference (rise/run or slope). The slope of a line indicates its steepness. Slope is calculated mathematically as "rise over run" (change in y divided by change in x).Therefore,
You may determine the slope of the line by determining the rise and the run using two of the line's points. The rise and the run are terms used to describe changes in height between two points. Rise divided by Run gives you the slope. Run = rise + slope Rise + run = slope.

Which term best describes the graph of y = –2?
increasing
decreasing
constant
positive
Answer:
It would be constant.
Step-by-step explanation:
Since there is no x value, the line will have no slope and just be horizontal about y= -2.
If we draw the graph we will see that the function is a straight line parallel to the x-axis.
The graph y = -2 is best described as a constant function.
Option C is the correct answer.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
A function:
y = -2
To graph the function we will find the coordinates of the function y = -2.
For x = 0,
y = -2
For x = 1,
y = -2
For x = 2,
y = -2
For x = 3,
y = -2
We will see that for all x values the y value is -2.
If we draw the graph we will see that the function is a straight line parallel to x-axis.
Thus,
The graph y = -2 is best described as a constant function.
