Emily wants to make a scale drawing of her kitchen. Her kitchen is a rectangle with a length of 6m and a width of 2m. She decides on a scale of 1cm to 0.5m. If the kitchen door is 1.2m wide, how wide should the door be on the scale drawing? Be sure to include units
Answer:
2.4 cm
Step-by-step explanation:
The scaled dimension on the drawing [tex]=[/tex] (Scale-factor) [tex]\times[/tex] (Original dimension)
She decides to draw 1cm for the original length of 0.5m=50 cm.
For this, the scaled dimension on the drawing=1cm and
the original dimention=50 cm
So, the scale-factor = 1/50.
As the kitchen door is 1.2m wide, i.e the original width of the door is 120 cm.
So, the scaled width of the door is
[tex]120\times \frac{1}{50}=2.4 cm.[/tex]
Hence, on the drawing, the width of the kitchen door should be 2.4 cm.

the Determine slope of ( 5 , 6 ) and ( 3 , 9 )
A. m = 3/2
B. m = -3/2
C. m= 6
D. m= 1/6
Answer
B
explanation
get the difference between the y valuesand divide it by the difference between the x values
[tex] \frac{9 - 6}{3 - 5} [/tex]
[tex] \frac{3}{ - 2} [/tex]
The slope of the line passing through the points (5, 6) and (3, 9) is -3/2.
Option B is the correct answer.
We have,
To determine the slope between two points, we can use the formula:
m = (y2 - y1) / (x2 - x1)
Given the points (5, 6) and (3, 9), we can substitute the coordinates into the formula:
m = (9 - 6) / (3 - 5)
m = 3 / (-2)
m = -3/2
Therefore,
The slope of the line passing through the points (5, 6) and (3, 9) is -3/2.

Choose the equation for the graph
Answer: a) Y= 2|x-3|+1
Step-by-step explanation:
Hope this helps
The equation that describes the graph is the one in option a:
f(x) = 2*|x - 3| + 1
Which equation represents the graph?We can see that the graph is an absolute value equation with a vertex in the point (3, 1), so the absolute value function must be of the form:
f(x) = a*|x - 3| + 1
Now, we also can see that the arms open upwards, so the slope must be positive, and we can see that for each increment in x, we have an increment of 2 units in y, so the slope is a = 2.
This means that the function is:
f(x) = 2*|x - 3| + 1
So the correct option is a.

Step-by-step explanation:
27-30: The factor pairs can be found by looking at the unique subsets of the set of prime factors. The product of the elements of each subset will be a divisor. The "empty" set can be considered to contain 1. When divisors are listed in numerical order, the factor pairs can be found by pairing factors from each end of the list, working toward the center. If the number is a perfect square, there will be an odd number of divisors, and the center number will be used twice
Examples:
18 = 2×3×3 (prime factorization).
Subsets of these factors are {}, {3}, {3}, {3,3}, {2}, {2,3}, {2,3}, {2,3,3}. Then the divisors are 1, 2, 3, 6, 9, 18. The factor pairs are 1×18, 2×9, 3×6.
25 = 5×5 (prime factorization).
Unique subsets are {}, {5}, {5,5}. Divisors are 1, 5, 25. Factor pairs are 1×25, 5×5.

The purpose of an exponent is to indicate repeated multiplication. That is, just as 2×3 means 2+2+2 (repeated addition), the use of an exponent means repeated multiplication: 2³ means 2×2×2.
This idea can be extended to give several rules of exponents--rules for multiplication, division, powers, and roots. All of these rules derive from the basic idea of repeated multiplication.
The number that is repeatedly multiplied is called the base. The exponent is called the power.
In plain text, the caret (^) symbol is used to signify an exponent. If an exponent is other than a single number or variable, it must be enclosed in parentheses, so that there is no confusion regarding what the exponent consists of. (This is an "order of operations" issue, since exponentiation must happen before any other operation.) In typeset math expressions, an exponent is rendered in superscript text.
31. -30^2 = -900 . . . base is 30, power is 2. The minus sign is not part of the base. Again, this interpretation is based on the "order of operations".
32. 12^4 = 20,736 . . . base is 12, power is 4.
33. 11^3 = 1,331 . . . base is 11, power is 3

Darnell uses 1 1/4 packages of bread to make 10 bracelets. He make 25 bracelets how packages of breads will he use
Answer:
3 1/8 packages of beads
Step-by-step explanation:
We know that Darnell uses 1 1/4 packages of beads to make 10 bracelets. In order to find how many packages of beads he'll need for 25 bracelets, we set up a proportion:
[tex]\frac{1\frac{1}{4} }{10} =\frac{x}{25}[/tex], where x is the number of packages needed
Cross-multiply:
25 * 1 1/4 = 10x
1 1/4 is just 1.25 in decimal form, so:
25 * 1.25 = 10x
31.25 = 10x
x = 3.125 = 3 1/8
So, Darnell will use 3 1/8 packages of beads.
~ an aesthetics lover
Answer:
We can calculate how many packages he needs to make 5 bracelets and then times that by 5 to see how many he'll need for 25
Step-by-step explanation:
First of all, let's turn 1 1/4 to [tex]\frac{5}{4}[/tex]
Now, if we divide the amount he needs for 10 bracelets by 2, we will have the amount he needs for 5 bracelets:
[tex]\frac{\frac{5}{4}}{2} = \frac{5}{4} * \frac{1}{2} = \frac{5}{8}[/tex]
Now, as 25 divided by 5 is 5, we can multiply our answer by 5 to get the amount needed for 25 bracelets:
[tex]\frac{5}{8} * 5 = \frac{25}{8}[/tex]
Now, we can turn this back into a mixed fraction:
[tex]\frac{25}{8} = 3\frac{1}{8}[/tex]
So the answer is 3 1/8 packages of bread.

The roots are there to confuse you. They have the exact same numbers under the radical, so you can treat it like a variable and add 4 + 3 since theyre like terms.

all functions are relations but why not all relations are functions
Answer:
All functions are relations, but not all relations are functions. A function is a relation that for each input, there is only one output. Here are mappings of functions. The domain is the input or the x-value, and the range is the output, or the y-value.
Answer:
Step-by-step explanation:
A relation between members of two sets X and Y is any set of ordered pairs {(x1,y1) (x2,y2) … }, finite or infinite in their number, provided the first member is from X and the second member is from Y. (Let’s not mention the uncountable possibility here).
E.g., if X = {Sunday, Monday, …, Saturday} and Y = {1,2, …, 31}, then the set {(Monday,1) (Tuesday,2) … (Monday,8) (Tuesday,9) … (Sunday,28)} is a useful relation for some February calendar, somewhere. It is “one-to-many”. And note that set Y need not be covered, but X must be. This distinguishes the domain of the relation (days of the week here) from its codomain (whole numbers 1 to 31 here).
Considering the vast set of all relations, there is one subset of great importance, those relations that have unique codomain values for each domain value. That is, each x in X is paired unambiguously with exactly one y in Y. These special relations are functions. The set of y in Y which have been paired with some x in X is called the range of f. Functions may still be “many-to-one”, as in y = r(x) which gives x rounded to the nearest integer. Thus r(2.3) = r(1.9) = 2.
Within the subset of functions are the one-to-one functions, which also have the property that every y in the range is paired with exactly one x in the domain. Because of this, these are the only functions that have an inverse function. Thus, the inverse function can be written as {(y1,x1) (y2,x2) … }. This shows that the domain and range of the original function are exactly exchanged in the inverse function.
E.g., y = tan(x) is one-to-one with domain [-pi/4 , pi/4] and range [-1,1]. Its inverse is x = arctan(y) with domain [-1,1] and range [-pi/4 , pi/4]. The roles of x and y are unambiguous, and shouldn’t be exchanged: x always in [-pi/4 , pi/4] and y always in [-1,1].

Given f(x) = -6(4 - x), what is the value of f(-0.6)?
A)-30
B) -27.6
C) -60
D) -24.6
Step-by-step explanation:
f(x) = -6(4-x) which f(-0.6)
therefore:
we multiple -6×4= -24 and -×- =+ this implies +6×x = 6x
we add:
-24 + 6x which we already know x is = -0.6
-24 + 6 (-0.6)
-24 + 3.6
= the big number always carry the sign
the answer is = -27.6

This means both rates are equal, since we got 20 for both of them

The absolute value function always gives a positive value, that is
| - a | = | a | = a
Given
| - 10 | + | - 20 |
= 10 + 20
= 30
Answer:
|-10| + |-20| = 30
Step-by-step explanation:
Absolute Value
The absolute value of x, written |x| is a positive number that represents the distance from the origin and the number.
In practice, the absolute value is found writing the number without the negative sign, if present.
For example:
|-9| = 9
|76| = 76
|0| = 0
The given expression is
|-10| + |-20|
Calculate each absolute value separately:
|-10|=10
|-20|=20
Thus:
|-10| + |-20| = 10+20 = 30
|-10| + |-20| = 30
