The table shows the multiplication of two linear expressions. Select the correct reason for each step.
Reason 1:
Reason 2:
Reason 3:
Reason 4:
(A)associative property of multiplication
(B)commutative property of multiplication
(C)istributive property
(D) simplify
Answers
Reason 1: Distributive Property
The 1/4 x was distributed to each term in the parentheses.
Reason 2: Commutative Property
The individual factors were moved around to put numbers next to numbers and variables next to variables. (Technically the associative property was also used, to break down the previous parentheses, but I don't think your teacher is thinking about that.)
Reason 3: Associate Property
The similar factors were then regrouped.
Reason 4: Simplify
This is just simplifying.
Reason 1: Distributive property
Reason 2: Commutative property
Reason 3: Associative property
Reason 4: Simplify
What are the basic properties of Maths?What is the property of commutativity?
The rule governing the ordering of variables is the commutative property. It states that the order of the variables does not influence the final answer when they are added or multiplied.
What is the property of associativity?
The associative feature of real numbers relates to grouping variables. It states that altering the grouping of variables added to or multiplied by one another has no effect on the output.
In mathematics, what is a distributive property?
This property states that multiplying the sum of two or more addends by a number yields the same result as multiplying each addend separately by the number and then putting the resulting products together.
Detailed Explanation:First Argument: Distributive Property
[tex]\frac{1}{4x}[/tex]was allocated to each phrase between the parenthesis.
Reason 2: Property of Commutation
The individual elements were rearranged in order to place numbers alongside numbers and variables alongside variables. (Technically, the associative property was also utilized to separate the preceding parenthesis, although I doubt your teacher is aware of this.)
Reason 3: Associative Property
Similar elements were subsequently gathered.
Fourthly: simplify
This is just simplifying.
Reason 1: Distributive property
Reason 2: Commutative property
Reason 3: Associative property
Reason 4: Simplify

The roof of the building shown below has a span of 48 feet. The rafters upon which the roof is laid are 30 feet long, including a 4 foot overhung. a. Knowing that the pitch of a roof is the ratio of the rise to the run, find the pitch of this roof. B. If the entire roofline measures 100 feet from end to end, find the total area of the roof. c. Find the percent of the roof used for the overhang
Answers
Solution :
Given :
Span of the roof = 48 feet
Length of the rafter = 30 feet (including the 4 feet overhung)
So, for the 30 feet long rafter, 26 feet will be rafter length from the high point of the roof to the edge of the roof and 4 feet will be the roof overhung.
Therefore, the horizontal span per rafter is
[tex]$=\frac{48}{2}$[/tex]
= 24 feet
a). So the rise of the roof is [tex]$= \sqrt{(26)^2-(24)^2}$[/tex]
= 10 feet
b). Pinch of the roof is [tex]$=\frac{\text{rise}}{\text{run}}$[/tex]
[tex]$=\frac{10}{24}$[/tex]
[tex]$=\frac{5}{12}$[/tex]
c). The percent of the roof used as overhung is
[tex]$=\frac{4+4}{60}\times 100$[/tex]
[tex]$=\frac{80}{6}$[/tex]
= 13.33 %

Answers
Answer:
56 will be sick after 4 weeks.
Step-by-step explanation:
900 / 2 = 450 (Week 1)
450 / 2 = 225 (Week 2)
225 / 2 = 112.5 (Week 3)
112.5 / 2 = 56.25 (Week 4)

Gary's parents want him to attend The University of Houston. They opened a college savings account 15 years ago. Today, average yearly tuition and fees for one year at the university are about $10,350. Based on this information, about how much should Gary's parents have saved each of the 15 years to cover the cost of 4 years at The University of Houston?
Answers
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Today, average yearly tuition and fees for one year at the university are about $10,350.
I will assume a yearly interest rate of 8%.
First, we need to calculate the total amount needed:
Future value (FV)= 10,350*4= $41,400
Now, using the following formula, the annual deposit required:
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (41,400*0.08) / [(1.08^15) - 1]
A= $7,194.22
