1. A straight fence is constructed from posts 6 inches wide and separated by lengths of chain 5 feet long. A certain fence begins and ends with a post. If there are 7 posts, what is the total length of the fence?
Answers
Answer:
72
Step-by-step explanation:
First, we will multiply the number of posts (7) by the posts' width (6) to get 42.
Since there is a chain between each post, there are 6 chains.
Multiplying the number of chains (6) by the chains' length (5), we get 30.
The question asks us to find the total length of the fence, so we add 42 and 30 and get 72.

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answers
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day

What is the value of C in the table?
6
10
49
70
Answers
Answer:
The value of C in the table is 0. Total number of cake lovers = Total - (number of students who chose pie) = 138 - (36 + 42 + 60) = 138 - 138 = 0
Step-by-step explanation:
The value of C in the given table is 10. Therefore, option B is the correct answer.
What is proportionality?The property of having suitable proportions in terms of size, number, degree, harshness, etc.: If a defensive action against an unfair attack results in the destruction that contravenes the proportionality criterion, it may even go far beyond a justifiable defense.
From the given table,
42/7 = 60/C (Using proportionality)
6=60/C
C=10
Therefore, option B is the correct answer.

solve for r: q = p(r + s)
Answers
Answer:
\(r=\frac{q-ps}{p}\)
General Formulas and Concepts:
Order of Operations: BPEMDASEquality PropertiesDistributive PropertyStep-by-step explanation:
Step 1: Define equation
\(q=p(r+s)\)
Step 2: Solve for r
Distribute p: \(q=pr+ps\)Subtract ps on both sides: \(q-ps=pr\)Divide both sides by p: \(\frac{q-ps}{p} =r\)Rewrite: \(r=\frac{q-ps}{p}\)Step-by-step explanation: To solve for r, start by distributing the p
through the parentheses on the left side to get q = pr + ps.
Next, isolate the r term by subtracting ps from both sides to get -ps + q = pr.
Finally, to get r by itself, divide both sides by p and we have -ps + q/p = r.
QUICK! Find the area of the smallest square in the diagram.

B) 5 square feet
C) 313 square feet
D) 13 square feet
Answers
Answer:
313 square feet
Step-by-step explanation:
313 square feet
Answer:
A) 25
Step-by-step explanation:
sides of top square are all 13 and sides of bottom square are all 12
we now have the hypotenuse (13) and another side length of the triangle (12) using a^2+b^2=c^2 we can find the side of the square then its area.
144+b^2=169
b^2=25
b=5, which means the smallest square's sides are all 5 making it have an area of 25

Julia loves collecting baskets. Every month she adds two new baskets to her collection. In the month of March she has 60 baskets. She’s worried she will soon run out of room in her apartment to keep her baskets. Write an equation that represents the percent of change of her basket collection from the beginning of the year to the end of the year, then solve.
Answers
The linear function that represents the amount of baskets in the xth month of the year is given as follows:
The percentage of her collection that she needs to get rid of is of 3.85%.
Linear Function:-
The definition of a linear function is:
y = b + mx
In which the parameters of the equation are given as follows:
•b is the value of y when x=0
•m is the rate of change for each unit of x
Every month she adds 2 new baskets to her collection, hence the slope is of : m = 2
Then: y = b + 2x
From the March amount, when x = 3, y = 60, hence the intercept b is given as follows:
60 = b + 6
b = 54
Hence the equation is: y = 54 + 2x
At the end of the year (12 months) the amount of baskets that she will have is of:
y = 54 + 2 × 12 = 78
Hence, she has to get rid of 3 baskets, as 78 - 75 = 3, and the percentage is of:
p = 3/78 × 100% = 3.85%.
