Ms. Francis is planning a birthday party for her daughter. There will be 22 children at the party, and in order to seat them all she needs to rent square card tables. Only 1 child can sit at each side of a card table.
Ms. Francis wants to arrange the tables in a rectangular shape so they look like one large table. The room is large enough that
the rectangle can be made with more than one row of tables.
Part A: How many different arrangements can Ms. Francis make to seat all 22 children?
Part B: What is the smallest number of tables that Ms. Francis needs to rent?
DIRECTIONS: To solve the problem, apply the steps of the Mathematical Problem-Solving Routine.
Understand

2. State the problem in your own words.

Answers to both the subparts are:
(A) Ms. Francis would have to rent 6 tables in order for everyone to have their own side.(B) She could have all of the children sitting at their tables, each with their own side, but the sixth table would only have two other children.What are mathematical operations?An operation is a function in mathematics that takes zero or more input values (also known as "operands" or "arguments") and produces a well-defined output value. The arity of the operation is determined by the number of operands.Binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive inverse and multiplicative inverse, are the most commonly studied. A constant is an operation of arity zero, also known as a nullary operation. The mixed product is an example of a 3rd order operation, also known as a ternary operation.So, there will be 22 children at the party and each table will have 1 child sitting on each side.
This means that at 1 table there will be sitting 4 children.(A) Ms Francis would have to rent 6 tables in order for everyone to have their own side.
Then,
4 × 6 = 24
(B) She could have all of the children sitting at their tables, each with their own side, but the sixth table would only have two other children.
Therefore, the answers to both the subparts are:
(A) Ms. Francis would have to rent 6 tables in order for everyone to have their own side.(B) She could have all of the children sitting at their tables, each with their own side, but the sixth table would only have two other children.Know more about mathematical operations here:

How to determine length of arcstop
Length of arc = ( ∅ / 360 ) * 2 * pi * r
1. length of arc AB
L = ( ∅ / 360 ) * 2 * pi * r
L = ( 70 / 360 ) * 2 * pi * 5

The annual tuition at a specific college was $20,500 in 2000, and $45,4120
in 2018. Let x be the year since 2000, and y be the tuition. Write an
equation that can be used to find the tuition y for x years after 2000. Use
your equation to estimate the tuition at this college in 2020.
y = 20500 + 24090(x - 1) can be used to find the tuition y for x years after 2000. The tuition at this college in 2020 was $5,02,300.
We assume that the rate of increase in the cost of tuition fee per year is linear and hence the tuition fees of subsequent years will be in an Arithmetic Progression. The formula for determining the nth term of an arithmetic sequence which is expressed as-
Tn = a + (n - 1)d
Where
a = first term of the sequence.
d = common difference.
n = number of terms in the sequence.
According to the question,
a = $20500 (amount in 2000)
From 2000 to 2018, the number of terms is 19, hence,
n = 19
Thus, T19 = 454120
Therefore,
4,54,120 = 20500 + (19 - 1)d
454120 - 20500 = 18d
18d = 433620
d = 433620/18
d = 24,090
Therefore, the equation that can be used to find the tuition y for x years after 2000, is as follows-
y = 20500 + 24090(x - 1)
Now, the number of terms between 2000 and 2020 is 21, hence
x = 21
y = 20500 + 24090(21 - 1)
y = 20500 + 481800
y = $502300
Therefore, the tuition at this college in 2020 was $5,02,300.

A can of soup is composed of 40% solids and 60% water. If a can of soup is mixed with two cans of water, what percentage of the mixture is water?
Assuming that a can of soup which has 60% water is mixed with two cans of water, the percentage mixture that is water is 87%.
What percentage is water?Assuming the total quantity of a can is 100 ml, the quantity of water in the can of soup would be:
= 60% x 100
= 60 ml
If two more cans of water are added, the total amount of water is:
= 60 + 100 + 100
= 260 ml
The percentage of water is:
= 260 / (100 + 100 + 100)
= 87%

How many zeros will be in the product of 7 times 5,000? Without calculating the answer, explain how to use place value strategies to find the number of zeros in the product
The number of zeros in the product of 7 and 5,000 is 3.
The place value is defined as the value of each digit in a given number.
Here, we are given that 7 is multiplied by 5000
We can see that in 5000, the hundreds, tens and units digits are all zero.
Also, we know that 0 multiplied by any number gives us a zero only.
Thus, when we multiply 5000 and 7, each digit of 5000 will be multiplied by 7.
We can thus see that there will definitely be at least 3 zeroes in their product.
when we 7 is multiplied by 5, the unit digit will not be 0 as 7 is an odd number.
Thus, there are 3 zeroes in the product of 7 and 5000.

A box turtle Marcos found is 0.115 of a meter long. What is this length in expanded form?
If a box turtle Marcos found is 0.115m long, then the length in expanded form is (0.1 + 0.01 + 0.005).
As per the question statement, a box turtle Marcos found is 0.115m long.
We are required to find out the expanded form of the length.
To solve this question, we need to know the procedure to convert a decimal into a fraction:
First, we will have to eliminate the decimal point and then, consider the digits in the same order as a complete number which will be our numerator. Secondly, we will use (10ⁿ) as our denominator where "n" is the number of digits on the right side of the decimal point in the original decimal number. Thus, 0.115 can be written as [tex]\frac{115}{1000}[/tex], since there are three digits after decimal point.
Now [tex]\frac{115}{1000}[/tex] can be written in the following manner as shown below.
[tex]\frac{115}{1000}=\frac{100+10+5}{1000}\\ or, \frac{115}{1000}=\frac{100}{1000}+\frac{10}{1000}+\frac{5}{1000}\\ or, \frac{115}{1000}=\frac{1}{10}+\frac{1}{100}+\frac{5}{1000}\\ or, \frac{115}{1000}=0.1+0.01+0.005[/tex]
Therefore, 0.115 can be written as (0.1 + 0.01 + 0.005) in its expanded form.
