Nina wants to download games for her video game console. Older games cost 150 points and new releases cost 600 points. Nina has 6000 points to use. The equation 150a+600b=6000, where a is the number of older games and b is the number of new releases, models the situation. How many older games can she download if she downloads one new game? four new games?
Considering the definition of an equation and the way to solve it, Nina can download 36 older games and 24 older games if she downloads one and four new games respectively.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.
The solution of a equation means determining the value that satisfies it and the equality is true. To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.This caseIn this case, Nina wants to download games for her video game console. Older games cost 150 points and new releases cost 600 points. Nina has 6000 points to use.
The equation 150a+600b=6000, where a is the number of older games and b is the number of new releases models the situation.
If Nina downloads one new game, that means that the value of the variable "b" is 1. Substituting in the equation that models the previously mentioned situation, and solving, you obtain:
150a+600×1=6000
150a + 600=6000
150a= 6000 - 600
150a= 5400
a= 5400÷150
a= 36
If Nina downloads four new game, that means that the value of the variable "b" is 4. Substituting in the equation that models the previously mentioned situation, and solving, you obtain:
150a+600×4=6000
150a + 2400=6000
150a= 6000 - 2400
150a= 3600
a= 3600÷150
a= 24
Finally, Nina can download 36 older games and 24 older games if she downloads one and four new games respectively.

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,

This diagram shows a pre-image △ABC and its image, △A′′B′′C′′ , after a series of transformations.
Select from the drop-down menus to correctly complete the statements.
△ABC is
1. reflected across the y-axis.
2. rotated 90 degrees counterclockwise about the origin.
3. translated 4 units right
to become △A′B′C′. Then △A′B′C′ is
1. reflected across the x-axis.
2. reflected across the line y = x
3. rotated 90 degrees counterclockwise about the origin
to become △A′′B′′C′′ . Because the transformations are
1. both rigid
2.not both rigid,
The pre-image and image are
1. congruent
2. not congruent
Using translation concepts, we have that:
△ABC is 3. translated 4 units right to become △A′B′C′. Then, △A′B′C′ is 3. rotated 90 degrees counterclockwise about the origin to become △A′′B′′C′′ .Because the transformations are both rigid, the pre-image and the image are congruent.What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
On the translation of △ABC to △A′B′C′, the rule applied to the vertices is:
(x,y) -> (x + 4, y).
Hence it was translated 4 units right.
On the translation of △A′B′C′ to △A′′B′′C′', the rule is given by:
(x,y) -> (-y,x).
Hence it was rotated 90 degrees counterclockwise about the origin.
The triangle keeps the same size after the translations, hence:
Because the transformations are both rigid, the pre-image and the image are congruent.

You need a value less than 23.5 or greater than 27.2.
Given the time in his first four races is: 24.7 , 23.5 , 25.6 , 27.2 seconds.
To find the time for her race which would make a higher difference, we need to make use of range.
The range formula is frequently employed in statistics to ascertain the range provided in a specific data set. The formula finds the difference between the lowest and highest value, which aids in locating the set's center. In distribution, a wide range denotes increased variability while a narrow range denotes lower variability. The mean, median, and mode are among the additional statistical concepts included in the range formula.
The range is the difference between the highest and lowest value. In this case, the highest and the lowest numbers are 27.2 and 23.5 seconds.
To make a larger range, we simply need to pick a number smaller than 23.5 or larger than 27.2. This will produce a larger difference (or range).
Hence we acquired the desired result.

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 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.

Find the distance between the points J(-8, 0) and K(1, 4). Answer in simplest exact form.
What’s the exact distance?
Answer:
distance = [tex]\bf \sqrt{97}[/tex] units
Step-by-step explanation:
To find the distance between two points given their coordinates, we can use the following formula:
[tex]\boxed{\mathrm{distance} = \sqrt{(x_1-x_2)^2 + (y_1 - y_2)^2}}[/tex],
where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are coordinates of the two points.
The two points we are given are:
• J(-8, 0)
• K(1, 4).
Using these coordinates and the formula above, we can calculate the distance between the points:
distance = [tex]\sqrt{(-8 - 1)^2 + (0 - 4)^2}[/tex]
= [tex]\sqrt{(-9)^2 + (-4)^2}[/tex]
= [tex]\sqrt{81 + 16}[/tex]
= [tex]\bf \sqrt{97}[/tex]
Therefore, the distance between J and K is [tex]\bf \sqrt{97}[/tex] units.

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.
