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.

An 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:

In 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.

The length of the base of the triangle is 1 1/5 inches

The area of a shape is the amount of space on the shape

The given parameters are

Area = 3/4 square inches

Height = 1 1/4 inches

The length of the base of the triangle is calculated as

Base = 2 * Area/Height

Substitute the known values in the above equation

This gives

Base = 2 * (3/4)/(1 1/4)

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.

Mario's score in the video game is 174.

Mario's score is a function of the number of points started with, the point per coin, the point per gem , number of gem and coins found. The mathematical operations that would be used are addition and multiplication.

Addition is the process of determining the sum of two or more numbers. Multiplication is the process of determining the product of two or more numbers.

Mario's score = beginning point + (number of gold coins x score per gold coin) + (number of gems x score per gem)

Mario's score = 100 + 3c + 2g

Mario's score = 100 + (3 x 8) + (2 x 25)

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.

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.

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.

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.

Using translation concepts, we have that:

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.
