A portable media can hold up to 9,000 songs. Therefore:

Kylie can add = 9000 – 832 = 8168

Lance can add = 9000 – 3 * 832 = 6504

So the difference is:

8168 – 6504 = 1664

Therefore lance can add 1664 fewer songs than kylie

Answer:

The total number of books in the school library is 800.

Given that, in a library at school, there are three nonfiction books for every seven fiction books and the number of nonfictional books=240.

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. The proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Let the total number of books be x.

Now, the ratio of fictional to nonfictional boos is 3:7

Total=3+7=10

So, 3/10 = 240/x

⇒3x=240×10

⇒3x=2400

⇒x=800

Therefore, the total number of books in the school library is 800.

Equal groups division with an unknown multiplier in mathematics refers to a division problem where you know the total and the number of groups, but not the number of items in each group. You solve it by dividing the total by the number of groups. This concept assists in understanding division and acts as a stepping stone to algebra.

In Mathematics, the term 'equal groups division with an unknown multiplier' refers to a division problem where you are given the total and the number of groups, but not the number of items in each group. This is a concept typically introduced in middle school Math.

For example, if you have 24 apples and want to divide them up into 4 equal groups, but you don't know how many apples will be in each group, that's division with an unknown multiplier. The solution would be to divide 24 (the total) by 4 (the number of groups), which gives you 6. So each group has 6 apples.

This concept helps students to better understand division and is often a precursor to learning about algebra, where the unknown multiplier is replaced with a variable.

The percent increase after decreasing the dimensions of a rectangle is 66.67%

The question asks for the percent increase in area when the dimensions of a rectangle are decreased, which necessitates understanding of area calculations and percentages. Initially, the rectangle had an area of 24 square feet, which reduced to 6 square feet upon decreasing each dimension by 2 units.

To find the percent increase, one should first understand that a decrease in area actually implies a percent decrease, rather than an increase.

Find the area of the original rectangle: 4 units x 6 units = 24 square feet

Find the area of the new rectangle: (4 - 2) units x (6 - 2) units = 8 square feet

Calculate the percent increase: ((24 - 8) / 24) x 100% = 66.67%

The square root of 106 is between 10 and 11. So, the two consecutive whole numbers are 10 and 11.

The student is asking about the whole numbers that the square root of 106 lies between. To determine this, we calculate the square roots of numbers near 106. The square root of 100 is 10 and the square root of 121 is 11. Therefore, the square root of 106 lies between 10 and 11. So, the two consecutive whole numbers that the square root of 106 lies between are 10 and 11.

Final answer:

To find Seth and Eric's current ages, we can set up two equations using the given information and solve them simultaneously.

Explanation:

To solve this problem, let's start by assigning variables to the ages of Seth and Eric. Let Seth's age be represented by 'S' and Eric's age be represented by 'E'. We are given that currently Seth's age is 4/5 the age of Eric:

S = (4/5)E

We are also given that twenty-one years ago Eric was twice as old as Seth:

E - 21 = 2(S - 21)

Now we can solve these equations simultaneously to find their current ages. Let's substitute the value of S from the first equation into the second equation:

E - 21 = 2((4/5)E - 21)

Simplifying the equation, we get:

E - 21 = (8/5)E - 42

Moving all the terms with 'E' to one side, we get:

(8/5)E - E = 42 - 21

Simplifying further, we get:

(3/5)E = 21

To solve for E, we can multiply both sides of the equation by 5/3:

E = (5/3) * 21 = 35

Now that we know Eric's age, we can substitute this value back into the first equation to find Seth's age:

S = (4/5) * 35 = 28

Therefore, Eric is currently 35 years old and Seth is currently 28 years old.

The equation of the given graph will be y=-3/2x+3 so none of the options will be correct.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

The point of intersection of the line and x-axis = (2,0)

The point of intersection of the line and y-axis = (0,3)

The slope of the graph or line

Slope = differcne in ys coordinate/difference in xs coordinate

Slope(m) = (3-0)/(0-2) = -3/2

Now equation of a line is given by

y = mx + c

Now keep point (2,0) and slope-3/2

0 = (-3/2)2 + c

c = 3

So, the equation would be

y = (-3/2)x + 3

Hence, The equation of the given graph will be  y=-3/2x+3

m - slope of line

c - intercept of line on y - axis.

According to the question -

The slope of line = [tex]\frac{3-0}{0-2}[/tex] = [tex]\frac{-3}{2}[/tex]

c = 3

Substituting the values in the general equation of line, we get -
