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

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form [tex]y/x=k[/tex] or [tex]y=kx[/tex]

In this problem

Jorge bought [tex]16[/tex] apples for [tex]\$8.00[/tex]

This is a direct variation problem

Let

x-----> the number of apples purchased

y-----> the total cost

[tex]y/x=k[/tex]

The value of k is equal to the value of the slope m

Substitute

[tex]8/16=k[/tex]

[tex]k=0.5\frac{\$}{apple} [/tex]

The linear equation is

[tex]y=0.50x[/tex]

using a graphing tool

see the attached figure

The answer in the attached figure

Current worth of the investment = [tex]1.2(10^{7} )[/tex]

Worth of the investment 20 years before = [tex]9.6(10^{5} )[/tex]

To find the number of times greater, we have to divide.

Number of times greater = [tex]\frac{current worth}{worth 20 years before}[/tex]

[tex]=\frac{1.2(10^{7} )}{9.6(10^{5} )}[/tex]

[tex]=\frac{1.2(10^{2} )}{9.6}[/tex]

[tex]=\frac{120}{9.6}[/tex]

= 12.5

Hence, the correct option is (b).

The inequality that would be a good  representative of the given constraints is; s ≥ 30 + c

We are told that the company wants to sell at least 30 subscriptions. This means greater than or equal to 30 subscriptions,s.

Now, the 30 subscriptions,s is for every subscriptions,c they give away.

Therefore, it means that if they give 0 subscriptions,c out, the minimum subscriptions,s must be 30. Thus, the inequality that represents the given problem is expressed as;

s ≥ 30 + c

Answer:

4. [tex]f,g\text{ and }h[/tex] only.

Step-by-step explanation:

We have been given an expression [tex]f+2g+\frac{h}{4}-7[/tex]. We are asked to find the variables in the given expression.

We know that variable is a symbol or letter that represents an unknown value in a mathematical expression.

We can see that in our given expression [tex]f,g\text{ and }h[/tex] are unknown, therefore, these are variables for our given expression.

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%

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 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.
