An investment is currently worth 1.2×107 dollars . Twenty years ago, the investment was worth 9.6×105 dollars. How many times greater is the value of the investment today than the value of the investment twenty years ago? a. 0.125
b. 12.5
c. 125
d. 12,500
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).

What are proportions?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.

what's the square root of 44
By decreasing each dimension by 2 units, the area of the rectangle decreased from 24 square feet to 6 square feet. Find the percent increase
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%

Jorge bought 16 apples for $8.00. Let x represent the number of apples purchased, and let y represent the total cost. Graph the line that represents the proportional relationship.
(it doesn't have a graph because i need to graph it)
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]

what is equal groups division with an unknown multiplier mean?
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.
Explanation: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.

Look at the picture. Kylie has 832 songs on her portable media player. Lance has 3 times as many songs. how fewer songs can lance add to his player than Kylie can add to hers
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
