which of the following properties could be used to rewrite the expression (2/3•1/5)•5/2 as 2/3•(5/2•(5/2•1/5) sorry to ask Su ma
slamgirl [31]
The original expression is given by:
 ( \frac{2}{3}*\frac{1}{5})*\frac{5}{2}
 The correct way to rewrite the expression is given by:
 \frac{2}{3}*(\frac{5}{2}*\frac{1}{5})

 For this, we use two properties:

 Associative property:
 The way of grouping the factors does not change the result of the multiplication:
 \frac{2}{3}*(\frac{1}{5}*\frac{5}{2})

 Commutative property:
 
The order of the factors does not vary the product:
 \frac{2}{3}*(\frac{5}{2}*\frac{1}{5})

iogann1982 [59]

The total budget for the student film was $1300 and $481 was spent on costumes

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Let x represent the total budget for the student film.

The student spent $481 on costumes, which was 37% of their total budget, hence:

37% of x = 481

0.37x = 481

x = $1300

The total budget for the student film was $1300 and $481 was spent on costumes

A rectangle is reduced by a scale factor of One-fourth.
Dvinal [7]

The ratio of the area of the smaller rectangle to the area of the larger rectangle is 1:16

Area of a rectangle

The formula for calculating the area of a rectangle is expressed as:

A = length * width

For the large triangle

Area = 16 * 12

Area of large triangle = 192 square units

For the smaller rectangle

Area = 4 * 3

Area. of small rectangle = 12 square units

Ratio = 12/192 = 1:16

Hence the ratio of the area of the smaller rectangle to the area of the larger rectangle is 1:16

Which of the following numbers are not expressed in scientific notation? Select all
EleoNora [17]
The answer is B.

Explanation:

In scientific notation, a number must be put in an expression multiplied by ten to a given power. An example of this would be 3 x 10^2 because it is a form of saying 3 x 100. In B, 10 is accompanied by a degrees sign instead of a power. Therefore, this expression is not shown in scientific notation.
