san4es73 [151]

Answer:

Michelle purchased 25 audio files in January. The percent increase is 60%

Solution:

Given Data:

Michelle purchases = 25 audio files in January

Again purchased = 40 audio files in February

We need to find the percent increase for the given data.

Step 1:

Use the formula for percent change ,

$=\frac{\text { amount of change }}{\text { original amount. }}$

Step 2:

First we find the amount of change from the question.

Amount of change = 40 – 25

By subtracting, we get 15.

Step 3:

substitute the values in formula we get,

Formula percent change = $\frac{15}{25}$ = 0.6

Percent = 0.6 $\times$ 100 = 60 %.

Result:

Michelle purchased 25 audio files in January. And In February she purchased 40 audio files. Hence the percent increase is 60%.

Montano1993 [528]

Answer:

The triangle and trapezoid area formulas have One-half in them.

In the trapezoid formula, the bases are added.

Step-by-step explanation:

Topic: Plane Shapes

Basically, the requirement of the question is to compare area of shapes. The shapes are

Trapezoid
Triangle
Parallelogram
Rectangle

The Area of a Trapezoid is $(\frac{a + b}{2} )h$ where a and b are the bases of the trapezoid and h is the height

The Area of a Triangle is $\frac{bh}{2}$ where b and h are the base and the height of the triangle respectively

The Area of a Parallelogram is $b * h$ where b and h are the bases and the height of the parallelogram

The Area of a Rectangle is $l * b$ where l and b are the length and the breadth of the triangle respectively

Checking option a through e

A. The triangle and trapezoid area formulas have One-half in them.

True; Area of a Triangle is $\frac{bh}{2}$ while Area of a Trapezoid is $(\frac{a + b}{2} )h$

B. The parallelogram and rectangle formulas are both the same.

False; Area of a Parallelogram is $b * h$ while Area of a Rectangle is $l * b$

C. In the parallelogram formula, the bases are added.

False; The basis are not added

Area of a Parallelogram is $b * h$

D. In the trapezoid formula, the bases are added.

True; Area of a Trapezoid is $(\frac{a + b}{2} )h$

E. In the triangle formula, the sides are added, then multiplied by One-half.

False; Area of a Triangle is $\frac{bh}{2}$

Because it is three-dimensional, a form has these three spatial measurements: height, width, and ________.

AlexFokin [52]

Considering that it is a three-dimensional form, it's spatial measurements are height, width and length.

<h3>What are the measurements of a three-dimensional form?</h3>

A two-dimensional form has two dimensions, width and length. When there are three dimensions, the height is added.

In this case, height and width are already listed, hence the length is missing.
