Leon usually does very well on tests, but he failed his most recent math exam. His teacher was very upset by Leon's performance

kondor19780726 [428]

Answer:

situational

Step-by-step explanation:

Based on the information provided within the question it seems that Leon's teacher made a situational attribution about his test performance. This term refers to when certain people believe that an individual's actions or behaviors are caused by a specific or various situational factors. Which is what his teacher is thinking by believing that his performance was affected by some problem or sickness (situational factors).

It gets cut off but it says ' Write the number marked with an arrow on the number line below as an improper (top-heavy) fraction

Anit [1.1K]

Answer:

1.2

Step-by-step explanation:

it's 1.2 because

the marked parts on the number line represent a fraction of the whole

so in writing this

it will be decimals

and wen the marked lines between 0 and 1 are counted it is 4

so starting each marked line represent 2

0.2,0.4,0.6,0.8,1,1.2,1.4,......

so from 1 the next marked part is 1.2

so the answer is <u>1.2</u>

This trapezoid has been divided into two right triangles and a rectangle.

jok3333 [9.3K]

The area of the triangle on left is in²: 9

The area of the triangle on the right is in²: 9

The area of the rectangle is in²: 108

The area of the trapezoid is in²: 126

<h3>Area of Compound Shapes</h3>

This exercise requires your knowledge about the area of compound shapes. For solving this, you should:

Identify the basic shapes;
Calculate your individual areas;
Sum each area found.

For finding the area, the steps are presented below.

STEP 1 - Identify the basic shapes.

This trapezoid is composed of two triangles and one rectangle. Therefore, you should sum the area of these geometric figures.

STEP 2 - Find the area of the triangle.

Area of the triangle - $A_{triangle}=\frac{b*h}{2}$ . The figure shows:

b= length of the base= 2in

h=height=9 in

Then, $A_{triangle}=\frac{b*h}{2}=\frac{2*9}{2} =\frac{18}{2}=9 in^2$

Note that the triangles are equals, consequently, they present the same values for the area.

STEP 3 - Find the area of the rectangle.

Area of the rectangle- $A_{rectangle}={b*h}$ . The figure shows:

b= length of the base= 12 in

h=height= 9in

Then, $A_{rectangle}={b*h}=12*9=108 in^2$ .

STEP 4 - Find the area of the trapezoid.

$A_{trapezoid}=2*A_{triangle}+1*A_{rectangle}\\ \\ A_{trapezoid}=2*9+1*108\\ \\ A_{trapezoid}=18+108\\ \\ A_{trapezoid}=126in^2$
