Answer:

$A=128\ cm^2$

Step-by-step explanation:

we know that

The area of the polygon is equal to the area of a square plus the area of four congruent triangles

$A=b^2+4[\frac{1}{2}(b)(h)]$

where

$b=8\ cm\\h=4\ cm$

substitute

$A=8^2+4[\frac{1}{2}(8)(4)]$

$A=64+64=128\ cm^2$

Can u send picture with it pls so i can figure it out?

What are the two shapes

Step-by-step explanation:

rectangle: length times width

triangle: base times height divided by 2

parallelgram: Base times height

square: side times side

The distribution of the number of graduate students over the past 13 years in the math department was: 1 69 2 445 3 347 4 0269 5

Sergio [31]

Answer:

largest number os students = 73

smallest number of students is 16

Step-by-step explanation:

Distribution of student over the period of 13 year is given in the following table

first column represent the stem which are on tens digit while column 2 represent the leaf which are on one digit.

1 6 9

2 4 4 9

3 3 4 7

4 0 2 6 9

7 3

hence the graduate student number is calculated as

16, 19, 24,24,29, 33, 34,37,40,42,46,49,73.

hence from the obtained data largest and smallest number of students over a period of 13 year can be calculate

largest number os students = 73

smallest number of students is 16

Graph the linear equation and answer each of the following questions. y>2/3 x-2 What is the y-intercept? What is the slope (i

lozanna [386]

Answer:

(i)

y-intercept is -2

(ii)

slope is $\frac{2}{3}$

(iii)

slope is positive

(iv)

another point is (3,0)

Step-by-step explanation:

We are given equation as

$y=\frac{2}{3} x-2$

now, we can compare it with slope intercept form of line

y=mx+b

where

m is slope

b is y-intercept

we get

$m=\frac{2}{3}$

$b=-2$

So,

(i)

y-intercept is -2

(ii)

slope is $\frac{2}{3}$

(iii)

we can see that

$m=\frac{2}{3}$

is a fraction and positive

so, slope is positive

(iv)

we can select any random value of x and find y

that will give us second point

Let's assume

x=3

$y=\frac{2}{3}\times 3-2$

$y=2-2$

$y=0$

So, another point is (3,0)

(v)

Helppppp idk how to do that?

frozen [14]

Answer: a). 136 degree. b). A kite

Explanation:

360 = POR + OPT + ORT + 44

OPT = ORT = 90 (line TP and TR tangent to the circle)

360 = POR + 90 + 90 + 44
POR = 360 - 224
POR = 136

B). OPTR is a kite because OP = OR and TP = TR

Definition of a kite:

A quadrilateral whose 4 sides can be grouped into two pairs of equal sides that are adjacent to each other.
