<u>Answer:</u>

The correct answer option is b. Perimeter = 19.2 units, Area = 22 units $^2$ .

<u>Step-by-step explanation:</u>

We are given a pentagon ABDEC and we are to find its perimeter.

From the given figure, we can clearly see that the pentagon can be divided into two shapes, a square and a triangle. One side of each of these shapes will be excluded from the perimeter.

Distance of AB = $\sqrt{(4-1)^2+(6-4)^2} = \sqrt{13} =3.6$

The length of AB and AC are same and the BD, DE and CE are same (4 units).

Perimeter of pentagon ABDEC = 4 + 4 + 4 + 3.6 + 3.6 = 19.2 units

Area = (area of ΔABC) + (area of square BDEC)

= $(\frac{1}{2} *4*3)+(4*4)$

= 22 units $^2$

Parallelogram JKLM has vertices J(-1, 6), K(0, 9), L(6, −3), and M(3, −3). What is the coordinates of the image if the parallelo

Digiron [165]

Answer: $(\dfrac13,-2),\ (0,-3),\ (-2,1),\ (-1,1) .$

Step-by-step explanation:

Transformation rule for dilation:

$(x,y)\to(kx,ky)$ , where k = scale factor

Given : Scale factor = $-\dfrac13$

Parallelogram JKLM has vertices J(-1, 6), K(0, 9), L(6, −3), and M(3, −3)

Vertices after dilation:

$(-1,6)\to(-1\times\dfrac{-1}{3},6\times\dfrac{-1}{3})=(\dfrac13,-2)$

$(0,9)\times(0\times-\dfrac13,9\times-\dfrac13)=(0,-3)$

$(6,-3)\to(6\times-\dfrac13,\ -3\times-\dfrac13)=(-2,1)$

$(3,-3)\to (3\times-\dfrac13,\ -3\times-\dfrac13)=(-1,1)$

Hence, the coordinates of the image if the parallelogram = $(\dfrac13,-2),\ (0,-3),\ (-2,1),\ (-1,1) .$

1. When you measure the length of an object to the eighth of an inch and again to the fourth of an inch, which measurement is mo

sladkih [1.3K]

Answer:

The eighth of an inch scale measures more precisely.

Step-by-step explanation:

An eighth of an inch means that one inch is divided into 8 equal lengths on the scale i.e. the minimum length that can be measured is $\frac{1}{8} =0.125$ inch.

Again a fourth of an inch means that one inch is divided into 4 equal lengths on the scale i.e. the minimum length that can be measured is $\frac{1}{4} =0.25$ inch.

Therefore, the eighth of an inch scale measures more precisely as it can measure more small measurements. (Answer)
