Answer:

698 cm²

Step-by-step explanation:

The volume is given by ...

V = LWH

Filling in the given values, we have ...

1020 = (17)(5)y . . . . . . . using L=17, W=5, H=y

y = 1020/(17·5) = 12

The surface area is given by ...

A = 2(LW +H(L+W))

A = 2(17·5 +12(17+5)) = 2(85 +264) . . . . . . . using L=17, W=5, H=y=12

A = 698 . . . . square centimeters

Given m||n, find the value of x.<br> (9x-5)(6x+20)

xxTIMURxx [149]

Answer:

5/9 & -10/3

Step-by-step explanation:

Set each to 0 and solve:

9x-5 = 0

9x=5

x=5/9

6x+20=0

6x=-20

x=-20/6

x= -10/3 or -3 1/3

Graph the image of this figure after a dilation with a scale factor of 12 centered at the origin.

andreev551 [17]

Answer:

The vertices of image are (-48,48), (24,24) and (72,96).

Step-by-step explanation:

From the figure it is noticed that the vertices of triangle are (-4,4), (2,2) and (6,8).

The scale factor is 12 and the dilation is about the origin.

If a figure is dilated about the origin with scale factor k, then

$(x,y)\rightarrow (kx,ky)$

Since the scale factor is 12.

$(x,y)\rightarrow (12x,12y)$

The vertices of image are

$(-4,4)\rightarrow (-48,48)$

$(2,2)\rightarrow (24,24)$

$(6,8)\rightarrow (72,96)$

Therefore the vertices of image are (-48,48), (24,24) and (72,96). The graph of image is shown below.

M angle IMJ= help me please thanks

emmainna [20.7K]

The measure of angle IMJ is 62.5 degrees

<h3>How to solve for IMJ?</h3>

To solve for angle IMJ, we make use of the following arc intercept theorem.

Angle IMJ = 0.5 * (Arc IJ + Arc LK)

So, we have:

Angle IMJ = 0.5 * (40 + 85)

Evaluate the product

Angle IMJ =62.5

Hence, the measure of angle IMJ is 62.5 degrees
