50% or 1/2 of 4 is 2 50% or 1/2 of 6 is 3 so then just add them to the respective number since its going up by 50% or 2 in by 3 in \[\frac{ 6 }{ 9}\]

The size of the image is 4 inch by 6 inch

Size of the image scale up by 50%

4 in increased by 50 % = New length = x

\frac{x}{4}=\frac{50}{100}

Cross multiply, we get

100 x = 4(50)

100x = 200

Divide both side by 100, to find x

x = 200/100

x = 2

New length = original length + increased length

New length = 4 + 2 = 6 in

6 in increased by 50 % = New length = y

\frac{y}{6}=\frac{50}{100}

Cross multiply, we get

100 y = 6(50)

100y = 300

Divide both side by 100, to find y

y = 300/100

y= 3

New length = original length + increased length

New length = 6 + 3 = 9 in

So New dimensions are 6 in by 9 in

What single transformation maps ∆ABC onto ∆A'B'C'? A. rotation 90° clockwise about the origin B. rotation 90° counterclockwise a
Klio2033 [76]

Answer:

B. rotation 90° counterclockwise about the origin.

Step-by-step explanation:

Transformation is the process by which the size or orientation of a given figure is altered without any effect on its shape. Examples are; rotation, reflection, translation and dilation.

Rotation is the process of turning a figure about a reference point called the origin. While reflection is turning a figure about a line to produce its image.

In the given question, ∆ABC is  mapped onto ∆A'B'C' by rotating it at 90° counterclockwise about the origin.

the perimeter of a rectangular garden is 50 meters and area is 150 meters square . calculate the length and breadth of the garde
makkiz [27]

Answer: The two sides are 15m and 10m.

Step-by-step explanation:

Area = l x w

150 = l x w

There are two solutions for l

l 1= P/4+1/4√P2﹣16A

=50/4+1/4·√50^2﹣16·150=15m

l2 = P/4﹣1/4√P2﹣16A

=50/4﹣1/4·√50^2﹣16·150=10m
