Answer:
610 cm
Step-by-step explanation:
78.9 x 100 = 7890 cm 85 x 100 = 8,500 cm
8,500 - 7890 = 610 cm
In geometry, transformation involves changing the position and/or size of a shape.
<em>The transformation that will change the size of ABCD is dilation.</em>
There are four transformations in geometry:
- Translation
- Reflection
- Rotation
- Dilation
Of all types of transformation, dilation will change the size of the shape,
The new shape will either be enlarged or reduced
<em>Either ways, the size of the shape will be altered.</em>
<em>When the size is altered, the perimeter will not remain the same.</em>
<em />
Hence. dilation will change the perimeter of ABCD.

Answer:
a) 279 b)254
Step-by-step explanation:
Mean = 269 days
standard deviation = 8 days
let n be the pregnancy lenght.
using normal distribution formula
z = (n – mean)/ standard deviation
n = z * standard deviation + mean
Now, z values for the top 12% has to be found using a z table.
The top 12% means 88% of area under the curve. In this case z = 1,176
n = 1,176 * 8 + 269
n = 278.4 = 279
The bottom 3% means 97% of area under the curve. In this case z = -1,882
n = -1,882 * 8 + 269
n = 253.94 = 254
Answer:
Step-by-step explanation:
interchange x and y
y= 1/(x - 2)
x = 1 / (y - 2) Multiply both sides by y - 2
x(y - 2) = 1 Remove the brackets
xy - 2x = 1 Add x to both sides
xy = 1 + 2x Divide by x
y = (1 + 2x)/x
The brackets have been destroyed. The answer is as I've given it.
y = (1/x) + 2
