Answer:
Step-by-step explanation:
Ratios of perimeters is a one-to-one measure. From the figure on the left to the one on the right the ratio of the one-to-one measure is 45/25 which reduces to 9/5.
Area is a squared measure. Once we have the perimeter reduced (we do), we square those perimeter measures to find the area ratio.
Answer:
The standard deviation of the numbers is 2.24

Answer:
GH=5
HI=5
IJ=5
JK=9
Step-by-step explanation:
GK=24
HJ=10
GH=HI=IJ.
Let GH, HI, IJ be x
therefore,
HI+IJ=10
=>x+x=10
=>2x=10
=>x=10/2
=>x=5
HI=IJ=GH=5
GH+HI+IJ+JK=GK
=>5+5+5+JK=24
=>15+JK=24
=>JK=24-15
JK=9
Use either the distance formula or the Pythagorean Theorem. i suggest you plot the 2 given points and draw the line segment CD connecting these points.
What is the horiz. distance between the 2 points? The vertical distance?
If you'd square the horiz. distance and also square the vertical distance, and then add these two squares together, and finally take the positive square root of this sum, you'll have the distance cd. Round it off to the nearest tenth.
