The answer is 25.84 for the difference
34.44 work right to left
-8.60
--------
25.84 u cant minus 6 from 4 so u change the 34 to 33 and .4 to 1.4 the minus to get .8, cant minus 8 from 3 so make 33 into 2(13) to get 5 and u would just leave the 2 in front because u dont subtract anything from it
Problem 1
Draw a straight line and plot X anywhere on it.
Use your compass to trace out a circle with radius 1.5 cm. The circle intersects the line at two points. Let's make Y one of those points.
Also from point X, draw a circle of radius 2.5
This second circle will intersect another circle of radius 3.5 and this third circle is centered at point Z.
Check out the diagram below to see what I mean.
=====================================================
Problem 2
Draw a straight line and plot L anywhere on it.
Adjust your compass to 4 cm in width. Draw a circle around point L.
This circle crosses the line at two spots. Focus on one of those spots and call it M.
Draw another circle centered at point M. Keep the radius at 4 cm.
The two circles intersect at two points. Focus on one of the points and call it N.
The last step is to connect L, M and N to form the equilateral triangle.
See the image below.

Problem 3
I'm not sure how to do this using a compass and straightedge. I used GeoGebra to make the figure below instead. It's a free graphing and geometry program which is very useful. I used the same app to make the drawings for problem 1 and problem 2 earlier.
a. The formula for the area of rectangle is:
A = l w
so given that A = 3/5 m^2 and w = 2/5 m,
l = A / w
l = (3/5 m^2) / (2/5 m)
l = 3/2 m or 1.5 m
b. We take the ratio l/w:
l/w = (3/2 m) / (2/5 m)
l/w = 3.75
So the length is 3.75 times greater than width
Answer:
C. 151
Step-by-step explanation:
Since there are 6 sides on a die, and one of them is 3, the chance of rolling a 3 is 1/6.
To estimate how many times Susan rolled a 3, multiply 888 by 1/6:
888(1/6)
= 148
So, Susan rolled 3 on the die around 148 times.
This is closest to answer choice C. 151
