Explanation:
Form a horizontal line as shown below (see attached image). This forms 2 separate smaller rectangles
The total area is therefore 32+9 = 41 cm^2
You can say "square cm" or "sq cm" in place of the "cm^2".
Answer:
First mechanic worked 20 hours and second mechanic worked 5 hours
Step-by-step explanation:
Let the number of hours the first mechanic worked =
Let the number of hours the second mechanic worked =
Therefore, we can write 2 equations and then solve them simultaneously:
Rearranging the first equation:
and substituting into the second equation to find :
Now sub into the first equation to find
Therefore, first mechanic (a) worked 20 hours and second mechanic (b) worked 5 hours
Answer:
There were 49 questions on this Geometry test.
Step-by-step explanation:
You can start by setting up a proportion:
x = total number of questions on Geometry test
=
Now, to solve for x, cross multiply:
75.51x = 3700
Finally, isolate x and solve:
x = 49.0001324328
This is very close to 49.
