Side of a square = 4n
Side of the smaller square = 4n÷2 = 2n
Perimeter of one smaller square = 2n x 4 = 8n
Perimeter of 20 smaller squares = 8n x 20 = 160n
------------------------------------------------------------------------------
Answer: Perimeter of all the 20 smaller squares = 160n
------------------------------------------------------------------------------
Answer:
55 cookies in 80 mins
Step-by-step explanation:
1 hour has 60 mins
so 25/60=0.417
0.417/3=0.139
0.139x4=0.556
so he can eat 55 cookies in 80 mins
The other equality which must be stated by Jose is that angles BAC and BAE are congruent and their measures are equal.
<h3>What other congruence statements must Jose state?</h3>
It follows from the task content that Jose is trying to prove the congruence of both triangles by means of the Side-Angle-Side congruence theorem.
It therefore follows that since, Jose has identified that the ratio of corresponding sides are equal as indicated in the task content, the equality which Jose has to state is the angle congruence equality.

If the two of you can wash 1 car in 6 minutes:
It will take you 10 minutes to wash the car alone
take your friend 15 minutes to wash the car alone
Let the duration you can work be represented by y
Let the duration your friend can work be represented by x
You can wash a car 1.5 times as fast as your friend
That is, y = 1.5x
Working together, the two of you can wash 1 car in 6 minutes
This can be represented by the equation

Substitute x = 1.5y into the equation above

It will take you 10 minutes to wash the car alone
Substitute y = 10 into x = 1.5y
x = 1.5(10)
x = 15 minutes
It will take your friend 15 minutes to wash the car alone
