Sean first thought that his hand was 20 cm so:
20cm
When he measures with a ruler, he gets 18 cm so:
18cm
The equation is really simple, and you basically do:
20/20 - 18/20 = 2/20 = 1/10 = 10%
The equation is:
1- x/y
x equals the new number
y equals the original number
Answer:
1 is the coefficient of the last term in the binomial expansion

Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
I believe the measure of angle PQR would be 50 degrees. The triangle is a right triangle, meaning one angle is 90 degrees.
1) 90 + 40 = 180
90 + 40 = 130
2) 180 - 130 = 50
Therefore, Q is 50 degrees. The whole triangle is 180 degrees.
