-5 because a negative plus a negative is a positive this is why it is the right answer
Problem
Is 4.55 and 1.23456 a rational number
Solution
4.55 can be written as:
455/100 so then it could be a rational number
For the second number we have: 1.23456
And we can write this number as:
123456/100000
So then is also ratioanl
6 plates with 3 spoons or 9 plates with 2 spoons
Triangles internal angles will always equal 180 degrees.
So, with that being said we can add up the known angles and subtract them from 180 to get our missing angle
28+67 = 95
180-95 = 85
so angle P is 85 degrees
Hypotenuse² = perpendicular² + base²
H² = 20²+21²
H²= 400+441 = 841
H = √841
H = 29 cm
