Answer:
1.10 litres
Step-by-step explanation:
0.25 + 0.3 = 0.55
0.55 + 0.75 = 1.30
1.30 - 0.20 = 1.10
Answer:
5.656854x^2y^2
Step-by-step explanation:
√32x^2y^2
Simplifies to:
5.656854x^2y^2
=5.656854x^2y^2
Answer:
Step-by-step explanation:
Each angle of regular pentagon = 108
Given triangle is an isosceles triangle
In this triangle,
y + y + 108 = 180 {angle sum property}
2y + 108 = 180
2y = 180 - 108
2y = 72
y = 72/2
y = 36
keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above
since we know that's its slope, then
so then we're really looking for the equation of a line whose slope is -2 and passes through (2 , 1)
