Answer:
The students points will decrease 10 points in 4 days
Step-by-step explanation:
In 2 days he loses 5 points. So for 4 days all you have to do is double the amount of points because the amount of days have doubled
Answer: On a coordinate plane, 2 triangles are formed with a line with points (0, 2) and (x, y). A triangle has a rise of 1 and run of 2. Another triangle has a rise of 3 and run of 6.
Step-by-step explanation: Hope this helped if not just reply, I'll answer when I get a chance
Answer:
The length of the yard is 
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The perimeter of the yard required to be fenced is equal to


so

solve for x



Find the length of the yard

Answer:
No solution
Step-by-step explanation:
These are parallel lines, which never meet. Therefore, there is no solution.
A)We have been given →
Hieght of trough = 5m
length of trough = 6m
Breadth of trough = 4m
so , As the top is opened for feeding animals.
Area of base = length× Breadth
= (6×4) m²
= 24 m²
Area of Front and back face = Hieght × length
= (5×6) m²
= 30m²
Area of side faces = hieght × Breadth
= (5×4) m²
= 20 m²
____________________________________
B)Total Surface area of trough will be given by formula - 2(lb+bh+hl)
= 2{(6×4)+(4×5)+(5×6)}
= 2{24+20+30}
= 2×74
= 148 m²
As we have been told top is open , so we will deduct top from Total surface Area to obtain Surface area →
(148-24) m²
(Area of top will be same as base area , that is 24m² as we have solved in A)
= 124m²
Answer→ Surface area of trough is 124m²
