Step-by-step explanation:
£280 is 7% of 4000 so £4000 euro more would be 4000/280 = 14
Answer:
Lets solve = 3/5 ÷ 1/2
3/5 ÷ 1/2
= 3/5 × 2/1
= 3 × 2/5 × 1
= 6/5
In mixed fraction its

____________________
Now lets solve "a" option
3/5 × 2
= 3 × 2/5 × 1
= 6/5
In mixed fraction

So option a = 3/5 x 2/1 is ur answer
Answer:
The line passes (2, 5) and (4, 7) has slope:
S = (7 - 5)/(4 - 2) = 2/2 = 1
The line passes (1, 7) and (-4, 2) has slope:
S = (2 - 7)/(-4 - 4) = 5/-5 = -1
The multiplication of two slope is 1 x (-1) = -1
=> Two lines are perpendicular
Hope this helps!
