Answer:
Alisha
Step-by-step explanation:
Speeds:
Bill:
315/7 = 45 mph
Alisha:
235/5 = 47 mph
Joanna:
414/9 = 46 mph
3/4+3/4+3/4
=(3+3+3)/4
=9/4 or 2/1/4
Answer:
y = 44
Step-by-step explanation:
Well if y varies directly with x it means that when y increases x increase and if y decrease x also decreases.
So let us put this in a equation,
<em>y = kx
</em>
where 'k' is constant
so <em>k = y/x</em>
let us put the figures of x and y from given first statement;
x = 7 and y = 18
so, k = 18 / 7
which means, k = 2.57
lets put this value of k in the equation above,
we know from statement that, x = 17 and k = 2.57
so, y = 2.57 (17)
which means, y = 43.71
or we can round it off to, y = 44
56% of 80
56/100 X 80/1= 224/5 = 44 4/5 or 44.8
