Answer:
420
Step-by-step explanation:
Amount in the 45% solution + amount in the 70% solution = amount in the 45% solution
0.15 × 350 + 0.70 × V = 0.45 × (350 + V)
52.5 + 0.70V = 157.5 + 0.45V
0.25V = 105
V = 420
You need 420 mL of the 70% solution.
Answer:
44 wins
Step-by-step explanation:
47+39+x/100*70
What exactly is we supposed to do?
I'll answer it after u answer my question
The two quadrilaterals are similar. Which means the ratios of respective sides of two quadrilaterals will be the same.
So, for the given quadrilaterals, ratio of sides JF and TF of quadrilateral RJFT will be equal to the ratio of sides YP and AP of quadrilateral SYPA. Mathematically, we can write:

So the measure of TF will be 96mm
