We know that the mixture has 14 mm of ink. Of these, 35% are blue pigment, hence the mixture contains 4.9 mm of blue ink. Ink A contains 10%*4mm=0.4mm of blue ink. The difference, 4.5 mm of blue ink must have come from ink B. Thus ink B contains 4.5 mm of blue ink and is in total 10mm. After that, we can calculate the percentage; we divide 4.5/10=0.45 and this is the ratio of blue ink to total ink (in Ink B). If we transform it to percentages it is 45%

Answer:
5√3 ft = 8.8 ft (to the nearest tenth foot)
Step-by-step explanation:
The formula for the area of a square is A = s², where s is the length of any one of the sides of the square.
If A = 75 ft² = s²2, then the side length s is s = √75 ft.
Simplified, that comes out to s = (√25)(√3) = 5√3 ft.
To the nearest tenth of a foot, that comes out to s = 5(1.732) = 8.7 ft.
