Given the dimensions of 72 yards by 1.5 yards, we can find that the total area of material the manufacturer has is 72 x 1.5 = 108 sq. yards. Dividing this by the 2.7 sq. yards required per shirt, they can make 108/2.7 = 40 shirts.

Stacy and Neil painted 280 ft2 of their living room wall with 45 gallon of paint. How many square feet can they paint with 3 gal
Alecsey [184]

Answer:

They can paint 18. 66 sq ft with 3 gallons of paint.

Step-by-step explanation:

Total area painted = 280 sq ft

Total gallons of paint used = 45

So, 45 gallons of paint painted 280 sq ft.

⇒ By UNITARY METHOD,

1 gallon of paint paints (\frac{280}{45} ) sq ft

So, area painted by 1 gallon = 6.22 sq ft

⇒ area painted by 3 gallon = 6.22 sq ft x 3 = 18. 66 sq ft

So, they can paint 18. 66 sq ft with 3 gallons of paint.

Express the complex number in trigonometric form. -6 + 6 square root of 3 i ?
bagirrra123 [75]
\bf \begin{array}{clclll}&#10;-6&+&6\sqrt{3}\ i\\&#10;\uparrow &&\uparrow \\&#10;a&&b&#10;\end{array}\qquad &#10;\begin{cases}&#10;r=\sqrt{a^2+b^2}\\&#10;\theta =tan^{-1}\left( \frac{b}{a} \right)&#10;\end{cases}\qquad r[cos(\theta )+i\ sin(\theta )]\\\\&#10;-------------------------------\\\\

\bf r=\sqrt{(-6)^2+(6\sqrt{3})^2}\implies r=\sqrt{36+(6^2\cdot 3)}\implies r=\sqrt{144}&#10;\\\\\\&#10;r=12\leftarrow &#10;\\\\\\&#10;\theta =tan^{-1}\left( \frac{6\sqrt{3}}{-6} \right)\implies \theta =tan^{-1}\left( -\sqrt{3}\right)\implies \theta =&#10;\begin{cases}&#10;\frac{2\pi }{3}\leftarrow \\&#10;\frac{5\pi }{3}&#10;\end{cases}

now, notice, there are two valid angles for such a tangent, however, if we look at the complex pair, the "a" is negative and the "b" is positive, that means, "x" is negative and "y" is positive, and that only occurs in the 2nd quadrant, so the angle is in the second quadrant, not on the fourth quadrant.

thus         \bf 12\left[cos\left( \frac{2\pi }{3} \right) +i\ sin\left( \frac{2\pi }{3} \right) \right]
