Carlotta is making cookies for a party. Her recipe calls for 2 eggs and 1 3/4 cups of flour. If Carlotta makes a large batch of
yanalaym [24]
Well we know that every 2 eggs requir 1 and 3/4 of flour so the easiest thing to do here (for me at least) is to round the fraction to the nearest whole number which in this case will be 1. Now that that's done we can say every 2 eggs calls for 2 cups of flour. Now all you need to do is multiply 2 by 9 to get 18 then put that in fraction form it'll be 17 and 3/4 cups of flour. I hope this helps!

in ABC the measure of angle A is 2x+3 the measure of angle B is 4x+2 the measure of angle C is 2x-1 what are the measures of the
Virty [35]


IN A triangle, sum of all angles = 180 degrees

2x + 3 + 4x+2 + 2x -1 = 180

8x +4  = 180

8x = 176

x = 176 /8 = 22 degrees

the angles are A = 2(22)+3 = 44+3 = 47 DEGREES

B = 4(22)+2 = 88 + 2 = 90 DEGREES

C = 2(22) -1 44-1 = 43 DEGREES

PRECALC QUESTION! Convert the polar representation of this complex number into its standard form: z = 2(cos 11pi/6+ i sin 11pi/6
Tanzania [10]
\bf z=2\left[ cos\left( \frac{11\pi }{6} \right) + i\ sin\left( \frac{11\pi }{6} \right) \right]\qquad 
\begin{cases}
r=2\\
\theta=\frac{11\pi }{6}\\
-----\\
a=x=rcos(\theta)\\
b=y=rsin(\theta)
\end{cases}\implies a+bi
\\\\\\
2cos\left( \frac{11\pi }{6} \right)+2sin\left( \frac{11\pi }{6} \right)\ i\implies 2\cdot \cfrac{\sqrt{3}}{2}+2\cdot \cfrac{-1}{2}\ i\implies \sqrt{3}-1i
\\\\\\
\boxed{\sqrt{3}-i}
