Answer:

$9.86

Step-by-step explanation:

Frist you read the problem and you see that she pays $1.89 for one drink

so you write down $1.89

then 3 cookies for $0.99 so you multiply $0.99 by 3 and you get $2.97

so you write down $2.97

next 2 slices of pizza for $2.50 so you multiply 2 by $2.50 and you get $5.00

so you write that down

lastly you and the answers you wrote down and you get $9.86

Maya payed $9.86 for her order.

Help!! Which of the following best represents Z1 • Z2 select all that apply
AURORKA [14]

z_1=\sqrt{3}\left(cos\:\frac{\pi }{4}+i\:sin\:\frac{\pi }{4}\right)

z_2=\sqrt{6}\left(cos\:\frac{3\pi \:}{4}+i\:sin\:\frac{3\pi \:}{4}\right)

\cos \left(\frac{\pi }{4}\right)=\frac{\sqrt{2}}{2}

\sin \left(\frac{\pi }{4}\right)=\frac{\sqrt{2}}{2}

\cos \left(\frac{3\pi }{4}\right)=-\frac{\sqrt{2}}{2}

\sin \left(\frac{3\pi }{4}\right)=\frac{\sqrt{2}}{2}\\

Z_1*Z_2=\sqrt{3}\left(cos\:\frac{\pi }{4}+i\:sin\:\frac{\pi }{4}\right)\cdot \sqrt{6}\left(cos\:\frac{3\pi \:}{4}+i\:sin\:\frac{3\pi \:}{4}\right)

=\sqrt{3}\left(\frac{\sqrt{2}}{2}+\:i\frac{\sqrt{2}}{2}\right)\cdot \sqrt{6}\left(\frac{-\sqrt{2}}{2}+\:i\frac{\sqrt{2}}{2}\right)

On simplifying, we get

Z_1* Z_2 =-3\sqrt{2}

<h2>Therefore, correct option is  1st option.</h2>

I need help solving problem 11.
Lunna [17]
Since triangle ABC is isosceles, then angles 1 and 9 are congruent.

4x + 3 = 9x - 47

-5x = -50

x = 10

m<1 = 4x + 3 = 40 + 3 = 43

m<1 = m<9 = 43

Triangle DBE is equilateral, so it is also equiangular.

m< 4 = m<5 = m<6 =60

Angles 3 and 8 are supplementary to congruent angles that measure 60 deg, so 180 - 60 = 120, so

m<3 = m<8 = 120

For angles 2 and 7, use the sum of the measures of the angles of a triangle is 180 deg.

m<1 + m<2 + m<3 = 180

43 + m<2 + 120 = 180

m<2 + 163 = 180

m<2 = 17

m<2 = m<7 = 17
