well, since we know that there are 180° in π radians, how many degrees will it be in 345°?

\begin{array}{ccll} degrees&radians\\ \cline{1-2} 180&\pi \\ 345&x \end{array}\implies \cfrac{180}{345}~~ = ~~\cfrac{\pi }{x}\implies \cfrac{12}{23}~~ = ~~\cfrac{\pi }{x} \\\\\\ 12x=23\pi \implies x=\cfrac{23\pi }{12}

Maurinko [17]

Answer:

Kaitlin's answer is wrong because she is supposed to by dividing. When trying to get rid of a number from a variable you have to divide the number by itself and whatever you do to one side you have to do to the other side

so you would do 5/5 - cancels out

15/5=3

y=3

Let v = 3i + 2j and w = 2i + 3j. Sketch v, w, v + w, 2w, and v − w in the plane
Nimfa-mama [501]

Answer:

Step-by-step explanation:

In the argand plane for plotting points of complex numbers we take i coefficient as x and j coefficient as y and plot as we plot regular points on the graph.

v=3i+2j

Point is (3,2) A

w =2i+3j , Point is (2,3) B

v+w = 5i +5j Point is (5,5) C

2w = 4i+6j , point is (4,6)

v-w = i-j Point (1,-1)

Please find enclosed the above points plotted on the graph.

Several trays of danishes are ordered for a breakfast about 35% or cream filled there are four trays of 18 danishes on each tray
zvonat [6]

There are <em><u>25 danishes </u></em>contain cream filling

<h3>Further explanation</h3>

The percent is a number that shows a comparison of the number 100 or can be called per hundred (symbol%)  

Formula used:  

\large{\boxed{\bold{Percentage\:=\:\frac{Total\:Section}{Total\:Amount}\:\times\:100\percent}}}

Fractions either proper or mixed (consisting of numerators and denominators) or decimal forms

The percentage can be expressed as a decimal by moving the decimal point two places to the left

One way to convert proper fractions to percent forms is by multiplying the fraction by 100% or By changing the denominator to 100 because percent is the percent. Multiply the numerator and denominator with the same number

35% from Several trays of danishes are filled with cream

There are four (4) trays

18 danishes on each tray

  • Total danishes :

\displaystyle =18\times 4\\\\=72\:danishes

  • 35% are filled with cream

\displaystyle = \frac{35}{100}\times 72\\\\=\boxed{\bold{25.2}}

Round up to<em><u> </u></em><em><u>25 danishes</u></em>
