To find the perimeter, we want to add up all of the sides. You got all of the sides that were labelled, but missed the long side on top. Also, the answer should be a mixed number, not an improper fraction.

We can find the long side by adding up the variables that were already given:

3x-1 + 3x-1 + 3x-1=9x-3

Now, we can set up the equation of perimeter to solve for x:

9x-3 + x + 3x-1 + x + 3x-1 + x + 3x-1 + x = 1038
22x - 6 = 1038
22x = 1032
x=1032/22
x=516/11
x=46 10/11

Convert each measure into radians

mars1129 [50]

Answer: -240 = -4π / 3, 60 = π / 3, 270 = 3π / 2, 945 = 21π / 4, -30 = -π / 60, 195 = 13π / 12

Step-by-step explanation:

The formula for converting Degrees into Radians is Degrees * (π / 180) = Radians.

For -240, we have -240 * (π / 180) = -240π / 180 and simplifying gives us -4π / 3

60: 60 * (π / 180) = 60π / 180 = π/3

270: 270 * (π / 180) = 270π / 180 = 3π / 2

945: 945 * (π / 180) = 945π / 180 = 21π / 4

-30: -30 * (π / 180) = -30π / 180 = π / 60

195: 195 * (π / 180) = 195π / 180 = 13π / 12

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 25 danishes 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
