Answer and Step-by-step explanation:
Let
Number of chocolate chip cookies = x
Number of oatmeal brownie cookies = y
Bake chocolate chip cookies up to 20 dozen = x≤ 20
Bake oatmeal brownies up to 40 dozen= y≤40
Total cookies = x + y ≤ 50
Number of oatmeal brownie will be no more than three times the number of chocolate chip= y≤3x
From the inequality:
X + y=50
y = 3x
By putting the value of y, we get
x + 3x = 50
4x = 50
X = 12.5
By putting the value of x=12.5 in equation y = 3x, we get
Y = 3(12.5)
= 37.5
Craig should make 12.5 dozen chocolate chip and 37.5 dozen oatmeal brownies in order to make more money.
So since the formula for the sum of a polygon's interior angles is (n-2)180, just make that equal to 2520 and solve for n, which is the number of sides.
STEPS:
1) (n-2)180 = 2520
2) n-2 = 2520/180
3) n-2 = 14
4) n = 16
So the polygon must have 16 sides
Answer:
The average spent per person would be about $27.63
Step-by-step explanation:
$63.25 + 15(3)
Step 1 - Multiply 15 (the tip) times 3 (amount of friends) which equals 45% (or $19.63)
Step 2 - Add 63.25 and 19.63 which equals 82.88.
$63.25 + $19.63 = $82.88
The average bill in total would be about $82.88
Step 3 - Divide the total by 3(each person)
82.88 ÷ 3 = 27.63
The average spent per person including the tip would be about $27.63.

How much further can Anna see to the horizon?
Answer:
36 cm
Step-by-step explanation:
The sum of the perimeters of three lateral faces will count each "lateral" edge twice and the base edges once. Adding the base perimeter to that product will count every edge twice, so the total of all edge lengths is ...
(3(18.5 cm) +16.5 cm)/2 = 72 cm/2 = 36 cm . . . . sum of all edge lengths
