I would just try to identify the pattern. First, for the cups column, if the amount increases by 5 each time, then the missing box must be 5 less than 10 or 5
The, for the servings column, you can test to find the pattern. If you were to guess the pattern is 3, when you check, you would see that the boxes are 6 and 9 because then it increases by 3 each time
Hope this helps
30/100.
To get to this, you need to change the denominator to 100. 10 x 10 = 100 so whatever you do to the denominator, you do to the numerator. 3 x 10 = 30 so your answer would be 30/100.
216x-6x=1
210x=1
x= 1/210
x= 0.00476
Arc length = radius * central angle (radians)
central angle (radians)= arc length / radius
central angle (radians)= 60 / 15
central angle (radians)= 4 radians
sector area =(central angle / 2) * radius^2
sector area = (4 / 2) * 225
sector area = 450
