Answer:
28
Step-by-step explanation:
Use the pythagorean theorem and solve for a:
a² + b² = c²
a² + 21² = 35²
a² + 441 = 1225
a² = 784
a = 28
So, the missing length is 28.
3 consecutive even integers.....x, x + 2, and x + 4
x + x + 2 + x + 4 = 270
3x + 6 = 270
3x = 270 - 6
3x = 264
x = 264/3
x = 88
x + 2 = 88 + 2 = 90
x + 4 = 88 + 4 = 92 <=== the biggest integer
um, that statement is correct. is that the question?
Answer:
The formula for this would be 
Since we need to multiply the fraction against the amount of batches, to get the final result of cups of flours. (It only makes sense!)
8/3 is the correct answer
2 2/3 is the mixed fraction
C. 25% decrease because
20-15/ 20 x 100 = 25% decrease
