5×3=15 (total circles)
15÷6 = 2.5 ( circles each students get )
Answer:
standard form is f(x) = ax^2 + bx + c
sample equation: f(x) = 5x^2 + 10x + 5. a=5, b=10, c=5
Step-by-step explanation:
a, b, and c are real numbers in the standard form equation. if a>0 the parabola opens upwards, if a<0 parabola opens downwards
6)
91 is a composite number because it's divisible by 7 and 13
7)
477 is divisible by 3 and 9, since the sum of its digits (18) is divisible by 3 and 9 ( or the sum is a multiple of 3 and 9) .Not divisible by 6
8)
348:is divisible by 4 because the last 2 digits (48) are a multiple of 4
348:is NOT divisible by 5 because the last digit is neither 5 nor 0
348:is divisible by 6 because it's divisible by 2 and also by 3
9)
23624 is divisible by 8 because te last 3 digits (624) are divisible y 8
(624/8 =78)
None of the others are divisible by 8
10) A number is divisible by 6 IF IT'S DIVISIBLE BY 2 AND BY 3:
213 NO
468 is divisible by 2 since the last digit is divisible by 2. It's also divisible by
3 since the sum of its digits [18] is divisible by 3, hence 468 is divisible by 6
621 it's divisible by 3 but NOT by 2, then it's not divisible by 6
Answer:
x = 60
Step-by-step explanation:
