$18 divided by $0.75 =24
She sold 24 cups of lemonade, and your equation looks like this:
$18 ÷ $0.75 = 24
Your answer is 2/3 hope this helps
Answer:
45%
Step-by-step explanation:
Simply divide your partial amount (18 in this case) by your total (40), and you then multiply your answer from 18/40= .45 by 100, and you get 45. This is 45%
The question tackles about arithmetic sequence.
Arithmetic sequence has the formula:
an<span> = a</span>1<span> + (n – 1)d.
</span>where
an = number at nth term
a1 = 1st term
n = number of terms
d = common difference.
an<span> = a</span>1<span> + (n – 1)d.
</span>a1 = -10
d = -2
n = 10
a2 = -10 + (2-1) -2
a2 = -12
if we continue until a10, the sequence will be
-10, -12, -14, -16, -18, -20, -22, -24, -26, -30
The vertex form: y = a(x - h)² + k
y = ax² + bx + c then h = -b/2a and k = f(h).
y = x² - 12x + 8
a = 1; b = -12; c = 8
h = -(-12)/(2·1) = 12/2 = 6
k = f(6) = 6² - 12·6 + 8 = 36 - 72 + 8 = -28
Answer: y = (x - 6)² - 28.
