$90 because you take the discounted price then divide it by .40 (40%)
Answer:
16 lb of fresh coffee.
Step-by-step explanation:
Let x pound be the amount of fresh coffee needed.
100 - 12 = 88% is equivalent to 14 2/25 of roasted coffee.
By proportion x = 14 2/25 / 88/100
= 352 / 25 * 100/88
= 35200 / 25 * 88
= 16 lb (answer).
Answer:
Question 1: g = 6
Question 2: v = 84
Question 3: y = 60
Question 4: w = 496
Question 5: Kyle had $400 to begin with.
Step-by-step explanation:
Question 1 explanation: 12g = 72 ⇒ g = 
= 6
Question 2 explanation: 
= 21 ⇒ v = 21 * 4 = 84
Question 3 explanation: 
y = 10 ⇒ 6 * y = 10 * 6 ⇒ y = 60
Question 4 explanation: w + 376 = 872 ⇒ w = 872 - 376 = 496
Question 5 explanation: K - 85 = 315 ⇒ K = 315 + 85 = 400, so Kyle had $400 originally in his account.
Answer:
(x - 8)^2 + (y - 4)^2 = 16.
Step-by-step explanation:
The standard form can be written as:
(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the center and r = the radius.
So here we have a = 8, b = 4 and r = 4.
(x - 8)^2 + (y - 4)^2 = 4^2
(x - 8)^2 + (y - 4)^2 = 16.
