Answer:
You are looking for a geometric series equation. The first term of the sequence is 6 and the common ratio is 4 hence the equation is 6(4)^n-1 where n is the number of generations.
Step-by-step explanation:
So, first let's refill the barrel to the top:
37.5 + 7*2.5 = 55
Now that it's full again, let's divide the total amount by the rate of water loss:
55/2.5 = 22
It will take 22 minutes to completely empty the rain barrel
Y = x - 28/5. The slope here is 1. A perpendicular line will have a negative reciprocal slope. So our perpendicular line will have a slope of -1.
slope = (y2 - y1) / (x2 - x1)
(k,2)....x1 = k and y1 = 2
(7,0)...x2 = 7 and y2 = 0
sub
slope = (0 - 2) / (7 - k)
slope = -2 / ?......now if we want the slope to be -1..that means the number where the question mark is has to be 2....for that to happen, k has to be 5...because 7 - 5 = 2.
so ur answer is : k = 5
Answer:
192
Step-by-step explanation:
Well, well, it takes four 1/4's to equal 1. So, they can make 4 burgers with 1 pound of meat. So, simply multiply 48 times 4 to get your answer.
Answer:
$3.50/donut
Step-by-step explanation:
Since Rosena bought an 8-pack of donuts for $28.00, we can say that the price of $28.00 corresponds with this pack.
The unit rate represents the price per donut, assuming a constant proportion.
The pack that Rosena bought contains 8 donuts. Therefore, to find the price of one donut, divide the price that corresponds with the 8-donut pack by 8, because 
.
The price of the 8-pack of donuts was 
. Diving by 8, we have:
Therefore, the unit rate for the donuts is $3.50/donut.
