L+S=8, L=8-S
500L+200S=2200, using L from above in this equation gives you:
500(8-S)+200S=2200
4000-500S+200S=2200
4000-300S=2200
-300S=-1800
S=6, and since L=8-S:
L=2
So Rita bought 2 large packets and 6 small packets.
$0.50/ (1/4 pound)= $2.00/pound.
The final answer is $2.00 per pound~
Answer:
25 (price of 1 mug)
40 ( price of 1 tumbler)
Step-by-step explanation:
15 x 17 = 255
880 - 255 = 625
625 ÷ (17+8) = 25 (price of 1 mug)
25+15 = 40 ( price of 1 tumbler)
Answer:
? what??!?!?
Step-by-step explanation:
THE ANSWER IS 700, I EDITED AFTER I KNEW WHAT THIS MEANT, THE ANSWER IS 700 <3
First find the the value of t where the curve intersects the Y-axis. This is when x = 0.
x = t^2 - 2t = 0 = t(t - 2)
So t= 0 and t = 2
dA = (0 - x)*dy .... Since the curve has negative x in this region
y = SQRT(t) and dy = [(1/2)/SQRT(t)]dt
dA = [2t - t^2][(1/2)/SQRT(t)]dt
dA = [t^(1/2) - (1/2)t^(3/2)]dt
Integrate to get: A = (2/3)t^(3/2) - (1/5)t^(5/2)
Now evaluate from t= 0 to t = 2.
Area = [(2/3)2^(3/2) - (1/5)2^(5/2)] - [0]

Area = SQRT(2)[4/3 - 4/5]
</span><span>
Area = SQRT(2)[8/15) = 0.754
