Answer:
$6,563
Step-by-step explanation:
First, place the numbers into the formula A=P(1+r)^n and make the percent into a decimal:
A= 2,583(1+0.027)^35
Solve the equation and you get your answer:
6,562.811525
Round to the nearest whole number:
$6,563
Answer: 56.548
Step-by-step explanation: Circumfrance = (radius x pi) x2
The absolute value of 3 and the absolute value of negative 3. they have the same distance from 0
X + y = 20 --> eqn 1
The second equation would be the mass balance shown below:
(x)(0.40) + y(0.70) = 20(0.52) --> eqn 2
Rearranging eqn 1,x = 20 - ySubstitute this to eqn 2:
(20 - y)(0.40) + y(0.70) = 20(0.52)Solve for y,y = 8 grams Finally, solve for x.x = 20 - 8 = 12 grams
Therefore, Serena needs 12 grams of the 40% solution and 8 grams of the 70% solution.
