Answer:
225 m²
Step-by-step explanation:
If W is the width of the rectangle, and L is the length, then:
60 = 2W + 2L
A = WL
Use the first equation to solve for one of the variables:
30 = W + L
L = 30 − W
Substitute into the second equation:
A = W (30 − W)
A = 30W − W²
This is a parabola, so we can find the vertex using the formula x = -b/(2a).
W = -30 / (2 × -1)
W = 15
Or, we can use calculus:
dA/dW = 30 − 2W
0 = 30 − 2W
W = 15
Solving for L:
L = 30 − W
L = 15
So the maximum area is:
A = WL
A = (15)(15)
A = 225
Answer: 5
Step-by-step explanation: The answer is 5 since "median" means the middle. If you count the numbers you get 13. Since 13 isnt even you count half of 12 which is 6 then count 6 on both sides, youll end up with 5 not fitting into the group. Im not the best at explaining so im sorry! Hope this helps!
Answer:
Your answer will be C. $5.79.
Step-by-step explanation:
To get this answer, you have to take the original price (3.99) and multiply it by the mark up (45%)
3.99x0.45=1.79
Then, you add 3.99 and 1.79 to get your final answer.
3.99 + 1.79 = 5.78
The answer is off by one penny, BUT, it's tricky to get it exact when you're working with decimals and percentages.
