Gilbert is baking cookies and brownies for a bake sale. It costs him $3 for every batch of cookies he makes and $4 for every bat
Brilliant_brown [7]
Let c=the number of batches for the cookies; b=that for the brownies.
If $P=the profit, then
maximize P=5c+4.5b, subject to the constaints:
3c+4b<=100 (cost)
2c+b<=45 (time)
b,c >=0
The simplest way to find the suitable b & c is
to solve
3c+4b=100
2c+b=45
for b & c
The result is b=13 & c=16
=>
max. p=5(16)+4.5(13)=$138.5

Hope this helps :)

Find the area of the figure to the nearest thousandth
CaHeK987 [17]

Answer:

236.715\:\mathrm{ft^2}

Step-by-step explanation:

The area of the figure consists of a rectangle and two half-circles.

Area of rectangle: 15\cdot 4=60

Area of two half-circles: 2\cdot \frac{1}{2}\cdot 7.5^2\cdot \pi=176.714586764

Thus, the total area of the figure is

60+ 176.714586764\approx \boxed{236.715}
