Answer:
Martha earns $65.6 over the weekend.
Step-by-step explanation:
Brownies sold by Martha on Saturday = 60
Cookies sold by Martha on Saturday = 42
Brownies sold by Martha on Sunday = 28
Cookies sold by Martha on Sunday = 54
Total brownies sold by Martha over the weekend = 
Total cookies sold by Martha over the weekend = 
Cost of a brownie = $0.20
Cost of a cookie = $0.50
Total cost of brownies sold over the weekend = 
Total cost of cookies sold over the weekend = 
∴ Total money Martha earned over the weekend = 
(Answer)

S=6
V(6)=6^3/6=6^2=36
Answer:
4,500,000 population in 1950
Step-by-step explanation:
the equation is 4p + 1,000,000 = 19,800,000
Respuesta:
A.) BA = 12 m
Explicación paso a paso:
Usando triángulos similares:
BA / AC = DE / EC
BA = x; AC = 20; DE = 3; EC = 5
POR ESO ; TENEMOS :
x / 20 = 3/5
Multiplicar en cruz:
5 * x = 20 * 3
5 veces = 60
5x / 5 = 60/5
x = 12
Answer:
C(p) = 4,96 (in thousands of dollars)
l = 2980 $ invest in labor
k = 2980 $ invest in equipment
Step-by-step explanation:
Information we have:
Monthly output P = 450*l*k ⇒ k = P/450*l
But the production need to be 4000
Then k = 4000/450*l
Cost of production = l * k (in thousands of dollars)
C(l) = l + 4000/450*l
Taking derivatives (both members of the equation)
C´(l) = 1 - 400 /45*l² ⇒ C´(l) = 0 ⇒ 1 - 400/45l² = 0
45*l² - 400 = 0 ⇒ l² = 400/45
l = 2.98 (in thousands of dollars)
l = 2980 $ And
k = 400/45*l ⇒ k 400/45*2.98
k = 2.98 (in thousands of dollars)
C(p) = l + k
C(p) = 2980 + 2980
C(p) = 5960 $
