5x+17 = 8x-31
48 = 3x
x = 48/3
x = 16
RS = 5x + 17 = 5*16 +17 = 80 +17 = 97
RS = 97
hope helped
1/16 per minute
1/16 = x/60
60/16=3.75
He would be able to eat around 3 pizzas per minute
Hence making B the correct answer
In paraller connection you can calculate the equivlant resistqnce from the relation :
1/R(equi) = 1/R1 + 1/R2 + 1/R3
1/R(equi) = 1/20 +1/20 + 1/10
1/R(equi) = 0.05+0.05+0.1 = 0.2
so, R(equi) = 5 ohms
Answer:
20 passengers at $960 each
Step-by-step explanation:
Assuming at least 20 people sign up for the cruise, determine how many passengers will result in the maximum revenue for the owner of the yacht.
(a) Find a function R giving the revenue per day realized from the charter.
R(x) =
(b) What is the revenue per day if 48 people sign up for the cruise?
$
(c) What is the revenue per day if 78 people sign up for the cruise?
$
revenue (R) = (20+x)(960-8x)
= 19200 - 160x + 960x -8 x^2
dR/dx = -160 + 960 - 16x = 0 for a max of R
16x = 800
x = 50
