Sales in the printing business have doubled for James in each of the last three months. During the last month, he made a profit of $520. If the pattern continues, what will be his three month total profit at the end of the next three months?
Answers
x=520*2^n
n is the current month
We are looking for the sum of next 3 months, so n+1, n+2 and n+3.
520*2^(n+1)+520*2^(n+2)+520*2^(n+3)=520*4+520*8+520*16=2080+4160+8320=14560

Step-by-step explanation:
i think it would be 14 bananas if u take 3 divided by 42
hope that is right.
he rides for 7 min and waits in line for 20 min, if he was to wait in line for 60 min then he would ride for 21 min, if you divide 20/60 then you'll get 3. Multiply the 7 with that 3 and you'll get "21".

Answer:
$1,920
Step-by-step explanation:
We first want to find out how much money she earns in a week which we can find by multiplying 40 by 12. Now we want to multiply 480 by 4. Hence the answer 1920
Answer:
$1920
Step-by-step explanation:
It would be $1920 because if you do 40*12, it would be 480. So that's 480 a week. Since the question is asking for 4 weeks, you would then multiply it by 4, making it $1920.

(1) To solve for h, we manipulate the variable such that it becomes,
h = √(v / 8)
Substituting the given,
h = √ (96 / 8) = √12 ft
(2) To solve for P in this problem, we raise both sides of the equation to exponent 2,
P = I²R
Substituting,
P = (2.5 amps)² x (16 ohms)
P = 100 watts
Final answer:
To find the distance fallen, substitute the given velocity into the equation and solve for h. To find the power being used, substitute the given current and resistance into the equation and solve for P.
Explanation:
1. To find the distance that an object has fallen if its velocity is 96 feet per second, we need to use the given equation v = 8h^(1/2). We'll substitute 96 for v in the equation and solve for h:
96 = 8h^(1/2)
To isolate h, we'll divide both sides of the equation by 8:
12 = h^(1/2)
To get rid of the exponent, we'll square both sides of the equation:
144 = h
Therefore, the object has fallen a distance of 144 feet.
2. The equation IR^(1/2) = √P represents the relationship between current (I), power (P), and resistance (R). We're given that I = 2.5 amps and R = 16 ohms. We'll substitute these values into the equation and solve for P:
(2.5)(16)^(1/2) = √P
(2.5)(4) = √P
10 = √P
To isolate P, we'll square both sides of the equation:
100 = P
Therefore, the appliance is using 100 watts of power.
