Answer:
Don caught 3.6 kg and Dan caught 0.6 kg.
Step-by-step explanation:
Set up a system of equations:
Don's fish is the variable a and Dan's fish is the variable b.
a + b = 4.2 (1)
a=6b (2)
We can substitute a in the first equation using the second equation, so:
6b + b = 4.2
7b = 4.2
b = 0.6 kg
Dan caught 0.6 kg. Then, we can use equation 2 to find how much Don caught.
a = 6 x 0.6
a = 3.6
Don caught 3.6 kg.
Answer:
1. = x^2 -5x+6
Step-by-step explanation:
2. = 2x^2 +5x+3
3. =2x^2 +(x-1) +((x)/x^2 -x+6)
Answer:
No it is not.
Step-by-step explanation:
Reason.
For geometric: common ratio r should be equal
r = T2/T1 = T3/T2 but is not true here as -6/-14 is not equal to 2/-6
Answer:
Step-by-step explanation:
A new car is purchased for $25,000 over time its value depreciates by one half every 5 years. How long, to the nearest tenth of a year, would it take for the value of the car to be $5,000?
The formula now given as:
F = P(1 - r) ^t
F = Future value = $5000
P = Present value = $25000
r = Depreciation rate = 1/2 every 5 years
Hence:
5000 = 25000( 1 - ) ^t
