Answer:
23
Step-by-step explanation:
8 kg * 28 per kg = Rs. 224
Profit = Rs. 40
CP = SP - Profit
224 - 40
184
184 / 8
23
Answer:
22x+11 is your answer
Step-by-step explanation:
(2x+1)(x+8) - (x-3)(2x+1)
(2x+1)(x+8-x+3)
(2x+1)(11)
=22x+11
81
(-9)(-9) is 81
Multiplying two negatives gives a positive
Answer:
The mean is 4.88 hours / day
Step-by-step explanation:
To calculate the mean we just add the values and divide by the number of items (in this case we add the hours and divide by the number of days)
so the equation would be

Answer:
He showed that f(n) ÷ f(n - 1) was a constant ratio.
Given that Jake has proved that a function f(x) is a geometric sequence.
GEOMETRIC SEQUENCE: A geometric sequence is a sequence of numbers where each term is found by multiplying the preceding term by a constant called the common ratio, r.
So, in Jame's proof, he showed that each term is multiplied by a constant to get the next term.
That is, if 'c' is the constant that was used in the proof, then we must have
This implies that
Therefore, he showed that f(n) ÷ f(n - 1) was a constant ratio.
