I'm not sure what you're supposed to round to, but since this is money, I would suggest including the dollar sign in front of the answers and including round to the hundredth's decimal place. Otherwise, you're answers are correct.
Answer:
z
point z is the correct answer.
Step-by-step explanation:
y = (4, 0.5)
w = (4, -0.5)
x= (4, -1.5)
Answer:
my brother said it was
Step-by-step explanation:
1400.053...
Answer:
i) 3.38%
ii) 23846 pesos
Step-by-step explanation:
The formula for Simple Interest =
Principal × Rate × Time
Simple Interest is calculated as:
Amount(after t years) - Principal(initial amount
From the question,
Amount = 2480000 pesos
Principal = 2323000 pesos
Simple Interest = (2480000 - 2323000)pesos
= 157000 pesos
i. What is the simple interest rate the electronics store is charging if he ends up paying it 2480000 pesos in total?
This means we are to find r, hence:
Simple Interest = Principal × Rate × Time
Time = 2 years
157,000= 2323000 × R × 2
R = 157,000/2323000 × 2
R = 157,000/4646000
R = 0.03379250968
Simple Interest rate = 0.03379250968
Converting to percentage
= 3.379250968%
≈ Approximately 3.38%
ii. How much is weekly payment to the electronics store? Round your answer to the nearest Peso.
We are told in the question that:
Fernando pays the electronic store in weekly installments over two years.
52 weeks = 1 year
Hences
2 years = 52 × 2 = 104 weeks
Weekly payments = 2480000 pesos/104 weeks
= 23846.1538462 pesos
Approximately to the nearest peso = 23846 pesos
<u>General method</u><u>:</u>
Given numbers are 1.3 bar and 1.4 bar
- 1.3 bar = 1.333...
- 1.4 bar = 1.444...
Two rational numbers between them
= 1.3222... and 1.43333...
<u>Mean Method</u><u>:</u>
Let X = 1.333... → → →eqn(i)
since the periodicity is 1 then multiply eqn(i) with 10
⇛10×X = 1.333...×10
⇛10X = 13.333... → → →eqn(ii)
Subtract eqn(ii)-eqn(i)
10X = 13.333...
X = 1.333...

⇛9X = 12
⇛X = 12/9
⇛X = 4/3
and
Let X = 1.444... → → →eqn(i)
since the periodicity is 1 then multiply eqn(i) with 10
⇛10×X = 1.444...×10
⇛10X = 14.444...→ → →eqn(ii)
Subtract eqn(ii)-eqn(i)
10X = 14.444...
X = 1.444...

____________
9X = 13.000...
____________
⇛9X = 13
⇛X = 13/9
Now we have 12/9 and 13/9
The rational number between them by mean method (a+b)/2
⇛{(12/9)+(13/9)}/2
⇛(25/9)/2
⇛25/18
and Second rational number
⇛{(12/9)+(25/18)}/2
⇛{(24+25)/18}/2
⇛(49/18)/2
⇛49/36
<u>Answer</u><u>:</u> The two rational numbers between them are 25/18 and 49/36.
