A car loan worth 800,000 pesos is to be settled by making equal monthly payments at 7% interest compounded monthly for 5 years. How much is the monthly payment? How much is the outstanding balance after 2 years?
The monthly payment for the car loan is approximately 16,216.38 pesos. The outstanding balance after 2 years is approximately 650,577.85 pesos.
To find the monthly payment for the car loan, we can use the formula for the monthly payment on a loan:
P = (r * PV) / (1 - (1 + r)^(-n))
Where:
P is the monthly payment
r is the monthly interest rate
PV is the loan amount (present value)
n is the total number of payments
In this case, the loan amount PV is 800,000 pesos, the monthly interest rate r is 7% / 12 (since the interest is compounded monthly), and the total number of payments n is 5 years * 12 months/year = 60 months.
Substituting these values into the formula, we have:
P = (0.07/12 * 800,000) / (1 - (1 + 0.07/12)^(-60))
Calculating this expression, we find that P ≈ 16,216.38 pesos.
So, the monthly payment for the car loan is approximately 16,216.38 pesos.
To find the outstanding balance after 2 years, we need to calculate the remaining balance after making monthly payments for 2 years. We can use the formula for the remaining balance on a loan:
Remaining Balance = PV * (1 + r)^n - P * ((1 + r)^n - 1) / r
Where:
PV is the loan amount (present value)
r is the monthly interest rate
n is the number of payments made
Substituting the given values into the formula, we have:
Remaining Balance = 800,000 * (1 + 0.07/12)^24 - 16,216.38 * ((1 + 0.07/12)^24 - 1) / (0.07/12)
Calculating this expression, we find that the outstanding balance after 2 years is approximately 650,577.85 pesos.
So, the outstanding balance after 2 years is approximately 650,577.85 pesos.

half year at 40 percent of interest compounded
quarterly?
The amount of the sum Rs 1200 for one and a half year at 40 percent of interest compounded quarterly is Rs 1893.09.
The amount of the sum Rs 1200 for one and a half year at 40 percent of interest compounded quarterly can be calculated as follows:
Given, Principal = Rs 1200Time = 1.5 yearsInterest rate = 40% per annum, compounded quarterly
Let r be the quarterly rate of interest. Then we can convert the annual interest rate to quarterly interest rate using the following formula: \text{Annual interest rate} = (1 + \text{Quarterly rate})^4 - 1$$
Substituting the values, we get:0.40 = (1 + r)^4 - 1 Solving for r, we get:r = 0.095 or 9.5% per quarter
Now, we can use the formula for the amount of money after time t, compounded quarterly: $A = P \left( 1 + \frac{r}{4} \right)^{4t}
Substituting the values, we get:A = Rs 1200 x $\left(1 + \frac{0.095}{4} \right)^{4 \times 1.5}= Rs 1893.09
Therefore, the amount of the sum Rs 1200 for one and a half year at 40 percent of interest compounded quarterly is Rs 1893.09.

1) ABCD is a trapezium. AB ║ CD
∠ADC + ∠DAB = 180° { Co interior angles}
110° + ∠DAB = 180
∠DAB = 180 -110
∠DAB = 70°
2) Sum of all angles of trapezium = 360°
∠A + ∠B + ∠DCB + ∠D = 360
70° + 50° + ∠DCB + 110° = 360
230 + ∠DCB = 360
∠DCB = 360 - 230
∠DCB = 130°
3) For finding the height, use Pythagorean theorem
height² + base² = hypotenuse²
height² + 6² = 10²
height² + 36 =100
height² = 100 - 36
height² = 64
height = √64
height = 8 m
4) a = AB = x m
b = 9 m
h = height = 8 m
Area of trapezium = 120 m²
\(\frac{(a+b)*h}{2}\\\\\) = 120

a spinner is spun twice with 4 equal sections colored purple, orange, green, and blue. what is the p(spinning two greens)?
The probability of spinning two greens on the spinner is 1/16.
To find the probability of spinning two greens on the spinner, we need to determine the probability of spinning a green on the first spin and then the probability of spinning another green on the second spin. Since there are 4 equal sections on the spinner and one of them is green, the probability of spinning a green on the first spin is 1/4.
After the first spin, assuming the spinner is put back to its original state, the probabilities for each section remain the same. Therefore, the probability of spinning a green on the second spin is also 1/4.
To find the probability of both events happening (spinning two greens), we multiply the probabilities together:
P(spinning two greens) = P(green on first spin) * P(green on second spin)
= (1/4) * (1/4)
= 1/16
Therefore, the probability of spinning two greens on the spinner is 1/16.

based on the vsepr approach, which dot structure should have the smallest xax bond angle?
Based on the VSEPR approach, the dot structure with the smallest XAX bond angle would be the one with the greatest number of lone pairs on the central atom.
This is because lone pairs occupy more space than bonded atoms and cause greater repulsion, leading to a smaller bond angle. Therefore, the dot structure with the smallest XAX bond angle would be the one with the most lone pairs on the central atom.
In general, lone pairs do indeed exert greater repulsion compared to bonded pairs because they occupy more space around the central atom and are closer to the central atom. However, it is not always true that the dot structure with the greatest number of lone pairs on the central atom will have the smallest XAX (bonded pair-bonded pair) bond angle.
The bond angles in a molecule are also influenced by the number of bonded atoms around the central atom and their positions in three-dimensional space.
For example, in a molecule with three bonded atoms and one lone pair (AX3E), the lone pair will be positioned in a way that minimizes repulsion with the bonded atoms, resulting in a larger bond angle compared to a molecule with only bonded atoms (AX3). On the other hand, in a molecule with two bonded atoms and two lone pairs (AX2E2), the bond angle may be smaller due to the repulsion between two lone pairs.
So, while it is true that lone pairs generally cause greater repulsion and can affect the bond angles in a molecule, it is not solely dependent on the number of lone pairs. The bond angles are also influenced by the number of bonded atoms and their arrangement around the central atom, following the principles of VSEPR theory.

If the actual distance between the store and the dungeon is 4 kilometers, how far will the character have to travel in the game to visit all three destinations and return to their starting point?
The question is an illustration of scale drawing
The character have to travel 8.5 km in the game to visit all three destinations and return to their starting point
How to calculate the actual distanceThe distance on the map are given as:
A =2 cm
B = 8 cm
C = 7 cm
The total distance on the map would be:
\(Total =2cm + 8cm + 7cm\)
\(Total =17cm\)
The actual distance between the store and the dungeon is 4 kilometers.
This means that:
\(B' =4km\)
So, we have:
\(Scale = B : B'\)
\(Scale = 8cm : 4km'\)
Represent the required actual distance with x.
So, we have:
\(17cm : x = 8cm : 4km\)
Express as fraction
\(\frac{x}{17} = \frac 48\)
Multiply both sides by 17
\(x = \frac 48 * 17\)
\(x = 8.5\)

Each sandwich takes 10 minutes to make which means in the 10 hour shift there will be a total of 60 sandwiches. The deli wants an efficient way to increase the sandwich output using the same five workers and 10 hour shift (Don't Factor Break in) to produce 75 because of the 25% increase due to the expansion of the deli. What would you do to make the the process more efficient? Where each sandwich would take 8 minutes to make instead of 10 minutes. Please answer the question throughly.
Extra people required is 50.
Each of the five workers should increase their efficiency to a rate of 15 sandwiches per 10 hour shift.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Question 1 :
Number of associates = 30
Number of direct workers = 30 - 2 = 28
You work 8 hours a day and 5 days a week with two 15 minutes break or 30 minutes break per day.
Direct rate = 150 units per hour
Number of working hours in a week with break = 8 × 5 = 40 hours per week Number of working hours in a week = 7.5 hours per day × 5 days a week
= 37.5 hours per week
Units that department produce in a 40 hour week = 37.5 × 150 = 5625 units
28 people produce 5625 units in a week
Let x people produce 10,000 + 5625 = 15,625 units in a week
Using proportion,
28 : 5625 = x : 15,625
28 / 5625 = x / 15,625
x = (28 × 15,625) / 5625 = 77.78 ≈ 78
Extra people required = 78 - 28 = 50
Question 2 :
Number of sandwiches made in 10 minutes = 1
Number of sandwiches made in 10 hours = 60
5 workers are there. one worker makes 60/5 = 12 sandwiches
But Deli want number of sandwiches in 10 hours = 75
One worker should make 75/5 = 15 sandwiches instead of 12.
Number of sandwiches made in 8 minutes should be 1.
So the working efficiency on each worker should be increased and produce each one should produce 15 sandwiches in a 10 hour shift.
Hence extra people required in question 1 is 50 and efficiency of each worker in question 2 should be increased to 15 sandwiches in 10 hours shift.

12. Last month, a store sold a total of 182 pairs of jeans and shorts. The
number of shorts sold was 28 fewer than twice the number of jeans sold.
How many pairs of jeans were sold?
C. 105
A 51
D. 112
B. 70
Answer:
B. 70
Explanation:
A total of 182 pairs of jeans and shorts were sold and the number of shorts sold was 28 fewer than twice the number of jeans. This can be expressed with j being the number of jeans as:
j2 - 28 = number of shorts
As the number of shorts is 28 lower than twice the number of jeans, this means it can not be C or D, as these numbers are larger than 182 when doubled. The process of elimination can be done with the remaining using our equation.
51(2) - 28 = 102 - 28 = 74
70(2) - 28 = 140 - 28 = 112
Now that we have the number of shorts sold by using the equation, we can add them with what number was used as their number of jeans.
74 + 51 = 125
112 + 70 = 182
So the number of jeans sold is B. 70.
