You are applying for an 80/20 mortgage to buy a house costing $145,000. The first (80%) mortgage has an interest rate of 4.75%, and the second (20%) mortgage has an interest rate of 7.525%. Both the first mortgage and the second mortgage are 30-year fixed-rate mortgages. What will the total amount of the mortgage be?
Answers
Answer:
$291,016.80
A is correct.
Step-by-step explanation:
You are applying for an 80/20 mortgage to buy a house costing $145,000.
Loan Formula:
[tex]EMI=\dfrac{P\cdot r}{1-(1+r)^{-n}}[/tex]
Case 1:
Loan amount, P = 80% of 145000 = $ 116,000
Rate of interest, r = 4.75% = 0.0475
Time of loan, n = 30 years = 360 months
Substitute the values into formula.
[tex]EMI=\dfrac{116000\cdot \frac{0.0475}{12}}{1-(1+\frac{0.0475}{12})^{-360}}[/tex]
[tex]EMI=605.11[/tex]
Total payment for case 1: 605.11 x 360 = $217,839.60
Case 2:
Loan amount, P = 20% of 145000 = $ 29,000
Rate of interest, r = 4.75% = 0.07525
Time of loan, n = 30 years = 360 months
Substitute the values into formula.
[tex]EMI=\dfrac{29000\cdot \frac{0.07525}{12}}{1-(1+\frac{0.07525}{12})^{-360}}[/tex]
[tex]EMI=203.27[/tex]
Total payment for case 1: 203.27 x 360 = $73,177.20
Total amount of the mortgage = $217,839.60 + $73,177.20
= $291,016.80
Hence, The total amount of the mortgage is $291,016.80

The total amount accrued, principal plus interest, with compound interest on a principal of $5,000.00 at a rate of 4% per year compounded 1 times per year over 3 years is $5,624.32.
Given Data
Principal = $5000Rate = 4%Time = 3 yearsA = P + I where
P (principal) = $5,000.00
I (interest) = $624.32
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 4/100
r = 0.04 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 5,000.00(1 + 0.04/1)^(1)(3)
A = 5,000.00(1 + 0.04)^(3)

There are six girls and seven boys in the class a team of 10 players is to be selected from the class how many different combinations of players it is possible
Answers
Answer:
In 286 different ways 10 players can be selected.
Step-by-step explanation:
There are 6 girls and 7 boys in a class. So in total there are 6+7 = 13 number of students in the class.
A team of 10 players is to be selected from the class.
As there is no other conditions are given, we can pick any 10 students from 13 students.
The way we can select 10 players from 13 students is;
= (13 10)
= 13!/10!(13-10)!
= 13!/10! 3!
= (13 × 12 × 11 × 10!)/ 10! 3!
= ( 13 × 12 × 11)/6

Answer:
Smaller x -10
Larger x -2
Step-by-step explanation:
f(x) = (x+6) ^2 - 16
To find the zero's, we set the function equal to zero
0 = (x+6) ^2 - 16
Add 16 to each side
16 = (x+6) ^2 - 16 + 16
16 = (x+6)^2
Take the square root of each side
±sqrt(16) = sqrt((x+6)^2))
±4 = x+6
Subtract 6 from each side
-6±4 = x+6-6
-6±4 = x
-6 -4 = x -6+4 =x
-10 =x -2 =x
Smaller x -10
Larger x -2
Answer:
Smaller x: -10
Larger x: -2
Step-by-step explanation:
You are looking for where the function equals 0. So, you can set f(x) equal to 0:
f(x) = [tex]0=(x+6)^{2} -16[/tex]
Now add 16 to both sides:
[tex]16=(x+6)^{2}[/tex]
Now that you have a perfect square on both sides, you can take the square root of both sides. On the right, this would simply remove the exponent. On the left, you have the square root of 16, or 4. It is important to remember that this can be positive or negative (since -4 squared also equals 16).
±4 = x + 6
To find your two solutions, you have to then evaluate the equation for 4 and -4. First, with -4:
-4 = x + 6 subtract 6 from both sides
-10 = x
Now, with 4:
4 = x + 6 subtract 6 from both sides
-2 = x
And there are your two solutions. Since -10 < -2, -10 is the smaller x and -2 is the larger one.

What is the value of s to the nearest whole number? HELP!
Answers
Answer:
14
Step-by-step explanation:
Using the law of cosines on ΔRST, then
s² = 9² + 8² - (2 × 9 × 8 × cos111° )
= 81 + 64 - ( 144 × cos111° )
= 145 - (- 51.6)
= 145 + 51 . 6 = 196.6 ( take the square root of both sides )
s = [tex]\sqrt{196.6}[/tex] ≈ 14
The answer is: 14
Why?Using the law of cosines and the given information, we can find the value of s.
Law of cosines is:
[tex]a^{2}=b^{2}+c^{2}-2abcos(A)[/tex]
Where,
[tex]a=s\\b=9\\c=8\\A=111(degrees)[/tex]
By substituting we have:
[tex]s=\sqrt{9^{2}+8^{2}-2*9*8*cos(111)}\\\\s=\sqrt{81+64-(144)*(-0.35)}=\sqrt{145+50.4}=\sqrt{195.4}=13.98=14[/tex]

A store has apples on sale for $28.00 for 8 pounds. If an apple is approximately 5 ounces, how many apples can you buy for $168.00? Complete the explanation.
The cost per pound of the apples on sale is $
.
You can buy
pounds of apples for $168.00.
Since 1 pound = 16 ounces, so there are about
apples in each pound.
You can buy approximately
apples for $168.00.
Answers
To determine how many apples you can buy for $168.00, you first calculate the cost per pound to be $3.50. Then, calculate that you can buy 48 pounds of apples, and since there are about 3.2 apples per pound, you can purchase approximately 153 apples for $168.00.
To determine how many apples you can buy for $168.00, let's start by calculating the cost per pound of the apples on sale, which is $28.00 for 8 pounds. This yields a cost per pound of $3.50.
Next, we'll find out how many pounds of apples you can buy for $168.00. By dividing $168.00 by the cost per pound ($3.50), we get 48 pounds of apples.
Since 1 pound equals 16 ounces, and each apple is approximately 5 ounces, we can calculate how many apples are in each pound by dividing 16 by 5, which gives us about 3.2 apples per pound.
Lastly, to find out the total number of apples you can buy for $168.00, we multiply the total pounds of apples (48) by the number of apples per pound (3.2), resulting in a total of approximately 153.6, which we can round down to 153 apples.

What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given that Point O is the center of the circle
We have to find the value of x
arc PN is 114 degrees because it’s congruent to the central angle.
We know that the total measure of triangle is 360 degrees
By removing arc PN the remaining circle has 246 degrees of measure
Divide the difference of intercepted arcs (246 and 114) by 2 to get the angle formed by the tangents.

b. What is Jacob’s monthly bill if he uses 124.8 minutes?
Answers
Answer:
B. Jacobs monthly bill shall be $48.75
Step-by-step explanation:
On this specific mont, Jacob used 124.8 minutes.
Considering that every fraction of a minute is rounded off to the next minute,
Jacob used 125 minutes.
Each minute goes for $0.35
Now multiply total nomber of minutes by $0.35 rate
0.35 * 125 = 43.75
This is bill for the minutes used.
The bill for service is $5 per month.
To get the total bill, we add $5 to $43.75
Which gives us $48.75
