Answer 1

Answer:

v=-14.4

Step-by-step explanation:

Isolate v.

add - 3.1 to the other side

-7.9+3.1=-4.8

Now the problem is:  -4.8 = v/3

Next, multiply both sides by 3

-4.8 times 3 = -14.4

v = -14.4

Answer 2

Answer:

-14.4

Step-by-step explanation:

-7.9 = -3.1 + (v/3)

- 4.8 = v/3

v = -14.4

KBL Ltd. entered into an agreement to lease a vehicle from Morgan Ltd.: Cash price of the vehicle Kshs 20.000 Lease payments: 5 instalments of Kshs 5.142 paid in arrears Required: How much of this finance charge will appear in each year's profit and loss expense in the lessee's books using the actuarial method? (10 Marks)​

Answers

Finance charge is the amount it costs of borrowing money

The finance charge that will appear in each year's profit and loss expense in the lessee's books are;

[tex]\begin{array}{|c|cc|}\mathbf{Year}&&\mathbf{Finance \ Charge \ (Kshs)}\\&&\\First&&1.8\\&&\\Second&&1.499\\&&\\Third&&1.171\\&&\\Fourth&&0.814\\&&\\Fifth&&0.424\end{array}\right][/tex]

The total financial charge = 5 × 5.142 - 20.000 = 5.71

The annual percentage rate, APR, of an instalment payment is given as follows;

[tex]\dfrac{(1 - (1 + r)^{-5}}{r} \times 5.142 = 20.000[/tex]

Solving using a graphing calculator gives;

r = APR ≈ 0.09 = 9%

The calculation for charges each year is as follows:

Payment interest for the first instalment = 20 × 9% = 1.8

The principal of the first payment = 5.142 - 1.8 = 3.342

The loan balance = 20 - 3.342 = 16.658

Payment interest for the second instalment = 16.658 × 9% = 1.49922

Second payment principal = 5.142 - 1.49922 = 3.64278

Loan balance = 16.658 - 3.64278 = 13.01522

Payment interest for the third instalment = 13.01522 × 9% = 1.1713698

Third payment principal = 5.142 - 1.1713698 = 3.9706302

Loan balance = 13.01522 - 3.9706302 = 9.0445898

Interest for the fourth payment = 9.0445898 × 9% = 0.814013082

Fourth payment principal = 5.142 - 0.814013082 ≈ 4.327986918

Loan balance = 9.0445898 - 4.327986918 = 4.716602882

Fifth payment interest = 4.716602882 × 9% = 0.42449425938

Fifth payment principal = 5.142 - 0.42449425938 ≈ 4.718

Therefore, we have;

[tex]\begin{array}{|c|cc|}\mathbf{Year}&&\mathbf{Finance \ Charge \ (Kshs)}\\&&\\First&&1.8\\&&\\Second&&1.499\\&&\\Third&&1.171\\&&\\Fourth&&0.814\\&&\\Fifth&&0.424\end{array}\right][/tex]

What is a 15 of the sequence –7,2, 11, ...?

Answers

We can see: Everytime, the new number is the sum of the number behind it with 9.

So the 15th will total add: 9 x 14 = 126

Start from number -7 so the 15th number is : 126 -7 = 119

SO: B.119 is the answer

NL: Sorry my english was bad

Answer:

119

Step-by-step explanation:

We need to find the 15th term in the sequence. The pattern is that each term increases by 9.

We can then count to the 15th term

-7 + 14*9 = 119

Therefore, the 15th term is equal to 119, or answer B.

if the cost price of 10 tables is equal to the selling price of 16 tables , find out the gain or loss percentage​

Answers

Hi,

To solve this problem, Let us take the LCM of 10 and 16 which will come 80.

Now suppose the cost price of 10 tables =₹n CP of 80 tables will be ₹ 8n

According to the question, CP of 10 tables is equal to the SP of 16 tables, then

the SP of 16 tables will also be ₹ n.

So, SP of 80 tables will be ₹ 5n

So, Loss = CP-SP

→ 8n - 5n = ₹ 3n

Loss%= (3n×100)/8n

Loss%= 37.5%.

Hence the correct answer will be a loss of 37.5%.

The center circle on a soccer field has a radius of 9 yards. What is the area of the center circle? Use 3.14 for pie

Answers

Answer:

[tex]\boxed {\boxed {\sf 254.34 \ yd^2}}[/tex]

Step-by-step explanation:

The area of a shape is the space occupied by the surface of an object. The area of a circle can be calculated using the following formula.

[tex]a= \pi r^2[/tex]

The radius (r) of the center circle on the soccer field is 9 yards. We are asked to use 3.14 for pi.

r= 9 yd π= 3.14

Substitute these values into the formula.

[tex]a= (3.14)(9 \ yd)^2[/tex]

Solve the exponent.

(9 yd)² = 9 yd * 9 yd = 81 yd²

[tex]a= (3.14)(81 \ yd^2)[/tex]

Multiply.

[tex]a= 254.34 \ yd^2[/tex]
