Maria is buying a car for $18,510. She will finance $13,000 of it with a 3-year loan at 2.8% APR. What will her monthly auto pay

Eva8 [605]

Answer-

Maria's monthly payment will be $376.91

Solution-

Maria is buying a car worth of $18,510, but she will finance only $13,000 of it with a 3-year loan at 2.8% APR.

We know that,

$\text{PV of annuity}=P[\dfrac{1-(1+r)^{-n}}{r}]$

Here,

$\text{PV of annuity=13000},\\\\\text{P=??},\\\\\text{r = 2.8\%\ annually}=\frac{2.8}{12}\text{\%\ monthly}\\\\\text{n=3 years=36 months}$

Putting the values,

$\Rightarrow 13000=P[\dfrac{1-(1+\frac{2.8}{1200})^{-36}}{\frac{2.8}{1200}}]$

$\Rightarrow 13000=P\times 34.4909$

$\Rightarrow P=\dfrac{13000}{34.4909}$

$\Rightarrow P=376.91$

Therefore, her monthly payment will be $376.91

Solve for v. Show your work 10 - (3v - 1) = 5(9 - v)

Whitepunk [10]

Answer:

The value of v is -17.

Step-by-step explanation:

10-(3v-1)=5(9-v)

10-3v+1=45-v

11-3v=45-v

11-45=3v-v

-34=2v

-34÷2=v

-17=v

Need a little help does anyone’s know how to do this?

hichkok12 [17]

Answer:

106°

Step-by-step explanation:

Given that the points B, C and D are colinear, it means that

2x + 40 = 5x + 10

collecting like terms

40 - 10 = 5x - 2x

3x = 30

x = 10

Hence the angle ∠E

= 5(10) + 10

= 60°

∠BCE = X + 4

= 10 + 4

= 14°

Given that the sum of angles in a triangle is 180°

∠D + 14 + 60 = 180

∠D = 180 - 74

= 106°

Three friends bought 4, 6, and 8 books. The table shows the cost of the books.

Pepsi [2]

Answer:

Option (B) is correct .

The constant of proportionality is 7.5 .

Reason

Let us assume that the number of books be x.

Let us assume that the cost of books be y .

Than

$y \propto x$

y = kx

Where k is constant of proportionality .

As given

Number of Books 4 6 8

Cost ($) 30 45 60

Thus

when x = 4 , y = 30

Put in the equation y = kx .

$30 = 4k$

$k = \frac{30}{4}$

k = 7.5

when x = 6 , y = 45

Put in the equation y = kx .

$45 = 6k$

$k = \frac{45}{6}$

k = 7.5

when x = 8 , y = 60

Put in the equation y = kx .

$60 = 8k$

$k = \frac{60}{8}$

k = 7.5

Therefore the constant of proportionality is 7.5 i.e option (B) is correct .
