X= the number
2x+12=3x-31

2x-3x= -31x-12

What is the value of sin(A) ?
iVinArrow [24]

Triangles ABC and XYZ are similar, so the corresponding angle to A in XYZ triangle is angle X. We can actually find sin(X) very easily.

Because we know all sides and the right angle, we can use certain formula to find sin(X), like this:

sin(X) = opposite side / hypotenuse = 6/10 = 3/5

sin(X) = sin(A)

The correct answer is sin(A) = 3/5.

John bought a used truck for $4,500. He made an agreement with the dealer to put $1,500 down and make payments of $350 for the n
musickatia [10]

Answer:

(D) 36%

Step-by-step explanation:

Actual cost of truck = $4500

Down payment = $1500

Money left to be paid = 4500-1500 =  $3000

A = Monthly payments = 350

n = 10

Principal value (P) = 3000

Using formula,

A= \frac{Pr(1+r)^{n}}{(1+r)^{n}-1}

350 =\frac{3000r(1+r)^{10}}{(1+r)^{10}-1}

       = 36% (approx)

Hence (D) is correct.
