Answer:

x = 20
y = 114°

Step-by-step explanation:

An exterior angle of a triangle is equal to the sum of the remote interior angles.

(3x +6)° = 31° +35°

3x +6 = 66 . . . . . . . . . . divide by °, collect terms

3x = 60 . . . . . . . . subtract 6

x = 20 . . . . . . . divide by 3

The value of y is the supplement of (3x+6)°, and of the sum (31 +35)°.

y = 180° -66° = 114°

The values of x and y are 20 and 114°, respectively.

Step-by-step explanation:

2.99 * 1= 2.99

First you had to multiply 2.99 by 1 because 100% in decimal is 1.

Find the amount and present value of 10 quarterly payments of $ 1500, if the interest rate is 25% compounded each month.

BlackZzzverrR [31]

Given Information:

Monthly payment = MP = $1500/4 = $375

Monthly interest rate = r = 25/12 = 2.083%

Required Information:

Present Value = ?

Answer:

$PV = \$10,110$

Explanation:

n = 10*4

n = 40 monthly payments

The present value is found by

$PV = MP \times \frac{ (1 - \frac{1}{(1+r)^n} )}{r}$

Where r is monthly interest rate.

MP is the monthly payment.

$PV = 375 \times \frac{ (1 - \frac{1}{(1+0.02083)^{40}} )}{0.02083}$

$PV = 375 \times (26.96)$

$PV = \$10,110$

Therefore, $10,110 is the present value of 10 quarterly payments of $1500 each at 25% interest rate compounded each month.
