Mathematics
1 answer:
dalvyx [7]3 years ago
6 0

Answer:

Step-by-step explanation:

This is 30°-60°-90° triangle, so the sides are in the ratio 1:√3:2

The side opposite the 30° angle is 10√3, so the side opposite the 60° angle is √3×10√3= 30, and the side opposite the 90° angle is 2×10√3 = 20√3.

Which expression is equivalent to −1/ 12x−1 /3?
alexandr402 [8]

Answer:

\frac{1}{12} (-x-4)

Step-by-step explanation:

the expression we have is:

-\frac{1}{12} x-\frac{1}{3}

To find an equivalent expression, it would be helpful to express 1/3 so that it has a 12 in the denominator:

\frac{1}{3}=\frac{4}{12}

so we substitute this:

-\frac{1}{12} x-\frac{4}{12}

and now we have 1/12 in both terms :

-\frac{1}{12}x-\frac{1*4}{12}

so we can factor it (we take it out of each term: in the first we are left with -x and in the second with -4):

\frac{1}{12} (-x-4)

the equivalent expression is: \frac{1}{12} (-x-4)

Make a down payment of $1500 and finance the rest of $20000 at 1.9% interest rate, making equal monthly payments for 5 years.
pshichka [43]
We know that we have to m<span>ake a down payment of $1500 and finance the rest of $20000 at a 1.9% interest rate, making equal monthly payments for 5 years. Our first step to solve this problem would be to convert 5 years into months. 

1 year = 12 months 

12 * 5 = 60 months 

Therefore, in 5 years there are 60 months. 

Now lets solve this problem step by step. 

Subtract the down payment from $20,000

</span>$20000-$1500=$18500

Multiply the remaining number by the interest rate. 

$18500 *1.9 = $35150 

Divide 35150 by number of months in 5 years (60)

$35150 / 60 = $585 

<span>Therefore, you have to pay $585 per month. </span>
