Make a down payment of $1500 and finance the rest of $20000 at 1.9% interest rate, making equal monthly payments for 5 years.

7 0

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>

Answer:

(-infinity, 0)

(0, 4]

[30, infinity)

Step-by-step explanation:

The inequality seems a little weird since it doesn't reflect the formula for speed accurately. The right inequality should be:

average speed >= 24

(first half speed + second half speed)/2 >= 24

(x+ (x-10))/2 >= 24

x-5>=24

x>= 29

In this case, the answer should be only [30, infinity)

If I solve the inequality given by the problems, the result will be:

1/x + 1/ (x-10) >= 2/24 ---> multiply both side with x(x-10)

x-10 + x >= (2x^2-20x)/24 ---> move /24 to left side

48x-240 >= 2x^2-20x ---> move all left side to right side

0>=2x^2 -68x+240 ---> divide both side by 2

0>=x^2 - 34x +120

0>=x^2-30x -4x+120

x(x-30) -4 (x-30)

(x-4) (x-30)

x1=4 x2=30

Since the coefficient of x^2 is positive so only area between two result is negative.

The answer will be

x1= (-infinity, 4]

x1= (-infinity, 0) , (0, 4]

x2= [30, infinity)

Answer:

$\boxed{\text{D. 11.6 lb}}$

Step-by-step explanation:

The mean is the sum of the weights divided by the number of weighings.

$\text{Mean}= \dfrac{13.5 + 12.5 + 10.5 + 11.2 + 11.2 + 10.8 + 9.5 + 13.4 + 11.5 + 11.8}{10}\\\\= \dfrac{115.9}{10} \approx \mathbf{11.6}\\\\\text{Heather is predicting that Sally will weigh } \boxed{\textbf{11.6 lb}}$
