Answer:

-5\:\mathrm{and}\: 11

Step-by-step explanation:

We can write the following system of equations:

\begin{cases}x+y=6\\x-y=16\\\end{cases}

Adding both equations together, we isolate x and get:

2x=22,\: x=11

Plugging x=11 in any of the equations, we can solve for y:

11+y=6,\: y=-5

Verify that the solution pair (11, -5) works \checkmark

Therefore, the two numbers are \fbox{$-5\:\mathrm{and}\: 11$}.

Choose the correct answers for (a) the total installment price, (b) the carrying charges, and (c) the number of months needed to
Brrunno [24]
Part A:

Given that <span>a dinette table with a cash price of $200 is purchased at $8.50 down and $11.00 per month for 24 months

The total installment price is given by

P=\$8.50+\$11(24) \\  \\ =\$8.50+\$264=\$272.50



Part B:

The carrying charges is given by the total installation price minus the cash price.

From part a, we obtained that the total installation price is $272.50 and given that the cash price is $200.

Therefore, the carrying charges is given by

$272.50 - $200.00 = $72.00



Part C:

If the money is to be saved at $11 per month to be able to purchase the table at the cash price, the number of months it will take to be able to save $200 at $11 per month is given by

\frac{\$200}{\$11} =18.18\, months

Therefore, it will take 19 months </span><span>to save the money at the monthly rate needed to buy the item for its cash price.</span>

Each day, the human heart pumps about 7500 liters of blood. As a simple approximation, assume that the work done by the heart is
erik [133]

Answer with Step-by-step explanation:

We are given

Volume of blood=V=7500 L=7500\times 0.001=7.5 m^3

1 liter=0.001 m^3

Height of person=h=1.5 m

Density of blood,\rho=1050 kg/m^3

We have to find the work done and power of person's heart.

We know that

Work done,W=mgh=\rho Vgh

Where g=9.8 m/s^2

Using the formula

W=1050\times 7.5\times 9.8\times 1.5=1.16\times 10^5 J

Time,t=1 day=24\times 60\times 60=86400 s

Power, P=\frac{W}{t}

Using the formula

P=\frac{1.16\times 10^5}{86400}=1.34 Watt
