Answer: 327 \text{ounce}

Step-by-step explanation:

Given: On the way home from school, ross wears his 20 pound backpack and carries his 7 ounce lunchbox.

To Find: how many ounces does he carry in total.

Solution:

Weight of Ross's backpack =20 \text{pound}

Weight of Ross's lunchbox =7 \text{ounce}

Now,

As unit of weight of backpack and lunchbox is different, we need to convert it.

1 \text{pound} =16 \text{ounce}

Now weight of backpack is=\text{weight in pound}\times16

                                 20\times16

                                 320 \text{ounce}

Total ounces carried by Ross =\text{weight of backpack}+\text{weight of lunchbox}

                                                 320+7 \text{ounce}

Hence Total ounce carried by Ross is 320+7 \text{ounce}

Electrical resistance ina wire is directly proportional to its length and inversely proportional to the square of its diameter.
LenaWriter [7]
Initial Conditions:

length=L= 10 cm = (10*10⁻²)m
Diameter=D= 2 cm= (2*10⁻²)m
Radius= r= 0.01m
Area=A= π*r²/2 =1.57*10⁻⁴ m²

Resistance=R= 600 ohm
 
So, from initial conditions we find resistivity(р)
                                       R=рL/A
                                       R*A /L=р
                                      (600)*(1.57*10⁻⁴)/(10*10⁻²)=р
                                       р=0.942 Ω m
<span>As, material remains same so resistivity(p) doesn't change

 </span>Lenght= L1= 15 fm= 15*10⁻¹⁵ m
Diameter= D1 = 5 cm= 5*10⁻² m
Radius= r= 0.025 m
Area= A1= π*r²/2 =9.8125*10⁻⁴ m²
                                               R=р*L1/A1
                                               R=(0.942 )*(15*10⁻¹⁵ )/(9.8125*10⁻⁴)
                                               R=1.44*10⁻¹¹ Ω

You have decided to purchase a car for $25,625. The credit union requires a 10% down payment and will finance the balance
swat32

Answer:

Total purchase = $28498.685

In cent = 2849868.5 cent.

Step-by-step explanation:

Given : You have decided to purchase a car for 175.13.

To find : What is the total purchase price of the car including tax, license, and title?

Solution :

Price of car = $25,625

Sales tax = 7.5% = 0.075

The total purchase price of the car including tax is

T=25625\times 0.075=\$1921.875T=25625×0.075=$1921.875

Title charges are $175.13.

The credit union requires a 10% down payment and will finance the balance with a 9% annual interest loan for 36 months.

10% down payment on price of car

25625\times 0.10=2562.525625×0.10=2562.5

25625-2562.5=23062.525625−2562.5=23062.5

The amount will be $23062.5

Now, we find the monthly payment,

Monthly payment, M=\frac{\text{Amount}}{\text{Discount factor}}M=

Discount factor

Amount

​

Discount factor D=\frac{1-(1+i)^{-n}}{i}D=

i

1−(1+i)

−n

​

Rate = 9%=0.09

i=\frac{0.09}{12}=0.0075i=

12

0.09

​

=0.0075

Time n=36 month

Now, put all the values we get,

D=\frac{1-(1+i)^{-n}}{i}D=

i

1−(1+i)

−n

​

D=\frac{1-(1+0.0075)^{-36}}{0.0075}D=

0.0075

1−(1+0.0075)

−36

​

D=\frac{1-(1.0075)^{-36}}{0.0075}D=

0.0075

1−(1.0075)

−36

​

D=\frac{0.2358}{0.0075}D=

0.0075

0.2358

​

D=31.44D=31.44

Monthly payment, M=\frac{\text{Amount}}{\text{Discount factor}}M=

Discount factor

Amount

​

M=\frac{23062.5}{31.44}M=

31.44

23062.5

​

M=733.38M=733.38

Monthly payment is $733.38

For 36 months the payment is 733.38\times 36=26401.68733.38×36=26401.68

Licence = $26401.68

The total purchase price of the car including tax, license, and title

Total purchase = 1921.875 +1921.875+175.13 +$26401.68

Total purchase = $28498.685

1 dollar = 100 cent

$28498.685 = 2849868.5 cent.
