Answer: 1.08j

Step-by-step explanation: if we add 8% of something to itself, we now have 108%, right

1.08j

I’m not 100% sure tho

The expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As it is given that the cost of the jacket is j, while the tax on the jacket is 0.08j. therefore, the total cost of the jacket can be written as the sum of the cost of the jacket and the tax on the jacket.

Thus, the total cost of the jacket = Cost of jacket + Tax on the jacket

                                                       = j + 0.08j

                                                       = 1.08j

Hence, the expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

Scientific: 3*10^2

Standard: 300

2)

Scientific: 4.5*10^5

Standard: 450000

3)

Scientific: 1.5*10^-3

Standard: 0.0015

Step-by-step explanation:

There is a rule in mathematics that goes like this: If you have an exponent divided by an exponent and they have the same base, it is the same thing as subtracting it from each other.  

Example: if we had [tex]\frac{10^5}{10^3}[/tex], we could subtract 3 from 5 and get 2, and therefore our answer would be 10^2.  

We can apply this rule to all three of these problems.  

1) If we subtract the exponents, we get 9-7=2. Therefore our new exponent will be 2.  Next, divide the two numbers multiplying 10.  They are nine and three. 9/3 is 3, so our answer is 3*10^2.  Next we convert to standard form.  Multiply 3 time 10^2, and you get your answer.  10^2 is 100, 3*100 is 300, so our answer in standard form would be 300.  

You can repeat this same process with all of the problems.

Number of layers of graphene are there in a 1.6mm thick piece of graphite is,

⇒ 8 × 10⁶

Scientific notation is a way of writing a very large or very small numbers.

For example; 230,000,000 can be written in scientific notation as 2.3 x 10⁸.

Given that;

Graphite is made up of layers of graphene. Each layer of graphene is about 200 picometers, or 200 x 10⁻¹² meters thick.

Hence, Number of layers of graphene are there in a 1.6mm thick piece of graphite is,

⇒ 0.0016 m / 200 x 10⁻¹² m / layer

⇒ 8 × 10⁶

Thus, Number of layers of graphene are there in a 1.6mm thick piece of graphite is,

⇒ 8 × 10⁶

Answer:

155 degrees

Step-by-step explanation:

supplementary angles add up to equal 180°

To find an angles supplement we can subtract the measure of the given angle ( 25 )  from 180

180 - 25 = 155

Hence, the measure of the other angle is 155 degrees

∠AOB and ∠BOC make a right angle of 90°.

x+8+2x=90

3x+8=90

3x=82

x=27.3333333

Answer:

27.34

Step-by-step explanation:

x + 8 + 2x = 90

x + 2x = 90-8

3x = 82

x = 82/3

x = 27.33333333333333333333

Answer: 60 miles/hour

Step-by-step explanation:

Departure time:  5:30

Arrival time:  8:30

Distance = 180 miles

Total time it took to travel = 3 hours.

Recap:  Distance = (Speed) × (Time)

Plug the number into the formula:

    180miles = (speed) × 3hours

Solve for speed by dividing both sides by 3 hours:

    180miles/3hours = Speed

Simplify:

    60 miles/hour = Speed
