What is the approximate distance between Portland, Oregon (45° north, 122° west), and San Francisco, California (37° north, 122° west). Use 3,960 miles for the radius of Earth.258 miles



553 miles



720 miles



1,346 miles

Answers

Answer 1
Answer: From the given data in the problem, the longitude is essentially the same, and using the coordinates, the locations are 8° apart. The 8° is 8/360 of the circumference of the circle. The circumference is 2π • 3960.   Substituting,  (8 • 2π • 3960) / 360 = 4π • 44 = 553 miles. Thus, option B is the answer. 
Answer 2
Answer:

The correct answer is

553 miles

The easyiest but not the only, way to solve this problem is the FOIL method. You first do a*a=a^2 then a*-2=-2a then a*3=3a then 3*-2=-6 then you add it all together a^2-2a+3a-6 then simplify. so the answer is a^2+a-6! Any more questions?

Jerome is writing a number in scientific notation. The number is greater than one million and less than ten million. What will be the exponent in the number Jerome writes?PLEASE HELP!!!!(by that i mean i want the answer)

Answers

The exponent in the number Jerome writes will be anywhere between 6 to 7.

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

Jerome is writing a number in scientific notation.

Let's suppose the number is x

The number x is greater than one million and less than ten million.

In scientific notation:

\rm 10^6\leq x\leq 10^7

We can say that from the above inequality that the exponent of the number will be between 6 to 7.

Thus, the exponent in the number Jerome writes will be anywhere between 6 to 7.

One million: 10^6

Ten million:  10^7

So the exponent will be anywhere between 6 and 7, inclusive

Write 19/24 as a decimal rounded to the nearest tenth

Answers

Answer:

The answer is 0.8

Step-by-step explanation:

Firstly, you have to know the position of the tenth decimal.

Give a decimal number, for example, 114.325

The position of the tenth decimal places to the right of the decimal point. In this case, the number 3 is in the position of the tenth place.

Also, you have to know how to round a decimal number. The rule says:

If you want to round a number with a n-decimal digits, you have to see the position n+1-decimal digit:

If this number is equal or greater than 5, you have to increase the n-decimal digit to the next whole number.

If this number is lesser than 5, you have to decrease the n-decimal digit to the previous whole number.

Using the example 114.325

If we want to round the decimal number to the nearest tenth, the next digit is a 2, so we dont increase the number 3. So the decimal number is 114.3

Finally, responding your question,

First you have to represent the fraction number into decimal number.

(19)/(24) =0.791666

The nearest tenth is the first decimal digit: 7

The next number is a 9, so if we want to round to the nearest tenth, we will have to increase the number 7 to the next whole number: 8

The final answer is 0.8

The calculated division of the numbers 19/24 into a decimal number is 0.8

How to calculate the division of the numbers

From the question, we have the following parameters that can be used in our computation:

19/24 into a decimal number

When represented as an equation, we have

19/24 into a decimal number = 19/24

Expand

19/24 into a decimal number = 19/24

Divide 19 by 24

So, we have the following result

19/24 into a decimal number = 0.79166666666

Approximate to the nearest tenth

19/24 into a decimal number = 0.8

Using the above as a guide, we have the following:

the result is 0.8
