Write the expanded form 0.45 in this way using fractions and using decimals

Answers

Answer 1

Answer:

Using fractions, 0.45 can be written as $(3)/(10)$ + $(3)/(20)$ . Using decimals, 0.45 can be written in the form as 0.30 + 0.15.

What is Decimal Numbers?

Decimal number system is applicable for both integers as well as non integers. Decimal number include a whole number part and a decimal part separated using decimal point.

Fractions are the numbers which are part of a whole.

All decimal numbers can be written as fractions and fractions can be written in the form of decimal numbers.

The given number is 0.45.

0.45 can be written as $(45)/(100)$ .

$(45)/(100)$ can be expanded in various ways like (40 + 5)/100, (42 + 3)/100 and so on.

$(45)/(100)$ can be written in one of the form as $(30)/(100)$ + $(15)/(100)$ .

When simplified, $(30)/(100)$ simplified to $(3)/(10)$ and $(15)/(100)$ simplified to $(3)/(20)$ .

So 0.45 = $(3)/(10)$ + $(3)/(20)$ .

Now, in the decimal form, $(3)/(10)$ = 0.3 and $(3)/(20)$ = 0.15

So, 0.45 = 0.3 + 0.15

Hence 0.45 can be expanded in the fractional form as $(3)/(10)$ + $(3)/(20)$ and in the decimal form as 0.3 + 0.15.

The center of the circle is located (3'8), and the circle has a radius that is 5 units long. What is the general form of the equation for the circle

Answers

9514 1404 393

Answer:

x² +y² -6x -16y +48 = 0

Step-by-step explanation:

Given:

circle center: (3, 8)
circle radius: 5

Find:

general form equation for the circle

Solution;

The standard form equation for the circle is ...

(x -h)² +(y -k)² = r² . . . . . circle with radius r centered at (h, k)

(x -3)² +(y -8)² = 5²

Subtracting 25 and expanding this will give the general form.

x² -6x +9 +y² -16y +64 -25 = 0

x² +y² -6x -16y +48 = 0

_____

Additional comment

"General form" of an equation is usually the form f(x,y) = 0, where f(x, y) is written in "standard form," with terms in lexicographical order and decreasing degree.

A car traveled 480 miles in 4 hours. If its speed was 12 mph faster, what distance would it have traveled in 4 hours?

Answers

Answer:

528 miles

Step-by-step explanation:

First, we need to figure out how many miles it drives in 1 hour:

480 divided by 4 = 120

now, we add 12 to 120: 120 + 12 = 132

132 x 4 = 528

hope this helped have a great day/night!! :'')

Final answer:

The car would have traveled 528 miles in 4 hours with the increased speed of 12 mph.

Explanation:

To calculate the distance the car would have traveled in 4 hours with a speed that is 12 mph faster, we need to find the original speed of the car. We can use the formula speed = distance/time, where the speed is the original speed of the car, the distance is the distance the car traveled in 4 hours (480 miles), and the time is 4 hours. Rearranging the formula, we have distance = speed x time. So, the distance the car would have traveled with the increased speed in 4 hours is 480 miles + 12 mph x 4 hours.

Using the formula, we can calculate the distance:
distance = (480 miles) + (12 mph x 4 hours) = 480 miles + 48 miles = 528 miles.

Therefore, if the car's speed was 12 mph faster, it would have traveled a distance of 528 miles in 4 hours.

Mr. Kazadi said that in his 2nd-period class, 23 out of 25 students passed the test. What percent of the students passed the test?%

Answers

The answer 92% of students passed the test.

$\text{Hello there!}$

To find a percentage, you will need to divide both numbers by each other. In this case, it would look similar to this:

$\text{23 / 25 = ???}$

Once you divide the two numbers, you should end up with a result of $0.92$

Now, we are going to move the decimal two spaces to the right to end up with the result:

$\text{092.}$

Now, we are going to remove the $0$ as it is no longer required. Next, add a percentage symbol to the last number, and remove the decimal from the number.
