What percent of a circle is 2/5 of a circle? Explain

Answers

Answer 1

40 percent 2 divided by 5 equals .4

Answer 2

Final answer:

2/5 of a circle is equivalent to 40% of the circle. This is determined by multiplying 2/5 by 100%.

Explanation:

In the field of

Mathematics

, a circle is divided into an angle of 360 degrees or 100 percent. If we want to find out what percent of a circle is 2/5 of a circle, we need to perform a simple calculation.

Firstly, note that 1 whole circle (or 360 degrees) is equivalent to 100%.

When we say 2/5 of a circle, we are referring to 2/5 parts of the whole circle.

To find out what percent 2/5 of the circle is, we multiply 2/5 by 100%:

(2/5) * 100% = 40%

This means that 2/5 of a circle is 40% of the whole circle.

Answers:

1) [B]: "12.5%" .
_________________
2) [B]: "70.9%" .
_________________
3) "66[tex] \frac{2}{3} [/tex]%" ; or, "66.6666... % " ; or, round to: "66.667 %" ;
or; round to: "66.67%" .
_____________________________________
Explanation:
_____________________________________
1) "Rename one-eight as a percent".

→ [tex] \frac{1}{8}[/tex] = 1 ÷ 8 = 0.125 ;

→ [tex] \frac{x}{100}[/tex] = 0.125 ;

→ x = 0.125 * 100 = {move the decimal point in the number, "0.125"; two spaces forward, since we are MULTIPLYING, by "100" (which has 2 zeros);
→ x = 12 * 100 = 12.5 .

So: → [tex] \frac{12.5}{100}[/tex] = 12.5 % ; since "12.5 % = 12.5/100 "
_____________________________________
Other method:
_____________________________________
→ [tex] \frac{x}{100}[/tex] = [tex] \frac{1}{8}[/tex] ;

→ x = 100 * [tex] \frac{1}{8}[/tex] ;

→ x = [tex] \frac{100}{1}[/tex] * [tex] \frac{1}{8}[/tex] ;

=   [tex] \frac{100*1}{1*8} [/tex] ;

=   [tex] \frac{100}{8} [/tex] ;

→ x = 12.5 ;

→ [tex] \frac{x}{100} [/tex] = [tex] \frac{12.5}{100} [/tex] = 12.5% ;

→ 12.5 % = [tex] \frac{12.5}{100} [/tex] ;
= ?

→ {Take the "12.5" & move the decimal backward TWO (2) places, since we are "dividing" by "100" (which has 2 "zeros") ;

= 0.125 = [tex] \frac{125}{100}[/tex] = [tex] \frac{1}{8} [/tex].
_________________________________________________
2) "Rename "0.709" as a percent."

===> [tex] \frac{x}{100} [/tex] = 0.709 ;

  → x = 0.709 * 100 = ? ;

Note: Take the "0.709" ; & move the decimal place "2 (TWO)" spaces forward, since are MULTIPLYING by "100" (which has 2 zeros); to get:
→ x = 70.9 ;

  → x = 0.709 * 100 = 70.9 ;

→ [tex] \frac{x}{100} [/tex] =  [tex] \frac{70.9}{100} [/tex] = 70.9% ;
  → which is: Answer choice: [B] .

→ 70.9% = [tex] \frac{70.9}{100} [/tex] = ? ;

{take the "70.9" ; and move the decimal point backwards TWO (2) decimal places; since we are DIVIDING by "100" (which has "2 (two) zeros") ;

→ 70.9% = [tex] \frac{70.9}{100} [/tex] = 0.709 .
__________________________________________________
3) What percent is equivalent to two-thirds?
__________________________________________________
  → [tex] \frac{x}{100} [/tex] = [tex] \frac{2}{3} [/tex] ;

x = [tex] \frac{2}{3} [/tex]*100 ;

= [tex] \frac{2}{3} [/tex]*[tex] \frac{100}{1} [/tex] ;

= [tex] \frac{2*100}{3*1} [/tex] ;

= [tex] \frac{200}{3} [/tex] ;

= 66[tex] \frac{2}{3} [/tex] ;

→ { 66[tex] \frac{2}{3} [/tex] } / 100 = 66 [tex] \frac{2}{3} [/tex] % ;
or, write as: 66.666666....% ; or, round to:
66.67%
{since: " [tex] \frac{2}{3} [/tex] " = 2 ÷ 3 = 0.66666..." .
______________________________________________

One-eighth, when converted to a percent, is 12.5%. The decimal 0.709 is equivalent to 70.9% when converted to a percent. Two-thirds is roughly equivalent to 66.7% after conversion and rounding.

Converting Fractions and Decimals to Percents

To convert a fraction to a percent, you can either first convert it to a decimal or multiply the fraction straightaway by 100. For one-eighth, we multiply 1/8 by 100 to get 12.5%. So one-eighth as a percent is 12.5%.

To rename 0.709 as a percent, you move the decimal point two places to the right or multiply by 100, which gives us 70.9%. Therefore, 0.709 as a percent is 70.9%.

Lastly, two-thirds is equivalent to the decimal 0.666... (repeating). To turn this into a percent, we again multiply by 100, yielding approximately 66.7%, after rounding.

suppose you earn $7.25 per hour working part-time for a florist. Write and solve an inequality to find how many full hours you must work to earn at least $125

Answers

7.25x > 125 because x equals amount of hours times 7.25 is greater that 125

Let's say t is the amount of time (in hours) it takes to make $125,
with that out of the way, the keyword "at least" makes it so that you can get 125 or more in t hours.
The inequality is $125<=7.25t.
Now you can use the guess and check method, for this example we'll use t=18 and t=17.
7.25(18)=$130.5
7.25(17)=$123.25

Therefore, the answer is 18, because 18 gives you a number greater than or equal to $125

The graph approaches the line y equals negative 1 to the left on the graph.

Answers

When a graph is transformed, it could be translated, reflected, dilated, or rotated. However, no matter what kind of transformation that is, it does not change the nature of the graph. A line would still be a line; a curve would still be a curve. So, that is my basis for my solution. There is no need to graph the problem. You only need to find the equation of g(x) through the two points given: (2,0) and (3,2)

m = Δy/Δx = (2-0)/(3-2) = 2
Use point (2,0) to find b:
y = mx + b
0 = 2(2) + b
b = -4

So, g(x) = 2x - 4

Long division is a technique for dividing two numbers that involves working through the remainder and quotient step-by-step. When dividing a larger number (dividend) by a smaller number (divisor) that is difficult to divide in one step, it is usually utilized.

Until there are no more dividend digits, the procedure entails dividing the dividend by the divisor several times, multiplying the divisor by the quotient gained in each step, removing the product from the partial remainder, and bringing down the next dividend digit.

Sophia needs $47 to go on a field trip. She has saved $11.50. She earns $6.50 per hour cleaning her neighbor's garden, and she earns $5.25 per hour selling cakes at a store. Can Sophia go on the field trip if she works at the garden for 4 hours and at the store for 2 hours?

Answers

47 - 11.50 = $35.50 needs to be earned.

If she works 6 hours:
6.50 x 4 = 26
5.25 x 2 = 10.50

26 + 10.50 = $36.50 how much she would earn by working 6 hours.

when you add the amount of money she would earn for working 6 hours $36.50 plus the money she had already had saved up $11.50 the total amount of money she would have is $48.00

So, yes. She would be able to go on the field trip if she worked at both jobs to 6 hours.

When using an area model, each factor in the multiplication problem is used as a dimension of a rectangle.

Final answer:

Area models can be used to solve multiplication problems by visually representing the multiplication as the area of a rectangle or square. The model is divided into equal-sized sections, with the number of sections representing one factor and the size of each section representing the other factor. The total area of the model gives the product of the two factors.
