On the unit circle, an arc of length 2 subtends an angle, β. What is the radian measure of β?

Answers

Answer:

[tex](d)\ \beta = 2\ rad[/tex]

Step-by-step explanation:

Given

[tex]L =2[/tex] -- length of the arc

[tex]r = 1[/tex] --- radius of a unit circle

[tex]\beta =[/tex] the subtended angle

Required

Find [tex]\beta[/tex]

The length of an arc is:

[tex]L = r * \beta[/tex]

This gives:

[tex]2 = 1 * \beta[/tex]

[tex]2 = \beta[/tex]

Make [tex]\bets[/tex][tex]\beta[/tex] the subject

[tex]\beta = 2[/tex]

Hence:

[tex]\beta = 2\ rad[/tex]

A sweater is marked down from $25 to $19. What is the percent of change?

Answers

hi

25X = 19

    X= 19/25

    X = 0.76

so new price is  0.76 % of former price. So it's has been reduce of  24 %  

let's check :    25 * (1-24/100 ) =  25 * 0.76 = 19

The sweater is marked down by 76%

Which expression has a greater value, 3/8 x 5:6 or 3/8 divided by 5/6? Explain

Answers

Answer:

3/8 divided by 5/6

Step-by-step explanation:

To divide a fraction by a fraction, you multiply the first fraction by the reciprocal (aka the fraction flipped upside down, in this case the reciprocal of 5/6 is 6/5). Since 6/5 is greater than 5/6, 3/8 divided by 5/6 is greater than 3/8 times 5/6.

Answer:

[tex]\frac{3}{8}[/tex] ÷ [tex]\frac{5}{6}[/tex]

Step-by-step explanation:

[tex]\frac{15}{64}[/tex] is 0.234375

[tex]\frac{9}{20}[/tex] is 0.45

0.234375 < 0.45

since 72 isn't a multiple of ten we can round it down to 70, then do

70/10=7

since we still have two teeth, we can put them in their own box so

Explanation:

turn 5/11 into a decimal: 0.45 which is LESS than 0.50 (0.5).

Answer:

<

Step-by-step explanation:

When comparing fractions and decimals/fractions and percentages/decimals and percentages, it's always good to convert them to have the same type on either side. However, you don't really need to with this problem.

Here's a trick: the larger the denominator is in a fraction, the smaller the value of the fraction is. If the fraction on the left were 5/10, then we know that it would be equal to 0.5 (you can convert either one). Now, since the denominator of the fraction is one greater than 10, we know that the fraction's value is just a little bit less than 5/10. This makes the fraction less than 0.5.

I hope it made sense. Brainliest would be cool but no worries.

What is the surface area of a right circular cylindrical oil can, if the radius of its base is 4 inches and its height is 11 inches? for 25 points

Answers

Step-by-step explanation:

Given

Radius (r) = 4 inches

height (h) = 11 inches

Total surface area of cylindrical oil can is

= 2πr ( r + h)

= 2 * 22 / 7 * 4 ( 4 + 11)

= 2 * 22/7 * 4 * 15

= 377.14 inches ²

If the radius of a right circular cylindrical oil can base is 4 inches and its height is 11 inches, then the surface area of that right circular cylindrical oil can is 376.99 square inches.

What is the surface area of a right circular cylindrical figure?

Let b and h be the radius of the base and height of a right circular cylindrical figure respectively. Then the surface area of this right circular cylindrical figure is 2πb(b + h).

How to solve this problem?

Given that the radius of the base of the can is 4 inches.

The height of the can is 11 inches.

Then the surface area of the can = 2π * 4(4 + 11) = 8π(15) = 120π = 376.99 square inches

Therefore, If the radius of a right circular cylindrical oil can base is 4 inches and its height is 11 inches, then the surface area of that right circular cylindrical oil can is 376.99 square inches.

To compute the square of the length of a sloped side, you need to sum the squares of the rise and the run. For example, the square of the length of 'a' in triangle F is ...

  a² = rise² + run² = 1² +2² = 1 +4 = 5

__

Additional comment

When computing the slopes of the various triangle sides, you need to pay attention to the sign of the "rise" for a positive "run."

For the distance purpose here, the rise and run are squared, so their signs are irrelevant. You can treat them all as positive numbers.
