We round up or down depending on the value of the next
digit.

If the tenths place digit is less than 5, round down.

If the tenths place digit is greater than or equal to 5, we
would round up.

62.83 rounded to the nearest whole unit is 63.

Hope I helped!

62.83 rounded to the nearest whole unit is 63. 

If the decimal number is less than .5, it gets rounded down. If it's above .5 (i.e. .83) then it gets rounded up.

Suppose that circles R and S have a central angle measuring 80°. Additionally, the measure of the sector for circle R is
riadik2000 [5.3K]
The correct answer is B) 9 m.

The measure of the sector of circle R is 32π/9 m.  The measure of the central angle is 80°.  This means that the sector is 80/360 = 2/9 of the circle.  The area of a circle is given by A=πr², so the area of the sector is A=2/9πr².  To verify this, 2/9π(4²) = 2/9π(16) = 32π/9.

Using this same formula for circle S, we will work backward to find the radius:

18π = 2/9πr²

Multiply both sides by 9:
18*9π = 2πr²
162π = 2πr²

Divide both sides by 2π:
162π/2π = 2πr²/2π
81 = r²

Take the square root of both sides:
√81 = √r² 
9 = r

Answer:

9 and 18

Step-by-step explanation:

2x and x are the numbers

1/x-1/2x=1/18

2/2x-1/2x=1/18

1/2x=1/18

2x=18X=9,

2x=18

The two integers are 9 and 18

A square room has a tiled floor with 81 square tiles. How many tiles are along an edge of the room?
Strike441 [17]
As there are 81 tiles total, that makes your area 81. Being a square, that makes your area equation A=s^2. As you need a side, this makes your equation s=√A. Plugging in 81 as A, we get s=√81=9, so an edge has 9 tiles.

brad converted 5/11 to a decimal, and his result was repeating decimal. does this mean that the value is rational or irrational?
Alina [70]

Answer: It means the value is rational

Step-by-step explanation:

Repeating decimals can be converted to fractions and rational numbers are numbers that can be expressed as a fraction  but irrational numbers cannot be expressed as a fraction and neither does it terminate or repeat.
