Answer:

C. 28.6units^2, 0.28

Step-by-step explanation:

<em><u>To find the white portion's area, you add 44 and 47, then multiply it by π</u></em>r^2:

44 + 47 = 91

\frac{91}{360}(3.14)(6)^2

A = 28.574   →    A = 28.6

<em><u>There are 7 parts of the circle, and 2 of them are white. So divide 2 by 7:</u></em>

2 ÷ 7 = 0.28

An arc on a circle measures 85°. The measure of the central angle, in radians, is within which range? 0 to StartFraction pi Over
barxatty [35]

Answer:

0 to StartFraction pi Over 2

Step-by-step explanation:

we know that

If the arc on a circle measures 85 degrees, then the measure of the central angle is also 85 degrees too

so

The central angle in degrees is within the range (0,90^o)

Convert to radians

Remember that

\frac{\pi}{2}\ radians=90^o

therefore

the range in radians is (0,\frac{\pi}{2})

0 to StartFraction pi Over 2

The sum of 3 consecutive integers is 60. What is the value of the third integer?
Scorpion4ik [409]

Answer:

x=19

Step-by-step explanation:

The consecutive integers will be x, x+1 and x+2 since consecutive integers have a pattern.

So,  the equation is x+x+1+x+2=60

Solve:

x+x+1+x+2=60

3x+3=60

Subtract 3 on both sides:

3x+3-3=60-3

3x=57

Divide by 3

3x/3=57/3

x=19

42-x=58

or, -x=58-42

with change in side sign also chamges we change sides to make like terms in one side and unlike in amother side.

or, -x= 16

or,x=-16.

therefore x=-16...

<em>Hope</em><em> </em><em>this</em><em> </em><em>helps</em><em> </em><em>you</em><em>.</em>
