The radius of a circle is 2 feet. What is the length of a 135° arc?
Over [174]

Answer: length of arc = 4.71 feet

Step-by-step explanation:

An arc is a portion of the circumference of a circle. The formula for determining the length of an arc is expressed as

Length of arc = θ/360 × 2πr

Where

θ represents the central angle.

r represents the radius of the circle.

π is a constant whose value is 3.14

From the information given,

Radius, r = 2 feet

θ = 135 degrees

Therefore,

Length of arc = 135/360 × 2 × 3.14 × 2 = 4.71 feet

In the expression 2(4x + 6) = 78, what is the number you divide by at the end to get the answer?
Ilya [14]

Answer:

8

Step-by-step explanation:

first we will just solve the expression 2(4x +6)=78

1. use destributive property with 2(4x + 6)

2*4x=8x

2*6=12

(8x+12)=78

2. now that the expression is simplified down we will subtract 6 by 6 to isolate it  

6-6+=0

78-6=72

3. now we can divide 8x by 8 also divide 78 by 8

8x/8=0

78/8= 9.75

11111nata11111 [884]

The copy machine makes 105 copies per minutes.

Step-by-step explanation:

Given,

Copies printed by photocopy machine = 735

Time taken by machine = 7 minutes

To find the unit rate in terms of minutes, we will divide the copies printed by machine by the time taken.

Copies printed in one minute = \frac{735}{7}

Copies printed in one minute = 105 copies

The copy machine makes 105 copies per minutes.

Keywords: unit rate, division
