Answer:

4 miles per hour

Step-by-step explanation:

Total miles = 1/2

Time taken = 1/8

Miles per hour = 1/2 ÷ 1/8

= 1/2 × 8/1

= 8/2

= 4 miles per hour

Bryan’s mile per hour = 4

4 miles per hour

The circumference of a roll of party streamers is 9 inches. The circumference decreases by 2 inches after you use the streamers
leonid [27]
For that case the new circumference is:
 C = 9 - 2
 C = 7 inches
 By definition, the circumference is:
 C = 2 * pi * r
 Where,
 r: radio
 Substituting values:
 7 = 2 * pi * r
 Clearing the radio:
 r = 7 / (2 * pi)
 Then, the diameter is:
 d = 2 * r
 Substituting:
 d = 2 * (7 / (2 * pi))
 d = 2.228169203
 Round to the hundredth:
 d = 2.23 inches
 Answer:
 
The diameter of the roll after the decrease is:
 
d = 2.23 inches

Which relation is a function?
Artemon [7]

Answer:

C

Step-by-step explanation:

What makes a function is if each input or x-value has EXACTLY one output or y-value.

a. is wrong because the x value 1, has both an output of 1 and 4

b. is wrong because -1 is repeated 4 times with all different outputs

c. is correct because each input has exactly one output. None of the x values repeat itself

d. is wrong because -1 has 2 outputs.

so this is what makes a function and what doesn't. Hope this helps!
