0. For a button to fit through its buttonhole, the hole needs to be the size of the button's diameter. What size buttonhole is n
eeded for a button with a circumference of 7.38 centimeters? (Use the value of 3.14 to represent pi.)
1 answer:
The formula for the circumference of a circle is : C =2 x PI x r
Using this formula and the provided information we can find the diameter:
Circumference is given as 7.38 cm
PI is given as 3.14
So now we have:
7.38 = 2 x 3.14 x r
Multiply 2 and 3.14:
7.38 = 6.28 x r
Divide both sides by 6.28:
r = 7.38 / 6.28
r = 1.17516
Diameter = 2 x r
Diameter = 2. 1.17516
Diameter = 2.35 cm
The button hole needs to be 2.35 cm

Answer:
The box of 10 for $10.88 is better.
Step-by-step explanation:
10.88/10=$1.08
17.62/14=$1.26
I think the answer is 25.5. Although, I don't know how you would have half a bike unless there was a 3 wheel bike which would make the answer 24.
You will earn $128.00 because when you divide $112.00 by 7 you get 16. Then you multply 16 by 8 and get $128.00

Answer:
Step-by-step explanation:
- The speed of the boat in the lake = x
- The speed of the current = 3 km/h
<u>Required equation:</u>
- 54 / (x + 3) + 42 / (x - 3) = 96/x
- 9x(x - 3) + 7x(x + 3) = 16(x + 3)(x - 3)
- 9x² - 27x + 7x² + 21x = 16x² - 144
- 6x = 144
- x = 144/6
- x = 24 km/h
