Answer:
The length of the arc is 1.6 cm
Step-by-step explanation:
To find the value of the length of the arc, we use the length of arc formula
Mathematically, this is;
theta/360 * 2 * pi * r
where theta is the central angle
In this case pi/4 = 180/4 = 45 degrees
r = 2 cm
So the measure of the length of the arc will be;
L = 45/360 * 2 * 22/7 * 2
= 1/8 * 4 * 22/7
= 22/7 * 1/2 = 11/7 = 1.57 cm which is approximately 1.6 cm
Answer:
10 hours
Step-by-step explanation:
f(h) = 15h + 75 = 225
subtracting 75 from both sides and simplifying:
15h +75-75 = 225-75 =150
15h = 150
Dividing both sides by 15:
15h/15 = 150/15
h = 10 hours
Answer:
a. She will have 30 sixths after cutting all the ribbons.
b. 6 inches.
Step-by-step explanation:
a. You know that the lenght of each piece of ribbon is 1 yard.
She cuts each ribbon into sixths, then the lenght of each one of them is:
So:
Since Faye has 5 pieces of ribbon, after cutting all the ribbons she will have:
She will have 30 sixths after cutting all the ribbons.
b. You need make the conversion from yards to inches.
Knowing that 
, you get:
They are equivalent to each other
