If the radius of a circle with center 0 is 15.5, and the measure of angle AOB is 90, what is the length of arc AB?

Mathematics

The circumference of the circle is found using the formula C = 2 PI r

Circumference = 2 *PI * 15.5 = 31pi

The angle is 90 degrees, which is 1/4 of a complete circle ( 360 degrees).

The arc length would be 1/4 of the circumference:

Arc length = 31pi / 4 = 7.75PI

Wich equation gives the number of 1/3 inches that are in 5/6 inches

Hello from MrBillDoesMath!

Answer:

(1/3) x = (5/6)


Discussion:

I think you are asking for this equation:

(1/3) x = (5/6) =>            multiply both sides by 3

(1/3) 3 x = (5/6) 3 =>      as (1/3) *3 = 1

x = 5*3/6

x= 15/6

x = 5/2 = 2.5

Thank you,

MrB

Rose blew h bubbles in two hours. which algebraic expression shows how many bubbles she blew in one minute?
Inessa [10]
\frac{hbubbles}{2hr} =   \frac{hbubbles}{120min} \frac{/120}{/120} =  \frac{hbubbles/120}{1min}

She blew h/120 bubbles in 1 minute.
