A full circle in radians is 2π, and in degrees it's 360°. I want to convert the 72° to radians:

72° in radians = 72/360 * 2π = 2/5π

The circumference of a full circle is the number of radians times the radius. (ie., 2πr), so the JK part of the circle is:

5* 2/5π simplifies to 2π

Candice and christ run a relay race at recess. Candice runs 1/2 of a lap around the track. Chris runs 1/3 of a lap around the tr
eduard

Answer:

Candice ran 1/6 of a lap further than Chris.

Step-by-step explanation:

we know that

To find out how much further Candice runs than Chris, subtract the distance Chris runs from the distance Candice runs

so

\frac{1}{2}-\frac{1}{3}=\frac{3-2}{6}=\frac{1}{6}\ lap

therefore

Candice ran 1/6 of a lap further than Chris.

Please help me with this math problem.
liraira [26]

If we plug the values, we have

f(2) = 2p+3,\ g(5) = 5+4p

So, we have to solve the following equation:

2p+3 = 5+4p \iff -2p=2 \iff p = -1

So, when we impose f(x) = g(x), knowing the value of p, we have

f(x) = -x+3 = x-4 = g(x)

And so the solution is

-x+3 = x-4 \iff -2x = -7 \iff x = \dfrac{7}{2}

You have to explain why dividing 5/6 is the same as multiplying by 6/5
MArishka [77]
Because it equals to 1 either way. To divide 5/6 by 5/6 you turn a fraction upside down and multiply together. 5/6÷5/6→ 5/6×6/5= 1
