Answer:

144

Step-by-step explanation:

Inscribed Angle = 1/2 Intercepted Arc

72 = 1/2 X

Multiply each side by 2

72*2 = 1/2 x*2

144 =x

The force, F, needed to break a board in a martial arts class varies inversely with the length, L, of the board. If it takes 24

9966 [12]

Answer:

it would take 40 pounds of pressure to break the board.

Step-by-step explanation:

$F = \frac{x}{L}$

Now we plug in the numbers of force and length

$24 =\frac{k}{2.5}$

Now we multiply both sides by 2.5 to get rid of the fraction.

$60=x$

Now we plug in our variation constant

$F=\frac{60}{L}$

So we convert the length of 2.5 feet into inches. This is 18 inches. Since there are 12 inches in one foot, we have that 18 inches is equal to 18 divided by 12.

18÷12=1.5

We get that 18 inches is equal to 1.5 feet

we plug L = 1.5 into our inverse variation equation and solve for F.

$F=\frac{60}{1.5}$

This simplifies to F = 40

Answer:

y = -3/2x + 3

Step-by-step explanation:

First, know that slope-intercept form is y = mx + b. Since our y-intercept is 3, we can plug that in for B, and since the slope goes down 3 and over to the right 2, it is -3/2. So, when everything's plugged in, we get y = -3/2x + 3.

I hope this helped! Please leave Brainliest if it did.

What is the fraction -2 over 3 multiplied by -2 equal?

defon

-2/3 times -2. You change -2 into -2/1 so you can multiply numerator to numerator and denominator to denominator. You will get 4/3 (negatives cancel out)
