49.71666... round to where you need to. I might be wrong. The formula should  be ArcLength = angle / 360 * 2 pi radius so 150/360*(2*pi*19)

Answer: 49.72 feet (approximate to 2 decimal places; using pi = 3.14)

=============================================================

Explanation:

The distance around the entire circle (also known as the circumference) is found by the formula

C = 2*pi*r

with C being the circumference, pi = 3.14 approximately, and r is the radius. The circumference of this circle is approximately C = 119.32 because C = 2*pi*r = 2*3.14*19 = 119.32

---------

The arc length is the shaded darker region of the circle's edge marked by the 150 degree central angle. We only want a portion of the entire distance around the circle. So we take a fraction of the circumference to get (150/360)*C = (150/360)*119.32 = 49.71667 = 49.72 which is approximate to two decimal places.

What is the slope of a line that passes through (-4,-13) and (19,11)?
raketka [301]
We can find the slope from the two given points using the standard formula:
m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}
m=\frac{11-(-13)}{19-(-4)}
m=\frac{24}{23}

what is the probability that a number selected at random from the set {2,3,7,12,15,22,72,108} will be divisible by both 2 and 3?
evablogger [386]
First, look at how many numbers are divisible by 2 and 3. 
12,72, and 108 and are all divisible by both 2 and 3. That makes 3 out of 8 numbers.
Depending on what form you have to put the probability, that makes it 3:8, 3 out of 8, or 37.5% probability.

1. tentukan hasil dari 243⅔?
Vesnalui [34]

Penjelasan langkah demi langkah:

1)

= 243^{\frac{2}{3} }\\= (\sqrt[3]{243})^2\\= 7^2\\= 49

2) √32 +3√18-2√50

= √16*2 +3√9*2-2√25*2

= 4√2 + 3(3√2)-2(5√2)

= 4√2 + 9√2-10√2

= 13√2-10√2

= 3√2

3) 1000 ⅔×64⅙

 = (\sqrt[3]{1000}) ^2 \times (2^6)^{1/6}  \\= 10^2 \times 2\\= 100 \times 2\\= 200

4) 3/4+√2

3/4+\sqrt{2} \\= \frac{3+4\sqrt{2} }{4 }

5) 2√3×√18

= 2√3×√9*2

= 2√3×3√2

= (2*3)(√3*√2)

= 6√6

6) 12/3+√3

= 4+√3

7) √1000—2√40

= 10 -2 (√4*10)

= 10-2(2√10)

= 10 - 4√10

8) 2- ¹+3-¹

= \frac{1}{2} + \frac{1}{3}\\ = \frac{3+2}{6}\\ = \frac{5}{6}

9)

\frac{5}{\sqrt{5} }\\ merasionalisasikan\\= \frac{5}{\sqrt{5} }\times \frac{\sqrt{5} }{\sqrt{5} }\\= \frac{5\sqrt{5} }{\sqrt{25} }\\= \frac{5\sqrt{5} }{5}\\ = \frac{\sqrt{5} }{1}

Jika pernyataannya opsional, penyebutnya adalah 1

10) 2√3×√18

= 2√3×√9*2

= 2√3×3√2

= (2*3)(√3*√2)

= 6√6
