Item 4 In a circle with a radius of 36.9 m, an arc is intercepted by a central angle of 8π 5 radians. What is the arc length? Us
leva [86]

Answer:

The arc length is 185.39 meters.

Step-by-step explanation:

The arc length is calculated by the following expression:

\Delta s = \Delta \theta \cdot r

Where:

r - Radius, measured in meters.

\Delta \theta - Central angle, measured in radians.

If r = 36.9\,m and \Delta \theta =\frac{8}{5}\pi\, rad, the arc length, measured in meters, is:

\Delta s = \frac{8}{5}\pi\cdot (36.9\,m)

\Delta s = \frac{8}{5}\cdot (3.14)\cdot (36.9\,m)

\Delta s \approx 185.386\,m

\Delta s \approx 185.39\,m

The arc length is 185.39 meters.

If the mean of the data set is 7 raisins, find the number of raisins in each scoop of Great4U.
Bingel [31]

Step-by-step explanation:

The mean is given as 7. That is the only information given, and it is not enough to determine the number of raisin in each scoop.

Suppose the total number of raisins was given, then the total number of raisins is easily given as (total number of raisins) ÷ (mean)

= (total number of raisins) ÷ 7

Triangle ABC is similar to triangle PQR, as shown below:
dalvyx [7]
Let's see here... well, since the first letter in the ratio is from the first triangle, then, the first one in the equal ratio is going to have to be that as well, and the ratio of c:a wouldn't work, since c was already used. By process of elimination, it's gotta be b:q.

Please show how to solve! 20 Points!<br> 3(x+2)^3/5 +3=27
Lemur [1.5K]

Answer:

x=30

Step-by-step explanation:

3(x+2)^3/5 +3=27

Subtract 3 from each side

3(x+2)^3/5 +3-3=27-3

3(x+2)^3/5 =24

Divide by 3

3/3(x+2)^3/5 =24/3

(x+2)^3/5 =8

Take everything to the 5/3 power to get rid of the exponent on the left side

(x+2)^3/5 ^ 5/3=8 ^ 5/3

Remember that a^b^c = a^ (b*c)

(x+2)^(3/5 * 5/3)=8 ^ 5/3

(x+2)=8 ^ 5/3

Replace 8 with 2^3

(x+2)=2^3 ^ 5/3

Remember that a^b^c = a^ (b*c)

(x+2)=2^(3 * 5/3)

x+2 = 2^5

x+2 = 32

Subtract 2 from each side

x+2-2 = 32-2

x=30
