FASTTT HURRYYYY PLEASEEEEEE The pair of figures is similar. Find the missing side.

If a central angle of measure 30° is subtended by a circular arc of length 6 meters, as is illustrated below, how many meters in

Nana76 [90]

30 degrees = pi/6 radians
Arc Length = (radius)(angle in radians)
6 = (radius)(pi/6)
radius = 36/pi or approx. 11.5 m

Vsevolod [243]

Corrected Question

Below is data collected from a random sample of 80 students regarding their fitness habits. If the entire school has 600 students, then what is a reasonable estimate for the number of students who consider themselves to have an average fitness habits.

Answer:

(D)330

Step-by-step explanation:

Out of a random sample of 80 students

44 considered themselves to have AVERAGE fitness habits.

Relative Frequency of Students with average fitness habits=44/80

Therefore, out of the total population of 600 students

Expected Number of Students with average fitness habits

=Relative Frequency of Students with average fitness habits X Total Population

$=\dfrac{44}{80}X600\\\\ =330$

The correct option is D.

What is the equation of the line that is parallel to the line y=-1/3x+4 and passes through the point (6,5)?

natulia [17]

Parallel lines have the same slope. The slope of y = -1/3 x + 4 is -1/3.

The equation is

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

y = -1/3 x -1/3 (- 6) + 5 = -1/3 x + 2 + 5 = -1/3 + 7

The equation is: y = - 1/3 x + 7

y = -1/3 x

Skylar owns a trucking company. For every truck that goes out, Skylar must pay the driver $11 per hour of driving and also has a

jeyben [28]

Answer:

The set of needed equations is

h = 30 m

11 m + 3 h = 909 where

the driver drove for m hours.

h : distance covered in m hours

Step-by-step explanation:

Here, according to the question:

The per hour rate of driver = $11

The gas maintenance expense = $3 per mile.

The total distance covered by drives is 30 miles per hour.

The total expenses paid to driver = $909

Now, let us assume the driver drove for m hours.

The average speed of driver was 30 miles / hour

⇒ Driver covers 30 miles in 1 hour

SO, distance covered in m hours = h = m x 30 = 30 m

or, h = 30 m

So,according to the question, the total amount paid :

Charges of m hours driving + maintenance charges for h miles

= 11 m + 3( h)

or, 11 m + 3 h = $909

Hence the set of needed equations is

h = 30 m

11 m + 3 h = 909
