What is the area of the shaded sector?

Mathematics
1 answer:
nadezda [96]3 years ago
4 0

Answer:

C

Step-by-step explanation:

The central angle is equal to the arc that subtends it, that is 54°

area of sector = area of circle × fraction of circle

A = πr² × \frac{54}{360}

   = π × 10² × \frac{3}{20}

   = 100π × \frac{3}{20} ( cancel 20 and 100 )

   = 5π × 3

   = 15π cm² → C

HELP PLEASE! 50 POINTS AND WILL MARK BRAINLIEST.
alex41 [277]

Answer:

a) independent = hours

   dependent = wages

b ) W = 10 + 5h

c)27.50

Step-by-step explanation:

The independent variable is the one that you change which is the number of hours that it takes

The dependent variable is the variable that changes based on the independent variable.  The wages depends on the hour worked so the wages are the independent variable

The wages equal the fixed cost plus the hourly rate times the number of hours  where W is the wages and h is the number of hours

W = 10 + 5h

W = 10 + 5( 3.5)

    = 10 + 17.5

    = 27.5

Write the equation of the line that passes through (-4, 8) and is parallel to the line that passes through (2, 1) and (-2, -1).
stealth61 [152]

Answer:

Step-by-step explanation:

(2,1), (-2,-1)

slope(m) = (-1-1) / (-2 - 2) = -2/-4 = 1/2

parallel lines will have the same slope

y = mx + b

slope(m) = 1/2

(-4,8)...x = -4 and y = 8

now sub and find b, the y int

8 = 1/2(-4) + b

8 = -2 + b

8 + 2 = b

10 = b

so ur equation is : y = 1/2x + 10 <==
