Answer:

24) -1

25) indefinite/infinite

26) indefinite/infinite

27) 7/3

Step-by-step explanation:

24)

$\frac{4-2}{-3+1}\\= 2/-2\\= -1\\$

25)

$\frac{10+2}{5-5}\\\\= \frac{12}{0}$

= indefinite/infinite

26)

indefinite/infinite

27)

$\frac{16-9}{11-8}\\\\= \frac{7}{3}\\$

In the diagram of movie theater seats, the incline of the floor, f, is parallel to the seats, s.

weqwewe [10]

Answer:

16. x = 40

17. y = 15

Step-by-step explanation:

16. Given that f is parallel to s, therefore by the corresponding theorem and linear pair theorem, <1 + 3x = 180°

60° + 3x = 180° (substitution)

3x = 180° - 60° (Subtraction property of equality)

3x = 120°

x = 120/3 (division property of equality)

x = 40

17. Since f and s are parallel, therefore,

m<1 = (5y - 7)° (alternate interior angles are congruent)

68° = 5y - 7 (substitution)

68 + 7 = 5y (addition property of equality)

75 = 5y

75/5 = y (division property of equality)

15 = y

What is the solution to the system of equations

FromTheMoon [43]

Answer:

(0,3)

Step-by-step explanation:

solve for 2y

-X-2y= -6

2y=6+2x

substitute the given value of 2y into the equation -x-2y=-6

-x-(6+3x)= -6

solve for x

x=0

substitute the given value of X into the equation 2y=6+3x

2y=6+3×0

solve for y

y=3

the solution is (0,3)

Please Help? A circle has an arc length of 5π in. The central angle for this arc measures π/3 radians. What is the area of the a

Zielflug [23.3K]

Answer:

The area of the associated sector is $\frac{25}{24}\pi \ in^{2}$

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The circumference of a circle is equal to

$C=2\pi r$

we have

$C=5\pi\ in$

substitute and solve for r

$5\pi=2\pi r$

$r=2.5\ in$

step 2

Find the area of the circle

we know that

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=2.5\ in$

substitute

$A=\pi (2.5^{2})=6.25\pi\ in^{2}$

step 3

Find the area of the associated sector

we know that

$2\pi\ radians$ subtends the complete circle of area $6.25\pi\ in^{2}$

by proportion

Find the area of a sector with a central angle of $\pi/3\ radians$

$\frac{6.25\pi }{2\pi} =\frac{x}{\pi/3}\\x=6.25*(\pi/3)/2\\ \\x=\frac{25}{24}\pi \ in^{2}$
