Find the value of x. Select one: a. 2.3 inches b. 3.3 inches c. 4.1 inches d. 6.1 inches
spayn [35]

Answer:

c 4.1 inches

Step-by-step explanation:

The circumference of a circle is given by

C = 2*pi*r

The sector is only 78 degrees

Take the fraction of a circle  and multiply by the circumference to find the length x

x = C* 78/360

  = 2 * pi *r * 78/360

  = 2 * pi *3 * 78/360

Using 3.14 for pi

  = 4.082

Rounding to the nearest tenth

x = 4.1 inches

the bus bound for northtown departs every 15 minutes and the bus for eastown departs every 18 minutes from the central station.
USPshnik [31]

Considering the least common factor of 15 and 18, it is found that they will depart from the central station at the same time at 11 AM.

<h3>How to find the time it takes for periodic events to repeat at the same time?</h3>

To find the time that passes between the events happening at the same time, we need to find the least common multiple of the periods.

In this problem, the periods are of 15 and 18, hence their lcm is found as follows:

15 - 18|2

15 - 9|3

5 - 3|3

5 - 1|5

1 - 1

Hence:

lcm(15,18) = 2 x 3 x 3 x 5 = 90 minutes.

They will depart from the central station at the same time in 90 minutes from 9:30 AM, hence at 11 AM.

If x = -3, y = 5 and z = -2, evaluate the following:<br>help plsssss<br><br><br>note giving brilst​
VARVARA [1.3K]

Answer:

3) x^2-yz/z^2

x = -3, y = 5 and z = -2 plug in these values

-3^2 -5(-2) /-2^2

= -1/4

decimal form: -0.25

4) x^2+y^2+z^2/xyz

x = -3, y = 5 and z = -2 plug in these values

-3^2+5^2+-2^2/-3*5*-2

= 2/5

decimal form: 0.4

5) x+y/z + y+z/x

x = -3, y = 5 and z = -2 plug in these values

(-3+5/-2)+(5+(-2)/-3)

= -2

6) 2x+y-z/x-3y+z

x = -3, y = 5 and z = -2 plug in these values

2(-3)+5-(-2)/-3-3(5)+(-2)

= -1/20

decimal form: -0.05
