Answer:

<em>m<2 = 145</em>

<em>See process below.</em>

Step-by-step explanation:

Lines b and c are parallel.

m<4 = 55 by corresponding angles.

m<3 = 90 since lines a and d are perpendicular.

m<2 = m<3 + m<4  by the exterior angle of a triangle theorem.

m<2 = 90 + 55

m<2 = 145

A number cube is tossed and a spinner is spun. What is the probability of getting a 3 or 4 on the number cube and not getting 8
Rufina [12.5K]

Answer:

7/24

Step-by-step explanation:

Given in the question,

a number cube is tossed and a spinner is spun.

Cube have 6 in numbers

1 2 3 4 5 6

probability of having 3 or 4 = 2/6

                                             = 1/3

                           

Spinners are commonly made with 6, 8, 10 and 12 flat surfaces.

If a spinner has 8 flats then you have a 7/8 chance of not getting an 8.

Probability of getting a 3 or 4 on the number cube and not getting 8

"and" mean multiplication

7/8 x 1/3

7/24

A race car is moving with a velocity of 144 kilometers/hour. The driver applies the brakes, and the car comes to a halt in 12.0
FinnZ [79.3K]
To answer, first, convert the given velocity in km/h to m/s as shown below,
                        (144 km / hr) x (1000 m / 1 km) x (1 hr / 3600 s) = 40 m/s
The acceleration (a) is solved by through the equation,
                                     a = (Vf - Vi) / Δt
where Vf and Vi are final and initial velocities, respectively and Δt is change in time. Substituting the known values,
                                     a = (0 - 40 m/s) / 12 s = -3.3 m/s²
Thus, the answer to this item is letter B.
