Answer:

6

Step-by-step explanation:

A regular hexagon has six side and it is rotated counterclockwise about its center.

rotation is 0° < x ≤ 360

it will map on itself at the multiples of the angle = 360 / 6 = 60°

which are 60°, 120°,180°, 240°, 300° and 360°

the number of different angles = 6

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2.4 h, and Car B traveled the dis
S_A_V [24]
Given:
t A = 2.4 h
t B = 4 h
v A = 22 + v B

Solution:
Distance A and distance B is the same, distance could be defined using formula d = v × t
d A = d B
(v A × t A) = (v B × t B)

plug in the numbers
v A × 2.4 = v B × 4
(22 + vB) × 2.4 = 4 vB

remove the parenthesis using distributive property
(22 × 2.4) + (2.4 × vB) = 4vB
52.8 + 2.4vB = 4vB
add like terms
52.8 = 4vB - 2.4vB
52.8 = 1.6vB
52.8/1.6 = vB
vB = 33
the speed of car B is 33 mph

vA = 22 + vB
vA = 22 + 33
vA = 55
the speed of car A is 55 mph

PLEASE HELP!!! What is the slope parallel to 5x + y = 3, please show me step by step, will give the brainliest for this answer.
Andreas93 [3]

Answer:

-5

Step-by-step explanation:

First, put the equation into the form y = mx +b (where m is the slope and b is the y-intercept)

This would look like:

5x + y = 3\\y = -5x + 3

This means the slope is -5.

Parallel lines always have the same slope, so the slope of the parallel line is also -5
