A number cube has sides labeled 1 to 6. Gia rolls the number cube. What is the probbillty the she rolls 4?

kotegsom [21]

<span>A cube Has 6 sides.So,n(A)=6={1,2,3,4,5,6} Probability to getting number 4 in a cube is Event A. n(s)=1 Probability of event A that occurs : P(A) = 1/6. P(A)=0.167 Probability of event A that does not occur P(A') = 1 - 0.167 =0.833 Probability to getting number 4 in a cube is 0.167</span>

What is the difference in speed between two cars when one traveled 175 km in 4 hours and the other traveled the same distance in

vovangra [49]

<h3>Given :</h3>

Distance = 175
Time 1 = 4 hours

$\\ \\$

<h3>To find:</h3>

Different between two speeds when distance is same.

$\\ \\$

<h3>Solution:</h3>

<u>Part</u><u> </u><u>1</u><u> </u><u>:</u>

In first part we will find speed 1 in which time is 4 hours

we know:-

$\bigstar \boxed{ \rm speed = \frac{distance}{time} }$

So:-

$\dashrightarrow\sf speed_1 = \dfrac{distance}{time_1}$

$\\ \\$

$\dashrightarrow\sf speed_1 = \dfrac{175}{4}$

$\\ \\$

$\dashrightarrow\bf speed_1 = 43.75 \: km {h}^{ - 1}$

<u>Part 2</u>

In first part we will find speed 2 in which time is 3 hours

Again:

$\bigstar \boxed{ \rm speed = \frac{distance}{time} }$

$\\ \\$

$\dashrightarrow\sf speed_2 = \dfrac{distance}{time_2}$

$\\ \\$

$\dashrightarrow\sf speed_2 = \dfrac{175}{3}$

$\\ \\$

$\dashrightarrow\bf speed_2 = 58.33kmh^{-1}$

$\\ \\$

<u>Part 3</u>

In this part we will find different between speed 1 and speed 2

$\bigstar \boxed{\rm Difference = speed_2 - speed_1}$

$\\ \\$

So :

$\dashrightarrow\sf Difference = speed_2 - speed_1 \\$

$\\ \\$

$\dashrightarrow\sf Difference =58.33 - 43.75\\$

$\\ \\$

$\dashrightarrow\bf Difference =14.58kmh^{-1}\\$

$\\ \\$

$\therefore \underline {\textsf{\textbf{Difference in speed between two cars is \red{14.58km/h}}}}$

May u please help me ill give out the brainly

Eddi Din [679]

Answer:

The answer is B.

Step-by-step explanation:

In order to solve this problem, you need to combine like terms, which in this case, are the x's. So, if you add the numbers with the x's together, you get 3x + 12y. The 12y remains untouched because there are no other terms with the same variable.

Hope this helped,

Philip

Brainliest always appreciated! <3
