Under the assumption of <em>uniform</em> motion, the traveller will travel a distance of 20 feet before slowing down the vehicle to less than 40 miles per second.

<h3>How to calculate the distance taken by traveler before braking</h3>

According to this question, the vehicle travels at <em>constant</em> velocity before the traveler hit the brakes. The distance <em>traveled</em> (s), in feet, is equal to the product of velocity (v), in feet per second, and time (t), in seconds:

s = v · t     (1)

If we know that v = 40 ft/s and t = 0.5 s, then the traveled distance of the vehicle is:

s = (40 ft/s) · (0.5 s)

s = 20 ft

Under the assumption of <em>uniform</em> motion, the traveller will travel a distance of 20 feet before slowing down the vehicle to less than 40 miles per second.

A party rental company has chairs and tables for rent. The total cost to rent 3 chairs and 5 tables is $52. The total cost to re
riadik2000 [5.3K]

Answer:

The cost for 1 chair is $2.75 and the cost for 1 table is $8.75

Step-by-step explanation:

Use the elimination method of linear equations to find your answer.

Our equations for this problem are:

3c+5t=52 and 9c+7t=86

1. Multiply the entire first equation by -3.

-3(3c+5t=52)

2. Simplify the equation from above:

-9c-15t=-156

3. Stack the two equations on top of each other and add/subtract:

-9c-15t=-156

9c+7t=86

4. You should be left with -8t=-70. Simplify this to find the value of t:

t=8.75

5. Plug the value of t into any of the original equations and solve for c.

3c+5(8.75)=52

6. Simplify the equation above:

3c+43.75=52

7. Subtract 43.75 from both sides of the equation:

3c=8.25

8. Divide both sides by 3 to get your c value:

c=2.75

sam rolls 3 standard fair dice. that probability that the three numbers rolled on the dice are the sides of a triangle is , wher
mart [117]

The required probability for three numbers rolled on the dice are the sides of a triangle is 31/36.

<h3>What is probability?</h3>

The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability.

Here,

When three dice are rolled, there are 63=216 possible outcomes, or triplets (x, y, z).

Once more, in a triangle, any two sides added together are larger than the third side, or (x+y)>z.

As a result, 186 outcomes or triplets are possible and satisfy this property.

Hence, the required probability is 186/216=31/36.

The required probability is 31/36 for three dice rolls to produce triangle sides.
