The formula for finding the distance traveled, based on speed and time, is

Phoenix [80]

Answer and explanation:

The formula for finding the distance traveled, based on speed and time, is $D=R\times T$

Where, D is distance , R is rate (speed) and T is time

Units must be consistent.

1) Given : If the unit for D is miles and the unit for T is minutes.

To find : What must the units for R be?

Solution :

$R=\frac{D}{T}$

Now we put unit,

$R=\frac{miles}{minutes}$

The unit of R is miles per minute.

2) Given : If a bicyclist rides for 160 minutes at an average speed of 17 miles per hour.

To find : How far was the ride ?

Solution :

Speed R=17 miles per hour

Time T=160 minutes

Convert into hours,

$1\text{ minute}=\frac{1}{60}\text{ hour}$

$160\text{ minute}=\frac{160}{60}\text{ hour}$

$160\text{ minute}=2.67\text{ hour}$

Substitute value in the formula,

$D=R\times T$

$D=17\times 2.67$

$D=45.39\text{ miles}$

The distance is 45.4 miles.

3) Given : A bicyclist ride to cover 12 miles in 1.5 hours.

To find : At what speed must a bicyclist ride ?

Solution :

Distance D=12 miles

Time T=1.5 hour

Substitute value in the formula,

$R=\frac{D}{T}$

$R=\frac{12}{1.5}$

$R=8$

The speed is 8 miles per hour.

The numbers 5, 6, 7, and 8 are randomly arranged to create a four-digit number. What is the probability that the number formed i

myrzilka [38]

Using the arrangements and the probability concept, it is found that there is a 0.75 = 75% probability that the number formed is not divisible by 4.

A probability is the number of desired outcomes divided by the number of total outcomes.

The number of possible arrangements of n elements is given by $A_n = n!$

In this problem, there are 4 elements, hence $n = 4, T = A_4 = 4! = 24$ .

A number is a multiple of 4 if the number composed by it's last 2 digits are multiples of 4.

Hence, the possible options for the last 2 digits are: 56, 68, 76.

For each of them, there are $A_2 = 2! = 2$ options for the first 2 digits, hence, there will be 2 x 3 = 6 multiples of 4.

The other 18 numbers formed are not divisible by 4, hence:

$p = \frac{18}{24} = 0.75$

0.75 = 75% probability that the number formed is not divisible by 4.

How to solve a variable?

amm1812

Answer:

If the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.

Hope this helps :D
