What is 30/7 is a mixed number

Answers

30/7 is an improper fraction, to find its equivalent as a mixed number, we need to find out how many times the denominator, 7, can go into the numerator.....

30/7=4 r2

7 goes into 30 4 times with a remainder of 2

30/7 becomes 4 2/7

Answer= 4 2/7

4 2/7
30/7 is an improper fraction,in order to turn it into a mixed number,you must divide the denominator by the numerator.after you divide,there is a quotient,
the quotient is the whole number,to get the numerator,the reminder of a division problem is the numerator,for the denominator,it stays the same.To check your answer,you must multiply the denominator by the the number and than add it to the numerator.

If the terminal ray of β lies in the fourth quadrant and sin (β) = -√3/3 determine cos(β) in simplest form.

Answers

Answer:

$cos(\beta)=(√(6))/(3)}$

Step-by-step explanation:

we know that

If the terminal ray of β lies in the fourth quadrant

then

sin (β) is negative and cos (β) is positive

Remember the trigonometric identity

$sin^2(\beta)+cos^2(\beta)=1$

we have

$sin(\beta)=-(√(3))/(3)$

substitute

$(-(√(3))/(3))^2+cos^2(\beta)=1$

$(3)/(9)+cos^2(\beta)=1$

$cos^2(\beta)=1-(3)/(9)$

$cos^2(\beta)=(6)/(9)$

apply root square both sides

$cos(\beta)=(√(6))/(3)}$

You drop a pencil out of window that is 20ft above the ground. Use the formula V^2=64s, where V is speed and s is the distance fallen, to calculate the speed the pencil is traveling when it hits the ground.

Answers

first you substitute in the values so you have
V^2=(64)20
then you just simplify it
V^2=1280
V=the square root of 1280
V= about 35.7770876
or
V=the square root of 256 times the square root of 5
V=16 times the square root of 5

also V would typically be called velocity. it's very similar to speed but it is just easier to remember because it starts with a V

Final answer:

Substituting the distance of 20ft (converted to approximately 6.096 meters) into the equation V^2=64s, we calculate that the pencil would hit the ground with a speed of approximately 31.4 m/s.

Explanation:

In this physics problem, we utilize the formula V^2=64s, which connects the speed (V) and the distance traveled (s). The step we are interested in involves substituting known values into our equation. Given that s

is an altitude of 20ft (which we convert to approximately 6.096 meters for consistency in units), we substitute this into our equation and solve for V. This yields V = √(64*6.096). By carrying out this square root, we determine that the pencil hits the ground at approximately 31.4 m/s.

Michael, Jonathan and two of their friends each ride their bikes to school. If they have an equally-likely chance of arriving first, what is the probability that Jonathan will arrive first and Michael will arrive second?

Answers

The probability that Jonathan will arrive first and Michael will arrive second in their bikes to school is P ( A ) = 1/12

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability that Jonathan will arrive first and Michael will arrive second in their bikes to school is P ( A )

Now , the number of people = 4

So , the probability of each person to reach the school first = ( 1/4 )

And , the probability that the second person to reach second = ( 1/3 )

So , probability that Jonathan will arrive first and Michael will arrive second in their bikes to school is P ( A ) = ( 1/4 ) ( 1/3 )

P ( A ) = 1/12

Hence , the probability is P ( A ) = 1/12

Answer:

1/12

Step-by-step explanation:

Jonathan has 1/4 chance and so if Jonathan is already there, there are only 3 people left. 1/4*1/3 is 1/12.
