1/3 ÷ 2 = ? in fractions

2 answers:

7 0

2 is also the fraction 2/1, so the question is:
$\frac{1}{3} / \frac{2}{1}$
when dividing fractions, you take the second fraction flip the top number (numerator) with the lower number (denominator) and then change the division sign to multiplication:
$\frac{1}{3} * \frac{1}{2}$
= $\frac{1}{6}$ or one sixth

1/3 ÷ 2 =

1/3 x 2/1. you do this by doing the reciprocal of 2, and then you do KCF ( keep, change, flip,)

keep 1/3 change ÷ to × and flip 2/1 to 1/2.

1/3 x 1/2 = 1/6.

hopefully this helps you

No it isn't.

Explanation:

x/y * y = (y-6) * y

x = y^2 - 6y

A function gives just one y for every x

In this case there will always be 2 y's for every x

Example:

y can be

y = 6

y =−6

(0,-6) & (0,6)

What is the radius of a sector of a circle with the central angle of measure 45 and whose area is 9/8 pi cm^2

larisa86 [58]

The radius of the sector of the circle with the given area is: B. 3.

<h3>What is the Area of a Sector?</h3>

Area of sector of a circle = ∅/360 × πr².

Given the following:

Area of sector = 9/8 π cm².

∅ = 45 degrees

Plug in the values into the formula

9/8π = 45/360 × πr²

1.125 = 0.125 × r²

1.125/0.125 = r²

9 = r²

r = 3 cm

Final exam scores are normally distributed with a mean of 74 and a standard deviation of 6. Approximately, what percentage of fi

notka56 [123]

Answer:

81.86%

Step-by-step explanation:

We have been given that final exam scores are normally distributed with a mean of 74 and a standard deviation of 6.

First of all we will find z-score using z-score formula.

$z=\frac{x-\mu}{\sigma}$

$z=\frac{68-74}{6}$

$z=\frac{-6}{6}=-1$

Now let us find z-score for 86.

$z=\frac{86-74}{6}$

$z=\frac{12}{6}=2$

Now we will find P(-1<Z) which is probability that a random score would be greater than 68. We will find P(2>Z) which is probability that a random score would be less than 86.

Using normal distribution table we will get,

$P(-1$

$P(2>Z)=.97725$

We will use formula $P(a$ to find the probability to find that a normal variable lies between two values.

Upon substituting our given values in above formula we will get,

$P(-1$

Upon converting 0.81859 to percentage we will get

$0.81859*100=81.859\approx 81.86$

Therefore, 81.86% of final exam score will be between 68 and 86.

A baseball field is in the shape of a square. The

lina2011 [118]

Since the distance in between each plate is 90ft. We know from home to 1st is 90ft. To get to 2nd from first is also 90ft. So 90 + 90 is 180ft.

Now this question is weird because it could be asking how far would a baseball player would have to run to get to 1st then 2nd

Or

Could be asking the distance from Home to 2nd without going to 1st. So just a straight line from home to 2nd.

If that’s the case we need to use the Pythagorean theorem

Our setup would be 90^2 + 90^2 = c^2
Adding A and B will get us 16200. Now we need to divide to get to the other side. But C is squared. So we need to Square root 16200. Which is 127.28ft.
