How to change 9.15 to a fraction

1 answer:

3 0

The 1 is in the tenths place and the 5 is in the hundredths place, so we know that the denominator will be 100.
The numerator will be 15, since that is the decimal.

$9 \frac{15}{100}$

To simplify, first find the GCF between 15 and 100.

$15:1,3,5,15 \\ 100:1,2,4,5,10,20,25,50,100 \\ common:1,5 \\ GCF:5$

Now, to get the fully simplified mixed number, divide the numerator and denominator both by the GCF.

$9 \frac{15:5}{100:5} \\ \\ 9 \frac{3}{20}$

To convert the mixed number into an improper fraction, multiply the whole number by the denominator and add it to the numerator, keeping the denominator. This will be your final answer.

$\frac{9*20+3}{20} \\ \\ \frac{180+3}{20} \\ \\ \frac{183}{20}$

(will give brainliest) find the value of x

Sedaia [141]

Answer:

x = 180 - [(180 - 3x) + (180 - 2x)]

Step-by-step explanation:

Start off by finding the angles of the triangle

Angle F = 180 - 3x

The angle across from I (which I will call I) = 180 - 2x

Angle G = 180 - (F + I)

Now that we know what G is, we know what x is because the Alternate Exterior Angles Theorem states that if a pair of parallel lines are cut by a transversal, then the alternate exterior angles are congruent. So pretty much X = G

Therefore x = 180 - (F + I) or otherwise said as:

x = 180 - [(180 - 3x) + (180 - 2x)]

I hope this is helpful :)

Can someone answer this fast!!!

Otrada [13]

Answer:

= $6\sqrt{3}$

Step-by-step explanation:

This triangle is the same as a right triangle rotated around.

Pythagorean Theorem applies to this (because it's a right triangle)

$a^{2} +b^{2} =c^{2}$

$36+b^{2} =144$

$144-36=108\\b^{2} = 108\\\sqrt{108} = 10.39\\ = \sqrt{b^{2} } \\b=10.39$

x=10.39

It has been found that women are excluded from social events with coworkers. One study at Company X, found that women only recei

Natasha2012 [34]

Answer:

Option C is correct.

The p-value in this case is the probability of getting data like that observed or more extreme (i.e., getting an observed invitation rate of 33% or higher) assuming that;

The social strategies did not increase the rate of invitations for female colleagues.

Step-by-step explanation:

The p-value is actually defined as the probability of obtaining results as extreme as the observed results in the statistical analysis provided that the null hypothesis is true.

The standing condition for the p-value definition is the assumption that the null hypothesis is true, then it is the probability of getting the extreme result (usually not due to just random chance), that is usually observed, being tested for and contained in the alternative hypothesis.

Normally, in hypothesis testing, especially one comparing two sets of data, the null hypothesis plays the devil's advocate and usually takes the form of the opposite of the theory to be tested. It usually contains the signs =, ≤ and ≥ depending on the directions of the test. It usually maintains that, with random chance responsible for the outcome or results of any experimental study/hypothesis testing, its statement is true.

The alternative hypothesis usually confirms the theory being tested by the experimental setup. It usually contains the signs ≠, < and > depending on the directions of the test. It usually maintains that significant factors other than random chance, affect the outcome or results of the experimental study/hypothesis testing and result in its own statement.

Since this test aimed to test whether the rate of invitation of women to outside work events after using the social strategies, the null hypothesis for the question would be that there is no significant difference in the rate of invitation of the women after using the social strategies while the alternative hypothesis would be that the social strategies worked and the rate invitation of women to outside of work events increased.

So, the null hypothesis that we need to assume was true in the p-value definition is that; the social strategies did not increase the rate of invitations for female colleagues.

This is option C!

Hope this Helps!!!

Answer:

200.96 ft²

Step-by-step explanation:

The question is on surface area of a closed cylinder

Formulae= SA=2 ×pi× r² + 2×pi×r×h

Where pi=3.14

SA= 2×3.14×2² + 2×3.14×2×14

SA=25.12+175.84

SA=200.96 ft²

Desde cierto paradero se transportan 300 pasajeros en

Misha Larkins [42]

Se necesitan 10 micros.

En principio, sabemos que 300 pasajeros pueden transportarse en 4 microbuses.

Entonces, el numero de pasajeros que va por cada micro será el cociente entre el numero de pasajeros y el numero de micros:

N = 300/4 = 75

<em>Queremos responder:</em>

¿Cuántos micros se deben aumentar para que por cada 3 micros se transporten 90 pasajeros?

Definamos X como el numero de grupos de 3 micros que tendriamos en esta situación.

Entonces 300 sobre X, debe ser igual a 90 (el numero de pasajeros que va en cada grupo de 3 micros)

300/X = 90

300 = 90*X

300/90 = X = 3.33...

Notar que el número total de micros sera 3 veces X:

3*X = 3*3.33.... = 10

Se necesitan 10 micros.
