How can you subtract fractions with unlike denominators?
Rama09 [41]

Answer:

No, You can't. You have to make their denominators equal!

-\frac{7}{10}

Step-by-step explanation:

So first, you make their denominators equal!

\frac{1*2}{5*2} =\frac{2}{10}=\frac{1}{5}

Multiplying both the numerator and denominator with the same number results in the same fraction, just un-simplified

So, we input it!

\frac{2}{10} -\frac{9}{10} = -\frac{7}{10}

There you go!

Hope you get better at math!(gets wayyyyyyyyyyy...y more complicated later)

Hope this helps!

See Ya!

P.S. Stay Safe!

Which is the graph of f(x) = Square root of x?
natka813 [3]

Answer:

Third option given

Step-by-step explanation:

On a coordinate plane, a parabola opens to the right with a vertex at (0, 0).

use the following x values to plot the associated y values on the x-y plane:

If x = 0,  then y=\sqrt{0}  =0

If x = 1,  then y=\sqrt{1}  =1

If x = 4,  then y=\sqrt{4}  =2

If x = 9,  then y=\sqrt{9}  =3

Join the points and you will find a branch of a parabola opening to the right.

Jesse is playing a game with a number cube with faces numbered 1 through 6. What is the probability of rolling a number that is
lana [24]

Answer:

The probability of rolling a number that is even and a multiple of 3 is \frac{1}{6}

Step-by-step explanation:

The total possible  outcomes of cube = { 1, 2, 3 , 4 , 5 , 6}

Now, let E: Event of getting an even number and a multiple of 3

So, out of all the outcomes, {6) is the ONLY possible favorable outcome.

\textrm{P(E)}  =\frac{\textrm{Number of favorable outcomes }}{\textrm{Total number of outcomes}}

or, P(E) = \frac{1}{6}

Hence, the probability of rolling a number that is even and a multiple of 3 is \frac{1}{6}

A lab at the DeBakey Institute orders 150 rats a week for each of the 52 weeks in the year for experiments that the lab conducts
FromTheMoon [43]

Answer:

a. The expected or average costs for all weekly rat purchases is $20.00

Step-by-step explanation:

a. A mean value of $20.00 means that over a period of 52 weeks, the company can expect to spend $20.00 per week on rat purchases.

b. This is incorrect since individual values don't interfere in the mean. For instance, if half the weeks had a cost of $19.00 and the other half had a cost of $21.00, the mean cost would still be $20.00 even though no particular week had a $20.00 cost

c. Incorrect. The median is the central value in a distribution; the median and the mean are not necessarily the same.

d. Incorrect, same as item b.
