Which expression is equivalent to sqrt10/4sqrt8

Mathematics
2 answers:
Irina-Kira [14]3 years ago
8 0

Answer:

Step-by-step explanation:

Since it's a division we need to look for a common factor to cancel

so first we try to break the numbers to there prime factors

\frac{\sqrt{10} }{4\sqrt{8} } = \frac{\sqrt{2.5} }{4\sqrt{2.2.2} }

So , now we try to factors that are common in top and bottom

= \frac{\sqrt{2} \sqrt{5}}{4\sqrt{2}\sqrt{4} }

common factor is sqrt 2 so lets cancel it

we get

\frac{\sqrt{5} }{4\sqrt{4} }

\frac{\sqrt{5} }{8}

We can break √10 into √2 • √5, and √8 into √2 • √4, or, simplifying √4 to 2, 2 • √2. Our expression now becomes

(√2 • √5) / (4 • 2 • √2)

Cancelling the √2 in the numerator and denominator gets us

√5/(4 • 2), or √5/8.

Write an equation of the line with the given properties. Your answer should be written in standard form.
Vanyuwa [196]

Given:

The slope of the line is m=0.

The line passes through the point P(-9,-3).

To find:

The equation of the line in standard form.

Solution:

Standard form of a line is:

Ax+By=C

The slope intercept form of the line is

y-y_1=m(x-x_1)

Where, m is the slope and (x_1,y_1) is the point on the line.

It is given that the slope of the line is 3 and it passes through the point (-9,-3), so the equation of the line is

y-(-3)=0(x-(-9))

y+3=0

y=-3

Therefore, the standard form of the given line is y=-3.

Can someone help me asap

Answer:

Option Y is correct.

Step-by-step explanation:

We are given the table representing the relation between new students and returning students for difference classes.

It is required to form the relative frequency table for the given situation.

So, relative frequency table is obtained by dividing the valued by the total number of values in the data set.

<em>Thus, we will get the relative frequency table by dividing the given table values by 500.</em>

Hence, we will get the following table,

                          New Students               Returning Students           Total

10th                         0.01                                   0.34                             0.35

11th                          0.006                                0.324                           0.33

12th                         0.004                                0.316                            0.32

Total                        0.02                                  0.98                                1

Thus, option Y is correct.
