Which number produces an irrational number when multiplied by 2/5?

Ganezh [65]

Answer: The correct option is (D) pie.

Step-by-step explanation: We are to select the correct number that produces an irrational number when multiplied by pie.

We know that if one of number is a non-zero rational number, then for the product to be irrational, we must have the other number irrational.

Give number is 2/5, which is rational. So the other number must be irrational.

Out of the given options, first three numbers are rational.

Only the last number pie is irrational. Because, the digits after the decimal are non-repeating and non-terminating.

So, the product will be irrational, if the other number is pie.

Thus, the correct option is (D).

In the collection of beads, StartFraction 4 Over 20 EndFraction are blue. Which model shows the percent of beads that are blue?

jolli1 [7]

Option B model shows the percent of beads that are blue.

Solution:

Fraction of beads blue = $\frac{4}{20}$

To convert it into percent multiply the fraction by 100.

$$\text {Percent of} \ \frac{4}{20}=\frac{4}{20}\times 100\%$

$$=\frac{4\times 100}{20} \%$

Cancel the common factors, we get

= 20%

$$=\frac{20}{100}$

This means total number of boxes 100 and shaded in blue color 20.

Therefore option 2 represents $\frac{20}{100}$ .

Hence option B model shows the percent of beads that are blue.

Write an equation of the line that passes through a pair of points:<br> (-3,1). (-2,-5)

Nat2105 [25]

Answer:

$y=-6x-17$ (B)

Step-by-step explanation:

$y=mx+b\\m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} } = \frac{1--5}{-3--2} = \frac{6}{-1} = -6\\y=-6x+b\\$

Plug in one of the two points for X and Y

(-3,1)

$1=-6(-3)+b\\1=18+b\\b=-17\\\\y=-6x-17$
