In a plane, if one line has an undefined slope and another line has a slope of zero, what can you conclude

Answer:

The lines are perpendicular

Step-by-step explanation:

Because an undefined slope is just a vertical line, and a line with a slope of zero is just a vertical line. A vertical line and a horizontal line are perpendicular.

Answer:

You can conclude that the lines are perpendicular, and will cross at exactly one point.

Step-by-step explanation: If one line has a zero slope, and the other's slope is undefined, that means one line is exactly vertical, and the other is exactly horizontal. This means that they will cross at exactly one point, and are perpendicular.

How many digits are written when 1000 to the power of 2015 is expressed as a numeral?

PtichkaEL [24]

Answer: There are 6046 digits will be written on expansion upto 2015th power.

Step-by-step explanation:

Since we have given that

$1000^{2015}$

We have to find the number of digits ,

So,

$1000^{2015}\\\\=(10^3)^{2015}\\\\=10^{6045}$

Since we know that

$10^n\text{ has n+1 number of digits }$

so,

$10^{6045}\text{ has 6046 number of digits }$

Hence, there are 6046 digits will be written on expansion upto 2015th power.

By what percent will a fraction decrease if its numerator is decreased by 50% and its denominator is decreased by 25%?

ioda

Answer:

The fraction will decrease $33.33\%$

Step-by-step explanation:

Let

x/y ----> the fraction

we know that

100%-50^=50%=50/100=0.50

100%-25%=75%=75/100=0.75

substitute

$\frac{x}{y}*\frac{0.50}{0.75} =\frac{2}{3}(\frac{x}{y})$

therefore

The percent that the fraction will decrease is equal to

$(1-\frac{2}{3})*100=33.33\%$
