18 is 36% of 50.

<u>Solution: </u>

Need to determine what percent of 50 is 18.

Let's assume x % of 50 is 18.

x % can be written in fraction as \frac{x}{100}

Hence  x % of 50 is written as,

\frac{x}{100} \times 50=18

\begin{array}{l}{\Rightarrow \frac{x}{2}=18} \\ {\Rightarrow x=18 \times 2=36 \%}\end{array}

So 18 is 36% of 50.

This can also be determined by another method.

18 out of 50 can also be written as 18/50

Percentage is equal to numerator when denominator is 100.

So we need to find equivalent rational number of \frac{18}{50} where denominator = 100

On multiplying numerator and denominator by 2 we get

\frac{18 \times 2}{50 \times 2}=\frac{36}{100}=36 \%

Hence 18 is 36% of 50.

Your friend claims that if a line has a slope less than 1, then any line perpendicular to it must have a positive slope. Is your
mezya [45]

Answer:

The friend's claim is not correct

Step-by-step explanation:

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal yo -1)

Example

A given line has a slope of m_1=1/2  ---> (is less than 1)

the slope of the line perpendicular to the given line is equal to

m_1*m_2=-1

substitute

(1/2)*m_2=-1

m_2=-2

so

the perpendicular line don't have a positive slope

therefore

The friend's claim is not correct

Solve for the values of x and y in each item to make the given quadrillater a parallelogram​
maria [59]

Answer:

For given parallelogram, the value of x = 114° and y = 66°

Step-by-step explanation:

(Refer figure)

Given quadrilateral ABCD is a parallelogram.

m∠A = 66°

m∠B = x°

m∠C = y°

m∠D = 114°

Since by properties of parallelogram, the both pairs of opposite sides of a parallelogram are parallel.

Opposite angles of a parallelogram are congruent ...........................(1)

Consecutive angles of a parallelogram are supplementary ................(2)

Using (1) for given parallelogram ABCD; we get,

m∠B = m∠D

m∠A = m∠C

Therefore x = 114° and y = 66°.

Using (2) to check whether the two consecutive angles are supplementary.

( m∠A + m∠D ) =  ( m∠B + m∠C ) = ( m∠C + m∠D ) = 66° + 114° = 180°

Hope it helps!!

A cube has its length doubled and its width and height remain the same. How does the new volume compare to the old volume?
Evgen [1.6K]

The new value will be double of the old volume.

Step-by-step explanation:

Let l be the length of cube

w be the width of the cube

and

h be the height of the cube

then the volume of cube is given by:

V = lwh

Now,

Doubling the the length, 2l

The new volume will be:

V_n = 2lwh\\V_n = 2(lwh)\\V_n = 2V

Hence,

The new value will be double of the old volume.
