Multiple choice maths measurement (length) conversion of length using decimals in units of length define weight and units of weight how much does it weigh?

The graphs of $2x+3y-6=0$, $4x-3y-6=0$, $x=2$ and $\displaystyle y=\frac{2}{3}$ intersect in __________.

  1. Four points

  2. One point

  3. In no points

  4. In infinite number of points
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

On solving  2x+3y−6=02x+3y−6=0 and 4x−3y−6=04x−3y−6=0, we get

x=2x=2 and y=23y=23

Hence, from all the four given equations, the!li value of x is 2 and y is 2323

Therefore, the graphs of all the four lines intersect in one point.

A carpenter cuts off $1.3$ inches from a $4$-foot board. What is the new length of the board in inches?

  1. $2.7$ inches
  2. $46.7$ inches
  3. $49.3$ inches
  4. $58.7$ inches

B Correct answer
Explanation

Of the two lengths given in the problem, one is inches and the other is in feet. The answer needs to be inches, so convert the length of the board to inches. Since there are $12$ inches in one foot, the 4-foot board is $48$ inches long. Now subtract the length of the piece the carpenter cut off.
$48-  1.3 = 46.7$
Therefore, the new length of the board is $46.7$ inches.

Convert the following measurement into $cm$
$3.44\ m$

  1. $3.44\ cm$
  2. $34.4\ cm$
  3. $344\ cm$
  4. $3440\ cm$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

We know that


$1$  $meter =100$  $cm$

$1$  $cm =\dfrac1{100}$  $m$

Given That , we have to convert $3.44$  $m$ into $cm$

$3.44$  $m =3.44 \times 100$  $cm$

                $=344$  $cm$

So, Option $C $ is correct

Convert the following into metres and centimetres.
$673\ cm$

  1. $6\ m$ $73\ cm$
  2. $67\ m$ $3\ cm$
  3. $673\ m$ $0\ cm$
  4. $73\ m$ $6\ cm$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

We know that


$1$  $meter =100$  $cm$

$1$  $cm =\dfrac1{100}$  $m$


$673$  $cm =\dfrac1{100} \times 673$  $m$

                $=\dfrac{673}{100}   $  $m$

                 $= 6.73  meter$

It is equivalent to $6$ $meters$ and $73$ $cms$
So, Option $A$ is correct
