X should be 12 because the area of the triangle is base (x) times height (4) divided by 2. So if x is 12, 12 times 4 is 48 divided by 2 is 24 units squared

A plank of wood is 220 cm long.I cut it in 14cm pieces. what lenght of wood i will have left over?
Nana76 [90]

The required Length is 10cm.

What is length?

  • Length is a measure of distance. In the International System of Amounts, length is a volume with dimension distance. In utmost systems of dimension a base unit for length is chosen, from which all other units are deduced.
  • Length is generally understood to mean the most extended dimension of a fixed object. still, this isn't always the case and may depend on the position the object is in.
  • Varied terms for the length of a fixed object are used, and these include height, which is the perpendicular length or perpendicular extent, and range, breadth, or depth. Height is used when there's a base from which perpendicular measures can be taken. range or breadth generally relates to a shorter dimension when the length is the longest one.

220 / 14 gives us 15.

You have to understand that this means 15 whole 14 cm pieces and a Length of 1 piece.

thus 14 * 15 = 210

So 220- 210 = 10

where you know 220- 210 is< 15

Hence, The correct Length is 10cm.

I need help with the first two
mel-nik [20]
The work and answer provided are correct, the simpler way of doing it is

1)
1/6 page written in 1/12 of a minute
to write a full page, you would need to write 1/6, 6 times
so,
\frac{1}{6} \time 6 = 1
and
\frac{1}{12} \times 6 = \frac{6}{12} = \frac{1}{2}

so it takes 1/2 of a minute to write a full page, there are 60 seconds in a minute, 1/2 of 60 seconds is 30 seconds

same process works for question 2(use 3 instead of 6 though)

Musya8 [376]

Answer:

10

Step-by-step explanation:

one interior angle in a pentagon is 108^o.

5 interior angles are 540^o.

If we add 12+7+16+9+10, we get 54x=540^o

That means x=10
