A crew of highway workers paved 1/2 mile in 1/4 hour. If they work at the same rate, how much will they pave in one hour?
mote1985 [20]

Step-by-step explanation:

The easiest approach is to realise that one hour is 3 times longer than

20

minutes. The longer the time, the more they will pave.

of a mile, in 20 minutes, how much in 60 minutes?#

They will pave 3 times more.

You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by

20

) and them multiply by

60

to find how much in one hour.

Len [333]

Answer:

The relation is not a function

The domain is {1, 2, 3}

The range is {3, 4, 5}

Step-by-step explanation:

A relation of a set of ordered pairs x and y is a function if

  • Every x has only one value of y
  • x appears once in ordered pairs

<u><em>Examples:</em></u>

  • The relation {(1, 2), (-2, 3), (4, 5)} is a function because every x has only one value of y (x = 1 has y = 2, x = -2 has y = 3, x = 4 has y = 5)
  • The relation {(1, 2), (-2, 3), (1, 5)} is not a function because one x has two values of y (x = 1 has values of y = 2 and 5)
  • The domain is the set of values of x
  • The range is the set of values of y

Let us solve the question

∵ The relation = {(1, 3), (2, 3), (3, 4), (2, 5)}

∵ x = 1 has y = 3

∵ x = 2 has y = 3

∵ x = 3 has y = 4

∵ x = 2 has y = 5

→ One x appears twice in the ordered pairs

∵ x = 2 has y = 3 and 5

∴ The relation is not a function because one x has two values of y

∵ The domain is the set of values of x

∴ The domain = {1, 2, 3}

∵ The range is the set of values of y

∴ The range = {3, 4, 5}

Area of a circle is 80 cm². Work out the circumference of the circle.
GuDViN [60]

Answer:

The circumference of circle is: 31.714 cm

Step-by-step explanation:

Let C be the circumference of the circle

And A be the area of circle

It is given that:

A = 80cm^2

We have to find the radius first so that it can be used to find the circumference

The area of circle is given by the formula:

A = \pi r^2

Putting the value of area

80 = 3.14 * r^2\\\frac{80}{3.14} = r^2\\r^2 = 25.477

Taking square root on both sides

\sqrt{r^2} = \sqrt{25.477..}\\r = 5.0475\ cm

Now

C = 2\pi r

Putting the value of radius

C = 2 * 3.14 * 5.05\\C = 31.714\ cm

Hence,

The circumference of circle is: 31.714 cm
