padilas [110]3 years ago
5 0

Answer:

Area of the trapezium = 30 cm^{2}

Step-by-step explanation:

a = 14

b = 4

h= 5

Area of trapezium =  \frac{1}{2} }  ( a + b) h = \frac{1}{2} (14+4) 5

= \frac{1}{2} x 18 x 5 = 6 x 5 <em> [I solved  </em>\frac{1}{2}<em> and 18]</em>

= 30!

What is the length of the arc shown in​ red?
professor190 [17]

Answer:

≈ 18.8 cm

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

The central angle is equal to the arc subtending it, that is 60°

  arc = 2πr × \frac{60}{360}

        = 2π × 18 × \frac{1}{6}

        = 36π × \frac{1}{6}

        = 6π ≈ 18.8 cm ( to 1 dec. place )

A hairdresser is deciding where to open her own studio. If the hairdresser chooses Location A, she will pay $1200 per month in r
Ymorist [56]
She will need to cut 26.6 haircuts a month a location A to break even (1200/45 = 26.6) so roughly 27 haircuts to make a profit


She will need to cut 30 haircuts at location B to break even (1800/60 = 30) and 31 hair cuts to see a profit.


She will need to cut 30.67 haircuts at location A and 33 haircuts at location B to make the same profit at either location (Roughly $180).


30.67 x 45 = 1380.15 - 1200 = 180

33 x 60 = 1980 - 1800 = 180

........I need help! Thanks in advance

You can find the slope using the points.
9-18          -9         9
--------- = ------- = -------
-14+10     -4          4
Next, you can find the equation of the line.
y-9=9/4(x+14)
y=9/4x+40.5
Plug in 0 for x.
y=9/4(0)+40.5
y=40.5
So, the y-intercept is (0,40.5)
Plug in 0 for y.
0=9/4x+40.5
-40.5=9/4
x=-18
So, the x intercept is (-18,0)
I hope this helps!
