Answer:

31.5 squared cm

Step-by-step explanation:

Let's start with the triangle part :)

We have a base half a base of 3, so let's add 3 more to make it complete, which gives us 6.

6cm (base) x 6 cm (height) = 36 cm.

Since it's a triangle, we must divide by 2 which gives us 18 cm.

Now let's move on to the circle.

we have a radius of 3.

in order to find area of a circle, we have to do pi x r squared.

We have a radius of 3 so let's square it, which give us 9. after that we multiply 9 by pi.

In the directions, it says use 3 for pi. So we do

3 x 9 which equals 27.

But WAIT- it's a half circle so we divide 27 by 2 which gives us 13.5 cm.

Let's add the two

18 cm + 13.5 cm = 31.5 cm squared (remember to square it since it's area!!)

I hope this helped!!! <3

Sherry bought a sport utility vehicle. She received a discount of 18% off the manufacturer's list price but then had to pay 8% s

Kazeer [188]

Answer:

x = $20,000

the manufacturer's list price is $20,000

Step-by-step explanation:

Let x represent the manufacturer's list price.

And c the amount she finally paid

Given that;

She received a discount of 18% off the manufacturer's list price

= x - 18%x

= x - 0.18x

= 0.82x

then had to pay 8% state sales tax.

C = (0.82x) + 8% of (0.82x)

C = 0.82x + 0.08(0.82x)

C = 0.82x + 0.0656x

C = 0.8856x

Since she paid $17,712

C = $17,712

C = $17,712 = 0.8856x

0.8856x = $17,712

x = $17,712/0.8856

x = $20,000

the manufacturer's list price is $20,000
