Answer:

You forgot the question~

Step-by-step explanation:

Yes, that's the true statement, but you forgot what we should answer. I can give you a list that what your question is asking.

Probably it's r(1) or others.

I'm not sure this is helpful though...

r(0) = 0

r(1) = 40

r(2) = 80

And so on until 10, because he only got 10 trees to sell.

Answer:

4) 120π cm^2

5) 56π cm^2

6) 32π cm^2

Step-by-step explanation:

Surface Area of Cylinder = 2πr^{2} + (2πr)(height)

(will use variable h for height)

4)

diameter = 8 cm

r = 0.5(diameter) = 0.5(8) = 4 cm

height = 11 cm

2π4^{2} + (2π)(4)(11)

= 2π(16) + 2π(44)

= 32π + 88π

= 120π cm^2

5)

diameter = 8 cm

r = 0.5(diameter) = 0.5(8) = 4 cm

height = 6 cm

2π4^{2} + (2π)(4)(6)

= 2π(16) + 2π(12)

= 32π + 24π

= 56π cm^2

6)

diameter = 6 cm

r = 0.5(diameter) = 0.5(6) = 3 cm

height = 7 cm

2π3^{2} + (2π)(3)(7)

= 2π(9) + 2π(7)

= 18π + 14π

= 32π cm^2

Answer:

steps below

Step-by-step explanation:

3.2.1   AD = DB* sin 2 = DB * sin θ   .. DE // AB   ∠2= θ  ... (1)

By laws of sines:  DB / sin ∠5 = x / sin ∠4    

∠4 = θ-α     ∠5 = 180°-<u>∠1</u>-∠4 = 180°-<u>∠3</u>-∠4 = 180°-(90°-θ)-(θ-α)) = 90°+α

DB = (x*sin ∠5)/sin (θ-α)

     = (x* sin (90°+α)) / sin (θ-α)

AD = DB*sinθ

     = (x* sin (90°+α))*sinθ / sin (θ-α)

     = x* (sin90°cosα+cos90°sinα)*sinθ / sin (θ-α)    .... sin90°=1, cos90°=0

     = x* cosα* sinθ / sin (θ-α)

3.2.2 Please apply Laws of sines to calculate the length

Jorge is mixing a special shade of orange paint. He mixed 1 gallon of red paint with 3 gallons of yellow paint. Based on this ra
astra-53 [7]

Answer:

a. b. c. and d.  are true; e. is false

Step-by-step explanation:

1 gallon of red paint : 3 gallons of yellow paint

                                  &

1 gallon of red paint + 3 gallons of yellow paint = 4 gallons of orange paint

<em>a. 3/4 of a 4-gallon mix would be yellow paint.</em>

<em>True. 3 out of 4 gallon mix is yellow and 1 out 4 is red</em>

<em />

<em>b. Every 1 gallon of yellow paint requires 1/3 gallon of red paint.</em>

1 gallon of red paint : 3 gallons of yellow paint

divide by 3 in both sides of :

1/3 gallon of red paint : 3/3 gallons of yellow paint

<em>1/3 gallon of red paint: 1 gallon of yellow paint. True</em>

<em />

<em>c. Every 1 gallon of red paint requires 3 gallons of yellow paint.</em>

<em>True. </em>1 gallon of red paint : 3 gallons of yellow paint

<em />

<em>d. There is 1 gallon of red paint in a 4-gallon mix of orange paint.</em>

<em>True. 1 out of 4 is red and 3 out of 4 is yellow.</em>

<em />

<em>e. There are 2 gallons of yellow paint in an 8-gallon mix of orange paint.</em>

<em />

1 gallon of red paint + 3 gallons of yellow paint = 4 gallons of orange paint

Multiply by 2 each side of the equation

2(1 of red paint + 3 of yellow paint) = 2(4 of orange paint)

apply to each member of the parenthesis ()

2 of red paint + 6 of yellow paint = 8 of orange paint

Actually there are 6 gallons of yellow paint in a 8 gallon mix. So e. is false.
