To make 3 cups of rice, Nina needs 5 cups of water. To make 9 cups of rice, she needs 15 cups of water. Write this as a proportion.

Step-by-step explanation:

Here is the answer for the unkown n(k+m)

Answer:

n*(k+m)

Step-by-step explanation:

1.

total surface area Stot = 20.4924225 cm2

lateral surface area Slat = 16.4924225 cm2

bottom surface area Sbot = 4 cm2

2.

total surface area Stot = 46.1079506 ft2

lateral surface area Slat = 37.1079506 ft2

bottom surface area Sbot = 9 ft2

3.

total surface area Stot = 95.0467761 ft2

lateral surface area Slat = 68.0067761 ft2

bottom surface area Sbot = 27.04 ft2

Answer:

[tex]a_{n}=45-3n[/tex]

Step-by-step explanation:

Method 1:

Arithmetic sequence is in the form

[tex]a_{n} =a_{1} +(n-1)d\\[/tex]

d is the common difference, can be found by:

[tex]d=a_{n}-a_{n-1}=-3[/tex]

Subtituting the [tex]a_{1}[/tex] and [tex]d[/tex]

You get:

[tex]a_{n}=42+(-3)(n-1)=45-3n[/tex]

Method 2 (Mathematical induction):

Assume it is in form [tex]a_{n}=45-3n[/tex]

Base step: [tex]a_{1} =45-3(1)=42[/tex]

Inducive hypophesis: [tex]a_{n}=45-3n[/tex]

GIven: [tex]a_{n+1} =a_{n}-3[/tex]

[tex]a_{n+1}=45-3n-3=45-3(n+1)[/tex]

Proved by mathematical induction

[tex]a_{n}=45-3n[/tex]

Answer:

105

Step-by-step explanation:

Answer:

$77

Step-by-step explanation:

80% of 350 is 280

it is $280 off so 350-280=70

then the tax, 10% of 70 which is 7

the answer is $77 because 70+7=77

Answer:

its C

Step-by-step explanation:

Answer:

10 ft.

Step-by-step explanation:

By using the pytahgorean theorem a² + b² = c² we can determine the answer of 10 ft. If you do not know already the length and width are the a and the b so a=6 and b=8. by squaring both of these we get a=36 and b=64 (squaring is just the number times itself so 3² would be 3x3) by adding both of these squared values we get 64+36=100 which means that c²=100 so to get our final answer we just take the square root of c² which is the opposite of squaring it. So √100=10 and that is our final answer

Answer:

62.5%

Step-by-step explanation:

Answer:

62.5%

Step-by-step explanation:

Answer:

Step-by-step explanation:

7x + 9 = 58

     -9    -9      Subtract 9 from both sides

7x = 49

/7     /7           Divide both sides by 7

x = 7 (this is an apporximation)

Answer:

7

Step-by-step explanation:

1st you need to subtract 9 from both sides like this: 7x+9-9=58-9. and you'll get 7x=49. Then, divide by 7 on both sides like this: 7x/7=49/7. and you'll get x=7.

Radius = 5 cm

Height = 8 cm

Volume = πr²h

Volume = π(5 cm)² × 8 cm

Volume = π × 25 cm² × 8 cm

Volume = 200π cm³

Answer:

-5f    +6

Step-by-step explanation:

-4f - 9 - f + 15

Combine like terms

-4f -f    -9 +15

-5f    +6

Answer:

-5f+6

Step-by-step explanation:

as we add like terms -4f+(-f)=-5f

-9+15=6

Answer:

D 13

Step-by-step explanation:  L+L+W+W=Perimeter

2(1/4x)+2(2x+1)=4.5x+2            

4.5x+2=29        Subtract 2

4.5x=27             Divide by 4.5

x=6                                                            1/4(6)= 1.5 W=1.5      1.5(2)=3

                                                                 2(6)+1=13                  13(2)=26

                                                                                   26+3=29inches perimeter

Answer:

A: 12 4/9

Step-by-step explanation:

1/4x (2x + 1) = 29 (Combine like terms, NOT distributive property!!!)

   2 1/4x + 1 = 29

               - 1    - 1

2 1/4 / 2 1/4x = 28 / 2 1/4

                  x = 12 4/9
