A line has a slope of 2/3 and a y-intercept of −5.Which equations represent the line?

Choose all answers that are correct.

A.-2x + 3y = -15

B.y= 2/3x - 5

C.6y = 4x - 30

D.(y + 3) = 2/3 (x - 3)

Answers

Answer 1
Answer: B because there is no number for y and it's already in slope intercept form so the 2/3 is the slope and -5 is the y intercept y=2/3-5 which is B

1 batch . . . . 2-1/4 cups
2 batches . . 4-1/2 cups
3 batches . . 6-3/4 cups
4 batches . . 9 cups

7 batches . . 7(2 + 1/4) =

                   (7 x 2) + (7 x 1/4) =

                     14     + ( 7/4) =

                     14  +    1-3/4  =  15-3/4


c). Write a proportion:       (1 batch) /(3 dozen)  = (x) / (200 cookies) 

1 dozen = 12 cookies
3 dozen = 36 cookies

So the proportion is     (1 batch)/(36 cookies) = (x) / (200 cookies)

Cross-multiply:         (1 batch) x (200 cookies) = ('x' batch) x (36 cookies)

Divide each side by  (36 cookies):

                           (1 batch x 200 cookies / 36 cookies) = 'x' batch

                           (200 batch / 36)   =   'x' batch

                                     x = 200/36 = 5.55 batches   

If you can only make whole batches, then you need to make 6 of them
in order to have at least 200 cookies.


d). There's more than one possible unit rate here:

--   2.25 cup flour per batch

--  0.75 cup flour per dozen cookies

--  0.0625 cup flour per cookie

--  16 cookies per cup flour

--  0.444 batch per cup flour

etc.

Which container has the greatest surface area? (Use 3.14 for π .)cone
cylinder
square pyramid
rectangular prism

Answers

Answer:

the cylinder container has the greatest surface area.

Step-by-step explanation:

The volume of cone is calculated byv=(1)/(3)*\pi* r^(2)* h

The volume of cylinder is calculated byv=\pi* r^(2)* h

The volume of square pyramid is calculated byv=\pi* r^(2)* h

The volume of rectangular prism is calculated byv=(1)/(3)* B* h

The radius of cone is (6)/(3)=2in, and slant height is 10 in.

height is calculated as h² = l²- r²

h² = l²- r²

h² = 10²- 3²

h² = 100- 9

h² =91

h= 9.54

The volume of cone is  =(1)/(3)* 3.14* 3^(2)* 9.54

=(1)/(3)* 3.14* 9* 9.54

v=89.8668

The volume of cylinder is =3.14* 3^(2)* 10

=3.14*9* 10

v=282.6

The volume of square pyramid

The height of pyramid is calculated as h² = l²- r²

h² = 10²- 3²

h² = 100- 9

h² =91

h= 9.54

v=3.14* 3^(2)* 9.54

v=3.14* 9* 9.54

v=269.60

The volume of rectangular prismv=(1)/(3)* 6* 10

v=20

Hence, the cylinder container has the greatest surface area.

Answer:

It is the Rectangular Prism.

Christian has a large rectangular container that is 30 inches by 20 inches by 20 inches. He also has a small cubical container with each side 10 inches. If he fills up the small container with water and pours into the large container, the water reaches to how many inches?

Answers

find volumes
V=LWH
large is
30*20*20=V=12000 in^3

small is 10 by 10 by 10
V=10*10*10
V=1000

how many times of smaller=larger
hw many times 1000=12000
divide both sides by 1000
how many times =12


answer is 12 times
