Answer:

27 minutes to complete the painting of 4 walls

Step-by-step explanation:

since 16m with 9p --> 8 walls

x minutes with 4p --> 6 walls?

let x= minutes

6 walls painted=(8/144 walls painted per minute)x

simplify

x= 6 divided by (8/144)

x=108 minutes (to complete 6 walls)

108/4=

27 minutes to complete the painting of 4 walls

If a punch bottle says 20% fruit juice,and it is a 200 milliliter bottle, how many milliliters of fruit juice is in the bottle?
padilas [110]

Answer:

There are 40 milliliters of fruit juice in the bottle

Step-by-step explanation:

we know taht

20%=20/100=0.20

To find out the milliliters of fruit juice, multiply the volume of the bottle by the percentage of fruit juice in decimal form

so

200(0.20)=40\ ml

therefore

There are 40 milliliters of fruit juice in the bottle

Find the equation of the line that is parallel to the line x + 5y = 10 and passes through the point (1,3).
Nataliya [291]

Answer:

Step-by-step explanation:

for two lines to be parallel they MUST have the same slope but have different Y intercepts ( Y axis crossing values)

parallel lines will never intersect each other

first I use a graphing calcuator to solve the problem

I like to use y intercept form better, but you don't have use it

I will try to solve it directly without going through the y intercept equation

x + 5y = 10    in y intercept form y = mx + b is

5y = -x + 10     divide both sides by 5

y = -x/5 + 10/5    

y = -x/5 + 2

Now I need to find a parallel line that passes through the x =1 and y = 3 point recall this line will have the same slope =     m = -1/5

and a different Y axis crossing point 'b' that we don't know

y = -x/5 + b      y = 3 when x = 1 so slove for 'b'

3 = -1/5 + b

3 = -0.2 + b    add -0.2 to both sides

3.2 = b

y = -x/5 + 3.2     this is answer in y intercept form

                          if you multiply both sides by 5

5y = -x + 16        add x to both sides

x + 5y = 16         answer in standard form

THE EASIER WAY TO SOLVE THE PROBLEM IS ......

x + 5y = 10      find a line parallel that passes through x  = 1,  y = 3  

x + 5y = Z       Z is an unknown value  plug in x and y and solve for Z

1 + 5(3) = Z

Z = 16              so the parallel line in standard form is

x + 5y = 16    

same as before,  my y intercept method was correct, but not  worth the effort

Find the distance BF for the points B(1,-1) and F(-3,5)
Nadusha1986 [10]
Use the distance formula: 
<span>\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}
<span>
Plug in the given coordinates: 
</span><span>\sqrt{(-3-1)^2 + (5-(-1))^2}
<span>
Simplify: 
</span>\sqrt{(-3-1)^2 + (5+1))^2}

\sqrt{-4^2+ 6^2}

\sqrt{16+36}

\sqrt{52}
You can leave it as: \sqrt{52}or in decimal form as: 7.2

Very confusing problem
Ronch [10]

Answer:

b = 5

Step-by-step explanation:

if parallelogram is a rectangle, then the two diagonals has the same length

10/12 x(24/5 x b - 36/5) = 2/3 x (3b + 6)

4b - 6 = 2b + 4

2b = 10

b = 5
