A) Please help, In the town of blueston, there are 6 brown houses for every 8 blue houses. What is the ratio of brown houses to blue houses in blueston? b) If there are 480 blue houses in blueston, how many brown houses are there?
c) what is the value of the ratio of brown houses to blue houses?

7777

Step-by-step explanation:

do 480x 6/8

A. 6:8 or 3:4

B. 360 brown houses + 480 blues is 840 in total.

6:8

x:480

x=360 because 8 x 60 = 480 & 60x6=360.

C. 0.43

6:8 is simplified to 3:4.

Brown is 3/7 = 0.43

Blue is 4/7 = 0.57

(3+4=7)

Hope this helps!

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
