You would have one tenths (1/10) of a chance to get a 4 on the first go. you would have four ninths (4/9) of a chance to get a number less than 5 out of the bag on the second go.

the overall probability would be two forty-fifths (2/45)

K=1/2 mv squared, determined m when v=30 and k=4500.
WITCHER [35]

Given the expression:

\text{ k = }\frac{1}{2}mv^2

At v = 30 and k = 4,500 , let's determine m.

\text{ k = }\frac{1}{2}mv^2\frac{2k}{v^2}\text{ = m }\rightarrow\text{ m = }\frac{2k}{v^2}

We get,

\text{ m = }\frac{2k}{v^2}\text{ = }\frac{2(4,500)}{(30)^2}\text{ = }\frac{9,000}{900}\text{ m = 10}

Therefore, m = 10.

At a wedding reception, the caterer served fishing chicken. The fish dinner cost $12 per person in the chicken cost $9 per perso
maw [93]

Answer:

80 persons haf fish and 152 persons had chicken

Step-by-step explanation:

Given data

let the number of persons that had fish be x and chicken be y

so

12x+9y=2544------------------1

x+y= 232------------------------2

from 2

x= 232-y

substitute the value of x in 1

12(232-y)+9y=2544

2784-12y+9y=2544

2784-3y=2544

3y= 2784-2544

3y=240

y= 240/3

y=80

put y= 80 in 2

x+80= 232

x= 232-80

x=152

Hence 80 persons haf fish and 152 persons had chicken

Factor the expression using distributive property: 72b + 45
ANTONII [103]
The answer would be 9(8b+5)
this is how you do it...
1. find the GCF of both numbers in this one the GCF would be 9 
now, what do you multiply 9 by to get 72... 8, so 8 would go into the parenthesis and because there is a variable there which is 'b' the 8 would become '8b' now what do you multiply 9 with to get 45? '5' so you would add 5 into the parenthesis and that would be your answer!

Hope this helped! :D

Consider a bag containing four red marbles, three green ones, one transparent one, three yellow ones, and three orange ones.
Allisa [31]

Answer:

21

Step-by-step explanation:

Given,

  • Number of red marble = 4
  • number of green marble = 3
  • number of transparent marble = 1
  • number of yellow marble = 3
  • number of orange marble = 3

Total number of marble except red and green  = 3 +3+1

                                                                               = 7

So, the total number of possible sets of five marbles such that none of them are green or red can be given by

n\ =\ ^7C_5

   =\ \dfrac{7!}{(7-5)!.5!}

   =\ \dfrac{7!}{5!.2!}

  =\ \dfrac{42}{2}

   = 21

So, the required number of possible sets are 21.
