Answer:
mtx(8x+3)-3mt(8x+3)
)Step-by-step explanation:
There is 3 variable, in this case, painters, walls and time(minutes). You need to find how many painters needed and provided information on the walls and time(minutes).
Increasing walls will cause more painter needed. It was reversed in time which was increased time will cause less painter needed.
In this case, you need to divide the variable walls with time since it reversed so: 27wall/9 minutes
It equal to : 3 walls/minute
Information provided is:
3 painters= 3 walls/3 minutes
Equal to : 3 paintes= 1 wall/minute
To make it 3 walls/minute, the painter needed will be:
(3 walls/minute) / (1 wall/minute) x 3 painters= 9 painters
Answer: 9 painters
Step-by-step explanation:
let the first number be x
let the second number be y
½ of the first number= ½x
Double the second; 2*y=2y
the sum... that is ½x+2y=14
Draw up a right triangle to connect these two points with the line itself being the hypotenuse. Then use pythagorean theorem to solve for the hypotenuse
Answer:
Step-by-step explanation:
We are given that a fair 6 sided die is rolled.
Let X denotes the event that an odd number
X=1, if an odd number
X=0, if an even number
Let Y indicates the event that 2,3 or 4 is rolled .
Y=0,if 1,5 or 6 rolled
Y=1 , if 2,3 or 4 rolled
We have to find P(X=0,Y=1)
It means we have to find P(2 or 4).
When X=0 and Y=1 It means we get an even number.
P(2 or 4)=P(2)+P(4)=
Hence, P(X=0,Y=1)=
