Answer:
A
Step-by-step explanation:
The rhombus cuts the shorter side of the rectangle in half so it's equal to 5
we use pythagoras
so the larger side is 2x=24
so the area is 24*10=140cm^2
Answer:
Step-by-step explanation:
Probability that a particular song p = 0.41
q = 1 - p = 1 - .41 = .59
n = 4 , r = 0
Probability that this song will be played on exactly 0 days = 
= 
= 4 x 1 x .1211 = .484
Answer:
Elsa - 17 orders
Deon - 22 orders
Carlos - 68 orders
Step-by-step explanation:
You need to set variables and create system of equations first.
Elsa= e
Deon= d
Carlos = c
e+d+c=107
d=e+5
c=4e
Now you plug in the values into the equation x+y+z=116
e+(e+5)+(4e)=107
6e+5=107
6e=102
e=17
You plug in the value of x into the other equations.
e = 17
d= 17+5=22
c=4*(17)=68
Rearrange so it corresponds with days...
Elsa - 17 orders
Deon - 22 orders
Carlos - 68 orders
Hello!
First you have to find either x or y
We can use the second equation to find y
-8 + 2y = -20
Add 8 to both sides
2y = -12
Divide both sides by 2
y = -6
We can plug -6 in for y in the other equation
-8x - 8(-6) = 0
-8 * -6 = 48
-8x + 48 = 0
subtract 48 from both sides
-8x = -48
divide both sides by -8
x = 8
So the answers are x = 8 and y = -6
Hope this helps!
all real numbers except -3 because that will result in a denominator of 0 which will make it undefined :)
