The total cost of the meal will be $54.
45 + 20% = 54
Answer:
832
Step-by-step explanation:
If you have one group of 832, and put it into 1 group you get 832
Answer:
The value remain unchanged.
Step-by-step explanation:
By Z score, we mean:
Z = 
, if we substitute the given values of mean and standard deviation, we obtain the z score value. That is,
Z = 
= 85/12 = 7.083333.
NB: We assume that mean and standard deviation are in the same units.
Answer: closed circle pointing to the right.
Step-by-step explanation:
Given that the inequality equation is
6 ( 2 - 3y ) < = 36
Open the bracket
12 - 18y < = 36
Collect the like terms
- 18y < = 36 - 12
Make y the subject of formula
The inequality sign will change the moment you multiply or divide both sides by negative numbers
Y > = - 24/18
Y > = - 4/3
That is y is greater than or equal to negative 4/3
Graphing the above inequality,
The point will be between -2 and -1. And it will be closer to -1.
The arrow will point to the right and it will be a closed circle since it is greater than or equal to.
Answer:
x=-6
Step-by-step explanation:
Let x be the number
3x = x^2 -54
Subtract 3x
3x-3x = x^2 -3x-54
0 = x^2 -3x-54
Factor
What 2 numbers multiply to -54 and add to -3
-9*6 = -54
-9+6 = -3
0=(x-9) (x+6)
Using the zero product property
x-9=0 x+6=0
x=9 x=-6
The questions asks for the negative solution
x=-6
