$71.70-70%=$21.51
<span>Solution :-
Given :- Total value of restaurant bill = 90 $
Tip added in the bill = 18%
Therefore the 18 percentage on 90 is = (90*18) /100 = 16.2$
Therefore The tip value is = 16.2$
Therefore the total amount is
restaurant bill + tip value = 90$ + 16.2$ = 106.2 $
Ans : - option is c ie 106.2 $.</span>
Answer:
x=2
Step-by-step explanation:
x + 4 = 3(3x - 4)
Distribute
x+4 = 9x -12
Subtract x from each side
x+4 -x = 9x-x-12
4 = 8x-12
Add 12 to each side
4+12 = 8x-12+12
16 = 8x
Divide by 8
16/8 = 8x/8
2 =x
We can solve this problem using the Triangle Inequality property. The Triangle Inequality property states that the sum of two sides of a triangle will always be greater than the third. That being said, the only answer that works is the last one, which has the answer of 9 cm, 15 cm, and 22 cm.
Answer:
Option A - 4.91
Step-by-step explanation:
The formula for theoretical standard deviation of uniform distribution is;
σ = √{(b-a)^2}/12
Now from the question, b = 38 minutes and a= 21 minutes
Therefore, σ = √{(38-21)^2}/12
= √{17^2}/12 = √289/12 = 4.907 which is approximately 4.91
