The total cost of the dinner meals taken by Arif and Keisha = $13.75
Percentage of tax that need to be given = 5%
Then
Amount of tax that needs to be given = (5/100) * 13.75 dollars
= 13.75/20 dollars
= 0.687 dollars
= 0.69 dollars
So
The total amount that needs to be
paid for dinner including tax = (13.75 + 0.69) dollars
= 14.44 dollars
Percentage of tips that they both want to leave = 15%
Then
Amount of tips that need to be given = (15/100) * 14.44
= 216.6/100 dollars
= 2.17 dollars
So
The total amount that they should leave = (14.44 + 2.17) dollars
= 16.61 dollars
So they should leave a total of $16.61 in the restaurant.
k = 13 is the value of k in quartic equation.
What does the term "quartic equation" mean?
An equation of the fourth degree, often known as a quartic equation, is one that reduces a quartic polynomial to zero. in which a 0. A quartic function's derivative is a cubic function.
Let α = 7x
β = 6x
α + β = 7x + 6x = k/3 ............1
13x = k/3
αβ = 7x × 6x = 14/3
42x² = 14/3
x² = 14/3 × 42
x² = 1/9
x = 1/3
now putting value of x in 1
7/3 + 6/3 = k/3
1/3( 7 + 6 )= k/3
k = 13

2x +8=2(x + 4)
mutiply the bracket by 2
(2)(x)= 2x
(2)(4)= 8
2x+8= 2x+8
move 2x to the left side
sign changes from +2x to -2x
2x-2x+8= 2x-2x+8
0+8= 0+8
8= 8
Answer:
All real numbers
Volume = Length x Length x Length
Volume = Length³
Length = ∛Volume
Given that Volume = 756 in³
Length = ∛756
Answer: ∛756 (option A)
