Find the total cost of a $20 lunch with an 18% tip.

Mathematics

Pachacha [2.7K]3 years ago
8 0

Answer:

$23.6

Step-by-step explanation:

The lunch normally costs $20

But you give a 18% TIP on top of that

Certainly, it will cost more. Lets find out how much exactly.

First, we need to find 18% of 20 and then ADD it to 20 to find FINAL LUNCH COST.

To convert percentage to decimal, we divide by hundred. After that we multiply with 20 to get 18% of 20. Process shown belowL

18% = 18/100 = 0.18

Then,

0.18 * 20 = $3.6

Adding to $20, we get total cost:

20 + 3.6 = 23.6 dollars

Total Cost = $23.6

kogti [31]

First definition matches with expression, second matches with equation ,third matches with algorithm and fourth matches with equation.

Given  four definitions of equation, expression, algorithm but mixed.

We have to match the definitions with appropriate term.

We know that expression is a combination of numbers, symbols, fraction, coefficients, indeterminants mostly not found in equal to form. It exhibits a behaviour only.

Algorithm is a computer programming to do a specific task in a predetermined way.

Equation is a relationship between two variables expressed in equal to form. In this we have to put the value of variables and the equation gives us a value.

Hence  First definition matches with expression, second matches with equation ,third matches with algorithm and fourth matches with equation.

Answer:

Area of parallelogram is 150 square ft

Step-by-step explanation:

Given the parallelogram in the figure whose height is 10 ft and base length is 15 ft.

Area of parallelogram is base \times height

                                       = 15\times 10ft^2

                                       = 150 square ft

now we have to decompose this parallelogram into rectangles and triangles and then to determine the shape.

The given parallelogram KLMN can be decomposed into 2 triangles and one rectangle.

2 right angled triangles KPL and NOM by construction

KL^{2}=KP^{2}+PL^{2}=10^{2}+2^{2}                                          =100+4=104

⇒ KL=\sqrt104=10.2 ft=MN         (∵ KLMN is a parallelogram)

Hence, dimension of triangles are 10 ft, 2 ft and 10.2 ft

Now rectangle KPON with dimension 15 ft and 10 ft because KP and NO are perpendiculars on LM.
