Mark and his three friends ate out at Applebee’s. Their bill totaled $52. If they left the server a 20% tip, how much would each person pay if they split the bill evenly? *

Answers

Answer:

$15.71 each

Step-by-step explanation:

I just followed the answer sheet

Answer:

$13.05

Step-by-step explanation:

Given: Mark and his 3 friends = 4 Total cost = $52, percent off: 20%

To find: How much each person would pay if they split the bill evenly.

Solution:

Firstly, since they left the server a 20% tip, multiply 20% by the total cost. Convert it to a fraction. Note: you're adding 20% to the total cost.

                                                    [tex]\frac{20}{100}[/tex] + [tex]\frac{52}{1}[/tex]

                                                      = [tex]_{52.2}[/tex]

Now, that is done, let's divide the newly found cost by the four friends.

                                                     [tex]\sqrt[4]{52.2}[/tex]

                                                   = [tex]{13.05}[/tex]

So, they would pay $13.05 evenly.

what are sides 'a' and 'b' called in a right triangle

Answers

Answer:

The relation between the sides and angles of a right triangle is the basis for trigonometry.

Step-by-step explanation:

The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b ).

Answer:

The legs

Step-by-step explanation:

In a right triangle, sides a and b are called "the legs." These are the sides that create the right angle. Side c is called the hypotenuse and it is the longest side of a right triangle. Side c is opposite of the right angle.

Given:

The equation of the line of best fit is :

[tex]y=4.722392638x+50.99539877[/tex]

To find:

The x-intercept and check whether it make sense in this context.

Solution:

We have,

[tex]y=4.722392638x+50.99539877[/tex]

Substitute [tex]y=0[/tex] to find the x-intercept of the given best fit line.

[tex]0=4.722392638x+50.99539877[/tex]

[tex]-50.99539877=4.722392638x[/tex]

If the simple interest on ​$1,000 for 8 years is ​$​ 480 then what is the interest​ rate?

Answers

Answer:

6%

Step-by-step explanation:

Given data

Principal = ​$1,000

Time= 8 years

Simple interest= ​​$480

The expression for the simple interest is

Simple interest= PRT/100

Substitute

480= 1000*R*8/100

Cross multiply

480= 8000R/100

480*100= 8000R

48000= 8000R

Divide both sides by 8000

R= 48000/8000

R=6%

Step-by-step explanation:

Answer:

64 x 40 = 2,560 <------- your area because multiply the two given lengths.

64 + 64 + 40 + 40 = 208 <---------- your perimeter since opposite sides are parallel which means 2 sides are different. So two of both of the different lengths will be your perimeter.

- Brooklynn Deka

Answer:

y = 3x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, - 1) and (x₂, y₂ ) = (5, 5)

m = [tex]\frac{5+1}{5-3}[/tex] = [tex]\frac{6}{2}[/tex] = 3 , then

y = 3x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (5, 5 ) , then

5 = 15 + c ⇒ c = 5 - 15 = - 10

y = 3x - 10 ← equation of line
