Step-by-step equation:

15% of 60 is nine.

Percentage is equivalent to the portion of a quantity present in the whole. The portion of each person’s tip amount shared by Sara and 3 of her friends is $2.65.

A percentage is a value that indicates 100th part of any quantity.

To convert percentage into a fraction it is divided by 100.

Given that,

The amount of tip is 15% of the total amount A.

The total amount of 4 lunches = $60.

As per the question, the total amount can be written as,

15% of A = A - 60

=> 15 / 100 × A = A - 60  

=> A - (3 / 20) × A = 60

=> A - (3 / 20) × A = 60

=> (17 / 20) × A = 60

=> A = (60 × 20) / 17

=> A = 70.58

Now, the total amount of tip is,

15% of 70.58

(15 / 100) × 70.58 = 10.58

The tip shared by each friend = 10.58 ÷ 4

                                                 = 2.65

Hence, the portion of each person’s tip amount is $2.65.

Answer:

X = -2, Y = 13

X = 0, Y = 9

X = 2, Y = 5

X = 4, Y = 1

Step-by-step explanation:

Take the value given for X and plug it into the equation. For example, when X = -4, you will make your equation look as follows:

y = -2(-4) + 9

Simplify it:

y = 8 + 9

y = 17

Repeat this process with the rest of the X values to get your Y values.

Answer: Multiply 7.5% by the price after subtracting the coupon's value.

Step-by-step explanation:

Let's assume that the cost of the shirts is x. So the coupon would subtract y from x so that's x-y which gives us z. Then to find z, on a calculator just put in 7.5% x z. I used variables since I don't know the value of the coupon or the original price of the shirts.

Answer:

237

Step-by-step explanation:

The area of the regular octagon is 237 cm^2

The given parameters are:

Apothem (a) = 8.45

Side length (s) = 7

Number of sides (n) = 8

The area of the regular octagon is then calculated as:

A = 0.5 * a * n * s

This gives

A = 0.5 * 8.45 * 8 * 7

Evaluate the product

A = 236.6

Approximate

A = 237

Hence, the area of the regular octagon is 237 cm^2

Answer: [tex]f(x)=15500(1.0375)^x[/tex]

Step-by-step explanation:

The exponential model for growth is given by :-

[tex]f(x)=A(1+r)^x[/tex], where A = initial value , r = growth rate (in decimal), x = time  (in years).

Given: A= 15,500      r= 3.75% = 0.0375

The exponential model for the growth of this population will be :

[tex]f(x)=15500(1+0.0375)^x\\\\\Rightarrow\ f(x)=15500(1.0375)^x[/tex]

hence, the required model: [tex]f(x)=15500(1.0375)^x[/tex]

The average speed of the train was 80mph.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

Here, Given that, Station A and Station B are 120 miles apart.

And, a train traveling from station A to station B travels exactly 1/3 of the distance when it is held up and stops for 16 minutes.

Let, its average speed was x mph.

Then, Total time if didn't stop = 120/x h

Now, before stop it took time =( 1/3×120)/x h =40/x h

After stop it took time = 80/(x+15) h

i.e. 40/x +16/60+ 80/(x+15) = 120/x

⇒80/(x+15)+8/30= 80/x

⇒80(1/x-1/(x+15))=8/30

⇒10×(15/x^2+15x)=1/30

⇒x^2+15x=10×15×30

⇒x^2+15x-450=0

⇒x^2+75x-60x-450=0

⇒(x+75)(x-60)=0

⇒x=60 or, x= -75

Hence. the required speed was 60mph.
