Explanation:

The variable n is a placeholder for a number. Specifically some positive number. Let's say that n = 50. This means Eric biked 50 miles last year.

That would mean in total he biked 50+457 = 507 miles overall over the two years.

Since we don't know what n is, we don't replace it with 50. So we just keep n as it is. We would keep it as n+457

Once, or if, we find out the value of n, then we can replace that letter with that number.

The price of the movie itself is $19.99.

19.99 x 6% = 1.1994

19.99 + 1.1994 = 21.1894

Answer:

5/16 Got a C

Step-by-step explanation:

A = 1/4 x 32

B = (32 - A)/2

D = 2

A = 8

B = (32 - 8)/2

B = 24/2

B = 12

D = 2

8 + 12 + 2 = 22

22/32 did not get a C

32/32 - 22/32 = 10/32

The equivalent of the expression, 35 (8 – 3)  is (35 × 8 ) - (35 × 3). The answer is C.(35 × 8) – (35 × 3)

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation.

Therefore, let's simplify the expression to the its' equivalent as follows:

Hence,

35 (8 – 3) = 35(5) = 175

Therefore,  the equivalent is as follows:

35 (8 – 3)

Open the bracket by multiplying as follows;

35 (8 – 3)  = (35 × 8 ) - (35 × 3)

The correct option is C. (35 × 8) – (35 × 3)

Answer: True.

Step-by-step explanation:

Here we have the number:

26,59,360

To find the place value of the 5, we first need to count the number of decimals at the right of the 5 (until we reach the decimal point)

For this case, at the left of the 5 we have 4 decimals (9, 3, 6 and 0)

Then the place value of the 5 in that number will be 10^4

this is equal to:

10^4 = (10)*(10)*(10)*(10) = 10,000

This means that the place value of the 5 is then thousand.

Then the statement is true.

The equation of a circle with center at  [tex]C(-2, 7)[/tex]  and Point [tex]P(1, 11)[/tex] will be   [tex](x+2)^2+(y-7)^2=25[/tex] .

What is equation of a circle ?

Equation of a circle is written in the form [tex](x-h)^2+(y-k)^2=r^2[/tex] where [tex](h,k)[/tex]   is the center and  [tex]r[/tex]  is the radius.

We have,

Center at  [tex]C(-2, 7)[/tex]

i.e. [tex]h=-2[/tex], [tex]k=7[/tex],

And

Point [tex]P(1, 11)[/tex]

i.e. [tex]x=1[/tex], [tex]y=11[/tex]

Now,

To determine Radius of the circle;

[tex]r^2=(x-h)^2+(y-k)^2[/tex]

[tex]r^2=(1-(-2))^2+(11-7)^2[/tex]

[tex]r=\sqrt{3^2+4^2} =\sqrt{25}[/tex]

[tex]r=5[/tex]

So, radius of the circle is [tex]5[/tex] .

Now,

Equation of a circle ;

[tex](x-h)^2+(y-k)^2=r^2[/tex]

[tex](x-(-2))^2+(y-7)^2=5^2[/tex]

[tex](x+2)^2+(y-7)^2=25[/tex]

So, the Equation of a circle is  [tex](x+2)^2+(y-7)^2=25[/tex] .

Hence, we can say that the equation of a circle with center at  [tex]C(-2, 7)[/tex]  and Point [tex]P(1, 11)[/tex]  is   [tex](x+2)^2+(y-7)^2=25[/tex] .

Given :

A graph of Total Meals Packed vs Time( in hours ).

To Find :

How many meals would be packed in 20 hours.

Solution :

First we will find the equation of line.

Now, the line passes through ( 0, 0 ) and ( 4, 500 ).

So, equation of line passing through ( 0, 0 ) and ( 4, 500 ) is :

[tex]y - 0 = \dfrac{500-0}{4-0}( x - 0 )\\\\y = 125x[/tex]

Now, putting the value of x = 20 hours in above equation, we get :

y = 125 × 20 meals

y = 2500 meals

Therefore, number of meals packed in 20 hours is 2500 meals.

The function of the graph of a translation of the graph of f(x) = x shifted 5 units to the right is g(x) = x - 5, so option B is correct, the graph is also attached below.

When a function from one set to the other is utilized, every element of X receives precisely one element of Y. The function's domain and co-domain are collective terms used to refer to the sets X and Y, respectively.

Given:

f(x) = x, shifted 5 units to the right

A translation is a change in the graph's direction, either horizontally or vertically, parallel to the -axis.

Here, the translation is of 5 units,

Step-by-step explanation:

Given that:

Sale price of jacket = $210

New cost of jacket = $262.50

Change = New cost - Sale price

Change = 262.50 - 210 = $52.50

Percent increase = [tex]\frac{Change}{Sale\ price}*100[/tex]

Percent increase = [tex]\frac{52.50}{210}*100[/tex]
