Stephanie's age is 3 years greater than half of her sister's current age. If her sister is 24 years old, what is Stephanie's age?​

Answers

Answer 1

Answer: Stephanie is 15

Step-by-step explanation:

because you can do 24 divided by 2 which equals 12 then add three to 12 and you get 15.

you're welcome! plz lmk if i'm wrong XD

Answer 2

Stephanie's age is 3 years greater than half of her sister's current age. If her sister is 24 years old, then Stephanie's age is 15 years.

To find Stephanie's age, we need to follow the given information that her age is 3 years greater than half of her sister's current age.

First, we find half of her sister's age: Half of 24 = 24 / 2 = 12

Next, we add 3 years to half of her sister's age: 12 + 3 = 15

Therefore, Stephanie's age is 15 years.

Age can be used in mathematical equations and word problems to solve for unknowns or to establish relationships between different quantities. For example, age-related math problems might involve scenarios such as Finding someone's age given their birth year and the current year,  Calculating the average age of a group of people and Determining the age difference between two individuals based on their birth years.

2) The wire length 176 cm is first bent into a square
and then into a circle
which one will have more area? (II= 22/7)

Answers

Length of Wire = 176 cm

It's bent into a square.

Side of square = 176/4 = 44 cm

Area of square = Side × Side = 44 × 44 = 1,936 sq.cm

Then it's bent into a circle.

Circumference of the circle = 2πr = 176 cm

Circumference = r = 176/2 × 7/22 = 28 cm

Area of circle = πr^2

Area = 22/7 × 28 × 28

Area = 2,464 sq.cm

The Circle will have more area than the square.

The midpoint of AB is M (5,1). If the coordinates of A are (3,6), what are the
coordinates of B answers

Answers

The midpoint of a line segment means a point that lies in the mid of the given line segment. The coordinates of point B are (7, -4).

What are the coordinates of the midpoint of the line segment AB?

Midpoint, as the word suggests, means the point which lies in the middle of something. The midpoint of a line segment means a point that lies in the mid of the given line segment. Suppose we've two endpoints of a line segment:

A(p,q), and B(m,n)

Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:

[tex]x = \dfrac{p+m}{2}[/tex]

and

[tex]y = \dfrac{q+n}{2}[/tex]

Given that the midpoint of AB is M whose coordinates can be written as,

The x-coordinate of point B,

[tex]x_m = \dfrac{(x_A + x_B)}{2}[/tex]

[tex]5 = \dfrac{(3 + x_B)}{2}[/tex]

10 = 3 + x

x = 10 - 3

x = 7

The y-coordinate of point B,

[tex]y_m = \dfrac{(y_A + y_B)}{2}[/tex]

[tex]1 = \dfrac{(6 + y_B)}{2}[/tex]

2 = 6 + y

y = 2 - 6

y = -4

Hence, the coordinates of point B are (7, -4).

three friends all live on the same street that runs west to east. Beth lives 6 blocks from Al. Carol lives 2 blocks from Beth. If the street is represented by a number line and Al’s house is located at 0, what are the possible locations for Carol’s house?

Answers

Answer:2, -2, 6 or -6

Step-by-step explanation:

Given,

The location of Ann's house in the number line = 0,

∵ Ben lives 4 blocks from Ann.

So, the possible location of Ben's house =  4 ( right of ann's house ) or - 4 ( left of ann's house )

Now, Carl lives 2 blocks from Ben,

So, the possible location of Carl's house

Case 1 : If Ben's house location is 4 = 2 ( left of ben's house ) or 6 ( right of ben's house )

Case 2 : If Ben's house location is -4 = -2 ( right of ben's house ) or -6 ( left of ben's house )

Please help ik its kinda esay but is dificlut for me

Answers

Answer:

see explanation

Step-by-step explanation:

For a relation to be a function each value of x on the domain can only map to one unique value of y in the range.

For the given point, we can see that

x = 1 → y = 4 and x = 1 → y = 1

This breaks the function rule, thus the set is not a function

Explanation:

The list of first numbers of the ordered pairs is ...

  1, 3, 1, 9, 0.

There is a repeated value, 1, so the relation cannot be a function. Each domain value can only appear once in a relation that is a function.

what is 3=x+3-5x i dont know what to do

Answers

Answer: 0

Step-by-step explanation:

No matter how you go at it, x is inevtably going to equal 0. To get x by itself, you have to subtract 3 from the right and left side, which leaves 0=x-5x. That leaves you with -4x=0, and when divided, that equals zero.

Answer:

x = 0

Step-by-step explanation:

Given

3 = x + 3 - 5x , that is

3 = - 4x + 3 ( subtract 3 from both sides )

0 = - 4x , thus

x = 0
