Which operation has to be calculated first in this expression?
7 – (4 + 5)

Answers

Answer 1

Answer:

Addition

Step-by-step explanation:

You should add 4 and 5 first because of PEMDAS.

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

Since 4+5 is in parentheses it should be done first.

Answer 2

Answer:

Addition

Step-by-step explanation:

This the answer because:

1) First, we have to know the Order of Operations

2) An easy way of remembering this is PEMDAS or GEMS

PEMDAS : Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction

GEMS : Grouping (Parenthesis), Exponents, Multiplication and Division (whichever one comes first from left to right), Addition and Subtraction (whichever one comes first from left to right)

3) In this expression, parenthesis would be first because that's what comes first in the order of operations

4) Inside the parenthesis is another expression where you need to add. Therefore, the answer is addition

Hope this helps!

Adam wraps the top edge of the gift box shown with gold ribbon. The top and bottom edges of the box are square. If Adam has cm of gold​ ribbon, does he have enough to decorate the top of the​ box?

Answers

This question is incomplete and lacks the required diagram

Complete Question

Adam wraps the top edge of the gift box shown with gold ribbon. The top and bottom edges of the box are square. If Adam has 24 1/4 inches of gold​ ribbon, does he have enough to decorate the top of the​ box?

Answer:

Yes, he has enough ribbon to decorate the top of the box.

Step-by-step explanation:

From the above question, we are told that the volume of the box = 296cm³

Volume of the box = a³

296cm³ = a³

a = √296cm³

a = 6.6644437033cm

The side length of the box = 6.6644437033cm

The length of the ribbon = 24 1/4 inches

= 24.25 inches long.

Converting this to centimeters =

1 inch = 2.54cm

24.25 inches =

24.25 × 2.54 cm

= 61.595cm.

Length of the ribbon = 61.595cm.

Since from the above, we know the edges of the cube = square

Edge length of the box = 6.6644437033cm

The perimeter of a top of the box

= 4a

= 6.6644437033cm × 4

= 26.657774813 cm

Subtracting the perimeter of the top of the box from the length of the ribbon

61.595cm - 26.657774813 cm

= 34.937225187 cm ( ribbon left)

Therefore, he has enough ribbons left

Kim poured a 24-ounce container of orange juice into 5 cups. She poured the same amount of juice into each cup. Write a rational number that represents the amount of juice in each cup.Required to answer.Single line text.

Answers

Answer:

4.8

Step-by-step explanation:

24/5 = 4.8

A rational number is any whole number, fraction, finite decimal or repeating decimal. Therefore 4.8 = rational number.

A rational expression to represent the amount of juice in each cup is 24/5.

What is a fraction?

A fraction is a part of the whole represented by a/b, where a and b are any integers.

Given, Kim divided 24 ounces of orange juice into 5 cups.

Therefore, the amount of juice in each cup is:

24/5

Hence, a rational expression to represent the amount of juice in each cup is 24/5.

The value of the function for x=-1 is 3.

The given function is [tex]f(x)=x^{5} +(x+3)^{2}[/tex].

What is a function?

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

From the table, we get coordinates as (-2, -31), (-1, y), (0, 9) and (1, 17).

To find the y value of the coordinate (-1, y), substitute x=-1 in the given function.

That is, [tex]f(-1)=(-1)^{5} +(-1+3)^{2}=3[/tex]

Therefore, option D is the correct answer.

Answers

Step-by-step explanation:

x + y = 2

Subtract x from both sides;

y = -x + 2

3x - 4y = 27

Substitute y;

3x - 4(-x + 2) = 27

Distribute;

7x - 8 = 27

Add 8 to both sides;

7x = 35

Divide both sides by 7;

Gershon lives 3 10 mile from the soccer fields. How far does Gershon walk if he walks from home to the soccer fields and back home? How many miles did he walk

Answers

Answer:

Gershon walked 620 mile

Step-by-step explanation:

From the question,

Gershon lives 310 mile from the soccer fields,

This means the distance from where Gershon lives to the soccer fields is 310 mile.

Likewise, the distance from the soccer fields to where Gershon lives his as well 310 mile.

So, if Gershon walks from his home to the soccer fields, he will cover a distance of 310 mile.

Then, if Gershon walks back home from the soccer fields, he will cover another distance of 310 mile.

Now, To determine how many miles he walked,

Total number of miles Gershon walked = The distance from where Gershon lives to the soccer fields + The distance from the soccer fields to where Gershon lives

Hence, Total number of miles Gershon walked = 310 mile + 310 mile

Total number of miles Gershon walked = 620 mile

Hence, Gershon walked 620 mile

The perimeter of the polygon is 4√(a² + b²).

Option D is the correct answer.

What is the distance between two points of a line?

The distance between two points of a line is given as:

Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

We have,

The polygon is formed by joining the four-point:

(0, b), (-a, 0), (a, 0), and (0, -b)

The distance between two points (x1, y1) and (x2, y2) is given by the formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Now,

Using this formula, we can find the lengths of the sides of the polygon:

The distance between (0, b) and (-a, 0) is d1.

= √[(0 - (-a))² + (b - 0)²]

= √(a² + b²)

The distance between (-a, 0) and (0, -b) is d2.

= √[(0 - (-a))² + (-b - 0)²]

= √(a² + b²)

The distance between (0, -b) and (a, 0) is d3.

= √[(0 - a)^2 + (0 + b)^2]

= √(a² + b²)

The distance between (a, 0) and (0, b) is d4.

= √[(0 - a)²+ (b - 0)^2]

= √(a² + b²)

The perimeter of the polygon is:

P = d1 + d2 + d3 + d4

= 4√(a² + b²)

Thus,

The perimeter of the polygon is 4√(a² + b²).
