Step-by-step explanation: This is what i can do

\(3\cdot \:4\div \:2=\\=12\div \:2=\\6\\\\4+16-10=10\\\\(1 + 2) + 3\times 4= \\=3+3\times \:4\\3+12 \\ =15\\\\\\\)

Order of Operations

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

First one: 3×4÷2

Since multiplication and division have the same power, you do the equation in order.

3×4=12

12÷2=6

Second one: 4+16-10

Since addition and subtraction have the same power, you do the equation in order.

4+16=20

20-10=10

Third one: (1+2)+3×4

You have to do the parentheses first...

1+2=3

Now you have to do multiplication since multiplication goes first (according to PEMDAS)

3×4=12

Now you have to add (3) and (12)

3+12=15

Final Answers

First one: 6

Second one: 10

Third one: 15

6=10=15

F.
$0 represents no gain and no loss

G.
$0 represents a loss

Answers

Answer:  B, E, and F.

Step-by-step explanation: -$300 means negative 300 which is not a gain, it is a loss as negative numbers are losses. So A is wrong. +400 indeed is a gain as it is a positive and has an addition sign in front of it Using this knowledge we can see that besides B, only E and F are correct.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.

Which one is right and why?

Answers

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

The answer for this is a

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

2 * (x + 18) ≥ 17

Step-by-step explanation:

2 times = 2 *

the sum of a number and 18 = (x + 18), where x is 'a number' because we don't know the value of 'a number'.

is at least 17 = ≥ 17, at least meaning at the minimum of 17 or higher.

When we piece this together, we get the outcome of;

2 * (x + 18) ≥ 17

Answer:

2(y + 18) ≥ 17

Step-by-step explanation:

2(y + 18) ≥ 17

2y + 36 ≥ 17  

     - 36   - 36

2y ≥ -19

/2    /2

y ≥ -19/2 or y ≥ -9.5

This means that y is great than or equal to -9.5

A circle with radius labeled 23 yards

Find the area for the circle (use 3.14 for pi). Show your work. Round to the nearest tenth.

Answers

Answer:

The area of the circle that has a radius of 23 yards will be 1,661.06 square yards.

What is the area of the circle?

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

Let r be the radius of the circle. Then the area of the circle will be

A = πr² square units

The radius of the circle is 23 yards. Then the area of the circle is calculated as,

A = π x (23)²

Simplify the equation, then the area of the circle is calculated as,

A = π x (23)²

A = 3.14 x 529

A = 1,661.06 square yards

The area of the circle that has a radius of 23 yards will be 1,661.1 square yards.
