What is an arithmetic operation?

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.

It is given that,

Length of road = 9 miles

From the condition,

Mai ran 1/4 of the length of her road

Mai ran =  1/4 × length of her road

Mai ran =  1/4 × 9

Mai ran =  2.25 miles.

Thus, if the length of the road is 9 miles long and Mai ran 1/4 of the length of her road. Mai ran 2.25 miles.

A body is floating in seawater with 2/3 of its volume above the surface. The weight of the displaced water is?

Answers

Answer:

The weight of the displaced water is the weight of the body

Step-by-step explanation:

In situations like this, the volume of the displaced water is not important.

However, it should be noted that when a body is immersed (fully or partially) in a liquid, the weight of the displaced liquid is equal to the weight of the body immersed in the liquid.

Since the weight of the body is not given, I'll conclude that the displaced water has the same weight as the body floating on the water.

~ zachary

Answer:

[tex]d=\frac{\sqrt{97}}{6}\approx1.6415[/tex]

Step-by-step explanation:

We have the two points: (2, 5/2) and (8/3, 1).

And we want to find the distance between them.

So, we can use the distance formula:

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

Let (2, 5/2) be (x₁, y₁) and let (8/3, 1) be (x₂, y₂). Substitute:

[tex]d=\sqrt{(\frac{8}{3}-2)^2+({1-\frac{5}{2})^2[/tex]

Evaluate the expressions within the parentheses. For the first term, we can change 2 to 6/3. For the second term, we can change 1 to 2/2. So:

[tex]d=\sqrt{(\frac{8}{3}-\frac{6}{3})^2+({\frac{2}{2}-\frac{5}{2})^2[/tex]

Evaluate:

[tex]d=\sqrt{(\frac{2}{3})^2+(-\frac{3}{2})^2[/tex]

Square:

[tex]d=\sqrt{\frac{4}{9}+\frac{9}{4}[/tex]

Add. We can change 4/9 to 16/36. And we can change 9/4 to 81/36. So:

[tex]d=\sqrt{\frac{16}{36}+\frac{81}{36}}[/tex]

Add:

[tex]d=\sqrt{\frac{97}{36}}[/tex]

We can separate the square roots:

[tex]d=\frac{\sqrt{97}}{\sqrt{36}}[/tex]

Simplify. So, our distance is:

[tex]d=\frac{\sqrt{97}}{6}\approx1.6415[/tex]

A license plate is to have the following form: 4 letters followed by 4 numbers. How many different license plates can be made, assuming that letters and numbers can be reused?

Answers

Answer ≈ 4 and a half billion


If we assume your letters range from A to Z and your digits from 0 to 9, you have 26 possibilities per letter and 10 per digit. This gives you 26^4*10^4 which is roughly 4 billion and a half.

The number of different license plates that can be made will be 260⁴.

What are permutation and combination?

A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.

A license plate is to have the following form: 4 letters followed by 4 numbers.

We know that the total number of letters will be 26 (A to Z) and the total basic numbers will be 10 (0, 1, ..., 9).

The number of different license plates that can be made will be

⇒ 26 x 26 x 26 x 26 x 10 x 10 x 10 x 10

⇒ 26⁴ x 10⁴

⇒ (26 x 10)⁴

⇒ 260⁴

The number of different license plates that can be made will be 260⁴.

Stephen says that the numbers 38 and 40 are relatively prime. Explain why he is incorrect in making this statement. (make a good explanation plz)

Answers

Answer:

He is incorrect in this statement because 38 and 40 both have factors, other than 1 x itself. Prime numbers are numbers the only have 1 factor pair, and that is 1 x itself. Factors are the numbers you multiply to get the end result, and an example is 10x4=40. The factors of 40 are 8x5, 4x10, 2x20, and of course, 1x40. The factors of 38 are 2x19, and 1x38.

The definition of relatively prime is two numbers with a GCF of 1.The numbers 38 and 40 are not relatively prime.

The ratio of boys to girls in a classroom is 7 to 11. If there are a total of 49 boys in the classroom, then how many boys and girls are there all together?

Answers

Answer: 65

Step 1: Multiply and add until you get 49.

11 x 4 = 44.

44 + 5 = 49.

Step 2: Multiply and add until you get 26, because 7:11 to 49 boys is 26,       26 : 49.

7 x 3 = 21.

21 + 5 = 26.

Step 3: Add 26 and 49.

26 + 49 = 65

Answer:

126 students

Step-by-step explanation:

Boys : Girls

7 : 11

How do you get from 7 to 49?

49 ÷ 7 = 7

Therefore, you should multiply the number of boys by 7.

Multiply:

7 : 11

7 × 7 = 49

49 : 11

Remember that whatever we do to the left, do to the right.

Multiply:

49 : 11

11 × 7 = 77

49 : 77

Now, let's add the number of boys and girls in the class to find the total number of students.

Add:

49 + 77 = 126

Therefore, there are 126 students in all.

How do you write 1.65x10^8: 2x10^3 in scientific notation?

Answers

I'm guessing you're talking about the ratio,

(1.65 x 10⁸) / (2 x 10³)

You can cancel the lowest power of 10:

(1.65 x 10⁸) / (2 x 10³) = (1.65 x 10⁵) / 2

Divide 1.65 in half to get 0.825. So we have

(1.65 x 10⁸) / (2 x 10³) = 0.825 x 10⁵

Move the decimal point to the right, which involves multiplying by a factor of 10 which is taken from 10⁵, so we end up with

(1.65 x 10⁸) / (2 x 10³) = 8.25 x 10⁴

drag numbers to write an equation for the line in slope intercept form number is may be used once more than once or not at all

Answers

Answer:

y = -4x + 5

Step-by-step explanation:

The equation for the line, in slope-intercept form will take the following equation format which is y = mx + b.

Where,

b = y-intercept = 5 (this is where the line intercepts the y-axis, and also, x = 0 here)

m = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Use any two points on the line. Using (0, 5) and (1, 1), calculate m as follows:

m = [tex] \frac{1 - 5}{1 - 0} = \frac{-4}{1} = -4 [/tex]

Substitute m = -4, and b = 5 into y = mx + b.

y = -4x + 5
