How To Find X+y?(Explain Pls, Thank You!

Answers

Answer 1

The value of x+y is 289

What is an expression?

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.

Given is an expression, x²+74x+2021=y²

On solving, we get

x²+2×37x + 37² = y²-652

(x+37)²= y²-652

(x+37)²- y² = -652

(x+y+37) (x-y+37) = 289 × -2

Thus, x+y+37 = 289......(i)

x-y+37  = -2.......(ii)

Solving the equations, we get

x = 125 & y=164

Therefore,

x+y = 125+164

= 289

Hence, The correct answer is x+y = 125+164 = 289

Answers

Answer:1/5

Step-by-step explanation:

The probability the fish weighs at least 12 ounces is 1/5. Probability has several uses in games.

What is probability?

The chances of an event occurring are defined by probability. Probability has many uses in games, in business to create probability-based forecasts.

The given data in the problem is;

A fish tank at a hatchery contains = 25 fish

Fish weighs at least 12 ounces=5

probability the fish weighs at least 12 ounces=?

The probability the fish weighs at least 12 ounces is ;

[tex]\rm P = \frac{Favourable \ event }{Total\ event} \\\\ \rm P = \frac{5}{25} \\\\ P=\frac{1}{5}[/tex]

The probability the fish weighs at least 12 ounces Will be 1/5.

Tell whether the angles are adjacent or vertical. Then find the value of x. The angles are . Question 2 x=

Answers

Answer:

Adjacent

x = 14

Step-by-step explanation:

Find the diagram attached

Adjacent angles places side by side and can also be on the same straight line. Since 5x and x+96 are on the same straight line ans placed side by side, then the angles are adjacent.

The sum of angle on a straight line is 180 degrees, hence;

5x + x+ 96 = 180

6x = 180 - 96

6x = 84

x = 84/6

x =14

The value of x s 14

How do you find cubic root?? Theres not a specific question, I just need to know.

Answers

Answer and Step-by-step explanation:

Picture this:

There is a base number, and when this number gets multiplied by itself 3 times, we say the number got cubed.

To find the cubic root, we find the number that had to multiply itself 3 times that got the bigger number.

Example:

Let's say we are given the number 27.

If we take the cube root of 27, we get 3.

[tex]\sqrt[3]{27}[/tex] = 3

This is because 3 times itself 3 times is 27.

3 × 3 × 3 = 27

9 × 3 = 27

27 = 27

Another Example:

We are given the number 970299.

If we put this into a calculator and press the button to do this: [tex]\sqrt[3]{x}[/tex], then, in some calculators, it would look like this: [tex]\sqrt[3]{972099}[/tex]

We we click to solve, we get that base number, or the cubed root, to be 99.

That means 99 was multiplied by itself 3 times to get 972099.

3/8 were non fiction, or 24

1/4 (2/8) were picture books, or 16

5/8 were non fiction or picture books, so ’the rest‘ of the chapter books is 3/8.

3/8 were chapter books, or 24.

add the amount of picture books and chapter books since they are the fictional texts.

16+24=40

subtract the amount of non fictional books from the amount of fictional books to get the sum.

40-24=16
