Which of the following can be used to prove that triangle ABC is congruent to triangle DEF?

Answer:

I think B sorry if wrong

Answer:

It is b

Step-by-step explanation:

Like I said in the previous answer the direction of the "<" sign can tell you, and since it is the " < or equal to " sign it is a solid line not dotted. So therefore its b.

The square root of 89 is an irrational number with never-ending digits

Solution :

Real numbers :

Real numbers are the sets of rational numbers and irrational numbers taken together

Irrational numbers:

Irrational numbers are the set of all numbers that are not rational; they cannot be written as either a terminating or repeating decimal; they cannot be expressed as a fraction of two integers.

or,

The set of irrational numbers is the set of numbers that are not rational, are non repeating, and are non terminating. Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers. The denominator q is not equal to zero (q ≠ 0). Also, the decimal expansion of an irrational number is neither terminating nor repeating.

1)65.555

Statement:65.555....is rational and a repeating decimal

2)-57

Statement: It is a negative integer.

3)[tex]\sqrt{89}[/tex]

Statement:

Due to the nature of its non-repeating and non-terminating decimal expansion, the square root of 89 cannot be written in the form of p/q, hence, it is an irrational number.

The value of the square root of 89 in decimal form is 9.433981.. so on, The square root of a number can have two values, a positive and a negative value. So, √89=+9.433981. Hence, The square root of 89 is an irrational number with never-ending digits.

Step 1: Divide the number 89 by 9, (because 92 =81 is a perfect square number just less than 89).

Step 2: The divisor and the quotient need to be the same numbers; in this case, it is 9. Multiply the quotient and the divisor and subtract the result from 89.

Step 3: For the next divisor, add the previous divisor with the quotient. (9 + 9 = 18); place it as the new divisor with a blank on its right.

Step 4: Put a decimal after the quotient '9' and bring down two zeros to place it after 8 so that it becomes 800. (184 × 4 = 736). Subtract 736 from 800.(800 − 736 = 64)

Step 5: Bring down another pair of zeros and place it after 64, so that it becomes 6400. Take the new quotient 4 and add it to 184. (184 + 4 = 188)

Step 6: Repeating the above steps, we need to fill the blank with a number such that when the new divisor is multiplied by the new quotient, the product is less than or equal to the dividend 6400. (1883 × 3 = 5649)

Step 7: Write the same number after 4 in the quotient. Subtract 5649 from 6400. (6400 − 5649  = 751)

Step 8: Repeat the process until we get the remainder equal to zero. The square root of 89 up to two places is obtained as 9.43 by the long division method.

Answer:

it is an isosceles triangle

Step-by-step explanation:

the two sides of the triangle are equal in length, also the angles opposite to the equal sides are equal. so, it is called as isosceles traingle

Solve for x

|2x -4| + 6 =8

subtract 6 from both sides, then solve

|2x - 4| = 2                                   and                                 |2x -4| = -2

2x - 4 = 2                                                                           2x - 4 = -2

     +4   +4                                                                                +4  +4

2x = 6                                                                                   2x = 2

divide by 2 to isolate the variable

x = 3                                                                                    x = 1

Subtracting the index forms gives 5. 218  × 10^8 . Option D

Index form is defined as the exponent or power of a number or variable.

Given the index forms;

(5.3 x 108) − (8.2 x 106)

To subtract, the index forms must have the same exponential values

5.3 x 10^8 - 0. 082 × 10^8

(5. 3 - 0. 082) × 10^8

Subtract the decimals

5. 218  × 10^8

Thus, subtracting the index forms gives 5. 218  × 10^8 . Option D

Answer:

[tex]\boxed{\bold{y}}[/tex]

Explanation:

(See Image Below)

We can see the sequence A in the picture. Each term is more then the previous term and each term is the previous term multiplied by 2. (Aₙ=n-1 and Bₙ=2ⁿ⁻¹).

Given that,

We can see in the picture.

We have to describe how to create each new word from the prior term in sequence A.

From the 4 option

Option 1 is true because in the picture we can see each term is the previous term multiplied by 2.

Option 4 is true because in the picture we can see that each term is more then the previous term.

From row 1 and row to 2 in the picture we can say that.

We can say Aₙ=n-1 and Bₙ=2ⁿ⁻¹

Therefore, we can see the sequence A in the picture.
