QuestionFind the product. Write your answer as a fraction in simplest form.
$-\frac{4}{9}\left(-\frac{7}{9}\right)=$

Answers

Answer 1

Answer:

Answer:

28/81

Step-by-step explanation:

As you know, the product of fractions is the product of their numerators, divided by the product of their denominators. As with any product, the sign will be positive if there are an even number of minus signs among the factors.

(-4/9)(-7/9) = (4·7)/(9·9) = 28/81

June has 42 sports books, 85 mystery books, and 69 nature books. She arranged her books equally on 7 shelves. How many books are on each shelf.

Answers

Answer:

Step-by-step explanation:

We are given that

June has sports books=42

June has mystery books=85

June has nature books=69

Total number of shelves=7

We have to find the number of books are on each shelf.

Total number of books=42+85+69=196

To find the number of books on each shelf we will divide the total number of books by 7.

Number of books on each shelf= $(196)/(7)$

Number of books on each shelf=28

Hence, number of books on each shelf=28

Answer:

Step-by-step explanation:

Add 42, 85, and 69 together and you get 196 but you need to divide that by 7 and you get 28

A students' choir contains 25 children and only 5 of them play the piano. If a child is selected at random, what is the probability that the child DOES NOT play the piano? Select all the right answers.

Answers

Answer:

probability that the child DOES NOT play the piano

$P(E^(-)) =(4)/(5)$

Step-by-step explanation:

A students' choir contains 25 children

n(S) =25

The number of students play the piano =5

Let 'E' be the event of the child play the piano so n(E) =5

The probability of that the child play the piano

$P(E) = (n(E))/(n(S))$

$P(E) = (5)/(25)= (1)/(5)$

Let 'E⁻ be the event of the child play does not play the piano

$P(E^(-)) = 1- P(E)$

$P(E^(-)) = 1- (1)/(5) =(4)/(5)$

Conclusion:-

probability that the child DOES NOT play the piano

$P(E^(-)) =(4)/(5)$

Why does the LL theorem hold for proving right triangles congruent?

Answers

Triangles, considering congruent triangles, are generally composed of 2 sides and a hypotenuse. The hypotenuse is usually between these 2 sides. The best possible explanation is that the right angle is included between the legs. Using the "L" shape in the "LL" theorem, it is side then right angle then side to prove congruence between triangles.

We can see here that the LL theorem holds for proving right triangles congruent because it addresses the unique characteristics of right triangles. In a right triangle, one of the angles is a right angle, measuring 90°.

What is theorem ?

A theorem is a statement or proposition that has been proven to be true based on previously established facts, axioms, or other theorems. In mathematics, a theorem is a fundamental concept and plays a crucial role in the development and understanding of mathematical theories and principles.

The LL theorem, also known as the Leg-Leg Congruence Theorem, states that if two legs of one right triangle are congruent to the corresponding legs of another right triangle, then the two triangles are congruent.

If QR = 20 in., RS = 7 in., and SQ = 24 in., what is PN?

3 in.
7 in.
20 in.
24 in.

Answers

Answer: PN= 20 in.

Step-by-step explanation:

Given: In triangles PMN and QSR :

Length of P N ≅ Length of RQ (1) [ '≅' → Sign of congruence]

Length of QS ≅ Length of PM

Length of MN ≅ Length of RS

By SSS congruence rule

ΔPMN ≅ ΔQSR

Since Length of QR =20 in. [Given]

From (1)

Length of PN= 20 in. [Congruent means exactly equal]
