Evaluate xy for x = –9 and y = 5.
A –4
B 45
C –45
D –14

Answers

Answer 1

Answer:

C

Step-by-step explanation:

9 times 5 is 45. when ur multiplying and there's only one negative sign, the answer will always be negative.

Answer 2
C. -45

These types of problems can be fairly simply once you understand substitution. Substitution is when we put in values (in this case -9 and 5) in their set variable (x and y in this case.)

The problem states that x=-9 therefore we put in -9 for x in the multiplication of xy so it looks like this: (-9)(y). Next we want to substitute in the y value which is 5 so that we now have (-9)(5).

Because there is no plus or minus sign, along with a division sign, we then MULTIPLY these two numbers because the variables are connected so -9*5 would equal to -45.

How many quarts, rounded to the nearest tenth, are in 50 liters

Answers

About 52.83 quarts are in 50 liters.
Rounded to the nearest tenth is 52.8
So 52.8 would be your answer.

The amount in quarts in 50 liters rounded to the nearest tenth is; 52.8 quarts.

According to the question;

There are 50 liters and we are required to determine how many quarts there are rounded to the nearest tenth.

The conversion factor of liter to quarts is; 1.057 quarts per litre.

In essence;

1 liter is equal to 1.057 quarts.

Therefore, 50 liters is equivalent to;

50× 1.057 quarts

Therefore, 50 liters = 52.83 quarts.

By rounding off to the nearest tenth; 52.83 quarts = 52.8 quarts.

Step-by-step explanation:

Add the 3/4 to cross it out on the left side and whatever you do to one side you do to the other side. so you add 3/4 or .75 on to 10 to get 10.75.

k-3/4=10

k=10.75

Subtract the 5/7 from the Z and subract it from -3 to get, -3.71.

Z+5/7=-3

Z=3.71

Subtract 9 from the left side and subtract 9 from the right side.

9+t/12=-3

t/12=-12

Then you would multiply by 12 from the left side and multiply by 12 from the right side.

t/12=-12

t=-144

Which statement is true?

A rational number must show repeating digits after the decima
A rational number must show terminating digits after the decimal
An irrational number cannot be written as a repeating decimal.
An irrational number may show terminating digits after the decimal

Answers

Answer:

An irrational number may show terminating digits after the decimal

Step-by-step explanation:

Examples of Rational Numbers

Number 9 can be written as 9/1 where 9 and 1 both are integers.  0.5 can be written as ½, 5/10 or 10/20 and in the form of all termination decimals.  √81 is a rational number, as it can be simplified to 9 and can be expressed as 9/1.  0.7777777 is recurring decimals and is a rational number

Examples of Irrational Numbers

Similarly, as we have already defined that irrational numbers cannot be expressed in fraction or ratio form, let us understand the concepts with few examples.

5/0 is an irrational number, with the denominator as zero.

π is an irrational number which has value 3.142…and is a never-ending and non-repeating number.

√2 is an irrational number, as it cannot be simplified.

0.212112111…is a rational number as it is non-recurring and non-terminating.

There are a lot more examples apart from above-given examples, which differentiate rational numbers and irrational numbers.

Properties of Rational and Irrational Numbers

Here are some rules based on arithmetic operations such as addition and multiplication performed on the rational number and irrational number.

#Rule 1: The sum of two rational numbers is also rational.

Example: 1/2 + 1/3 = (3+2)/6 = 5/6

#Rule 2: The product of two rational number is rational.

Example: 1/2 x 1/3 = 1/6

#Rule 3: The sum of two irrational numbers is not always irrational.

Example: √2+√2 = 2√2 is irrational

2+2√5+(-2√5) = 2  is rational

#Rule 4: The product of two irrational numbers is not always irrational.

Example: √2 x √3 = √6 (Irrational)

√2 x √2 = √4 = 2 (Rational)

The solution of the expression for the value of t will be t = ( 12s -3r +31) / 3rs.

What is an expression?

Numeral variables and operations marked by the signs for addition, subtraction, multiplication, and division are combined in the mathematical equation.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented using mathematical symbols. They can also signify other characteristics of logical grammar, such as the operation order.

Given expression is 4r+3trs-3u+2=12s+r-1. the value of t for the expression will be solved as:-

4r+3trs-3u+2=12s+r-1,

3trs = 12s - 4r +r + 34 -2 - 1

3trs = 12s - 3r + 31

t = ( 12s -3r +31) / 3rs

Therefore, the solution of the expression for the value of t will be t = ( 12s -3r +31) / 3rs.
