Can you ever use a calculator to determine if a number is irrational or rational?

Answers

Answer 1

Yes.

All rational numbers are either terminating or repeating decimals. This means that they either end or the decimal repeats the same digit or digits infinitely. An irrational number will never end and will not have a pattern to its digits.

5t+16=6-5t
I need help solving step by step

Answers

Equation: 5t+16=6-5t

Add 5t to both sides: 10t+16=6

Subtract 16 from both sides: 10t=-10

Divide by 10 from both side: t=-1

The solution of expression is,

t = - 1

We have to given that,

An expression to solve,

5t + 16 = 6 - 5t

Now, We can simplify as,

5t + 16 = 6 - 5t

Add 5t both side,

5t + 5t + 16 = 6 - 5t + 5t

10t + 16 = 6

Subtract 16 both side,

10t + 16 - 16 = 6 - 16

10t = - 10

Divide both side by 10,

t = - 10/10

t= - 1

Therefore, The solution is, t = - 1

Then compare the Notation's

823000. and 319000000.

319000000. is bigger than 823000.

So your answer is 319000000. so its United States.

what is 10 times as much as 50

Answers

ten times as much as fifty, or 10 * 50, is equal to 500

Final answer:

To find what is 10 times as much as 50, you multiply 50 by 10, which results in 500. This is a basic multiplication problem where the number 50 is increased by one order of magnitude.

Explanation:

The question 'what is 10 times as much as 50' involves a basic arithmetic operation known as multiplication. Multiplying a number by 10 is the same as adding a zero to the end of that number, when dealing with base ten numerical system. In this scenario, we are seeking to calculate 10 times 50, which can be expressed mathematically as:

Identify the two numbers involved in the multiplication: 10 (the multiplier) and 50 (the multiplicand).

Multiply the multiplicand by the multiplier: 50 × 10 = 500.

Therefore, 10 times as much as 50 is 500. This is consistent with the idea that a change from a power of ten to the next higher power means a ten-fold increase in value, or an increase by one order of magnitude.

Answers

0.5 meters Let's look at the problem and create an equation expressing it. "Greg had a rope one meter long" L = 1m "Greg and his friend Brad each cut off 0.2 meter of the rope to use in Greg's tree house." L = 1m - 0.2m - 0.2m "Greg cut off another 1/10 meter of the rope to use on a chair. " L = 1m - 0.2m - 0.2m - (1/10)m Now solve for L L = 1m - 0.2m - 0.2m - (1/10)m L = 1m - 0.2m - 0.2m - 0.1m L = 0.8m - 0.2m - 0.1m L = 0.6m - 0.1m L = 0.5m So the amount of rope left unused is 0.5 meters

According to statistics, a person will devote 37 years to sleeping and watching TV. The number of years sleeping will exceed the number of years watching TV by 19. Over the lifetime, how many years will the person spend on each of these activities? The person will spend X years watching TV and X years sleeping

Answers

s + w = 37
s = w + 19

w + 19 + w = 37
2w + 19 = 37
2w = 37 - 19
2w = 18
w = 18/2
w = 9 <=== 9 years watching t.v.

s = w + 19
s = 9 + 19
s = 28 <=== 28 years sleeping

Final answer:

A person will spend 28 years sleeping and 9 years watching TV if they devote 37 years combined to these activities with sleeping exceeding TV watching by 19 years.

Explanation:

To solve the problem of how many years a person will spend watching TV and sleeping given that the total is 37 years and the number of years sleeping exceeds watching TV by 19, we can use two variables X and Y where X represents the number of years spent watching TV and Y represents the number of years spent sleeping. Now, we know two things:

X + Y = 37 (since the total is 37 years)Y = X + 19 (since sleeping exceeds watching TV by 19 years)

Substituting the second equation into the first, we get:

X + (X + 19) = 37

2X + 19 = 37

2X = 37 - 19

2X = 18

X = 9

Now that we know X, which is the number of years watching TV, we can easily find Y, the number of years sleeping, by plugging X into the second equation:

Y = X + 19 = 9 + 19

Y = 28

Therefore, the person will spend 9 years watching TV and 28 years sleeping.

Factor expression 42x+49

Answers

Final answer:

To factor the expression 42x+49, we find the GCF which is 7, and express the expression as 7(6x + 7).

Explanation:

The question focuses on the task to factor the expression 42x+49. Factoring is a mathematical process in which we express a number or an algebraic expression as the product of its factors, which are usually simpler or more basic expressions.

To factor the given expression, we look for the greatest common factor (GCF) that both terms share. In this case, the GCF of 42x and 49 is 7. We factor the 7 out:

42x + 49 = 7(6x + 7)

The factored form is 7(6x + 7), which is the simplest form of the expression where 7 is a common factor multiplied by the binomial 6x+7.

Final answer:

The inequality that represents the scenario given, where one eighth of a number is less than or equal to 3, is X ≤ 24.

Explanation:

The problem given can be represented by an inequality. We are told that one eighth of a number is less than or equal to 3. We can express this in equation form as X/8≤3, where X is the unknown number we are trying to figure out.

To solve for X, we can perform the inverse operation of division on both sides of the inequality by multiplying by 8, following the principle of maintaining balance within an inequality. The inequality thus simplifies to X ≤ 24.

Hi there,

-2(5 + 6x) + 16 = -90
-10 - 12x + 16 = -90
6 - 12x = -90
- 12x = -90 - 6
-12x = -96

Hence, X = 8

first, distribute negative two to 5 and 6x. you should then have -10 • (-12x) + 16 =-90
after you get that follow order of operations. 120x + 16 = -90. next subtract 16 from both sides of the equation. 120x = -106.
