How many 4 1/2 meters of ribbon are there in a 140 meter spool?​

Answer:

5 12/25

Step-by-step explanation:

The first step is to separate the whole number number from the decimal.

that would be 5

Next would to see in which place the decimal number is in. .48 is in the hundredths place so we put 48 over 100 like this 48/100

So now we have the whole number 5 and the fraction 48/100

Lastly we simplify the fraction. 48 divided by 2 and 100 divided by 2

This equals 24/50

This can be simplified even more

24 divided by 2 and 50 divided by 2

This equals 12/25

Then we put the whole number in front and your final answer is

5 12/25

Answer:

First number 2

Second number 1

Step-by-step explanation:

Let the first number = x

Let the second number = 3x - 5

Equation

x + 3x - 5 = 3                    

Solution

x + 3x- 5 = 3                   Combine

4x - 5 = 3                        Add 5 to both sides

4x - 5 + 5 = 3 + 5           Combine

4x = 8                              Divide by 4

4x/4 = 8/4                       Combine

x = 2

3x -5 = 3(2)- 5 = 1

Answer:

The list of angle of rotation is zero

Step-by-step explanation:

* Lets revise some definitions about isosceles trapezoid

- An isosceles trapezoid is a trapezoid with congruent base angles

- An isosceles trapezoid has congruent legs

- An isosceles trapezoid has 1 axis of symmetry

- An isosceles trapezoid has no rotational symmetry

* Lets solve the problem

- From the attached figure:

∵ The figure is quadrilateral

∵ The quadrilateral has only a pair of parallel sides

∵ The parallel side not equal in length

∵ The other two sides of the quadrilateral are equal in length

∴ The quadrilateral is an isosceles trapezoid

∵ The isosceles trapezoid has no rotational symmetry

∴ There is no angle of rotation

∴ The list of angle of rotation is zero

Answer:

x = - 3 and x = 1

Step-by-step explanation:

Given the rational expression

[tex]\frac{x}{x^2+2x-3}[/tex]

The denominator of the expression cannot be zero as this would make the expression undefined. Equating the denominator to zero and solving gives the values that x cannot be, that is

x² + 2x - 3 = 0 ← in standard form

(x + 3)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 1 = 0 ⇒ x = 1

Thus x = 1 and x = - 3 are both excluded values

Answer:

yes

Step-by-step explanation:

Let's go through the steps.

d/5 +12 = -15

1. Multiply both sides by 5.

Doing this we get:

d + 60 = - 75

2. Subtract 60 from both sides.

d = - 75 - 60

d = -135

Step 2 above is the final step taken to find the value of d.

Answer:

90

Step-by-step explanation:

Divide the larger number by the smaller number

If the remainder is zero then the larger number is the LCM

If not repeat with multiples of larger number

90 ÷ 15 = 6 remainder 0

Since remainder is 0 then 90 is the LCM of 15 and 90

Answer:

= -46

Step-by-step explanation:

Since, it is below zero, it is in the negatives. Therefore, it is -46.

Answer:

-46

Step-by-step explanation:

Anything below zero is going to be a negative integer. Your problem asks to write an integer to represent 46 degrees below zero. So, we would write the number 46 with the negative symbol, which is ( - ). There for the correct answer would be -46.

Here are some other examples:

54 degrees below zero  →  -54

negative 120  →  -120

16 degrees below zero  →  -16

Answer:

The simplest form of the expression is 16 a²b²

Step-by-step explanation:

* Lets explain how to solve the problem

- To simplify any fraction with exponent you must put it with positive

 exponent

- Ex: the fraction [tex](\frac{2}{3})^{-1}[/tex] not in the simplest form

 because it has negative exponent

- To change the negative exponent to positive exponent reciprocal the

 fraction, [tex](\frac{3}{2})^{1}[/tex] and this is the simplest form of the fraction

* Now lets solve the problem

∵ The expression is [tex](\frac{1}{4ab})^{-2}[/tex], where a and b ≠ 0

- At first reciprocal the fraction

∴ [tex](\frac{1}{4ab})^{-2}=(\frac{4ab}{1})^{2}[/tex]

- Then solve the power

∵ 4² = 16

∵ (ab)² = a²b²

∴ (4ab)² = 16 a²b²

* The simplest form of the expression is 16 a²b²

Answer:

No, 2.171m.

Step-by-step explanation:

Add all of measurements. 3.52+17.3+27.009=47.829

Compare 2 numbers.

47.829<50

So she needs more ribbon,because the length she has is less the requirement, 50m.

Find the difference(the length she needs).

50-47.829=2.171

Answer:

x = 10/19

Step-by-step explanation:

[tex]log(x)-log(2x-1) = 1\\log\frac{x}{2x-1}=log(10)\\\frac{x}{2x-1}=10\\x = \frac{10}{19}[/tex]

The solution to the equation log x - log(2x-1) = 1 is x = 10/19.

We have,

To solve the equation log x - log(2x-1) = 1, we can use logarithmic properties to simplify the equation.

First, we can apply the quotient rule of logarithms, which states that

log a - log b = log(a/b).

Applying this rule to the equation, we get:

log(x / (2x-1)) = 1

Next, we can rewrite the equation in exponential form, using the definition that log base a of b is equivalent to a raised to the power of the logarithm equals b.

In this case, the base is 10 since we are using common logarithms (log base 10):

[tex]10^1[/tex] = x / (2x-1)

Simplifying the left side, we have:

10 = x / (2x-1)

To eliminate the denominator, we can multiply both sides of the equation by (2x-1):

10(2x-1) = x

Expanding the left side:

20x - 10 = x

Now, we can isolate the variable x:

20x - x = 10

19x = 10

Dividing both sides by 19:

x = 10/19

Therefore,

The solution to the equation log x - log(2x-1) = 1 is x = 10/19.

Answer:

1. The value is 50,000 The value in the ten thousands place is different than the place value of the thousands place by a power of 10.

Step-by-step explanation:

The value in the ten thousands place for the Big Roller Coaster tickets is 5, which is ten times greater than the value in the thousands place, also 5, due to the base-10 number system.

The value of the ten-thousands place for the number of tickets sold for the Big Roller Coaster, which is 255,429, is 5. This is obtained by looking at the digit in the second place from the left.

The value of the tens place is different from the value of the thousands place because each place represents a different power of 10.

In the number 255,429, the number in the thousands place is 5, which actually represents 5,000 (5 x 1,000), while the number in the ten thousands place is also 5, but it represents 50,000 (5 x 10,000).

Thus, the value in the tens place is ten times greater than the value in the thousands place in the base-10 number system.

The specified expression simplifies to -r² + r - 44. Steps to find equivalent expressions include gathering like terms and utilizing the distributive property.

The expression (2r²+r-1) – (3r²+48-5) can be rewritten as 2r²+r-1 - 3r² - 48 +5. For the r² terms, combine 2r² and -3r² to get -r². For the constant terms, combine -1, -48 and +5 to get -44. And there's only one r term which is r. Together, these give the equivalent expression as -r² + r - 44.

#SPJ12

The expression equivalent to (2r2 + r - 1) - (3r2 + 48 - 5) is -r2 + r - 44.

To find the equivalent expression, we need to distribute the negative sign into the second set of parentheses.

Then, combine like terms.

The expression becomes: (2r2 + r - 1) - 3r2 - 48 + 5.

Combining like terms further, we have: 2r2 + r - 1 - 3r2 - 48 + 5

Now, combine the like terms again: (2r2 - 3r2) + r + (-1 - 48 + 5). Simplifying this gives us: -r2 + r - 44

Therefore, the expression equivalent to (2r2 + r - 1) - (3r2 + 48 - 5) is -r2 + r - 44.
