Long-term purchase on a credit card better than taking out a loan when interest rate is 0% or very lower than loan, or any other benefits

We can use a credit card for long term purchases if there is a 0% interest rate on purchase is allowing you to pay off your shopping with no additional cost for an introductory period. Or some of the credit cards may offer interest-free purchases for 3 to 6 months others can run for as long as 12 to 14 months. An interest-free period could be considered long-term if it lasts between 12 and 14 months or more.

We could benefit from one of these cards if you are making a large purchase and need more breathing room to pay it off without any interest. This is especially useful if you have a high spending period such as an overseas holiday coming up.

A long  term purchase with loan or with a credit card will depends upon the interest rates offered in both the schemes.

In order to understand that what is more beneficial for us a long term purchase or taking out a loan we have to see the interest rates of the both the schemes.

If the interest  rate of loan is higher than the interest rate offered by credit card then we must go for long term purchase on credit card and the amount can be paid later .

Also credit cards often offer other benefits too. These options can also be seen as a determining parameters of whether to take loan or a long term purchase on credit card is beneficial.

Also we can have a look at the period of interest free purchase offered by the credit card.

Depending upon the credit card and its usage they can vary from three months to one year with multiple other benefits which promote the use of credit card.

so we can conclude that

A long  term purchase with loan or with a credit card will depends upon the interest rates offered in both the schemes.

Answer:

Multiply the entire expression by the radical denominator. This keeps the expression equal and makes the denominator 3, a whole number.

Step-by-step explanation:

The denominator is irrational because it is a radical number, √3.

To rationalize the denominator, multiply the entire expression by √3. The denominator will become a whole number. This works because you multiply top and bottom by the same value.

[tex]\frac{3 + \sqrt{2} }{\sqrt{3}}[/tex]

[tex]= \frac{(\sqrt{3})(3 + \sqrt{2}) }{(\sqrt{3})(\sqrt{3})}[/tex]

[tex]= \frac{(\sqrt{3})(3 + \sqrt{2}) }{3}[/tex]  

√3 X √3 = 3 because:

√3 X √3 = √3²

Squaring a number and also finding its square root are opposites, or reverse operations. They cancel out

You probably need to simplify the rest of the equation too.

[tex]\frac{(\sqrt{3})(3 + \sqrt{2}) }{3}[/tex]

[tex]= \frac{3(\sqrt{3}) + (\sqrt{2})(\sqrt{3})}{3}[/tex]  Distribute over brackets

[tex]= \frac{3(\sqrt{3}) + \sqrt{2*3}}{3}[/tex]   Simplify

[tex]= \frac{3(\sqrt{3}) + \sqrt{6}}{3}[/tex]

Some people use a more simplified version whether they simplify each term in the numerator:

[tex]\frac{3(\sqrt{3}) + \sqrt{6}}{3}[/tex]    (3√3)÷3 = √3

[tex]\sqrt{3} + \frac{\sqrt{6}}{3}[/tex]

Answer:

a) Hence the Baby Manatee is 4 feet long.

b) Hence the Length of blue whale is 108 feet.

Step-by-step explanation:

Given:

Length of Mother manatee = 12 feet.

Now given that:

A mother  manatee is three  times as long as her baby manatee.

Let the length of baby manatee be 'x'.

So equation can be framed as

[tex]3x=12[/tex]

hence the equation is [tex]3x=12[/tex].

Solving the equation we get;

Dividing both side by 3 using Division property of equality we get;

[tex]\frac{3x}{3}=\frac{12}{3}\\ \\x=4\ feet[/tex]

a) Hence the Baby Manatee is 4 feet long.

Solving for part b we get;

Given:

If a blue whale is 9 times as long as the  mother manatee

Hence equation can be framed as;

Length of blue whale is = [tex]9 \times \textrm{Length of Mother manatee}[/tex]

Length of blue whale is = [tex]9\times 12 =108\ feet[/tex]

b) Hence the Length of blue whale is 108 feet.

We will subtract 13 from the days of March to find out the days in March Ron will be in Seattle.

Step-by-step explanation:

Given,

Number of days Ron will be in Hawaii = 13 days

Number of days in March = 30 days

As Ron will be in Hawaii for 13 days, the remaining days he will be in Seattle.

So we will subtract 13 from days of March to find out the number of days in March, Ron will be in Seattle.

Number of days in Seattle = Days of March - Number of days in Hawaii

Number of days in Seattle = 30 - 13 = 17 days

We will subtract 13 from the days of March to find out the days in March Ron will be in Seattle.

t = 51°

Step-by-step explanation:

The total sum of a polygon's exterior angles is always 360°.

Add all of the given angles and equate it to 360°.

40° + 34° + 34° + 46° + (2t - 50°) + (2t - 50°) + 2t = 360°     Collect like terms

154° + 2t - 50° + 2t - 50° + 2t = 360°    Remove brackets and collect like terms

54° + 6t = 360°   Isolate t by doing reverse operations in reverse BEDMAS

6t = 360° - 54°    Subtract 54° from both sides

Answer:

Step-by-step explanation:

consecutive numbers are one right after the other...

ur 3 consecutive numbers are :

x and x + 1 and x + 2.....and they total 84

x + x + 1 + x + 2 = 84.....combine like terms

3x + 3 = 84

3x = 84 - 3

3x = 81

3x = 81/3

x = 27

x + 1 = 27 + 1 = 28

x + 2 = 27 + 2= 29

so your 3 numbers are 27,28,29 with the lowest being 27

Answer: 24

Step-by-step explanation: This problem states that the sum of 3 consecutive numbers is 84 and it asks us to find the smallest number.

3 consecutive numbers can be represented as follows.

X ⇒ first number

X + 1 ⇒ second number

X + 2 ⇒ third number

Since the sum of our 3 consecutive numbers is 84, our equation will read X + X + 1 + X + 2 = 84.

Simplifying on the left we get 3x + 3 = 84.

Subtracting 3 from both sides, we have 3x = 81.

Now we can divide both sides by 3 to get x = 27.

This means that 27 will be the smallest number.

Answer:

C

Step-by-step explanation:

First: work out the difference (decrease) between the two numbers you are comparing.

Decrease = Original Number - New Number

Then: divide the decrease by the original number and multiply the answer by 100.  

% Decrease = Decrease ÷ Original Number × 100

If your answer is a negative number then this is a percentage increase.

Thus, the answer is a 86.7% (rounded) increase.

Final answer:

The sale of KIDZ sneakers increased by $1.3 billion, representing an 86.7% increase when rounded to the nearest tenth of a percent.

Explanation:

To find the percent of increase for the sale of KIDZ sneakers, we subtract the original amount ($1.5 billion) from the new amount ($2.8 billion) and then divide by the original amount. The difference between the two values is $2.8 billion - $1.5 billion = $1.3 billion. To calculate the percentage increase, we divide $1.3 billion by $1.5 billion, which gives us approximately 0.8667. To get the percentage, we then multiply by 100, resulting in an 86.67% increase. Finally, rounding to the nearest tenth of a percent, we get an increase of 86.7%.

Answer:

The mural in David's drawing is 4 cm long.

Step-by-step explanation:

Given:

David made a scale drawing of a mural he is going to paint.

He used a scale of 1 cm=4ft.

If the actual mural will be 16 feet long.

Now, to find how long is the mural in David's drawing.

Let the length of mural in David's drawing be [tex]x\ cm[/tex].

So, as given 1 cm = 4 ft.

1 cm is equivalent to 4 ft.

Thus, [tex]x\ cm[/tex] is equivalent to 16 feet.

Now, to get the length of mural in David's drawing by using the cross multiplication method:

[tex]\frac{1}{4} =\frac{x}{16}[/tex]

By cross multiplication:

[tex]16=4x[/tex]

Dividing both sides by 4 we get:

[tex]4=x[/tex]

[tex]x=4\ cm.[/tex]

Therefore, the mural in David's drawing is 4 cm long.

Subtract

True options:

1. The vertex of the function is at (1,–25).

5. The graph is negative on the entire interval –4 < x < 6.

Step-by-step explanation:

Part of the graph of the function f(x) = (x + 4)(x – 6) is shown in attached diagram.

This graph intesects the x-axis at points (-4,0) and (6,0). So, the x-coordinate of the vertex is \dfrac{-4+6}{2}=\dfrac{2}{2}=1

The y-coordinate of the vertex is

y=(1+4)(1-6)=5\cdot (-5)=-25

Hence, the vertex is ar the point (1,-25) - frist option is true, second option is false.

For all x<1 the graph is decreasing, for all x>1 the graph is increasing. So, third option is false.

The graph is positive (placed above the x-axis) for all x<-4 or x>6. This means fourth option is false.

The graph is negative (placed below the x-axis) for all -4<x<6. This means fifth option is true.

So, coordinates of circumcenter is [tex](4,-1)[/tex]

The force of gravity acting on the block(and weight) in the air is 2403.45 newton

Step-by-step explanation:

Density of an object is defined as the ratio of mass to volume

So we can write it as:

[tex]d = \frac{m}{V}[/tex]

And the force is given by:

[tex]F_g = mg[/tex]

We know that

d = 3500 kg/m^2

V = 0.07 m^3

g = 9.81 ms^-2

So we will calculate the mass first

[tex]d = \frac{m}{V}\\3500 = \frac{m}{0.07}\\m = 3500*0.07\\m = 245\ kg[/tex]

Now,

[tex]F_g = 245 * 9.81\\= 2403.45\ N[/tex]

Slope = - 3, y-intercept is 4 and the equation is y = - 3x + 4.

Step-by-step explanation:

Slope of a straight line passing through two given points [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] is given by the formula

[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex].

Now, the given graph of the straight line passes through the points (0,4) and (1,1) points.

Hence, the slope of the straight line will be = [tex]\frac{1 - 4}{1 - 0} = - 3[/tex]

Again, the straight line intersects the y-axis at point (0,4) point. hence, its y-intercept is 4.
