A flat-screen television was marked down by 35 percent, which reduced its price by $115.65. What was the original cost of the television before it was marked down?
$214.78
$330.43

The price reduces by 0.35x.

This equals to 115.65

In arithmetic, variables look like

Answers

Answer:

In arithmetic, variables look like letters.

Step-by-step explanation:

As we know that Mathematical arithmetic deals with numbers and certain properties with them.

Some of the main properties between numbers are as follows:

AdditionSubtractionMultiplicationDivision

Variables do not remain constant, so we basically assign a number to a variable with an equal operator denoted by '='.

For example, let us assume a variable x being equal to 7. so it can written as:

[tex]x = 7[/tex]

Let suppose the value of the variable x=7 changes to x=10, then the new value will be:

[tex]x = 10[/tex]

Therefore, the correct answer is:

In arithmetic, variables look like letters.

A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly and at a constant rate. After 888 months, he weighed 138138138 kilograms. He started at 909090 kilograms.

Answers

Given :

Initial weight of sumo wrestler, I = 90 kg.

Final weight of sumo wrestler, F = 138 kg.

Time taken, T = 8 months.

To Find :

Weight gain per month.

Solution :

Weight gain per month = ( Final weight - Initial weight ) ÷ Total number of month

[tex]W = \dfrac{138-90 }{8}\ kg/month\\\\W = 6 \ kg/month[/tex]

Therefore, weight gain per month is 6 kg/month.

Hence, this is the required solution.

A gym charges $8.75 for each swimming class and a one-time registration fee of $12.50. A student paid a total of $56.25. How many swim classes did the student take?

Answers

Answer:

He took 5 swimming classes.

Step-by-step explanation:

The problem states that the student paid a total of $56.25 for the classes and also the one-time registration fee. To find the number of classes, we should first subtract the one-time registration fee from the total.

$56.25 - $12.50 = $43.75

Now that we know he spent a total of $43.75 on the classes without the registration fee, we can divide that number by the cost of one class ($8.75) to calculate the total number of classes he took.

43.75 / 8.75 = 5

Answers

Answer:

x = - 1

Step-by-step explanation:

Given

f(x) = x³ + x² + x + 1

If x = 1 is a factor then f(1) = 0

f(1) = 1³ + 1² + 1 + 1 = 4 ≠ 0 , thus x = 1 is not a zero

f(- 1) = (- 1)³ + (- 1)² + (- 1) + 1 = - 1 + 1 - 1 + 1 = 0

Thus x = - 1 is the only zero

You have quarters. You find ​% more quarters in your room. Then you go shopping and spend ​% of the total number of quarters. Write an expression to represent the total number of quarters you take with you shopping.​ Calculate, in​ dollars, the amount of money you have left.

Answers

Complete question :

You have 20 quarters. You find 40% more quarters in your room. Then you go shopping and spend 50% of the total number of quarters.

A. Write an expression that represents the total number of quarters you take with you when you go shopping.

B. How much money do you have left?

Answer:

[20 + (0.4*20)] = 28 quarters

$3.5

Step-by-step explanation:

Given that:

Initial number of quarters = 20

Quarters in room = 40%

Hence, Numbe of quarters in room = 0.4 * 20 = 8

Total number of quarters taken for shopping :

(Initial amount + Numbe of quarters in room)

(20 + 8) = 28 quarters

50% of quarters was spent on shopping :

0.5 * 28 = 14 quarters

Total left :

28 - 14 = 14

Quarters left in dollars :

1 quarter = 25 cent = 0.25 dollars

14 * $0.25 = $3.5

Is 5/6 equal to 2/3?

Answers

Answer: They are not equal

=====================================================

Work Shown:

For now, let's assume they are equal. We'll show a contradiction happens.

5/6 = 2/3

5*3 = 6*2 ... cross multiply

15 = 12 ... here's the contradiction

If the original equation was true, then we would get the same thing on both sides in the final step shown above. However, we get a contradiction, so that means the original equation is false.

Furthermore, the left side is larger in the third step, so the left side is larger for each of the three steps. We can then say

5/6 > 2/3

5*3 > 6*2

15 > 12

Which helps show 5/6 is larger than 2/3.

---------------------

Or you can use a calculator to see that

5/6 = 0.833 approximately

2/3 = 0.667 approximately

which shows the two fractions aren't equal and 5/6 is larger.

Given that a = -1, b=2 and c= -3 ,find the value of a(b2+c2)

Answers

Answer:

a([tex]b^{2}[/tex]+[tex]c^{2}[/tex]) = = -13

Step-by-step explanation:

Given that a = -1, b=2 and c= -3

find the value of a([tex]b^{2}[/tex]+[tex]c^{2}[/tex])

Just substitute the values given for each variable

a([tex]b^{2}[/tex]+[tex]c^{2}[/tex]) = (-1)([tex]2^{2}[/tex]+[tex](-3)^{2}[/tex]) ; do the exponents first

a([tex]b^{2}[/tex]+[tex]c^{2}[/tex]) = (-1)(4+9)=(-1)(13) ; now add inside the parenthesis;

a([tex]b^{2}[/tex]+[tex]c^{2}[/tex]) = -13 ; and multiply by -1

If 45% of a number is 63 and 35% of the same number is 49, find 80% of that number.

Answers

Answer:

Step-by-step explanation:

1) Let the number be y

45%of y=63

45y/100=63

Y=6300/45

Y=140

So 80%of a number =80y/100

=80×140/100

=112.

Let the number be y

35%of y=49

35y/100=49

Y=4900/35

Y=140

So 80%of a number =80y/100

=80×140/100

=112.
