Answer:

x = 12√2

Step-by-step explanation:

if its a square, all sides similar of 12 units.

then the bottom and side length is 12 units

we need to find x, the diagonal.

formula: a²+b² =c²

            : 12² + 12² = c²

            : c = √144+144

            : c = √288

            : c = 12√2

Therefore diagonal, x is 12√2

Solution,

CP of a bicycle=$3000

Marked up=40%

Now,  

→40% of $3000

→40/100x$3000

→$1200

→$3000+$1200=$4200

Again,

Discount(d)=30%

→30%of $4200

→30/100x$4200

→$1260

Hence, the discount price of the bicycle is $1260

Step-by-step explanation:

The discount price of the bicycle will be $1260.

One of a company's financial accounts, an income statement or profit and loss account, lists the company's revenues and costs for a specific time period. It describes the process through which revenues are converted into net income or net profit.

Given that Great Escape bought a vintage bicycle for $3,000. They marked it up

The discounted price of the bicycle will be calculated as:-

Marked up=40%

40% of $3000

40/100x$3000

$1200

$3000+$1200=$4200

Now discount of 30%.

30%of $4200

30/100x$4200

$1260

Hence, the discount price of the bicycle is $1260.

Step-by-step explanation:

(-1)(6x-7y=-20)

-6x+7y=20

so now you can eliminate one term

6x+5y=4

-6x+7y=20

12y=24

y=2

plug y back into one equation to find x

6x+5(2)=4

6x+10=4

6x=-6

x=-1

Answer:

x = 6

Step-by-step explanation:

1.5x - 7 + 3x = 20

Combine 1.5x and 3x to get 4.5x.

4.5x - 7 = 20

Add 7 to both sides.

4.5x = 20 + 7

Add 20 and 7 to get 27.

4.5x = 27

Divide both sides by 4.5.

x = [tex]\frac{27}{4.5}[/tex]

Expand [tex]\frac{27}{4.5}[/tex] by multiplying both numerator and the denominator by 10.

x = [tex]\frac{270}{45}[/tex]

Divide 270 by 45 to get 6.

x = 6

Answer:

c = 2

Step-by-step explanation:

Isolate the variable, c. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& roots)

Multiplications

Divisions

Additions

Subtractions

~

First, subtract 6 from both sides of the equation:

9c + 6 (-6) = 24 (-6)

9c = 24 - 6

9c = 18

Next, divide 9 from both sides of the equation:

(9c)/9 = (18)/9

c = 18/9

c = 2

c = 2 is your answer.

33.3

Step-by-step explanation:

First, let's figure out how much more Juan needs to buy a bike: 500-200=300. He earns 9/hr of work. We can now use this information to find the inequality: 300/9=33.3

So Juan needs to work 33.3 hours at least to earn enough money. So therefore he has to work 33.3 hours to earn $300.

Answer: You can't solve for y or x, but you can graph it.

Answer:

£120

Step-by-step explanation:

If the phone has been discounted by 35%, then it is now 65% of the original price (as 100 - 35 = 65).

Divide the discounted price by 65 to find the amount per 1%, then multiply by 100 to get the original price.

(78 ÷ 65) x 100 = £120

Answer:

It was about $222.86

Step-by-step explanation:

1.) First cross multiply [tex]\frac{78}{x}[/tex] x [tex]\frac{35}{100}[/tex]  (new price over original price) x (percent over 100)

2.) 78 x 100 is 7800 and 35 x (x) is just 35x

3.) 35x=7800; So divide by 35 on both sides

4.) You get X= 222.857143 so about $222.86 was the original price

The number of pages read by Laura each day if The book had 85 pages, the same amount every day, and completed the book in just 10 days, is 8.5.

When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.

For instance, 4 2 = 2. As a multiplication fact, this can be expressed as 2 + 2 = 4.

Given:

The book had 85 pages, the same amount every day, and completed the book in just 10 days,

Calculate the number of pages read each day as shown below,

The number of pages read each day = total number of pages / total number of days

The number of pages read each day =85 / 10

The number of pages read each day = 8.5

Thus, The number of pages read each day is 8.5 pages per day.

42.7 in^3 of the interior space is occupied by blue water

Step-by-step explanation:

1.  Find the volume of the ball.

2. Take 85% of this volume.

Volume of a sphere:  V = (4/3)(pi)(radius)^3

Here this volume is V = (4/3)(3.14)(125 in^3), or 50.24 in^3

85% of this volume is 0.85(50.24 in^3) = 42.7 in^3

42.7 in^3 of the interior space is occupied by blue water.
