Given:

Discount = 40%

Sales tax = 7%

To find:

The total cost of levi jeans with an original price of x.

Solution:

Let x be the original price of the jeans. Then the price after 40% discount is

$Price=x-40\%\text{ of }x$

$Price=x-\dfrac{40}{100}x$

$Price=x-0.4x$

$Price=0.6x$

The price after 7% of sales tax.

$Price=0.6x+7\%\text{ of }0.6x$

$Price=0.6x+\dfrac{7}{100}\times 0.6x$

$Price=0.6x+0.042x$

$Price=0.642x$

Therefore, the total cost of the levi jeans with an original price of x is represented by the expression 0.642x.

Joyce has a cone shaped planter hanging on her back porch. If the planter has a radius 6.8 inches and a height of 12.2 inches, w

andriy [413]

Answer:

The total amount of soils that planter will hold to it is 590.45 inches³

Step-by-step explanation:

Given as :

The radius of the cone shape planter = r = 6.8 inches

The height of the cone shape planter = h = 12.2 inches

Let The total amount of soils that will hold to it = x cubic inches

Now, According to question

The total amount of soils that planter will hold to it = The volume of the cone

∵ The volume of cone = v = $\dfrac{1}{3} \pi$ r² h

where r is the radius

And h is the height

So, The total amount of soils that planter will hold to it = $\dfrac{1}{3} \pi$ r² h

or, x = $\dfrac{1}{3}$ × $\pi$ × r² × h

or, x = $\dfrac{1}{3}$ × 3.14 × (6.8)² inches × 12.2 inches

or, x = $\dfrac{1}{3}$ × 3.14 × 564.128 inches³

or, x = $\dfrac{1}{3}$ × 1771.361 inches³

or, x = $\dfrac{1771.361}{3}$ inches³

∴ x = 590.45 inches³

So, The total amount of soils that planter will hold to it = x = 590.45 inches³

Hence, The total amount of soils that planter will hold to it is 590.45 inches³ . Answer

How many solutions does this problem have? | x - 7 | + 3 = - 15

mixer [17]

There are no solutions. By definition of absolute value, $|x-7|\ge0$ , so $|x-7|+3\ge3$ . The left side will always be positive, and a positive number cannot also be negative.

What is the solution to the equation fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n?

photoshop1234 [79]

Answer:

value of n = 2

Step-by-step explanation:

$\frac{4}{5n}-\frac{1}{5}=\frac{2}{5n}$

We need to solve the above equation.

Find Least Common multiplier from 5n, 5 = 5n

Multiply both sides of the equation by 5n

$\frac{4}{5n}*5n-\frac{1}{5}*5n=\frac{2}{5n}*5n\\Solving:\\4 -n = 2\\$

Now finding the value of n.

Adding -4 on both sides

$4 -n-4 = 2-4\\-n= -2$

Multiplying both sides by -1

n = 2

The value of n is 2.

We can verify by putting value of n in the given question.

$\frac{4}{5n}-\frac{1}{5}=\frac{2}{5n}\\n=2\\\frac{4}{5*2}-\frac{1}{5}=\frac{2}{5*2}\\\frac{4}{10}-\frac{1}{5}=\frac{2}{10}\\\frac{2}{5}-\frac{1}{5}=\frac{1}{5}\\\frac{2-1}{5}=\frac{1}{5}\\\frac{1}{5}=\frac{1}{5}$

So, value of n = 2
