Robert mixed 1 1 3 liters of blue paint with 1 2 3 liters of red paint to make 3 liters of purple paint. To make a new batch of purple paint he used 2 liters of red paint. Using the same ratio, Robert should use Response area liters of blue paint . brainly

Answers

Answer: Hence, [tex]1\dfrac35[/tex] liters of blue paint have been used.

Step-by-step explanation:

Given: Robert mixed [tex]1\dfrac13[/tex] liters of blue paint with [tex]1\dfrac23[/tex] liters of red paint to make 3 liters of purple paint.

[tex]1\dfrac13=\dfrac{4}{3}\\\\ 1\dfrac23=\dfrac{5}{3}[/tex]

Ratio of blue paint to red paint = [tex]\dfrac{\dfrac{4}{3}}{\dfrac53}=\dfrac{4}{5}=4:5[/tex]

let x be the quantity of blue paint used with 2 liters of red paint..

Then

[tex]x:2=4:5\\\\\Rightarrow\ x=\dfrac{4\times2}{5}\\\\\Rightarrow\ x=\dfrac85=1\dfrac35[/tex]

Hence, [tex]1\dfrac35[/tex] liters of blue paint have been used.

The amount of blue paint used is  [tex]1\dfrac{3}{5}[/tex] liters and this can be determined by using the arithmetic operations.

Given :

Robert mixed [tex]1\dfrac{1}{3}[/tex] liters of blue paint with [tex]1\dfrac{2}{3}[/tex] liters of red paint to make 3 liters of purple paint.To make a new batch of purple paint he used 2 liters of red paint.

Amount of Blue Paint = 4/3 liters

Amount of Red Paint = 5/3 liters

Now, the ratio of blue paint to red paint is given by:

[tex]=\dfrac{\dfrac{4}{3}}{\dfrac{5}{3}}[/tex]

[tex]=\dfrac{4}{5}[/tex]

Now, assume that the amount of blue paint that is used with 2 liters of red paint is 'a'. Then it is given that using the same ratio, Robert should use response area liters of blue paint, that is:

[tex]\dfrac{a}{2}=\dfrac{4}{5}[/tex]

[tex]a = \dfrac{8}{5}[/tex]

[tex]\rm a = 1\dfrac{3}{5} \; liters[/tex]

Therefore, it will be said that [tex]1\dfrac{3}{5}[/tex] liters of blue paint is used.

A gallery owner purchased a very old painting for 3000 dollars. The painting sold for 325 percent increase in price. What is the retail price of the printing?

Answers

Answer:

$12,750

Step-by-step explanation:

The price at purchase = 3000 dollars

Sale = 325 percent increase in purchase price.

325% = 3.25

3.25x3000 = 9750 dollars

So, at 325 percent increase in price, this painting sold for $9750.

The retail price of this painting =

Price at purchase + price during sale

= 3000 + 9750

= $12,750

Therefore the retail price is equal to $12,750

Use what you've learned about cosecant, secant, and cotangent to solve the following problem. Unless otherwise stated, round your answers to the nearest thousandth. Use cosecant, secant, or cotangent to find the value of x.​

Answers

Hello! :)

[tex]\large\boxed{x \approx 7.064}}[/tex]

In the diagram, we are given the opposite side of ∠A as 8.

We are trying to solve for the adjacent side, so we must use the appropriate trig.

Cotangent uses both the adjacent and opposite sides, so we can use this to find the value of x.

Cot (angle) = Adjacent / Opposite, therefore:

cot (28°) = x / 8

Multiply both sides by 8 to isolate for x:

8 · cos(28°) = x

Evalute cos(28°) using a calculator:

cos(28°) ≈ 0.88295

Multiply by 8 to solve for x:

8 · cos(28°) ≈ 7.064

The absolute value function |x| always returns a non-negative number. It takes any number x and returns x if it's already non-negative, or -x if it is negative in order to make it positive.

[tex]|x|=\begin{cases}x&\text{for }x\ge0\\-x&\text{for }x<0\end{cases}[/tex]

For the equation

-3 + 4 |2x - 5| = 14

rearrange terms to get

|2x - 5| = 17/4

Now,

• if 2x - 5 ≥ 0, then |2x - 5| = 2x - 5. Then

2x - 5 = 17/4

• and if instead 2x - 5 < 0, then |2x - 5| = -(2x - 5), so that

-(2x - 5) = 17/4, or

2x - 5 = -17/4

In the first case,

2x - 5 = 17/4

2x = 17/4 + 5 = 37/4

x = 37/8

In the second case,

2x - 5 = -17/4

2x = -17/4 + 5 = 3/4

x = 3/8
