Answer: £268.20

Step-by-step explanation:

1/3 of 495 is 165.

124 x .50 = 62.

165 + 124 = 289

495 - 289 = 206

206 x .20 = 41.20

165 + 62 + 41.20 = 268.20

Propane (C3H8), a fuel that is used in camp stoves, produces carbon dioxide (CO2) and water vapor (H2O) on combustion as follows

Vilka [71]

Answer:

23.30 liters of propane are required at STP to produce 75 g of water from this reaction.

Step-by-step explanation:

$C_3H_8+5O_2\rightarrow 3CO_2+4H_2O$

Water produced = 75 g

Moles of water = $\frac{75 g}{18.02 g/mol}=4.1620 mole$

1 mole of propane gives 4 moles of water.

Then, 4.1620 moles of water will be obtained form:

$\frac{1}{4}\times 4.1620=1.0405 mole$ of propane

At STP ,1 mole of gas occupies = 22.4 L

Then, 1.0405 mole will occupy:

$1.0405\times 22.4 L=23.30 L$

23.30 liters of propane are required at STP to produce 75 g of water from this reaction.

Write an algebraic expression to represent the area of the triangle (Area = 1/2 ×base ×height) given that the length is 6 inches

shusha [124]

The expression for area of triangle is 1/2x² + 3x.

<h3>What is Algebra?</h3>

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

Area = 1/2 × base × height

and, length is 6 inches greater than the height.

let the height of the triangle is x

length of triangle = x + 6

So, The Area of triangle

= 1/2 x base x height

= 1/2(x)(x+ 6)

= 1/2x² + 3x

Hence, the expression for area of triangle is 1/2x² + 3x.

What is 175-18×9÷6 Order of operations

Neporo4naja [7]

According to PEMDAS,
*Parenthesis
*Exponents
*Multiplication
*Division
*Addition
*Subtraction

You do them left to right.
18 * 9 = 162.
162 / 6 = 27
175 - 27 = 148

Hope this helps! ☺♥
