You are really excited to have found a Puch Maxi Moped from the mid Eighties, and the spring weather is making you want to get out and ride it around. It doesn't run on straight gasoline, you have to mix the oil and gas together in a specific ratio of 2.4 fl. oz. of oil for every gallon of gasoline.
You have 3.75 gallon of gas. How much oil should you add?

Answers

Answer:

Step-by-step explanation:

You should add 9 fl. oz. of oil to your 3.75 gallons of gas.

Puch Maxi Moped from the mid-Eighties now since this moped doesn't run on straight gasoline, you need to create a special fuel mixture. This involves combining oil and gas in a specific ratio. The magic ratio here is 2.4 fl. oz. (fluid ounces) of oil for every gallon of gasoline.

You mentioned you've got 3.75 gallons of gas. To figure out how much oil you need, we can use some math. First, let's find out how much oil is required for one gallon of gas:

2.4 fl. oz. of oil/gallon x 1 gallon = 2.4 fl. oz. of oil.

So, for 3.75 gallons of gas, you'll need:

2.4 fl. oz. of oil/gallon x 3.75 gallons = 9 fl. oz. of oil.

You should add 9 fluid ounces of oil to your 3.75 gallons of gas to create the proper fuel mixture for your Puch Maxi Moped.

The constant term is 2 and the variable terms are '9gh' and 'g' in the given polynomial.

What is a polynomial?

A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.

The polynomial is given below.

⇒ 2gh + 2 + g

In the above polynomial, the letter 'g' and 'h' are variables.

The constant term is that term in which no variable is there. Then the constant term is 2.

And the variable terms are '9gh' and 'g'.

Step-by-step explanation:

[tex]\frac{7}{12} -\frac{4}{15} \\=\frac{35}{60} -\frac{16}{60} \\=\frac{19}{60}[/tex]

Answer:

[tex]\frac{19}{60}[/tex] or 0.3166667

Step-by-step explanation:

let's first make the denominators the same so it can be easier to subtract:

[tex]\frac{7}{12}[/tex] × [tex]\frac{15}{15}[/tex] = [tex]\frac{105}{180}[/tex]  and [tex]\frac{4}{15}[/tex] × [tex]\frac{12}{12}[/tex] = [tex]\frac{48}{180}[/tex]

so now we do:

[tex]\frac{105}{180}[/tex] - [tex]\frac{48}{180}[/tex]  =  [tex]\frac{57}{180}[/tex]  = [tex]\frac{19}{60}[/tex]

What is the measure of Zx?
Angles are not necessarily drawn to scale.
B

109°
D

E
А

Answers

Answer:

a straight line has an angle of 180

therefore 180-109=71

71÷2 = 35.5

x is 35.5 degrees

The measure of x is 29 degree.

What is Parallel line?Straight lines that are always the same distance apart from one another are called parallel lines.No matter how far apart they are from one another, parallel lines can never intersect.

As, Parallel line have property

Any two lines are considered to be parallel if the angles formed by them are equal.If the Opposite interior angles formed by two lines are equal, they are said to be parallel.If the Opposite exterior angles formed by two lines are equal, they are said to be parallel.If the Successive interior angles on the same side of the transversal are additional, two lines are said to be parallel.

As, <CBA = <BAD (Alternate Interior Angle)

So, <BAD = 42

Now, <BAD + <BAC + <CAE = 180 (Linear Pair)

42 + 109 + x = 180

151 +x = 180

x = 180- 151

x = 29
