A literal equation has only one variable.
True
False

Answers

Answer 1
Answer: <b>The answer is False.</b>

<b>The reason is that, the letters or variables in a literal equation are like parameters that can be any real number.</b>

A literal equation has two or more variables or letters, that are used to represent real values.

An example is the perimeter of a square, which is given by the formula,

P=4l
Here, the P represents perimeter of the square and l represents the length of the square.

Since the length of a square can assume any positive value,the above literal equation has <b>infinitely many solutions</b>.

For instance, if

l=1, P=4*1=4

l=2, P=4*2=8

and so on and so forth.

Other examples of literal equations include:

The perimeter of a rectangle, which is given by the formula:

P=2w + 2l

The formula for finding the perimeter of a circle:

C = 2 \pi \: r

The set of values that satisfy the above formulas are infinitely many.

4% is not equivalent to 40%
0.4 is equivalent to 40%.  Just move the decimal two places to the right.
2/5 is equivalent to 0.4,  which in turn is equivalent to 40%.  2 divided by 5=0.4

How do you convert units within a measurement system☺️

Answers

You have to know how the value of one unitcorresponds to the value of the other unit. For example you have to knowthat there are 100 cm in 1 m or 1000 m in 1 km. It's easy in metricmeasurement system because it's all about multiplying/dividing by 10 orits multiplications. But in American/English system you just have tolearn the values.

For example:

1 km = 1000 m = 10000 dm = 100000 cm = 1000000 mm

But:

1 mile = 1760 yards = 5280 feet = 63360 inches

(4 pts) Henry walks out of his hall and proceeds to walk 200 feet due north. He then turns left (west) and walks 190 more feet. Finally, he turns 45∘ left and walks 260 feet. How many feet is Henry from his starting point

Answers

Answer:

Henry is approximately 276 feet from his starting point.

Step-by-step explanation:

To find how many feet Henry is from his starting point, you can use the Pythagorean theorem because he walked in both the north and west directions, creating a right triangle. Here's the calculation:

1. The distance he walked north is 200 feet.

2. The distance he walked west is 190 feet.

3. The 45-degree angle forms a right triangle.

Now, use the Pythagorean theorem:

a² + b² = c²

Where:

a = 200 feet (north)

b = 190 feet (west)

a² + b² = c²

(200)² + (190)² = c²

40000 + 36100 = c²

76100 = c²

Now, find the square root of 76100:

c = √76100 ≈ 276 feet

So, Henry is approximately 276 feet from his starting point.
