change 6 out of 100 to a percentage​

Answers

Answer:

6%

Step-by-step explanation:

[tex]\frac{6}{100}[/tex]

For fractions with 100 as the denominator, it will always have the numerator as its percent value. This is because percentages are essentially comparing a number to 100, which is what [tex]\frac{6}{100}[/tex] is doing. Therefore, [tex]\frac{6}{100}[/tex] as a percentage would be 6%.

Answers

Complete Question:

Jocelyn said that the triangle below is not a right triangle. Her work is shown below. Explain what she did wrong, and show Jocelyn the correct solution.

We need to check if 27² + 45² = 36² is a true statement. The left side of the equation is equal to 2,754. The right side of the equation is equal to 1,296. That means 272 + 452 = 362 is not true, and the triangle shown is not a right triangle

Answer/Step-by-step explanation:

Jocelyn used a wrong equation and statement.

Here's what she should have stated and done.

Using the converse of Pythagorean Theorem, which says that a triangle with sides a, b, and c is a right triangle if it satisfy the statement: a² + b² = c².

Where, c is the hypotenuse which is the longest leg. While a and b are the side lengths of the other two legs.

Therefore, in this case,

c = 45

b = 27

a = 36

Thus, what we need to check to be true would be:

36² + 27² = 45² (this is where Jocelyn made a mistake. Jocelyn wrote 27² + 45² = 36² rather)

Let's check if it's true.

2,025 = 2,025 (this is true)

Therefore, the triangle is a right triangle.

Connor and Angie helped take attendance during their school's practice

actual attendance was 470. What is the percent error? (ROUND TO THE
NEAREST TENTH.) *
0.019
1.2%
1.9%
12%

Answers

Answer: 1.9%

Step-by-step explanation:

The percent error formula is [tex]\frac{accepted-experimental}{accepted}[/tex] so input our values also keep in mind when we do percent error we use absolute error which means no negative percentages so 470-479/470= -9/470 or 9/470

as a decimal 9/470 is 0.019 or 1.9% so the answer is 1.9%
