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.

Answer:

Part 1) The unit rate is 16\frac{dollars}{ounce}

Part 2) The unit rate is \frac{1}{4}\frac{dollars}{ounce}

Part 3) The unit rate is \frac{1}{4}\frac{dollars}{ounce}

Part 4) The unit rate is 4\frac{dollars}{ounce}

see the attached figure

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

m=\frac{d2-d1}{n2-n1}

where

d ----> number of dollars (dependent variable or output value)

n ---> number of ounces (independent variable or input value)

Remember that the slope of the linear equation is the same that the unit rate

<u><em>Verify each case</em></u>

1) we have

d=16n

This is a proportional relationship between the variables d and n

The slope is

m=16\frac{dollars}{ounce}

therefore

The unit rate is 16\frac{dollars}{ounce}

2) we have

<em>First table</em>

take two points from the table

(4,1) and (16,4)

substitute in the formula of slope

m=\frac{d2-d1}{n2-n1}

m=\frac{4-1}{16-4}

m=\frac{3}{12}\frac{dollars}{ounce}

simplify

m=\frac{1}{4}\frac{dollars}{ounce}

therefore

The unit rate is \frac{1}{4}\frac{dollars}{ounce}

3) we have

n=4d

This is a proportional relationship between the variables d and n

isolate the variable d

d=\frac{1}{4}n

The slope is

m=\frac{1}{4}\frac{dollars}{ounce}

therefore

The unit rate is \frac{1}{4}\frac{dollars}{ounce}

4) we have

<em>Second table</em>

take two points from the table

(1,4) and (2,8)

substitute in the formula of slope

m=\frac{d2-d1}{n2-n1}

m=\frac{8-4}{2-1}

m=4\frac{dollars}{ounce}

therefore

The unit rate is 4\frac{dollars}{ounce}
