a right triangle has a hypotenuse with a length of 20. the lengths of the legs are whole numbers. what are the lengths of the le
Y_Kistochka [10]

Answer:

12;16

Step-by-step explanation:

The Pythagorean theorem states that

a^2+b^2=c^2 where a and b are legs of a triangle, and c is the hypotenuse.

This means that we have to find 2 values that once squared, add up to 400. (20^2)

Based on this, we can use the values of 12 and 16 to satisfy this.

12^2+16^2=144*256=400

Therefore, the legs of the triangle are 12 and 16.

Notebooks cost $ 1.20 each. This weekend they will be on sale for $ 0.80. What percentage is the sale
Rainbow [258]

From the information we have, we know that each book costs 1.20 dollars. So we shall say this price is at 100% .

Now we need to form an equation to get the percentage  when the books are sold at 0.80 dollars.

100% = 1.20

       x = 0. 80

Where x is the new percentage when the sale is at 0.80 dollars.

We cross multiply the equation:

1.20 *x = 0.80 * 100

1.2x = 80

x = 80/1.2

x = 66.7%

Round off 66.7 to the nearest tenth we get 67%

The notebooks are sold at 67% (of the original cost).

For the statement​ below, write the claim as a mathematical statement. State the null and alternative hypotheses and identify wh
vfiekz [6]

The question is not complete, so i have attached it.

Answer:

A) Option B: μ ≤ 19,000

B) Option C:

H0: μ ≤ 19,000

Ha: μ > 19,000

C) Option D: The null hypothesis H0: μ ≤ 19,000 is the claim

Step-by-step explanation:

A) From the question, we are told that an amusement park claims that the mean daily attendence at the park is at most 19,000 people.

Now, since it's at most 19000 people, it means that they are either 19000 or less. So the claim is;

μ ≤ 19,000 which is option B

B) Now, the claim is usually the null hypothesis. Thus, the null hypothesis is;

H0: μ ≤ 19,000

While the alternative hypothesis which states the opposite of the claim is;

Ha: μ > 19,000

So, option C is the correct answer

C) The claim is μ ≤ 19,000

Now, this also happens to be the null hypothesis.

Thus, the null hypothesis H0: μ ≤ 19,000 is the claim.

So option D is correct.
