The height of a triangle is 9, the length is 5, what is the third side?

1 answer:

5 0

Use the Pythagorean Theorem to solve for the third side. The third side must be the hypotenuse since the height (vertical leg) is 9, and the length (horizontal leg) is 5.

a² + b² = c², where a and b are the legs and c is the hypotenuse. Plug in 5 and 9 for a and b; solve for c.

5² + 9² = c² ⇒ 25 + 81 = c²

106 = c²

Square root both sides.

c = 10.3

Third side: 10.3

Based on the scatterplot, which equation BEST represents the relationship between velocity and time?

lutik1710 [3]

The line of best-fit that represents the relationship between velocity and time is:

v = 2.19t + 6.7.

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (t,v) are given as follows:

(0, 6.1), (2.1, 12.2), (5.3, 17.4), (8.2, 26.4), (10, 28.1), (12.1, 32.8).

Hence, inserting these points into a calculator, the equation is given by:

v = 2.19t + 6.7.

Sean paints 8/15 of a fence in 1 hour. He paints 3/10 of the fence less in the second hour. What fraction of the fence did he pa

a_sh-v [17]

Answer: $\frac{3}{10}$

Step-by-step explanation:

Given

Sean paints $\frac{8}{15}$ of a fence in 1 hour

Sean paints $\frac{3}{10}$ part less in the second hour

So, fraction he paints in the second hour = $\frac{8}{15}-\frac{3}{10}=\frac{16-9}{30}=\frac{7}{30}$

Paint in 2 hours = $\frac{8}{15}+\frac{7}{30}=\frac{16-7}{30}=\frac{9}{30}$

= $\frac{3}{10}$

No, he did not finish his job
