The lengths of the sides of a triangle are 8, 15, and 17. if the longest side of a similar triangle is 51, what is the length of

Vlad1618 [11]

If the longest side on the similar triangle is 51 and the longest side of the first triangle is 17, then you divide 51 and 17.

51 / 17 = 3

So the similar triangle is 3 times as big.
To find the shortest side of the similar triangle, you multiply 8 and 3.

8 * 3 = 24

The length of the shortest side of the similar triangle is 24.

Hope this helps!

Which equation represents a parabola that opens upward, has a minimum at x = 3, and has a line of symmetry at x = 3?

Licemer1 [7]

Answer:

A. y = x^2 -6x + 13

Step-by-step explanation:

The parabola that opens up and has line of symmetry x=3 and a minimum at x=3 is

$y=x^2-6x+13$

The reason is that, we can write this function in the vertex form to get;

$y=x^2-6x+(-3)^2+13-(-3)^2$

$y=(x-3)^2+13-9$

$y=(x-3)^2+4$

Hence the line of symmetry is x=3 and the vertex is (3,4)

A) write an equation <br> B) x= <br> Picture is above

Monica [59]

Answer: Answer is in the steps

Step-by-step explanation:

The interior angles of a triangle add up to one 180 degrees so they all have to add up to 180 degrees.

A) (x+10)° + 50° + (x+20)° = 180°

B) Now solve for x using the equation

x+10 + 50 +x+20= 180

2x + 80 = 180

-80 -80

2x = 100

x = 50

Write the decimal as a fraction or a mixed number in simplest form

natka813 [3]

-0.258 is a decimal number in which 2 is at the tenth place, 5 is at the hundredth place and 8 is at the thousandth place.

Therefore, the number in the fraction form is - $-\frac{258}{1000}$

The fraction in the simplest form is - $-\frac{129}{500}$

-0.312 is a decimal number and its fraction form is - $-\frac{312}{1000}$

The fraction in the simplest form is $-\frac{78}{250} =-\frac{39}{125}$

-2.32 is a decimal number and its fraction in the simplest form is

$-2\frac{32}{100} =-2\frac{8}{25}$

-1.64 is a decimal number and its mixed number in the simplest form is $-1\frac{64}{100} =-1\frac{16}{25}$

6.012 is a decimal number and the number in mixed number form is $6\frac{12}{1000}=6\frac{3}{250}$

-12.405 is a decimal number and the number in mixed number form is

$-12\frac{405}{1000}=-12\frac{81}{200}$
