X=35 and y= 130.
similar triangles have at least 2 congruent angles.
ABC = 130, 35 and 15
DEF = 130, 35 and 15
so B) the triangles are similar because y=130 and there are 3 pairs of congruent angles.

The relationship between the length and weight of certain sea turtles can be approximated by the equation L = 0,55 W,
Liono4ka [1.6K]

Answer:

4.55 pounds

Step-by-step explanation:

From the above question , we are told that:

The relationship between the length and weight of certain sea turtles can be approximated by the equation

L = 0.55 W,

where

L is the length in feet

W is the weight in pounds. If a sea turtle is 2.5 feet long, which is closest to its weight?

L = 2.5 feet

Hence,

2.5 = 0.55W

W = 2.5/0.55

W = 4.5454545455 pounds

Approximately, weight of the sea turtle in pounds = 4.55 pounds

Once Farid spends 15 minutes on a single level in his favorite video game, he loses a life. He has already spent 10 minutes on t
Zolol [24]

Answer:

0.6666 or \frac{1}{3}

Step-by-step explanation:

Since this is a ratio problem we can simply use the rule of three to solve it. We need to multiply the diagonal values and divide by the remaining value to get the variable which in this case is x (how much life he has already lost)

15 minutes   <=======>   1 life

10 minutes   <=======>   x

(10 * 1) / 15 = x

10 / 15 = x

0.6666 or \frac{1}{3}  = x

Finally, we can see that Farid has lost 0.6666 or \frac{1}{3} in those 10 minutes

the length of a chord of a circle is 24 cm long and is 5 cm away from the center of the circle what is the radius of the circle​
iogann1982 [59]

Answer:A chord with length 24 cm at 5 cm from the center gives a radius of 13 cm, using a half-length of 12 cm and the distance of 5 cm in Pythagoras’s theorem to find the radius.

Using the same radius and Pythagoras's theorem again, a chord 10 cm from the circle with radius 13 cm has a half-length of sqrt(69), or a full length of double that, so 2*sqrt(69).

A polynomial function P(x) with rational coefficients has the roots sqrt 2 and - sqrt 13. Find two additional roots.
bixtya [17]

Answer:

-\sqrt{2} and \sqrt{13}

Step-by-step explanation:

Given a polynomial with rational coefficients, its irrational and complex roots would occur in conjugate pairs.

For example, if the roots of a polynomial are 2 + \sqrt{3}, 3 and 4 - 3i, then 2 - \sqrt{3}, and 4 + 3i are also roots of the polynomial.

Therefore, since the given polynomial has rational coefficients and some of its roots are , \sqrt{2} and  - \sqrt{13}, then -\sqrt{2} and \sqrt{13} are also roots of the polynomial.
