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

Mathematics

pentagon [3]3 years ago

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

Answer:

Dilate circle A by a scale factor of 4.

Step-by-step explanation:

Dilating circle A by 4 would be the same as multiplying its radius of 6 by 4, which would make it 24.

The radius of circle B is 24.

Rotating it wouldn't change anything (it's a circle), and I don't think reflecting and translating show circle similarity

-1/2(-3y+10) i need help combining like terms to create a equivelent expression
Vaselesa [24]

Answer:

1.5y - 5

Step-by-step explanation:

I used the distributive approach and distributed -1/2 to the -3y and 10.

(If you try this and it's incorrect, you may just need to distribute -1/2 to the 10, creating -3y - 5.)

Answer:

The answer to your questions are:

15.- 45 mg

16.- 25 kg

17.- 185 pounds

18.- 6 mg

Step-by-step explanation:

                                            D = (a M)  / (a + 12)

15.-

a = 4 years

M = 180

                                      D = (4 x 180) / (4 + 12)  = 720 / 16

                                      D = 45 mg

16.-                                1 pound --------------- 0.4535 kg

                                   55 pounds ------------  x

                                  x = 55 x 0.4535 / 1  

                                 x = 24.94 ≈25 kg

17.-                                1 pound --------------- 0.4535 kg

                                    x             ---------------   84.09 kg

                           x = 84.09x 1 /0.4535

                          x = 185.42 pounds  

18.-  M = 18 mg        what is 1/3 of the adult dose?

                          M = 18/3 = 6 mg
