Here is the answer to the given question above. Given that there are a total of 18 students and 5/9 of the students have pets, let us divide 18 by 9 to see how many students have pets. So the answer would be 2. Since it is 5 out of 9, we multiply 2 by 5 and we get 10. Therefore, the answer is 10 students. Hope this answer helps.

Which set of numbers could represent the lengths of the sides of a right triangle?
Vera_Pavlovna [14]

Answer:

8, 15, 17

Step-by-step explanation:

The 2nd option. You know this by using this math formula: a^2 + b^2 = c^2. That is the formula to find a right triangle. So if you square 8 and 15 you get 64 and 225, and if you add them together you get 289, which is 17^2. Hope this helps! :)

Elina [12.6K]

Answer:

35 dogs

Step-by-step explanation:

x ---> the number of dogs

y ---> the number of cats

The last week of January we have 20 cats and the ratio is the same

so

\frac{x}{y}=\frac{49}{28} ----> equation A

y=20 ---> equation B

substitute equation B in equation A

\frac{x}{20}=\frac{49}{28}

solve for x

x=\frac{49}{28}(20)=35 dogs

A right rectangular prism's edge lengths are 12 inches, 2 1/6 inches, and 4 inches. How many unit cubes with edge lengths of 2/3
zhenek [66]

Answer:

<h2>324 cubes</h2>

Step-by-step explanation:

We calculate how many cubes will fit along each edge:

12 in : 2/3 in = 12 · 3/2 = 18 cubes

2 1/6 in : 2/3 in = 13/6 · 3/2 = 39/12 = 13/4 = 3 1/4 → 3 cubes

4 in : 2/3 in = 4 · 3/2 = 6 cubes

(18)(3)(6) = 324
