Answer:

There are 35 boys in the class.

Step-by-step explanation:

This question can be solved as a rule of three.

In science class, the girl to boy ratio is 3 to 7.

This means that for each 10 students, 7 of them are boys and 3 are girls.

So if for 10 students, 7 of them are boys, how many are boys for 50?

7 boys - 10 students

x boys - 50 students

10x = 7*50

10x = 350

x = 35

There are 35 boys in the class.

Subtract 37/55-32/55
lana66690 [7]
The answer would be 5/55 because if you subtract 32 from 37 you would end up with 5 and because the denominator was the same you keep the denominator the same.

Determine e, k, and identify the type of conic for r= 12/ 7- cos theta
nlexa [21]

Answer:

The answer is (d) ⇒ e = 1/7 , k = 12 , conic ellipse

Step-by-step explanation:

∵ r = ek/(1 ± ecosФ)

∵ r = 12/(7 - cosФ) ⇒ ÷ 7 up and down

∴ r = 12/7 ÷ 1 - 1/7 (cosФ)

∴ e = 1/7

∵ 12/7 = ke ⇒ 12/7 = k(1/7)

∴ k = 12

∵ 0 < e < 1

∴ The conic is ellipse
