Answer:

Mr. Smiths class has 12 students and Mrs. Brown's class has 10 students.

Step-by-step explanation:

if 1/3 of the class is absent and that amount is four you would multiply 4 by 3 and get 12. If 2/5 of the class are missing and there 4 students first you would divide 4 by 2 and get 2, then you would take the 2 and multiply it by 5 and get 10.

Homework - Pure Year 1 - Chapter 11B
ycow [4]

Answer:

|F net| = 20.22 N

θ ≈ 19.8°

Step-by-step explanation:

F net = 15N i + 8cos(60°)N i + 8sin(60°)N j

= 15N i + 8×½N i + 8×√3/2N j

= 15N i + 4N i + 4√3N j

= 19N i + 4√3N j

|F net| = √(19²+(4√3)²) = √(361+48) = √409 ≈ 20.22N

tan(θ) = 4√3 ÷ 19 ≈ 0.36 → θ ≈ arctan(0.36) = 19.8°

57°
noname [10]

Answer:

c = 29

Step-by-step explanation:

Law of sines is given as: \frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)}

B = 180 - (57 + 44) = 79°

b = 41

C = 44°

c = ?

Thus:

\frac{b}{sin(B)} = \frac{c}{sin(C)}

Substitute

\frac{41}{sin(79)} = \frac{c}{sin(44)}

Multiply both sides by sin 44

\frac{41}{sin(79)}*sin(44) = \frac{c}{sin(44)}*sin(44)

\frac{41*sin(44)}{sin(79)}*sin(44) = c

c = 29.0140633 ≈ 29
