4/5 os the fourth multiple of what unit fraction?

2 answers:

6 0

So, the unit fraction would be 1/5. Keep going from there to 2/5, 3/5, 4/5. So 4/5 was the fourth multiple, However, the answer would have to be a unit fraction and a factor of 4/5, so it has to be 1/5. Equation: 1/5 x 4 = 4/5

I do believe it is the 4th multiple of 1/5 because the unit fraction is 1/5, so if you multiple 1/5 times 4, i believe you get 4/5.

Find all the missing elements

Roman55 [17]

Answer:

$b = 5.5$

$c = 11.2$

Step-by-step explanation:

Given:

A = 96°

B = 25°

C = 59°

a = 13

Required:

b and c

SOLUTION:

Use Sine Rule to find the measure of a and b, respectively.

✍️Thus, to find b, use,

$\frac{a}{sin(A)} = \frac{b}{sin(B)}$

Plug in the values

$\frac{13}{sin(96)} = \frac{b}{sin(25)}$

Multiply both sides by sin(25)

$\frac{13}{sin(96)} \times sin(25) = \frac{b}{sin(25)} \times sin(25)$

$\frac{13 \times sin(25)}{sin(96)} = b$

$b = 5.5$ (nearest tenth)

✍️To find c, use,

$\frac{a}{sin(A)} = \frac{c}{sin(C)}$

Plug in the values

$\frac{13}{sin(96)} = \frac{c}{sin(59)}$

Multiply both sides by sin(59)

$\frac{13}{sin(96)} \times sin(59) = \frac{c}{sin(25)} \times sin(59)$

$\frac{13 \times sin(59)}{sin(96)} = c$

$c = 11.2$ (nearest tenth)
