I need help with problem 6) A. Please help.
vampirchik [111]

Answer:

  • 60
  • 18

Step-by-step explanation:

The ratios are all 3 father steps to 5 son steps. Then ...

  son-steps = 5/3·father steps

  son-steps = 5/3·36 = 60

and

  father-steps = 3/5·son-steps

  father-steps = 3/5·30 = 18

___

As a <em>check</em>, you can realize that the numbers in the first blank, 36:60, are double those in the second blank, 18:30. The first of these, 36:60, is 3 times the row underneath it, 12:20.

please help me! What is the approximate value of y? Round to the nearest tenth. A.) 3.1 B.) 3.9 C.) 4.6 D.) 5.4
cluponka [151]

Answer:

Option (C). 4.6 cm

Step-by-step explanation:

In the figure attached,

A right triangle has been given with hypotenuse = 6 cm, leg 1 = x cm, leg 2 = y cm and one angle = 50°

By applying Sine rule in this triangle,

Sin(50)° = \frac{\text{Opposite side}}{\text{Hypotenuse}}=\frac{\text{Leg 1}}{\text{Hypotenuse}}

Sin(50)° = \frac{x}{6}

x = 6(Sin50°)

x = 4.59

x ≈ 4.6 cm

Therefore, Option (C) will be the answer.
