What is the value of x?

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

sin = opposite side / hypoteneuse side

opposite side = x

hypoteneuse side = 8

thus; sin 30° = x/8

x = sin 30°×8

= 0.5 × 8

= 4

Answer 2

Answer: By Sine Rule,

x/sin30° = 8/sin90°

x/0.5 = 8/1

So x = 4.

A farmer in china discovers a mammal hide that contains 25% of its original amount of c-14

Answers

Plato answer is 13863

You have left a LOT out of your question. However I'll attempt to post an answer.

The half-life of carbon 14 is 5,700 years.

If there is 25% of the original carbon 14 remaining that means the time it has undergone has been 2 half lives.

2 half-lives of carbon14 = 2 * 5,700 = 11,400 years.

Charlie measured the circle-shaped part of a sun his sister drew on the chalkboard. The circumference of the circle is 75.36 cm. What is the diameter? (Use 3.14 for .)

Answers

Answer:

The diameter of circle is 24 cm.

Step-by-step explanation:

We are given the following in the question:

Circumference of circle = 75.36 cm

We have to find the diameter of the circle.

Circumference of circle =

$C =2\pi r$

where r is the radius of the circle.

Putting values, we get,

$75.36 = 2* 3.14* r\n\nr = (75.36)/(2* 3.14)\n\nr=12$

Diameter of circle =

$d=2r\nd=2* 12=24\text{ cm}$

Thus, the diameter of circle is 24 cm.
