Answer:

12.67 minutes

Step-by-step explanation:

Time taken is given by distance divided by speed

Given distance of 228, 000, 000 km and speed of light as 300, 000 km/s then time will be

Time=228, 000, 000/300, 000=760 seconds

Conversion

60 seconds make up 1 minute

760 seconds will be 760/60

Time=760/60=12.666666666666

Rounded off, this is 12.67 minutes

The value of angle C in the triangle is 50°.

<h3>How to calculate the triangle?</h3>

From the information given, the angle A = 60° while B is given as 70° and we are told to calculate the value of C.

It should be noted that the sum of angles on a triangle is 180°. Therefore, the value of C will be:

= 180° - (60° + 70°)

= 180° - 130°

= 50°

Problem 6
Leno4ka [110]

Answer:

8 rabbits

22 chickens

Step-by-step explanation:

c = chickens

r = rabbits

heads - c + r = 30

legs - 2c + 4r = 76

We can now use these two equations to create one by isolating the variable (c) in the first equation.

c = 30 - r

2c + 4r = 76

2(30 - r) + 4r = 76

60 - 2r + 4r = 76

2r = 16

r = 8

Now we know that there are 8 rabbits, which means that there has to be 22 chickens in order to have 30 heads.
