Solve for the value of k. (k+8) 400​

Mathematics
1 answer:
pashok25 [27]3 years ago
3 0

Answer:

value of k = 6

Step-by-step explanation:

sum of all angles forming a straight line = 180°

so,

  • 7k + 8 + 90 + 40 = 180
  • 7k + 138 = 180
  • 7k = 180 - 138
  • 7k = 42
  • k = 42/7
  • k = 6

hence the value of k = 6

The width of a kitchen is 4.2 metres.
Zolol [24]

Answer:

11,67

Step-by-step explanation:

In the order to get the answer, we need to get the right measurements. That is turn the cm into m or 60 cm to 0,6 m because 1 cm is 0.01m. How many cupboards in a kitchen that is 4,2 m long? To get the answer just divide 4,2 m with 0,6 m, and that is 11,67 cupboards in a 4,2 m long kitchen.

1. June says that there should be a decimal point in the quotient below after the 4. Is she correct? Use number sense to explain
charle [14.2K]

43.94 / 5.2 = 845 is impossible because it would mean that 845 * 5.2 is equal to 43.94 which would be a non sense.

Even if you multiply 84.5 * 5.2 you will still get a bigger result than 43.94 obviously.

The only way this division would make sense, it is if the result is 8.45 so the decimal point should be before the 4 and not after it so June is not correct.

GOod luck :)
