If £1 is equal to 99.72 rupees and the post office only has 500 rupee papers how much can I change out of £450
sweet [91]

£1 = 99.72 rupees -> £450 = 44874 rupees.

As the post office only has 500 rupee papers, once we calculate out the result, we have to round down to the nearest whole number.

The amount of rupee papers we can change out is : 44874 : 500 = 89.748 (papers)
We round down to 89 papers.

Suppose that m∠MKN = 55°. What is m∠MCN?<br> !please no absurd answers!
Elena L [17]

Answer:

angle M and N are right angles

we can draw a line joining M and N  

so we’d have a triangle MNC AND KMN

both MNC AND KMN BECOME ISOSCELES TRIANGLES

so since we have 55 degrees for angle MKN. We have to find the other 2

180-55=125

now divide by 2 to get 62.5 for each of the remaining sides of triangle KMN

now to find the sides of triangle MNC

90-62.5= 27.5

27.5*2= 55

180-55=125=angle C

(sorry, it’s complex)

If 6 teenagers can drink 6 ice cream sodas in 2 minutes. how many ice cream sodas can the same 6 teenagers drink in 2 hours
san4es73 [151]
Not sure if I’m correct, but 360 because I’m 1 minute they can drink 3 ice cream sodas, so multiply 3 by 60, the 60 is supposed to be 60 minutes, once you get that amount that you multiplied (180) add it again (180+180) the total should be your answer.
