how many seconds did nolan take?

The time taken by Nolan to complete multiplication test is 100 seconds  .

Step-by-step explanation:

Given as :

The time by Kong to complete multiplication test = x = 85 seconds

The time by Kong to complete multiplication test = 15 % less than that of Nolan

Let The time taken by Nolan to complete multiplication test = y seconds

Now, According to question

∵The time by Kong to complete multiplication test = 15 % less than that of Nolan

So, The time by Kong to complete multiplication test =  time taken by Nolan - 15% of  time taken by Nolan

i.e x = y - 15 % of y

Or, x = y × (1 - )

Or, x = y ×

Or, x = y ×

Now, Since x = 85 seconds

So, 85 =  y ×

Or, y =

i.e y = 100

So,The time taken by Nolan to complete multiplication test = y = 100 seconds

Hence,The time taken by Nolan to complete multiplication test is 100 seconds  . Answer

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
