If 10% of a number is 36 and 55% of the same number is 198, find 45% of that number.

9514 1404 393

  162

Step-by-step explanation:

There are many ways to work this. Perhaps the simplest is to recognize that 45% of the number is the difference between 55% of it and 10% of it.

  0.55n -0.10n = 0.45n

  198 -36 = 0.45n = 162

45% of the number is 162.

If you like, you can find the number as ...

  0.10n = 36

  n = 36/0.10 = 360

Then you can verify (if you like), that 55% of it is 198:

  0.55(360) = 198 . . . . true

Finally, you can figure 45% of it:

  0.45(360) = 162

__

Using proportions, you can determine the number to be ...

  36/0.10 = n/0.45

  n = 0.45(36/0.10) = 4.5(36) = 162

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
