Hannah has some scraps of ribbon measuring 3.52 meters, 17.3 meters and 27.009 meters. does she have enough to do a project requiring 50 meters of ribbon? if yes, how much ribbon will she have left? if no, how much more ribbon does she need?

No, 2.171m.

Step-by-step explanation:

Add all of measurements. 3.52+17.3+27.009=47.829

Compare 2 numbers.

47.829<50

So she needs more ribbon,because the length she has is less the requirement, 50m.

Find the difference(the length she needs).

50-47.829=2.171

the true ones are a b and d

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
