First convert them to fractions (the answer choices are fractions):

a) 0.333... = 1/3
b) 0.555... = 5/9

Now add a and b:

1/3 (or 3/9 for a common denominator) + 5/9 = 8/9

That fraction is in simplest form, so leave it as it is.

Hope this helps!

What is the volume of the following rectangular prism? 21/2 units 8/3 units

xeze [42]

Answer:

28 units³

Step-by-step explanation:

The volume (V) of the prism is calculated as

V = Al ( A is the area of end face and l is the length )

Here A = $\frac{21}{2}$ and l = $\frac{8}{3}$ , thus

V = $\frac{21}{2}$ × $\frac{8}{3}$ ( cancel 21 and 3 by 3 and 2 and 8 by 2 )

= $\frac{7}{1}$ × $\frac{4}{1}$ = 7 × 4 = 28 units³
