Total of 49 1/4 + 3 3/8

Ede4ka [16]

49*4=196+1=197/4
8*3=24+3=27/8 

then make the denominator the same
multiply 197*2 and 4*2 = 394/8 
then 394/8 +27/8 =421/8 
u can either leave it here or in decimal form which would be 52.625 or in mixed numbers-52 5/8

Consider functions f and g.

nikklg [1K]

Answer:

C. 1

Step-by-step explanation:

Looking to the Venn's diagram, we can realize that g(1) = 0

f(0) = 3√0 + 1

f(0) = 3•0 + 1

f(0) = 1
