So these are decmials of the accutal total so
.32=32%
what makes this question easy is that there are 200 members so to convert the percents into accutall numbers so like .32=32%=64 people (since 200 is 2 times of 100)
A. fiction of 31-40 compared to 21-30
fiction 31-40=.38=38%=76 readers
fiction 21-30=.32=32%=64 readers
76-64=12
A is FALSE
B. so we want to know how many people are 31-40 and prefer fiction
so .38=38% and 38% of 200=76
B is FALSE
C 43 members are 21-30
so we look at the total row for the 21-30 people and see that .43 or 43% or 86 people are in the 21-30 age group
C is FALSE
D. 140 members prefer fiction
look at the total column for fiction and see that .70 like fiction .70=70%=140 people
D is TRUE
so A,B,C are FALSE
D is TRUE
He can make 3 pieces. Since he has 8/10 of a candy bar, it is then simplified to 4/5 of a candy bar. You need to find 1/3 of that, that is 4/15. Then how many times does 4/15 fit into 4/5, well simply do this: (4/15)x=4/5. Solving for x should give you 3.
To convert miles to feet you multiply by 5280
To convert hours to seconds you divide by 3600
so you multiply 64 by 5280/3600 which comes to 93.87 ft/s Answer
26,300 = 1/2x + 3200......with x being last years population
I think your diagram had an error because the instruction says that it is a SQUARE frame with sides that are 8 inches long.
Anyways, following the question, the area of the shaded parts should be:
2(8 x 2) + 2(8 - 2 - 2)(2)
= 32 + 16
= 48 sq in.
