A) in 4 hours he can go 4*2 = 8 miles
and circular area = pie * R^2 = 3.14 * 8 * 8 =200.96 = 201 square miles
in 5 hours , area = pie* 10*10 = 3.14 * 100 = 314 sq mile.
additional area = 314 -201 = 113
hope it helped
24/200×100/100 = 12/100 = 12%
Answer:
1 1/5 or 12/10
Step-by-step explanation:
310+910=?
The two fractions have like denominators so you can add the numerators.
Then:
3+910=1210
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 12 and 10 using
GCF(12,10) = 2
12÷210÷2=65
The fraction
65
is the same as
6÷5
Convert to a mixed number using
long division for 6 ÷ 5 = 1R1, so
65=115
Therefore:
310+910=1 1/5
