7/4=(4+3)/4=4/4+3/4=1+3/4=1 3/4.
Answer: 7/4 is as a mixed number 1 3/4.
If is the distance the runner travels between first and second base, then the distance between him and home plate satisfies
(where the 90 here refers to the distance between first base and home)
Differentiating both sides with respect to time gives
The runner's speed is . When he is away from first base, he is
away from home plate. So he is moving away from home plate at a rate of
This are fractions because they are not mixed fraction by the way those two are 0.5
Answer: a<13
Step-by-step explanation:
a*(a+1)<a^2+13
a^2+a<a^2+13
subtract a^2 from both sides:
a<13
