By definition we have the following equation:
t = d / v
Where,
t: time
d: distance
v: speed
For this case we have:
d / 30 + d / 4 = 17
Rewriting we have:
2d + 15d = 17 (60)
17d = 17 (60)
d = 60 mi
Then, the walking time is
t = d / v
t = 60/4
t = 15 hours
Answer:
She walked
t = 15 hours
Answer: x = 13.5
3/4 = x/18
⇔ x = 3/4 .18 = 27/2 = 13.5
Step-by-step explanation:
Answer:
a = 2
b = 3
c = 8
Step-by-step explanation:
<em>2^5/4</em>=<em>2^5/2a</em>=<em>2^b</em>=<em>c</em>
<em>2^5/4</em>, 2^5 = 32, 32/4 = 8
so c, being what all of this is equal to, is 8
<em>2^5/2a</em>, 2*2=4
so a = 2
<em>2^b </em>= 8, ∛8 = 3
so b = 3
Hope my explanation makes sense :)
It’s correct. i like your handwriting btw, it’s really pretty
Answer:
P(A) = 0.57 (to the nearest hundredth)
Step-by-step explanation:
There are 7 letters in total
4 of them are the letter A
⇒ P(A) = 4/7
= 0.5714285714...
= 0.57 (to the nearest hundredth)
