Answer:
5/16
Step-by-step explanation:
Each number can happen in exactly one way (one sets the digit of tens and the other of ones).
We know that the law of divisibility by 3 is "sum of digits has to be divisible by 3", so let's examine the numbers:
11
13
15 - Yes
17
31
33 - Yes
35
37
51 - Yes
53
55
57 - Yes
71
73
75 - Yes
77
So it's 5 out of 16 options.
We could do it by examining the relation and modulus shifts with each digit, but for 16 numbers it's seriously faster to just list them.
8:30 because the 8:50 one is twenty minutes fast, the 8:00 one is half an hour off, and the 8:20 one is slow.
9.945*10^30 Kg - 1.7901*10^32 Kg
This is on average what the mass of a black hole.
Answer: it nearest 25 and 26:)

Answer:
The equation to determine the total length in kilometers is
The total length in kilometers of Josh’s hike is 38 km.
Step-by-step explanation:
Given:
Let the total length in kilometers of Josh’s hike be h.
Now Given that He has now hiked a total of 17 km and is 2 km short of being 1/2 of the way done with his hike.
It means that to reach half of the length of total length Josh needs 2 more km to add in his hiking which is done which is of 17 km.
Framing the above sentence in equation form we get;
Hence, The equation to determine the total length in kilometers is
Now Solving the above equation we get;
First we will multiply 2 on both side using Multiplication property we get;
Hence, The total length in kilometers of Josh’s hike is 38 km.
