We have been given that a hiker begins in a valley at 150 feet below sea level. When the hiker reaches the highest point on the trail, he is 579 feet above sea level. We are asked to find change (in feet) in elevation of the hiker.
To find change in hiker's elevation we will subtract hiker's initial elevation from hiker's elevation at the end of trail.
We are subtracting negative 150 because at the beginning of trail hiker was 150 feet below sea level.
Therefore, the change in hiker's elevation is 729 feet.
Answer:
The number is 25
Step-by-step explanation:
Of is multiply and is means equals
70% *W = 17.5
Change to decimal form
.70 W = 17.5
Divide and .70
.70W/.70 = 17.5/.70
W =25
<span>elements in Set A, B and C. Set A, B and C have some elements in common. If 16 elements are in both A and B, 17 elements are in both A and C, and 18 elements are in both B and C, how many elements do all these three of the sets A, B and C have in common? 1.</span>

Remember that <u>dividing by a number is the same as multiplying by its reciprocal.</u> To get a number's reciprocal, flip the numerator and denominator around.
In this case, 3/5's reciprocal is 5/3. With this information in mind, flip 3/5 to it's reciprocal, change the division sign to multiplication, then multiply as such:
<u>Your final answer is 35/24.</u>

Now firstly, we want to convert these mixed fractions into improper fractions. To convert them, multiply the whole number by the denominator then add the numerator and that's your new numerator. In this case:
Next, we want to convert this expression to multiplication. Similar to before, convert 6/5 to its reciprocal, change the multiplication sign to division, and multiply as such:
Now you may think that 105/60 is the right answer, however we can simplify it further. The numerator and the denominator have a GCF, or greatest common factor, of 15. With this, divide the fraction by 15/15 as such:
<u>Your final answer is 7/4.</u>
