A.) y= 5/4x+16
B.) 1.25 hours a day
Answer:
27,600
Step-by-step explanation:
We use the following formula:-
Number of permutations of r from n
= nPr
= n! / (n-r)!
I am assuming you don't allow repeated letters in the 4 letter codes.
Take S as the first letter. Then we have 3 letters extra out of 25 letters.
Using the above formula the possible ways of doing this is
25! / (25 - 3)!
25! / 22!
= 25*24*23
= 13800.
The same number is obtained if the first letter is a T.
So the answer is 2*13800
= 27,600
3 as in 3 layers of skin is that what you were talking about hope this helps plus the 1 layers is epidermous 2 is dermis and 3rd is tissue
The elephant that weighs 2.85 tons
<span>For computing this, follow this method:
4 loads of stone weigh 2/3 ton.
4loads---------------------2/3
1load---------------------?
So it will be computed as 1x 2/3 /4 = 2/3x4= 1/3x2=1/6
the weight of 1 load of stone is 1/6 ton
Hope this helps. Let me know if you need additional help!</span>
