<u>ANSWER</u>: 110
<u>EXPLANATION</u>:
Let these five numbers be a, b, c, d and e.
Then "<span>arithmetic means of 5 numbers is 100" implies
(a + b + c + d + e) / 5 = 100
>> a + b + c + d + e = 500
</span>And "arithmetic means of 2 of these numbers (suppose a and b) is 85" implies
(a + b) / 2 = 85
>> a + b = 170
Using these two equations, we have
(a + b) + c + d + e = 500
>> (170) + c + d + e = 500
>> c + d + e = 500 - 170
>> c + d + e = 330
So "t<span>he mean of the other 3 numbers (c,d and e)" is
</span>(c + d + e) / 3 = 330 / 3 = 110
Answer:
258 cm
Step-by-step explanation:
Given:
Distance from the base of the pole to the base of a tent guy line is
Length of a tent guy line is 359 cm
To find: Height of the upright tent pole
Solution:
Let AB denotes the pole and AC denotes a tent guy line.
According to Pythagoras theorem, in a right angled triangle, square of hypotenuse is equal to sum of squares of other two sides.
Therefore,
2parts compost and 10pats potting soil
2/10=1/5 which is 1 to 5 ratio.
He wants to end up with 6 kilograms which is 1 kg compost and 5kg of plotting soil.so he can use 1 kg compost

Bryan will have to spend 19 days on vacation if he expects to take 1 picture per day. Since he already took 1 at home and he is taking 1 per day, 19 plus the one he already took would equal 20 pictures.
Hope this helps!
