You could use them to add 154 to 237 (using a flat, 5 longs and 4 units to make 154 and 2 flats, 3 longs and 7 units to get 237). Then once you've put them together, you'll count 391 (you'll have to move the decimal back to 3.91 to get <span>the answer).</span>
Answer:
I HAVE THE same question i need helpp ty ;/
Step-by-step explanation:
Answer:
Step-by-step explanation:
We have
To prove that by induction
Let P(n) be that statement for n
n=1 gives left side =1 =right side
True for n=1
Assume that P(k) is true
i.e.
We have to prove P(k+1) is true assuming P(k)
LHS of
RHS =
since by adding last term with Ck gives the sum
For simplification take (k+1) square outside
RHS =
Thus proved by mathematical induction
Answer: There are 32 pints of first type and 128 pints of second type in mixture.
Step-by-step explanation:
Since we have given that
Percentage of pure fruit juice in first type = 60%
Percentage of pure fruit juice in second type = 85%
Percentage of pure fruit juice in mixture = 80%
We will use "Mixture and Allegation" to find the ratio of first and second type in mixture:
First type Second type
60% 85%
80%
------------------------------------------------------------------------
85-80 : 80-60
5% : 20%
1 : 4
so, the ratio of first and second type is 1:4.
Total number of pints of mixture = 160
Number of pints of mixture of first type in mixture is given by
Number of pints of mixture of second type in mixture is given by
Hence, there are 32 pints of first type and 128 pints of second type in mixture.
Ok so first of all do you mean Hours and second of all What do you mean By 3/10?
