He can give away 4 3/4 of a candy which would be 3 candy bars. He would have 1/2 a candy bar to himself.
Answer:
20
Step-by-step explanation:
Let the number of sides be n
One exterior angle = 360/n
Exterior angle + interior angle = 180
Interior angle = 180 - Exterior angle
= 180 - 360/n
Sum of interior angle = n(180 - 360/n) = 3240
n(180 - 360/n) = 3240
180n - 360 = 3240
180n = 3240 - 360
= 3600
n = 3600/180
= 20
Answer:
The percentage is
Step-by-step explanation:
From the question we are told that
The mean is
The standard deviation is
The weight Scott can bench is x = 145 pounds
Generally the percentage of statisticians that can bench more than Scott is mathematically represented as
=>
From the z table
The area under the normal curve to the right corresponding to 0.13043 is
=>
Converting to percentage
=>
10 quarts of 20 % salt solution mixed with 5 quarts of 80 % salt solution to make 15 quarts of 40 % salt solution
<em><u>Solution:</u></em>
The final mixture is 15 quarts
Let amount of 20% solution to be mixed, be x
Then, the amount of 80 % solution to be mixed is 15 - x
Thus, we can say,
"x" quarts of 20 % salt solution mixed with (15 - x) quarts of 80 % salt solution to make 15 quarts of 40 % salt solution
thus, we frame a equation as,
Thus 10 quarts of 20 % solution is mixed
Then, 15 - x = 15 - 10 = 5
5 quarts of 80 % salt solution is mixed
