$7.92
I do believe on the information given that this is the answer
It helps them when they have either really big numbers or really small numbers and so they don't have to use so many zeroes
Answer:
(1+y^2) /2y
Step-by-step explanation:
arithmetic mean is the average of x and y
(x+y)/2
Using the equation
xy = 1
and solving for x
x = 1/y
Replacing x in the first equation
(1/y + y) /2
Multiply by y/y
(1/y + y) /2 * y/y
(1/y + y)*y /2y
(1+y^2) /2y
Answer:
90 balls
Step-by-step explanation:
Set up proportion
36/x = 40/100
Cross multiply: 40x=3600
Solve for x
x=90
To check work:
40 percent of 90 would be 36
90(0.4)=36
Answer:
v = 176
Step-by-step explanation:
Since a fraction is essentially the same thing as dividing one number by another, we can multiply 44 by 4, the denominator of the fraction we are finding the numerator for, and get 176. This fraction is already in negative form, so we don't need to do anything else.
