Answer:
see the explanation
Step-by-step explanation:
Let
x ----> number of tennis balls
y ----> number of tennis rackets
we know that
To find out the ratio of tennis balls to tennis rackets, divide the number of tennis ball by the number of tennis rackets
In this problem we have
see the model in the attached figure N 1
so
This is the equation of a linear direct variation
The relationship between the variables x and y is proportional
see the model in the attached figure N 2
Answer:
y^18
Step-by-step explanation:
(y^2)^5 x y^8
Assuming the x is multiplication
We know (a^b)^c = a^(b*c)
(y^2)^5 = y^(2*5) = y^10
We are multiplying this by y^8
We know a^b * a^c = a^(b+c)
y^10* y^8 = y^(10+8) = y^18
Assuming the x is a variable
We know (a^b)^c = a^(b*c)
(y^2)^5 = y^(2*5) = y^10
We are multiplying this by y^8
We know a^b * a^c = a^(b+c)
y^10* y^8 = y^(10+8) = y^18
This is multiplies by x
x y^18
Dividing by 10 is simple; just move the decimal place one digit to the left. So, 8.0 would then be 0.8. However, it is imperative you show your working out:
8/10=0.8
Divide 72 by 6, and then by 9. Your answers will be there.
I think it is the first one
