Answer:
The amount that came is 
Step-by-step explanation:
The computation is shown below:
According to the question, it is mentioned that
Multiply 4 by 
First open the equation in a fraction it would be 
Now multiplied the above fraction by a 4
That gives the result of
Hence, the amount that came is
We simply multiply the 4 with the given fraction
Thus the above represents the simplest form of the fraction
Answer:
Unit rate is often a useful means for comparing ratios and their associated rates when measured in different units. The unit rate allows us to compare varying sizes of quantities by examining the number of units of one quantity per one unit of the second quantity. This value of the ratio is the unit rate.
X=10 and y=5 so it's the first option
Answer:
see explanation
Step-by-step explanation:
Given x varies directly as y then the equation relating them is
x = ky ← k is the constant of variation
To find k use the condition x = 9 when y = 4
k = 
= 
= 2.25
x = 2.25y ← equation of variation
When y = 8, then
x = 2.25 × 8 = 18
Using the distance formula:
Distance = √((x2-x1)^2 + (y2-y1)^2)
Distance = √((5-2)^2 + (-8 - -4)^2
Distance = √(3^2 + -4^2)
Distance = √(9 +16)
Distance = √25
Distance = 5
