Constant of proportionality is the constant value of the two proportional quantities, in this problem p and s, where 4 is the factor of proportionality because it is constant or k.
In simple terms, p is in direct proportion to s wherein the increase or decrease in value of s results to the increase or decrease in value of p with 4 the only factor remaining unchanged.
In the above problem, the number 4 is derived from the word square. We all know that a square has 4 sides of equal lengths, therefore, the perimeter is equivalent to the product of 4 and its lenght.
We should find the mean number of the tests.
This would be done like: (23+24+25)/3 = 24
After that, you should find the percentage or fraction like this 24/50
Then use the fraction as an estimate like this:
(24/50) * 3250 = 1560
The correct answer is 1560.
Answer:
the answer is 3.37723077E13
Step-by-step explanation:
Step-by-step explanation:
Formula is:
x=(-b± √b^2-4ac)/2a
a= 1
b= -8
c= 17
x= (-(-8)±√64-4(1)(17))/2
x= (8±√-4)/2
now
x1= (8+√-4)/2
x2=(8-√-4)/2
Answer:
y= 10
Step-by-step explanation:
-3x-5y=4
+3x +3x
-5y=7x
+5y +5y
y= 10
