Answer:
33
Step-by-step explanation:
Answer:
36. m = (3/2)n
37. s = 5tv
38. c = 3/d
Step-by-step explanation:
Each of the variations in these problems has its own associated equation. You only need to make use of the given values to find the constant of variation (k) and fill in the equation.
- direct variation: y = kx; k = y/x
- joint variation: z = kxy; k = z/(xy)
- inverse variation: y = k/x; k = xy
_____
36. The constant for direct variation is the ratio of the given values:
k = m/n = 18/12 = 3/2
Then the equation for the direct variation is ...
m = (3/2)n
___
37. The constant for the joint variation is the expression ...
k = s/(tv) = 8/((4/5)·2) = 8/(8/5) = 8·5/8 = 5
Then the equation for the joint variation is ...
s = 5tv
___
38. The constant for the inverse variation is the product of the given values:
k = cd = (1/4)(12) = 3
Then the equation for the inverse variation is ...
c = 3/d
1/100 This is because every percent is out of 100.
The answer is 60pi
The entire circle circumference covers 360 degrees.
The arc EF only takes 30 degrees.
The arc EF is 30/360 of the total circumference.
Arc EF is 5pi units.
The entire circumference is (5pi)/(30/360) = 60pi
You use math like when u are in a grocery store and u want to scan the weight of an item you need the fraction
