Answer:
the last one
Step-by-step explanation:
the formula is AS= 2(Pi)r^2 + 2(pi)rh r^2= r x r
the r is 3 because Radis is half of the dynamiter
and pi= 3.14
the h(ight) is 14
plug in the #'s
2(3.14)3^2+2(3.14)3 x 14
Answer:
8(7+4) (C.)
Step-by-step explanation:
First find the biggest number thta can go into 56 and 32:
8!
Since C. is the only one that has an 8 out in the front, let's try that one:
So C. Is correct!
Answer:
Infinite or 2
Step-by-step explanation:
Since, we can take any side we want, infinite number of triangles can be formed.
However, if more than one similar triangles aren't allowed, then the value is (3-1)! = 2! = 2.
850.
68,750 = 350(75) + 50x
68, 750 = 26,250 + 50x
-26250
42,500 = 50x / 50
850 = x
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
