Answer:
-12
Step-by-step explanation:
4 1/2 - 5 1/8 = -0.625
7.5 x -0.625 = -12
Answer: 21
Step-by-step explanation:
Given: Number of mango guava and sapota are supplied 108,84 and 60 respectively.
Since, 108 = 2 x 2 x 3 x 3 x 3
84 = 2 x 2 x 3 x 7
60 = 2 x 2 x 3 x 5
HCF(108,84,60) = 2 x 2 x 3 [HCF=Highest common factors]
= 12
Greatest number of plants in each row = 12
Number of rows for mango =
Number of rows for guava =
Number of rows for sapota =
Total rows = 9+7+5= 21
Hence, the minimum number of rows in which they can be planted if in each row same numbers of saplings of the same type are to be planted = 21

I believe its c
Step-by-step explanation:
Volume of the Cylindrical bar, V = pi * r^2 * h
V = pi * 200^2 * 9
V = 22/7 * 40000 * 9
Let's assume the radius of the sphere as r
Volume of the sphere V1 = 4/3 * pi * r^3
V1 = V
V1 = 4/3 * pi * r^3
22/7 * 40000 * 9 = 4/3 * 22/7 * r^3
r^3 = (40000 * 9) * 3/4
r^3 = 10000 * 9 * 3
r = ( 10 * 10^3 * 3^3)^(1/3)
r = 10^(1/3) * 10 * 3
r = 2.154 * 30
r = 64.63 cm

Answer:
p = 3/4n +3
Step-by-step explanation:
Expressing the given equation in terms of powers of 3, we have ...
(27^(n+3))/(81^(p-1)) = 3
(3^3)^(n+3)/(3^4)^(p-1) = 3^1 . . . . as powers of 3
3(n +3) -4(p -1) = 1 . . . . . . . . . . . . log base 3 (or, equate exponents)
3n +9 -4p +4 = 1 . . . . . . . . . . . . . eliminate parentheses
3n +12 = 4p . . . . . . . . . . . . . . . . add 4p -1
p = 3/4n +3 . . . . . . . . . . divide by 4
