Answer:
Step-by-step explanation:
Her base salary is $1900 ,
and she makes an additional $70 for every copy =N
total pay = P
P= 1900 + 70 N
Plug N=29
I can't see the instructions, so I assume you're solving for the variable to the right.
(a)
A = pi*r(l+L), first divide both sides pi*r
A/(pi*r) = l + L, next subtract l from both sides
L = A/(pi*r) - l
(b)
V = pi*r^2*h, first isolate the variable r by dividing both sides by pi*h
V/(pi*h) = r^2, next take the inverse operation of square, which is the square root
r = sqrt root [ V/(pi*h)], assume r is a positive number only, so you do not need to consider the - square root option
(d)
t = 2*pi*sqrt (L/g), first divide both sides by 2*pi to isolate the radical
t/(2*pi) = sqrt (L/g), next square both sides to remove the radical sign over L
[t/(2*pi)]^2 = L/g, last multiply both sides by g
L = g*[t/(2*pi)]^2
(e) (actually it should say KE for kinetic energy)
E = (1/2)mv^2, multiply both sides by 2 and divide both sides by m
2*E/m = v^2, next take the inverse operation of square, square root of both sides
v = sqrt [2*E/m], again assume v is a positive quantity, although velocity is a vector quantity and should indicate both magnitude and direction
Answer: Option 'E' is correct.
Step-by-step explanation:
Marginal utility is the addition utility derived from each successive unit of a particular good.
so, marginal utility is the change in utility from consuming an addition unit of a good or service.
Mathematically, it is expressed as
Hence, Option 'E' is correct.
Answer:
4x4x4 = 64 cubic ft
1 cubic foot = 7.48 gallons
64 x 7.48 = 478.72 gallons
