110 members of a sports club play at least one of d games football, basketball nd volley ball. if 20 play football and basketbal
Phoenix [80]

\boldsymbol{\mathbf{Answer}}

\boldsymbol{\mathbf{67\,members\, play\, basketball \, altogether}}

\boldsymbol{\mathbf{Step-by-step explanation}}

As Given ,

Members play football and basketball = 20

Members  play football and vallyboll = 15

Members play basketball and volleyball = 26

Members play all games = x

Members play only one game = 2x

There are total number of members  = 110

From above data we can write,

110 = 20 + 15 + 26 + x + 2x + 2x + 2x

110 = 61 + 7x

7x = 110 - 61

7x = 49

x = 7members

To find,

Member play basketboll altogether

= 20 + 26 + 2x + x

We know that x = 7,

= 20 + 26 + 14 + 7

=  67 members

\boldsymbol{\mathbf{Member\, play\, basketboll\, altogether\, is\, 67\, members }}

Please help!! Local wildlife experts have begun to track the population of trout in their area. The function f represents the ap
jeka57 [31]

Answer:

Option C.

Step-by-step explanation:

We know that

f(t) = 1.5t + 50

represents the approximate population of trout in Sky Lake

And

g(t) = 0.1t^2 - 4t + 70

represents the approximate population of trout in Lake Cyan

The total trout population in the area is described as

f(t) + g(t)

f(t) + g(t) =  [1.5t + 50] + [0.1t^2 - 4t + 70]

f(t) + g(t) =  [1.5t + 50+ 0.1t^2 - 4t + 70]

f(t) + g(t) =  [0.1t^2 -2.5t + 120]

f(t) + g(t) =  0.1t^2 -2.5t + 120

Option C.
