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
Answer:
12.9 hours.
Step-by-step explanation:
First, do 2.15 hours multiplied by 2, for each day. Then, multiply 4.30 by the 3 for 3 weeks.
Answer:
Law of cosines to find missing measures
c^2= a^2+ b^2 - 2ab*cos(C)
Used because it is a SAS triangle
Step-by-step explanation:
This is known as a side, angle, side, or SAS triangle. We can find the missing measures by using the Law of cosines
c^2= a^2+b^2-2ab*cos(C)
Answer:
A=36 square units
Step-by-step explanation:
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.
