Answer:
its either A or C
Thats the best i could do
Step-by-step explanation:
Farmer has 7 choice for cow out of which he choose only 2
4 choice for pig and he choose only 3 pigs
10 choice for sheep and he choose all 10 sheep
Number of ways of choosing cows = 7C2
Number of ways of choosing pigs = 4C3
number of ways of choosing sheep = 10C 10
all these three groups of different animals can make different groups when taken together
That is : 7C2 * 4C3 * 10C10 = 21 * 4 * 1 = 84 ways
Answer : 84
Answer:
Let's define:
A = # of students in group A
B = # of students in group B
C = # of students in group C.
"The total number of students who could attend a field trip is represented by the variable t."
This can be written as:
A + B + C = t.
"The number of students in Group A is less than the number in Group B."
Here we have a strictly "less than", then this is written as:
A < B.
"Group A has 6 students more than 1/4 the total number of students"
A = t/4 + 6
"Group B has 3 less than the total number of students"
B = t - 3.
Then we have the equations:
A + B + C = t.
A = t/4 + 6
B = t - 3.
A < B.
We could replace the second and third equatio in the fourth one, to get:
t/4 + 6 < t - 3.
t/4 + 9 < t
9 < t - t/4
9 < t*(4/4 - 1/4)
9 < t*(3/4)
(4/3)*9 < t
12 < t.
Then we found an inequality that defines the minimum possible value of t,
We would factor this
what 2 numbers multiply to get -12 and add to get -4?
-6 and 2
(x-6)(x+2)
the side lengths are (x-6) and (x+2)
Answer:
Step-by-step explanation:
It is given that the pressure, P, of the given mass of a gas in a closed cylinder varies inversely as the volume, V, of the cylinder.
Therefore, P ∞
So, where k is the constant of proportionality.
Hence, the equation that models the given statement is :
or
PV = k
