Answer:
There are 286 possible combinations
Step-by-step explanation:
To solve this problem we must use the formula of combinations.
Where n is the number of players that there are and elect r of them
In this case there are 7 + 6 = 13 players and you choose 10 of them
Then we look for 13C10
There are 286 possible combinations
Answer:
67
Step-by-step explanation:
Number: AB
A = B-1
BA + AB = 143
10*B + A + 10*A + B = 143
11A + 11B = 143
A + B = 13
(B-1) + B = 13
2B = 14
B = 7
A = 6
The number is 67
check: 6 = 7-1 and 67 + 76 = 143
34.8=1/2(10)(b)sin(56)
34.8 = 5bsin(56)
34.8/5 = bsin(56)
6.96 = bsin(56)
6.96/sin(56) = b
8.3952769216 = b
I assume we must round off to the nearest tenths place.
Doing so we get b = 8.40
Answer:
-x+4
Step-by-step explanation:
given that
(x^3-4x^2+7x-28)÷(x^2+7)
or
first (x^2+7) × -x = -x^3-7x
so (x^3-4x^2+7x-28) + (-x^3-7x) = -4x^2-28
agian (x^2+7)×(4) = 4x^2+28
so, (-4x^2-28) + (4x^2+28) = 0
