Answer:
22221
Step-by-step explanation:
I set up the problem like this
823
x27
Then I multiplied 7 by 3 and carried over the one and then multiplied 7 by 2 and added one and carried the one over... I then multiplied 7 by 8 and added the one!
Then I put a zero where the 7 I first multiplied would be... I then multiplied 2 by 3 and then multiplied 2 by 2 and finally multiplied 2 by 8!
I then added up the two values! (Sorry this probably sounds confusing!)
The base b of a logarithmic function should be greater than zero and not equal to 1. Therefore, the first and second choice is the only ones left possible:
b> 0 and b = 1
b > 0 and b=/ 1
but it was stated earlier that the value of b should not be equal to 1, therefore, the answer is
b > 0 and b =/ 1<span />
Draw ΔABC as shown in the figure below.
m∠B = 137°, b = 14, c = 9.
From the Law of Sines,
sin(C)/c = sin(B)/b
or
sin(C)/9 = sin(137°)/14
sin(C) = (9/14)*sin(137°) = 0.4384
m∠C = arcsin(0.4384) = 26°
Because the sum of angles in a triangle is 180°, therefore
m∠A = 180 -137 - 26 = 17°
From the Law of Sines,
a/sin(A) = b/sin(B)
or
a/sin(17°) = 14/sin(137°)
a = (sin(17°)/sin(127°))*14 = 6
Answer:
The solution for the triangle is
a = 6, b = 14, c = 9
m∠A = 17°, m∠B = 137°, m∠C = 26°
The question is a little confusing, so bare with me.
The part that throws me off is the "same number of girls and boys". Does each individual group need the same amount of girls to boys, or does each group need the same amount of girls and boys as the other groups? I'm assuming it's the latter, as "all of the children are in a group, but I'll solve it both ways.
The first way, there can only be twelve groups. A boy and a girl in each group so it's equal, and 24 boys sit out.
The second way, the answer is 16. Each group will have two boys and one girl. So each group will have three kids. 12 plus 36 is 48, and 48 divided by 3 is 16.
Hope this helped, and feel free to ask more questions.
